A new species of Colosmittia Andersen et Sæther from Costa Rica (Chironomidae: Orthocladiinae)

Abstract

Colosmittia anamariae sp. n. from Costa Rica is described and figured as male imago. The genus Colosmittia Andersen et Sæther, 1994 was described based on a single species, C. clavata Andersen et Sæther, 1994 from the West Usambara Mountains in Tanzania, East Africa. A second species, C. brasileira Mendes et Andersen, 2009 was recently described from Brazil. The discovery of a third species in Costa Rica indicates that the genus might be widespread in the Neotropical region.
