The 18 species of finless snake eels of the genus Apterichtus (family Ophichthidae, subfamily Ophichthinae) are reviewed. Included are: A. anguiformis from the Mediterranean and eastern Atlantic; A. ansp from the Carolinas to Brazil in the western Atlantic; A. australis from South and Central Pacific islands, including Japan; A. caecus from the Mediterranean and eastern Atlantic; A. equatorialis from the eastern Pacific; A. flavicaudus from Hawaii, Midway Island, and possibly Australia and Seychelles; A. gracilis from the eastern central Atlantic; A. hatookai from Japan and China; A. kendalli from the western Atlantic and St. Helena Island; A. klazingai from South Africa to Hawaii; A. monodi from the eastern Atlantic; A. moseri from Japan; and A. orientalis from Japan. Five new species are described and illustrated: A. dunalailai from Vanuatu and Fiji at 291–450 m; A. jeffwilliamsi from Vanuatu at 4–16 m; A. malabar from New South Wales, Australia at 44–66 m; A. mysi from the Marquesas Islands at 35–64 m; and A. nariculus from Ambon Island, Indonesia at 28–30 m. A neotype is designated for Apterichtus caecus. An identification key is provided. The synonymy of the genus Apterichtus is reviewed. Apterichtus keramanus Machida, Hashimoto & Yamakawa 1997, is referred to Ichthyapus.

A molecular phylogenetic analysis of the genus Hippasteria, rooted against Evoplosoma, has provided the basis for taxonomic revisions and provided insight into the biogeography of a widely occurring, cold-water group of corallivorous asteroids. Herein, we describe three new species, Hippasteria mcknighti sp. nov., Hippasteria muscipula sp. nov., and Hippasteria tiburoni sp. nov., from deep-water settings. Additionally, in light of taxonomic changes, we further elaborate on distribution data for multiple species. Range extensions for Hippasteria phrygiana and Hippasteria californica are included. Discussions about biogeography, cladogenic events, and morphology are also presented.(c) 2014 The Linnean Society of London
