New species of the genus Corynoneura Winnertz (Diptera, Chironomidae) from Brazil

Seven new species of the genus Corynoneura Winnertz from small streams in the Atlantic Forest are described; Corynoneura fortispicula sp. n., Corynoneura hermanni sp. n., Corynoneura mediaspicula sp. n., Corynoneura mineira sp. n., Corynoneura septadentata sp. n., Corynoneura sertaodaquina sp. n., Corynoneura unicapsulata sp. n., as male, female, pupa and larva. Diagnosis and drawings of other two morphotypes based on female, pupa and larva are given. Larvae were collected from rocks, leaves and debris near the water surface and were reared. Males here described are defined by the phallapodeme sclerotized on posterior margin, females usually have labia fused as funnel.

A review of the genus Corynoneura Winnertz (Diptera: Chironomidae) from the Neotropical region

Currently the genus Corynoneura Winnertz comprises 10 species already cited or described for the Neotropical region. In the present paper 15 new species are described for the Neotropics: 12 new species are described from Brazil, five of them are described as male, female, pupa and larva, Corynoneura canchim sp. n., C. diogo sp. n., C. espraiado sp. n., C. humbertoi sp. n., C. salviniatilis sp. n.; three as male, pupa and larva, C. franciscoi sp. n.; C. longiantenna sp. n. and C. renata sp. n.; the species C. sisbiota sp. n. as male, female and pupa; C. bodoquena sp. n. as male and pupa and C. boraceiasp. n. and C. vidiapodeme sp. n. as males. Corynoneura trondi sp. n. is described from Chile (male, pupa), C. guanacaste sp. n. from Costa Rica (male) and C. zempoala sp. n. from Mexico (male). The knowledge of the distribution of Corynoneura fortispicula, C. sertaodaquina, C. septadentata and C. unicapsulata all species described by Wiedenbrug and Trivinho-Strixino (2011) as well as Corynoneura ferelobata Sublette et Sasa is extended. A larval morphotype is also included. Keys for males, females, pupae and larvae to known species of the Neotropical Corynoneura are given.
