Studies on the Streptaxidae (Mollusca: Gastropoda Pulmonata) of Malawi9. Description of Gulella streptostelopsis, a new Streptostele-like species of Gulella.

Abstract

Gulella streptostelopsis spec. nov. is described from a series of localities of mainly between 1000 and 1500 m a.s.l. in Malawi south of about 11°S. The minute, almost smooth, shell (length 2.0-2.4 mm) resembles that of the genus Streptostele (hence the name), but is characterized by three-fold apertural dentition and just under six whorls. This taxon may represent a new genus; pending studies on the anatomy no new generic name is proposed.
