Revisão das espécies neotropicais de Larsia Fittkau, 1962 (Diptera: Chironomidae: Tanypodinae) e taxonomia de Tanypodinae Thienemann et Zavřel na Amazônia, Brasil

Abstract

The first chapter is a review of the Neotropical species of the genus Larsia. The species previously recorded for the neotropical region were redescribed and illustrated, in some cases it was not possible to analyze the material and their situations are discussed in the text. Thirteen species were described as new, and all with material from Brazil. Eight morphotypes were described, three based on males and 5 based on pupae of diferent locations in Central and South America. Keys to male, pupa and larva to those described neotropical species were prepared. The second chapter deals with the Tanypodinae subfamily in the Amazon. A total of 21 species belonging to 11 genera were analyzed, 3 of them were identified as Laurotanypus travassosi, Monopelopia caraguata and M. tenuicalcar, 2 were identified as Pentaneura, but described as morphotypes since only females were associated with immature and 14 species were described as new. Two species have been described as genus A and genus B, since it does not fit the description of any known group of Tanypodinae. Three genera, Clinotanypus, Denopelopia and Parapentaneura were recorded for the first time in the Amazon. Keys to male, pupa and larva of the genera found in the Amazon have been prepared. With these results the number of described species of Tanypodinae registered in Amazon increases from 19 to 44.
