Two new Neotropical Chironominae genera (Diptera: Chironomidae)

Abstract

Claudiotendipes n. gen. and Sigmoitendipes n. gen. are described and figured based on adults, pupae and larvae. Two species are included in Claudiotendipes: the type species, C. froehlichi n. sp. from Bahia, Rio de Janeiro, Sao Paulo and Santa Catarina States in Brazil; and C. epleri n. sp. from Costa Rica. Five species are included in Sigmoitendipes, all from Brazil: the type species, S. susanae n. sp. from Sao Paulo, Mato Grosso, Amazonas and Para States; S. fittkaui n. sp. from Mato Grosso and Para; S. reissi n. sp. from Sao Paulo; and S. oliveirai n. sp. and S. spiesi n. sp., both from Mato Grosso. A cladistic analysis grouped the two new genera with Beardius, Oukuriella and Endotribelos. Keys to the males of the two new genera are presented.
