Crasiella dipluragen. et sp.n. (Gastrotricha, Macrodasyoidea)

Abstract

A new marine macrodasyoid gastrotrich, Crasiella diplura, is described from the Bergen area, Norway. Among the characters which distinguish it are a pair of very small tail lobes and a marked asymmetry in the posterior third of the intestinal tract. As it combines characters met with in various families, the taxonomic placing is difficult. Provisionally it is placed in the family Lepidodasyidae.
