Abstract

This final paper in a series reviewing Australian members of the long-horned caddisfly genus Oecetis McLachlan (Trichoptera: Leptoceridae) deals with 21 species, 13 of them new, and all assigned here to the pechana-group, so-named for the most common and widespread of Australian Oecetis species. This group is diagnosed as having fork 1 in the forewing sessile and, in the male, scale patches on the forewing and a single internal paramere in the phallus, although in several species one or other of these male features is absent. Keys are given to the Oecetis species groups recognised in Australia and to species in the pechana-group. Established pechana-group species are diagnosed and new species are described. Male genitalic features are illustrated for all species save O. lurida Kimmins which was described from a female and is probably a doubtful name. A homonym created in the name O. dilata Wells, 2004 is replaced with the name Oecetis kimberleyensis nom. nov., and Oecetis cepaforma Wells, 2004 is synonymised with the widespread Oriental-Australian O. hemerobioides McLachlan, 1866. Seventy-four Oecetis species are now recognised in the Australian fauna.
