ANDERSEN, Trond; MENDES, Humberto Fonseca  e  HAGENLUND, Linn Katrine. A new species of Colosmittia Andersen et Sæther from Costa Rica (Chironomidae: Orthocladiinae). Biota Neotrop. [online]. 2011, vol.11, n.3, pp. 211-213. ISSN 1676-0603.  http://dx.doi.org/10.1590/S1676-06032011000300019.

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.
