  • In the microcaddisfly family Hydroptilidae, only 12 species belonging to four genera are known currently from the Korean Peninsula. Yet, worldwide this family is one of the biggest of the Trichoptera families. Collection from 2015 to 2017 by aerial sweeping and light-trapping in the southeastern part of Korean Peninsula (Gyeongsangbuk-do and Gyeongsangnam-do) included species not recorded previously from the Korean Peninsula. We provide re-descriptions of the six species(Hydroptila dampfi Ulmer, 1929, H. introspinata Zhou and Sun, 2009, Orthotrichia costalis(Curtis, 1834), O. tragetti Mosely, 1930, Oxyethira miea $Ol{\acute{a}}h$ and Ito, 2013, and Stactobia nishimotoi Botosaneanu and Nozaki, 1996) to improve comprehension of Korean hydroptilids.

  • In the family Hydroptilidae, Trichoptera, 11 species in 3 genera, Hydroptila Dalman, 1819, Oxyethira Eaton, 1873 and Stactobia McLachlan, 1880, have been recorded from the Korean Peninsula but, until now, no species in the genus Orthotrichia Eaton, 1873. In this paper, we describe a new Korean species, Orthotrichia coreana sp. nov., based on adult specimens from the middle reaches of rivers in the southern region of the peninsula. This species is similar to O. iriomotensis Ito, 2013 from the southernmost region of Japan, but is clearly discriminated from the latter by features of the male and female genitalia.
