Description of Caprionchulus diversipapillatus n.gen., n.sp. from Caprivi, Namibia (Nematoda: Onchulinae)

Abstract

Caprionchulus diversipapillatus n.gen, n.sp. was found in a small fresh-water pond in eastern Caprivi. The new genus differs from all other genera within the subfamily Onchulinae Andrássy, 1963 in the almost barrel- shaped stoma containing a single dorsal tooth, an elongated cardia comprising three vertical rows of four cells each and peculiar supplements consisting of two conspicuous adanal setae and a row of six to eight papilloid supplements, the last four of which are in pairs. The spicule shape is also different from other members of the Onchulinae.
