Description of the type species of the genus Goerodes and generic assignment of three East Asian species (Trichoptera, Lepidostomatidae)

Abstract

After critical examination of specimens from several localities in Japan, I synonymize Goerodes toyotamaensis (Kobayashi) with G. corniger Ulmer, the type species of the genus. I redescribe the male, female, larva, and larval case of G. corniger and describe the pupa and egg for the first time. I reconfirm the generic assignment of G. albardanus (Ulmer), G. elongatus (Martynov), and G. sinuatus (Martynov), which were placed in Dinarthrodes by some authors, based on the similarity of their larvae with those of other species of Goerodes, including the type species. I synonymize Crunobiodes koreaensis Kobayashi, originally described from Korea, with G. sinuatus.
