New genera and species, and new records of Tasmanian Trichoptera (Insecta)

Abstract

Examination of Trichoptera specimens collected in Tasmania over the last 25 years has led to a revision of the Trichoptera list for Tasmania, and expansion of the distributions of many species, particularly those in the World Heritage areas. The following 17 new species are described: Poecilochorema anastemum, T aschorema dispatens, Ptychobiosis iconica, Chimarra derogata, Hydrobiosella tahunense, H. anatolica, H disrupta, H propinqua, H scalaris, H otaria, Daternomina quastrulla, D. jacksonae, Cheumatopsyche deani, C. alampeta, Diemeniluma serrula, Marilia aenigmata and T asmanthrus gwendolensis. There are also three new combinations - Taschorema ithyphallicum Schmid, Daternomina irrorata Kimmins and Diemeniluma tasmanica Jacquemart. New genera are established for Daternomina (Family Ecnomidae) and Diemeniluma (Family Hydropsychidae).
