Tempisquitoneura, a New Genus of Neotropical Orthocladiinae (Diptera:Chironomidae) Symphoretic on Corydalus (Megaloptera:Corydalidae)

Abstract

The adult male, adult female, pupa, and larva of a new genus (Tempisquitoneura) of midge (Diptera:Chironomidae) are described and illustrated from specimens collected and reared from Corydalus (Megaloptera:Corydalidae) in northwestern Costa Rica. Larvae and pupae of the midge live attached to the Corydalus larvae. The genus belongs in the Corynoneura group of the subfamily Orthocladiinae, but its relationship to the two other described genera in the group (Corynoneura and Thienemanniella) will remain unclear until more Neotropical members of this group are described and analyzed in all life stages.
