ABSTRACT. The objective of this study was to determine the taxonomic composition and ecological aspects of decapods crustacean species belonging to the infraorders Anomura and Brachyura in shallow marine and estuarine waters from southern Bahia, a coastline about 640 km in extent, corresponding to approximately 7% of the Brazilian coast. Sixteen species of the infraorder Anomura and 68 of the infraorder Brachyura are reported for the study area. The most important families in terms of number of species were the Panopeidae with 11 species, and the Ocypodidae and Portunidae with 9. Among the Brachyura, the southern distribution of the species Austinixa leptodactyla Coelho, 1997 (Pinnotheridae), endemic to Brazil, is extended from the coast of Sergipe to Bahía (Prado, Cumuruxatiba Beach, 17°06'18.6"S, 39°10'50.4"W). The ocypodid Uca (Leptuca) cumulanta Crane, 1943 and also the pinnotherids Austinixa aidae (Righi, 1967) and Fabia byssomiae (Say, 1818) are reported for the first time from the Bahia coast. The specimen of F. byssomiae examined was collected in the mantle cavity of the clam Macoma constrict (Bruchiére, 1792) (Bivalvia: Tellinidae), a new host record for the species.

Keywords: diversity, marine biota, Anomura, Brachyura, southwestern Atlantic, Brazil.


RESUMEN. El objetivo del presente estudio fue determinar la composición taxonómica y aspectos ecológicos de los crustáceos decápodos pertenecientes a los infraórdenes Anomura y Brachyura, en aguas someras, marinas y estuarinas del sur de Bahia, Brasil, una línea costera con cerca de 640 km de extensión, que corresponde aproximadamente al 7% de la costa brasileña. Para esta area de estudio se registraron 16 especies del infraorden Anomura y 68 del infraorden Brachyura. Las familias más representativas en términos de número de especies fueron Panopeidae, con 11 especies, y Ocypodidae y Portunidae, ambas con nueve especies. Entre los Brachyura, la distribución meridional de Austinixa leptodactyla Coelho, 1997 (Pinnotheridae), endémica del Brasil, se extiende desde la costa de Sergipe hasta la costa de Bahia (Municipalidad de Prado, Playa de Cumuruxatiba, 17°06'18.6"S, 39°10'50.4"W). Se reportó por primera vez para Bahia el ocipódido Uca (Leptuca) cumulanta Crane, 1943, al igual que los pinotéridos Austinixa aidae (Righi, 1967) y Fabia byssomiae (Say, 1818). El único espécimen de F. byssomiae fue recolectado al interior de la cavidad paleal del molusco Macoma constricta (Bruchiére, 1792) (Bivalvia: Tellinidae), representando un nuevo huésped para esta especie.

Palabras clave: diversidad, biota marina, Anomura, Brachyura, Atlántico suroccidental, Brasil.


INTRODUCTION

The southern Bahia coast, between the cities of Válela and Mucuri, is approximately 640 km long and represents about 7% of the Brazilian coast (Ferreira, 1976). This long tropical coastline includes one of the largest bays in Brazil (Camamu) (Oliveira et al. 1998, 2002) and the most extensive reef complex in the South Atlantic (Abrolhos) (Leao, 2002), in addition to estuaries of several major rivers (Coritas, Pardo, Jequitinhonha, and Mucuri), comprising a great diversity of coastal environments that supposedly shelter high species richness, which is incompletely described. Until 2003, no projects had aimed to survey, intensively and systematically, the decapod crustacean fauna in this area; the previous records were few and intermittent. As a result, this area constitutes a gap in the distribution of many decapods (Almeida et al. , 2007a), which impedes the analysis of the geographical distributions of species.

Between 2003 and 2008, several projects sponsored by the Universidade Estadual de Santa Cruz (UESC), Ilhéus, Bahia, Brazil, were carried out to survey the crustacean fauna in coastal areas of the southern part of the state. Another project on species inventory, linked to the Universidade Estadual do Sudoeste da Bahia (Jequié Campus) was carried out in Camamu Bay. These studies allowed the documentaron of new records of decapods in Bahia and the extensión of the known southern distributions for some species (Almeida et al, 2006, 2007a, 2007b, 2008a, Almeida & Coelho, 2008), as well as the description of a new species (Fransen & Almeida, 2009). To group the material collected in these inventories, a crustacean collection was established at UESC in 2003, which currently contains just over 1,300 lots.

The objective of this study was to determine the taxonomic composition and ecological aspects of the decapod crustacean fauna belonging to the infraorders Anomura and Brachyura in shallow marine and estuarine waters of southern Bahia. Because of their abundance and ecological importance, these crabs are important members of tropical benthic communities. In addition, some species [e.g., Callinectes spp., Car disoma guanhumi Latreille, 1825, Goniopsis cruéntala (Latreille, 1803), and Ucides cordatus (Linnaeus, 1763)] have great socio-economic importance in the study area, being exploited by the artisanal fishery and providing a livelihood for many families.

MATERIAL AND METHODS

The material examined in this study was collected on the southern coast of Bahia, especially during the projects "Inventariamento da Fauna de Crustáceos Decápodos do Municipio de Ilhéus, Bahia" (2003-2005) and "Diversidade de Crustáceos do Sudeste e Sul da Bahia, Brasil: I. Ambientes Costeiros" (2006-2008). The sampling methods for the material obtained during the first project in estuaries of Ilhéus were described by Almeida et al. (2006). The study area in the second project extended from Cairú (13°34'S, 38°54'W) to Mucuri (18°05'S, 39°33'W) in the southernmost part of the state, on the border with Espirito Santo (Fig. 1). Collection activities were approximately trimestral and covered almost all the coastal municipalities, with the exception of Ilhéus (the target of the first project). The sampling stations were distributed along this coastline in order to cover the largest possible number of coastal habitats such as sand beaches and sand-mud fíats, mangroves, rocky shores, and sandstone and coral reefs (Fig. 2). Samples were qualitative, with no standardization effort, and conducted in the intertidal and shallow subtidal zones during the low water of spring tides. Manual capture was the most common method used. Crustaceans were sought in micro-habitats of marine and estuarine environments, such as burrows in sand and mud, decomposing leaves and twigs, among roots and trunks of mangrove trees, on and under rocks, on artificial substrata, and in association with algae and marine invertebrates. Traps such as the "siripóia" (a type of handmade crab trap) were frequently used to catch crustaceans in the shallow sublittoral (e.g., Callinectes spp.). All stations sampled in this project were geo-referenced. At the time of capture, data on bottom type, salinity (measured with the aid of an optical refractometer), and host (when possible) were recorded.

The list of species at each sampling station between 2003 and 2008, including all the projects mentioned above, is given in Appendix 1. The specimens are deposited in the carcinological collection of the Museu de Zoologia of the Universidade of Santa Cruz (MZUESC), Ilhéus. For each species examined, the geographical distribution, ecological notes (when possible, derived from field observations), and previous records in Bahia, including the synonyms (if any) under which the species was mentioned for the study area are given. The list of material examined reports the municipalities from north to south. When more than one lot refers to a given municipality, the order increases according to the number of the lot in the MZUESC collection. The survey of the previous records of decapod species from Bahia was based on an exhaustive analysis of the literatee effectively published through 2009. Thus, restricted information sources such as monographs, dissertations, theses, and meeting communications were not included, ñor were publications on biology and fisheries. Comments on taxonomy (including recent taxonomic changes), geographical distribution, and historical aspects were added when appropriate. For Brachyura, the classification proposed by Ng et al. (2008) was followed, and for other Decapoda the system of Martín & Davis (2001) was used, to the family level. The order of species within each family (or subfamily if applicable) is alphabetical.

The longitudinal and latitudinal distribution patterns were classified based on the proposal of Melo(1985). Melo(1985) recognized that some species from the Virginian, Carolinian, and Antillean patterns have northern and southern populations (in south-eastern Brazil) separated by 30°, 45°, and 50°, respectively. Here, the species are treated as having disjunct distributions, following the work of Coelho & Ramos (1972), where the gap in the distribution corresponds at least to the Guyana región (Guyanas, Amapá, and Para).

Remarks: Calado (1998) reported Bahia as the southern limit for this species in the western Atlantic, but did not mention the locality. Mucuri, the southernmost limit of the study area (18°05'20.7"S, 39°33'14.6"W), may represent the southermost collection locality of E. portoricencis to the present.

Material examined: 2m, 01.VIII.2008, Cairú, Boipeba Island, Triana River, MZUESC 1275; 2m, 1f, 28.VIII.2007, Caravelas, Caravelas River, St. 1, MZUESC 961; 8m, 4f, 28.VIII.2007, Caravelas, Caravelas River, Farol Abrolhos late Clube, St. 2, MZUESC 964; 5m, 4f, 29.VIII.2007, Caravelas, Caravelas River, Barra de Caravelas, St. 4, MZUESC 968; 1f, 28.VIII.2007, Caravelas, Caravelas River, St. 1, MZUESC 1091. See also material cited by Almeida et al. (2006).

Distribution: Western Atlantic: Florida, Cuba, Co10m bia, Venezuela, French Guyana, and Brazil (Maranhão to Santa Catarina). Eastern Mediterranean: Egypt and Israel. Widely distributed in the Indo-Pacific (Mantelatto & Dias, 1999; Tavares & Amouroux, 2003; Feres et al, 2007).

Ecological notes: Intertidal to 51 m. Mainly on soft bottoms, but also on hard substrata such as rocks and coral (Lemaitre, 1995). In the southern Bahia, the species was collected in estuaries, on a mud bottom, on a sand-mud bottom with broken shells, under tree trunks and rubble, and on the octocoral Carijoa riisei on a jetty. Salinity range: 24-38.

Previous records in Bahia: Carqueija & Gouvêa (1996), Todos os Santos Bay; Almeida et al. (2003, 2007a), Camamu Bay; Almeida et al. (2006), Ilhéus; Almeida & Coelho (2008).

Remarks: Invasive swimming-crab, a native of the Indo-Pacific (Campos & Turkay, 1989; Lemaitre, 1995), a good example of a successful introduced marine species in the western Atlantic (Tavares & Amouroux, 2003). It was recorded for the first time on the coast of Bahia by Carqueija & Gouvêa (1996), in Todos os Santos Bay. Later, Almeida et al. (2003) obtained a specimen in Camamu Bay. A juvenile crab was collected in the estuary of Cachoeira River, Ilhéus (Almeida et al. 2006). Almeida et al. (2007a) reported the collection of 16 specimens at five stations, from July 2003 to September 2005, at Camamu Bay. Here we report the occurrence of C. hellerii at two additional localities, Boipeba Island and Caravelas. It appears that this crab is extremely abundant in the estuary of the Caravelas River, where it was found in a wide variety of microhabitats, including on the octocoral C. riisei. On the coast of Bahia the species has been reported only in bays and estuaries with wide mouths, with a strong marine influence.

Central Atlantic: Ascension and Saint Helena. Eastern Atlantic: Gabon, São Tomé and Príncipe, and Annobon islands (Kropp & Manning, 1987; Melo, 1996; Nogueira, 2003).

Ecological notes: Shallow waters to 75 m, in corals of the families Astrocoeniidae, Siderastreidae, Faviidae, Oculinidae, Meandrinidae, Mussidae, and Caryophylliidae (Kropp & Manning, 1987; Melo, 1996). The specimens were collected in reef areas, forming galls in the coral Mussismilia hispida (Verrill, 1901) (Anthozoa: Mussidae) (Fig. 4b), at a salinity of 39.

Previous records in Bahia: Utinomi (1944); Coelho (1966); Coelho & Ramos (1972); Barrete et al. (1993); Almeida & Coelho (2008).

Remarks: Some records of T. corallicola in hosts of the family Agariciidae in northeastern Brazil are doubtful (Coelho, 1966; Coelho & Ramos, 1972). The species involved is probably another cryptochirid known from the Brazilian coast, Opecarcinus hypostegus (Shaw & Hopkins, 1977) (see Kropp & Manning, 1987). The association of this gall-crab with M. hispida was documented by Coelho (1966) (as M. cf tenuisepta, see Kropp & Manning, 1987 and Nogueira, 2003).

Previous records in Bahia: Almeida et al. (2006) and Bento et al. (2007), Ilhéus; Almeida & Coelho (2008).

Remarks: G. guanhumi has been known from Bahia since the book "Tratado Descritivo do Brasil em 1587", literally "Descriptive Treatise of Brazil in 1587", by Gabriel Soares de Sousa, first published in 1851. Sousa's work intended mainly to bring to the attention of the Portuguese authorities the richness of the land of Bahia, the risks of its occupation by foreigners, and the benefits of an expedition to better explore Brazil. The book includes detailed information on diverse themes such as physical geography, mineralogy, ethnology, zoology, and botany. Several decapods, including freshwater, estuarine, and marine species are mentioned. Sousa mentioned Cardisoma guanhumi as a large blue land crab, called "guoanhamu" by the Native Americans (see Tavares, 1993).

Distribution: Western Atlantic: Florida, Cuba, and Brazil (Bahia, and from Rio de Janeiro to Rio Grande do Sul) (Campos, 1996; Melo, 2008; this study).

Ecological notes: From 5 to 25 m, on mud, sand, and shell bottoms. In Brazil, it has been recorded in association with the bivalves Anudara Gray, 1847 and Glycymeris Costa, 1778 (Melo, 2008), and in the northern hemisphere with Hiatella árctica (Linnaeus, 1767) and Anadara notabilis (Roding, 1798) (Campos, 1996). The specimen examined was collected within the mantle cavity of Macoma constricta (Bruchiere, 1792) (Bivalvia: Tellinidae) (new host record), on a mud bottom, at a salinity of 24.

Previous records in Bahia: None.

Remarks: Melo(2008), listing the brachyurans from Ilha Grande, Rio de Janeiro, mentioned the occurrence of F. byssomiae in that región. However, Melodid not discuss the possible synonymy with F. emiliai (Melo, 1971). The status of the latter species in the western Atlantic is still unclear (Dr. E. Campos, pera. comm.). Fenucci (1975) found a pair of pinnotherids in a bivalve of the genus Glycymeris. The female specimen was identified as F. insularis, and the male as F. emiliai, both described by Melo(1971). Based on the third pair of maxillipeds and on the shape of the ambulatory legs, Fenucci (1975) concluded that the two specimens were conspecific. After an analysis of the type material of Melo's (1971) species, Fenucci (1975) concluded that the holotype of F. emiliai was in fact the male of F. insularis. As F. emiliai, in Melo's (1971) publication, had been treated before F. insularis, the former species had priority over the latter, being considered its sénior synonym. Later. Martins & D'Inção (1996) pointed out that both species should be recognized as valid, after they examined a male specimen of F. insularis. These authors commented that the male of this species was very similar to the female, differing from it by having the abdomen smaller than the sternum. The characterization of the male gonopods was incom-plete, because the first pair had the tip damaged. According to Dr. E. Campos (pers. comm.) the supposed male of F. insularis described and figured by Martins & D'Inção (1996) is a subadult female (females and males in the genus Fabia Dana, 1851 are sexually dimorphic), and their conclusions were therefore not scientifically supported. Campos (1996), in his partial revisión of Fabia, commented that F. byssomiae, of which only the female is known, and F. emiliai are morphologically very similar, and suggested that the latter could represent a hitherto unrecognized junior synonym of the former. However, the supposed synonymy between F. byssomiae and F. emiliai suggested by Campos (1996) was based on the descriptions available at that time (Dr. E. Campos, pers. comm.). After the publication of his 1996 article, Campos has recognized some possible differences between these two species based on the figures available (the carapace in F. byssomiae is sub-circular and the abdomen is not posteriorly produced, whereas in F. emiliai the carapace is sub-quadrate and the abdomen is posteriorly produced) (Dr. E. Campos, pers. comm.). The specimen from southern Bahia (CLxCW = 5.2x6.1 mm), although it had suffered damage to the carapace and abdomen before its fixation, has a sub-circular carapace, with two longitudinal grooves that originate from the superior margin of the orbit. The abdomen is not posteriorly produced. The shape of the third maxilliped is as represented by Campos (1996, p. 1160, fig. Ib) for F. byssomiae (Figs. 9h-9i). The cutting edge of the dactylus of the cheliped is armed with a strong proximal tooth (Figs. 9a-9c). The third pair of pereiopods is asymmetrical: the right is longer than the left, because their articles are proportionally longer (Fig. 9d, 9f). Thus, our specimen matches the main characteristics of F. byssomiae. In the Systema Brachyurorum, Ng et al. (2008) considered both species as synonyms, perhaps following Campos' (1996) proposal. It is possible that Melo(2008) referred the species from Ilha Grande to F. byssomiae, following Campos' (1996) suggestion and Ng et al. (2008). Collection and description of the males is highly important to clarify the taxonomic status of these species, because the shape of the abdominal somites and the telson are unique in each species within the genus Fabia.

Distribution: Western Atlantic: Massachusetts to Florida, Gulf of Mexico, West Indies, and Brazil (Ceará to Santa Catarina) (Melo, 1996, as Z. ostreum; Bezerra et al, 2006, as Z ostreum).

Ecological notes: All individuáis were collected in the mantle cavity of Crassostrea rhizophorae. Salinity range: 4-24. Also found in association with the bivalves Crassostrea virginica (Gmelin, 1791), Anomia simplex Orbigny, 1842, Mytilus edulis (Orbig-ny, 1846), and Pectén sp. Occasionally in polychaete tubes, mainly Chaetopterus variopedatus (Renier, 1804) (Powers, 1977; Melo, 1996).

Previous records in Bahia: Zaops ostreum -Martins & D'Inção (1996), Itaparica Island; Almeida & Coelho (2008).

Patterns of Distribution

Based on the patterns of geographical distribution proposed by Melo(1985), the 16 anomurans collected have amphi-American (n = 2), circumtropical (n = 1), or western Atlantic (n = 13) longitudinal patterns of distribution (Table 1). Among the western Atlantic species, the majority have a latitudinal distribution of the Antillean pattern (8 species), but the Central-South American (n = 2), Brazil endemic (n = 2), and Virginian (n = 1) patterns are also represented (Table 1).


The 68 brachyurans obtained fit into four patterns of longitudinal distribution: amphi-American (n = 2), amphi-Atlantic (n = 6), circumtropical (n = 2), and western Atlantic (n = 57) (Table 2). A single nonindigenous species has been reported from the Bahia coast, Charybdis hellerii (see discussion in the

"Taxonomy" section). Possible means of introduction of this portunid in the western Atlantic have been exhaustively discussed (Campos & Türkay, 1989; Lemaitre, 1995; Tavares & Mendonça Jr., 1996, 2004; Tavares & Amouroux, 2003). Among the western Atlantic species, a greater part have the Antillean pattern of latitudinal distribution (26 species). The other species represented are Carolinian (n = 14), Central-South American (n = 8), Virginian (n = 6), or endemic to Brazil (n = 4) (Table 2).



DISCUSSION

Of the 53 species of Anomura known from Bahia (Almeida, 2009), ranging from the intertidal to the deep continental slope, only 16 were recorded in this study. None of them represents a new record for the fauna of the state.

Almeida & Coelho (2008) reviewed the brachyuran fauna of Bahia and listed a total of 162 species for the state's coast, ranging from the intertidal to bathyal waters. To this list are added the species Sotoplax robertsi (Almeida et al, 2008a), Homologenus rostratus A. Milne-Edwards, 1880 (Homoloidea: Homolidae), and Rochinia crassa Tavares, 1991 (Majoidea: Epialtidae), the last two not included by Almeida & Coelho (2008) but reported by Serejo et al. (2007). In this study, Uca (Leptuca) cumulanta, Austinixa aidae, A. leptodactyla, and Fabia byssomiae are reported for the first time. Thus, the brachyuran fauna of Bahia is currently composed of 169 species.

Almost 30% of the brachyuran species reported for the Bahia coast have their southern limits of distribution in the western Atlantic between the states of Bahia and Rio de Janeiro, suggesting that this area constitutes a transition zone between the Brazilian and Paulista zoogeographic provinces (Almeida & Coelho, 2008). The deepening and regression of coralline algae bottoms that occurs to the south of Abrolhos (Kempf, 1970, 1971) certainly acts as a thermal and edaphic barrier to a certain group of species adapted to this type of substratum, limiting their distribution. Almeida & Coelho (2008) also commented on the possible influence of the belt formed by the relatively large watersheds on this part of the Brazilian coast, such as those of the rivers Jequitinhonha, Pardo, Doce, and Paraíba do Sul, as a seasonally limiting factor of distribution for stenohaline species. However, this región seems to have little zoogeographical importance for the coastal species reported in this study, since only 10 species (two anomurans and eight brachyurans) have their southern limits of distribution corresponding to this stretch of Brazilian coast (see Tables 1 and 2). For 74 of the 84 species studied, the southem limit of distribution in the westem Atlantic is located in the Argentinean and Paulista provinces (between São Paulo and the Argentina coast), which are influenced in winter by the cold waters of the Malvinas Current, the Píate River discharge, and the Subtropical Convergence (Melo, 1990; MeloFilho, 2006). Thus, this región represents a thermal barrier to the southward progression of these southem species in the westem Atlantic.

According to Coelho et al. (1978), each province in the southem hemisphere has an equivalent in the northem hemisphere, and the Antillean and Brazilian provinces are equivalent, especially due to the similar climate (low annual thermal gradient). Just over 40% of species collected in the study area (part of the Brazilian Province) have latitudinal pattems of distribution of the Antillean type, showing the close relationship between these two tropical faunas. However, considering the totality of the decapod fauna from the westem Atlantic, the number of species from the Caribbean región is almost double that found in the Brazilian province (including the Guianas region), the second most species-rich province (Boschi, 2000). The marine fauna of tropical América derived from the Tertiary Caribbean province, which included the eastem tropical Pacific to the formation of the Panamá Isthmus at the end of the Pliocene. The speciation events that took place after the final closing of the isthmus there about three million years ago, combined with the displacement of warm-water species from north to south during the Pliocene (from Florida, for example), may explain the large concentration of species in the Antilles (Werding et al, 2003).

Among the westem Atlantic species, a contingent of 22 species of the 70 studied (31.4%) have a disjunct distribution, including Virginian, Carolinian, and Antillean species (Tables 1 and 2). The gap in the distribution of these species corresponds at least to the Guianas región, mainly characterized by the predominance of soft bottoms (mud and sand), strongly influenced by freshwater discharge from major rivers of the Equatorial región, such as the Orinoco, Amazon, and Tocantins (Coelho, 1969; Coelho & Ramos, 1972). In this case, the gap in the species distributions would be due to ecological causes. On the other hand, this gap may represent an artifact. The composition of the crustacean fauna of this coastal area remains less known, and perhaps some of the species considered disjunct, in fact occur in the Guianas región although they have not yet been collected there.

Another factor to be considered is that some of the species with disjunct distributions may represent pairs of cryptic species, which are common in the marine environment, including some decapod groups (see Knowlton, 1986, 1993; Anker, 2001; Machordom & Macpherson, 2004; Asakura & Watanabe, 2005, Hiller et al. , 2006; Rodríguez et al. , 2006). Based on the distribution of reef fishes, for example, Floeter & Gasparini (2000) suggested the recognition of two provinces in the western Atlantic. To the north, the Northwest Atlantic province (or Caribbean expanded), including from the Florida east coast to Cape Harteras and Bermuda, and the Brazilian province to the south, extending to the southeast of Brazil and separated from the Caribbean by the freshwater barrier formed by the mouth of the Amazon River. The rate of endemism of the Brazilian province is high (about 18%) for this shallow-water species group. The Amazon barrier acts as a primary barrier in relation to the dispersal of shallow-water reef organisms, and is so effective for reef fishes that only some species associated with sponge bottoms in the ocean waters can overeóme it (Collette & Rützler, 1977; Floeter & Gasparini, 2000). This conclusion is also applicable to the distribution of porcellanid crabs in the western Atlantic, since few intertidal and shallow subtidal species oceur on both sides of this barrier (Werding et al. , 2003). Among the species with disjunct distri-butions reported in this study, some are abundant in shallow-water environments where hard substrata oceur, such as the anomurans Calcinus tibicen and Clibanarius antillensis, and the brachyurans Epialtus bituberculatus, Microphrys bicornutus, Pilumnus dasypodus, Eurypanopeus abbreviatus, and Panopeus harttii, for which the river discharge in the Guianas región may represent an ecological barrier, restricting gene flow and perhaps leading to speciation. Many of these belong to taxa that require extensive taxonomic revisión (e.g., Pilumnidae, Panopeidae), especially given the context of the existence of cryptic species in several groups of marine crustaceans. Thus, it is to be expected in the coming years that the study of cryptic biodiversity, supported by detailed morphological examination of specimens throughout their ranges and the use of molecular tools, will allow the description of numerous new taxa for science.

In agreement with Tavares (2004), the major part of the carcinological collections in Brazil is quite recent and these samples still have to be properly studied. As a result, few Brazilian specimens have been compared with material from other geographical areas. On several recent occasions, when comparative material from outside Brazil was available, the Brazilian specimens that had been considered to be identical to those from the Caribbean proved to belong to new species (Tavares, 2004).
