Abstract

Opeatocerata Melander is revised based on primary types of the following species: O. rubida (Wheeler and Melander, 1901) (holotype female), O. stubbsi Smith, 1989 (holotype male), O. cooperi Smith, 1989 (holotype female), O. lopesi Smith, 1989 (holotype male), O. melanderi Câmara and Rafael, 2011 (holotype male) and O. trilobata Câmara and Rafael, 2011 (holotype male). It has a Neotropical distribution, the specimens varying from 2 and 5 mm in length and predominantly yellow. Here it is been described and illustrated 15 new species: Opeatocerata agudeloi sp. nov. (Colombia, Amazonas), O. ampullaria sp. nov. (Brazil, Amazonas), O. bare sp. nov. (Brazil, Amazonas), O. brasiliensis sp. nov. (Brazil, Goiás, Mato Grosso, Pará), O. cylindrophallus sp. nov. (Brazil, Mato Grosso), O. curvipenis sp. nov. (Costa Rica, La Suiza, San Mateo), O. hadrophallus sp. nov. (Brazil, Amazonas), O. hypandriociliaris sp. nov. (Brazil, Pará), O. megalophallus sp. nov. (Costa Rica, San Mateo, Guanacaste), O. mourai sp. nov. (Brazil, Amazonas), O. nhamunda sp. nov. (Brazil, Pará), O. smithi sp.nov. (Brazil, Amazonas), O. spinipenis sp. nov. (Brazil, Amazonas), O. tanimboca sp. nov. (Colombia, Amazonas; Brazil, Amazonas) and O. zuleideae sp. nov. (Brazil, Amazonas). An illustrated dichotomous key and maps with geographical records are presented. Phylogenetic analysis demonstrated the monophyly of Opeatocerata and it is presented a phylogenetic relationships hypothesis among species.
