A Revision of the Australian Funnel-web Spiders (Hexathelidae: Atracinae)

The Australian funnel-web spiders of the subfamily Atracinae are revised. The Atracinae are divided into three genera-Atrax O.P.-Cambridge with three species (two new), Hadronyche L. Koch with 31 species (18 new), and Illawarra n.gen. with one new species. Hadronyche is divided into four species groups-the lamingtonensis, adelaidensis, infensa and cerberea groups. Fourteen previously described species are redescribed or diagnosed. Twenty one new species are described: Atrax sutherlandi n.sp., A. yorkmainorum n.sp., Illawarra wisharti n.sp., Hadronyche alpina n.sp., H. emmalizae n.sp., H. marracoonda n.sp., H. monaro n.sp., H. tambo n.sp., H. nimoola n.sp., H. mascordi n.sp., H. jensenae n.sp., H. orana n.sp., H. lynabrae n.sp., H. kaputarensis n.sp., H. levittgreggae n.sp., H. macquariensis n.sp., H. walked n.sp., H. raveni n.sp., H. lamingtonensis n.sp., H. annachristiae n.sp. and H. monteithi n.sp. Two species described from Melanesia, H. hirsuta Rainbow and Styphlopis insularis Rainbow, are regarded as nomen dubia.
