Abstract A new oonopid genus endemic to Madagascar, Malagiella, is proposed and its 10 constituent species newly described and illustrated: M. ambalavo (♀), M. andringitra (♂♀), M. fisheri (♂♀), M. goodmani (♀), M. nikina (♀), M. ranavalona (♀), M. ranomafana (♂♀), M. toliara (♂♀), M. valterova (♂♀), and M. vohiparara (♂♀). Malagiella is most similar to the Asian genus Camptoscaphiella in both somatic and genitalic features, but differs in some important characters. Unlike Camptoscaphiella, the Malagiella male has a palpal bulb completely fused with the tarsus and a sternum bearing stiff bristles; the female has a round copulatory opening and bifid 4th claws. The species may be recognized by the genitalia. Male palpi are fairly uniform, but differ in segment proportion and details of the embolus complex, which consists of a broad dorsal embolus connected to a laminar ventral prong. Female genitalia are more variable, especially in the curvature of the receptaculum, which spans the range from nearly straig...
