Threatened Trichoptera (caddisflies) from the Tasmanian Wilderness World Heritage Area

Abstract

Trichoptera were collected in the Tasmanian WildernessWorld Heritage Area (WHA) between November 1998 and February 1999 usingautomatic UV light traps, sweep nets and aquatic hand-picking. The surveys targeted the four species listed on the Tasmanian ThreatenedSpecies Protection Act 1995 which had been recorded from the WHA: Taskiria mccubbini, Taskiropsyche lacustris (both endangered),Orphninotrichia maculata (rare) and Oxyethira mienica (rare). In total 88 species were identified, approximately half of the 174 speciesnow known from Tasmania. Taskiria mccubbini and Taskiropsyche lacustris were recorded for the fi rst time since they were first collectedfrom the original Lake Pedder in 1965. Orphninotrichia maculatawas recorded from a new location. Diplectrona Iyella (rare) was recordedfrom two widely separated sites and is a new threatened species record for the WHA. One species ofEcnomidae was newly recorded fromTasmania.
