Taxonomy and phylogeny

Abstract

Three new species and two new genera of Typhloplanoida from the Western Indian Ocean are described. Feanora brevicirrus gen. et.sp. n. is a member of the Trigonostomidae von Graff, 1905 sensu Den Hartog, 1964. It has a cirrus, paired ovovitellaria and an undifferentiated afferent duct. An excentric bursa opens in the fecundatorium and a large ovoid vesicle enters the afferent duct in its distal part. Gaziella pileola gen. et sp. n. and G. lacertosa sp.n. are two new members of the Promesostomidae Den Hartog, 1964. They have a long cirrus, ovovitellaria and a long muscular female duct with two excentrically placed sperm-receiving vesicles. Their most striking feature is the proboscis-like structure. Feanora and Gaziella are provisionally considered as genera incertae sedis within the resp. families.
