Range extensions of two streptaxids in Mozambique (Gastropoda, Pulmonata, Streptaxidae)

The streptaxid species Gulella perissodonta and Streptostele herma are recorded from northern Mozambique close to the border with Tanzania, a considerable range extension for the former and filling in a major geographical gap for the latter, which was also found in northern Tanzania, so far its northernmost occurrence. G. perissodonta also probably occurs in the eastern tip of Botswana, another range extension, this time westward.
