Estudo taxonômico de curtonotidae duda, 1934 (diptera, ephydroidea), do Brasil

Abstract

Curtonotidae is a small family of hunchbacked flies with 101 valid species in four genera, one of which occurs in Brazil: Curtonotum. A taxonomic study of the Brazilian Curtonotidae fauna was conducted based on material borrowed from national and foreign institutions. The specimens were identified, dissected and illustrated. 825 specimens belonging to 12 species were examined, including two new species described here: Curtonotum aurifrons sp. n. and Curtonotum nigripene sp. n. Lectotypes were designated for two species: C. coriaceum Hendel, 1932 and C. decumanum Bezzi, 1914. Eight species were redescribed, based on type-material: Curtonotum coriaceum Hendel, Curtonotum decumanum Bezzi, Curtonotum perplexum Klymko & Marshall, 2011, Curtonotum atlanticum Klymko & Marshall, 2011, Curtonotum gracile Klymko & Marshall, 2011, Curtonotum nigrum Klymko & Marshall, 2011, Curtonotum pantherinum (Walker, 1849) and Curtonotum taeniatum Hendel, 1913. The number of species recorded from Brazil is now 20, corresponding to an increase of 12% in the knowlodge of the family in the country. An illustrated identification key, discussion of temporal distribution of the family and maps with geographical records are also provided.
