Henicops Newport, 1844, is the most commonly recorded Australian genus of Henicopidae, the main southern temperate clade in Lithobiomorpha. Henicops is widespread throughout eastern and southwestern Australia and New Zealand, and is represented in New Caledonia by H. brevilabiatus (Ribaut, 1923) n.comb. New species are H. tropicanus n.sp. from northeastern Queensland and H. milledgei n.sp. from Victoria. The two nominal species from the southwest of Western Australia, H. dentatus Pocock, 1901a, and H. oligotarsus Attems, 1911, are synonymous, this species being distinguished from the Queensland H. tropicanus by details of the mandibular gnathal edge and female gonopod. Other characters used for diagnosing species and supraspecific groups within Henicops include the segmentation of the tarsi, tergite shape, and the position of the Tömösv&agrav;ry organ. All species of Henicopidae are listed with synonymies, generic assignments and geographic occurrences.
