Tubiluchus lemburgi, a new species of meiobenthic Priapulida

With seven described species Tubiluchus is the most species-rich genus among priapulids. We here describe a new species, Tubiluchus lemburgi sp. nov., from the island of Tenerife (Canary Islands). All Tubiluchus species are very similar morphologically, but show distinct differences in the genital region of males. The new species differs from any other described Tubiluchus in the presence of a clearly demarcated genital region bordered by a cuticular ridge, the shape of the genital openings and the distribution of cuticular structures.
