Gulella (Juventigulella) ngerezae spec. nov. (Gastropoda, Pulmonata, Streptaxidae), a new endemic land snail from the Ukaguru Mountains, Tanzania

A new species of land-snail (Streptaxidae: Gulella) from montane forest in the Ukaguru Mountains (Tanzania) is described and attributed to subgenus Juventigulella Tattersfield on shell characters. There are shell and radular resemblances to certain other Gulella species not in subgenus Juventigulella, emphasising the need for revisionary work. This is the second endemic snail described from the Ukagurus, a recognised area of endemism but one from which few land snails have been collected.
