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. circulimentum ( Figs 22–23 ) Material examined. One female, with pupal and larval exuviae, Ubatuba, stream besides Ruínas da Lagoinha, 23˚30.468´S, 45˚11.923´W, 0 m a.s.l., 16.x.2008 , S. Wiedenbrug. Diagnostic characters. Adult females are separable from other species by the eyes pubescent, labia funnel shaped, one large and one small seminal capsule, both sclerotized and gonapophysis with posterior median margin straight ( Figs 22 B–C). Pupa are difficult to separable from C. sertaodaquina , but the shagreen is more similar to C. septadentata , having shorter spines, not elongated as in C. sertaodaquina ( Figs 23 A–C). Larva are distinguished from other species due to antennal length subequal to post-mentum length ( Fig. 23 E), Frontal apotome about 170 µm long, mentum with three median teeth ( Fig. 23 F), ventral setae on abdomen apically split ( Fig. 23 G), basal seta on posterior parapod with one pectinate side ( Fig. 23 H). Remarks. Unfortunately the male of this morphotype is still unknown. Pupa and larva are similar to C. septadentata and C. sertaodaquina . Not only the male but more material necessary to define this morphotype as a valid species.
