An ongoing revision of the dinematichthyine fishes (Ophidiiformes, Bythitidae, Brosmophycinae) of the Indo-west Pacific based on ca. 5000 specimens will be published in several parts. Part II includes 363 identified specimens in the genera Dermatopsis Ogilby, 1896 (D. greenfieldi n. sp. from Fiji, D. hoesei n. sp. from south-eastern Australia, D. joergennielseni n. sp. from New Zealand and D. macrodon Ogilby, 1896, from south-eastern Australia); Dermatopsoides Smith, 1947 (D. andersoni n. sp., D. kasougae (Smith, 1943) and D. talboti Cohen, 1966, from South Africa, and D. morrisonae n. sp. from Western Australia), and Dipulus Waite, 1905 (D. caecus Waite, 1905 and D. hutchinsi n. sp. from Western Australia, D. multiradiatus (McCulloch and Waite, 1918) from southern Australia, and D. norfolkanus Machida, 1993a, from Norfolk Island). Dermatopsis multiradiatus McCulloch and Waite, 1918, is reassigned to Dipulus. The three genera are distributed along the subtropical shores of South Africa, Australia, northernmost New Zealand and the Norfolk Island and the tropical shores of Fiji. The genera contain mainly fishes adapted to rocky shores as compared to the predominance of other Dinematichthyini found in reef environments. The three genera are indicated to be closely related, sharing characters such as a maxilla not expanded postventrally, the head without scales and lacking an upper preopercular pore. Dermatopsoides is further characterized by the lack of an exposed opercular spine (i.e. completely covered by skin), a character unique amongst Indo-west Pacific dinematichthyine genera. The main distinguishing characters of the species contained in these genera are vertebrae and fin ray counts, morphometric characters, head pores and the morphology of otoliths and pseudoclaspers.
