Abstract

BAEZ R., Pedro  and  RUIZ L., Rosario. Puerulus and postpuerulus of Projasus bahamondei George, 1976 (Crustacea, Decapoda, Palinuridae). Investig. mar. [online]. 2000, vol.28, pp.15-25. ISSN 0717-7178.  http://dx.doi.org/10.4067/S0717-71782000002800003.

The puerulus and the postpuerulus stages of Projasus bahamondei, common name: Langosta de Valparaíso are described. The material was collected from the deep fisheries off Central Chile by trawlings in the captures of squat lobsters and shrimps. A certain variability was observed among the studied larval specimens and the postlarval ones. The size of these specimens are in general larger than the pueruli and postpueruli described form other palinurid species. P. bahamondei from the Chilean continental slope, Juan Fernandez archipelago and Desventuradas islands, and from the Nazca Ridge, together with P. parkeri from South Africa, New Zealand and Saint Paul Island from the Indian Ocean, and Projasus sp. from New South Wales, Australia, belong to a circumpolar genus, very old phylogenetically, which has a Gondwanic origin. The described stages of P. bahamondei are compared with those from P. parkeri and Projasus sp.
