New species of the genus Corynoneura Winnertz (Diptera, Chironomidae) from Brazil Author Wiedenbrug, Sofia Author Trivinho-Strixino, Susana text Zootaxa 2011 2822 1 40 journal article 10.5281/zenodo.201167 9a665162-8afd-4900-8d74-c49e00eb179c 1175-5326 201167 Corynoneura sp. sexadentata ( Figs 24–25 ) Material examined. Three females with pupal and larval exuviae, BRAZIL , SP, Ubatuba, stream besides Ruínas da Lagoinha, 23˚30.468´S, 45˚11.923´W, 0 m a.s.l., 16.x.2008 , S. Wiedenbrug. One female with pupal and larval exuviae same data as before but stream besides Ruínas da Lagoinha, Cachoreira do Véu 23˚30.404´S, 45˚12.340´W, 116 m a.s.l., 29.xii.2009 (UFSCAR MPSW 057). Diagnostic characters. Female and pupa are not separable from C. septadentata , the only difference between both species is the larval mentum of sp. sexadentata that has six median teeth and instead of seven ( Fig. 25 E). Remarks. Unfortunately the male of this morphotype is still unknown. All females of C. sp. sexadentata were collected in Ubatuba (0 m a.s.l.), and specimens of C. septadentata in the Parque Estadual do Jaraguá (about 1000 m a.s.l.). It is possible that the difference on the mentum is a population variation, but only with the knowledge of the male and more material it would be possible to affirm that.
