Two new Neotropical Chironominae genera (Diptera: Chironomidae)

Trond Andersen, Humberto Fonseca Mendes, Luiz Carlos Pinho


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, São 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 São Paulo, Mato Grosso, Amazonas and Pará States; S. fittkaui n. sp. from Mato Grosso and Pará; S. reissi n. sp. from São 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.
