Abstract

MENDES, Humberto Fonseca  and  ANDERSEN, Trond. Iporangomberus pei n. gen., n. sp. from southeastern Brazil (Diptera: Chironomidae, Orthocladiinae). Biota Neotrop. [online]. 2011, vol.11, n.4, pp. 67-71. ISSN 1676-0603.  http://dx.doi.org/10.1590/S1676-06032011000400006.

Iporangomberus pei n. gen., n. sp. is described and illustrated based on an adult male from Mata Atlântica in southeastern Brazil. This genus can be separated from other Orthocladiinae based on the combination of hairy eyes; decumbent acrostichals starting close to antepronotum; bare wing; squama with few setae; R₄₊₅ ending distal to M₃₊₄; curved, apically spoon-shaped phallapodeme; and simple, subquadrangular gonostylus with well developed heel.
