PARRA, LUIS E  and  PASCUAL-TOCA, MARTA. Taxonomic revision of the genera Oratha Walker 1863 and Hasodima Butler 1882 (Lepidoptera: Geometridae). Rev. chil. hist. nat. [online]. 2003, vol.76, n.1, pp.117-128. ISSN 0716-078X.

The genera Oratha Walker 1863 and Hasodima Butler 1882 from central and southern Chile are redefined and its species revised and described. The species are Oratha significata Walker 1863, H. elegans Butler 1882, H. boreas (Butler 1882) and H. bartletti sp. nov. The analysis of the types and the genitalia allow placing Aconcagua fessa Rindge in the synonymy of Aconcagua parva (Butler) comb. nov. All species and their genitalia and distribution are described and illustrated. A key for species of Hasodima is provided. The monophyly of the genera and its relationships to the allied taxa are briefly discussed.
