Current Arrangement

A new erebid, Tabwecala robinsonigen. nov., sp. nov., from the Vanuatu Islands (Espiritu Santo) (West Pacific Ocean) is described. The new species, superficially resembling species of the genera Artena, Achaea or Leistera, shows a peculiar combination of characters which suggested its placement in a new genus. This is provisionally placed in tribe Poaphilini but following a review of the features purporting to show the separation of Ophiusini and Poaphilini, it is shown that morphological rationale supporting the current arrangement of these tribes is still lacking. Noteworthy modifications affect the hindleg of male Tabwecala robinsoni, with greatly shortened and swollen metatibia bearing a dorsal hair-pencil.

A New Species

A detailed description and figures of a new species Entokrohnia entiptera sp. nov. are presented. Diagnoses of the families Protoeukrohniidae fam. nov. and Tokiokaispadellidae Salvini-Plaven, 1986, and all the three genera of the latter family: Tokiokaispadella Kassatkina, 1980, Aberrospadella Kassatkina 1971, and Entokrohnia gen. nov. are given.

Three New Species

Three new species of the genus Lestidium with complete lateral line are described from the Indo-west Pacific Ocean. Lestidium longilucifer sp. nov., from Western Australia and Taiwan, belongs to the Lestidium atlanticum species complex and can be separated from other congeners by having 41–43 prehaemal vertebrae, 85–88 total vertebrae and 126–146 total lateral-line scales; and body proportions. Lestidium australis sp. nov. from eastern Australia and Lestidium rofeni sp. nov. from Taiwan and the Philippines together with Lestidium prolixum form the L. prolixum species complex. These three species can be separated from each other by a combination of different fin positions, vertebral formula, number of lateral-line scales and pigmentation.

Six species of the gutless marine tubificid genus Olavius Erséus, 1984 (Phallodrilinae), O. paraloisae sp. nov., O. amplectens sp. nov., O. isomerus sp. nov., O. fidelis sp. nov., O.lifouensis sp. nov., and O. nivalis sp. nov., are described from shallow-water sediments in New Caledonia (including the Loyalty Islands), in the South West Pacific Ocean. Olavius amplectus is similar (but not necessarily closely related) to a North West Atlantic species. The others appear closely related to previously described taxa in the Indo-West Pacific region, but they differ in the number of secondary body annuli, the number, shape and arrangement of chaetae, or in details of the male genitalia and/or spermathecae. Moreover, fixed (contracted) specimens of O. nivalis measured up to 34 mm length, which makes it one of the largest species of gutless Phallodrilinae known to date.
