Mozambique, Polynoe inhaca, was doubtfuUy placed in Polynoe {sensu latu) by DAY (1951:15), based on its superficial appearance to Polynoe scolopendrina. Based on additional specimens from the same area, DAY (1957:62) refeired his species to Allmaniella. Then after further study. DAY (1962:634) erected the new genus Pseudopolynoe for the species emphasizing the terminal position of the three antennae arising from the prostomium at the same level, as in Lepidonotus. Pseudopolynoe was included in the subfamily Lepidonotinae by FAUCHALD (1977:65). The genus is herein refeired to Lepidasthenunae PETITBONE, 1989, based on the different types of parapodia and elytra. In Lepidastheniinae the neuropodia are truncate distaUy and notched dorsally forming subequal anterior and posterior lobes, and lacking projecting presetal acicula^ obes, as m Lepidonotus. Based on a specimen of Polynoe inhaca from near the type locahty, kmdly sent on loan in 1966 by the late John H. DAY, the description of the genus and species is supplemented.
