Identification. HUTCHINSON (1930a) (original description, figures); HUTCHINSON (1932a) (redescription, figures).

Habitat. In Socotra, the species was collected in medium--elevation zone, in a large pool with sparse littoral vegetation in a drying wadi ( Fig. 53 ). According to LINNAVUORI (1981), it lives in pools and rivers in the Sahel and Sudan savannahs. In Kenya, it was found in a permanent shaded pool with aquatic vegetation ( HYNES 1955). In Zimbabwe, it was collected in pans (small, temporary seasonal lakes) with rich littoral vegetation as well as in small pools ( WEIR 1966). LANSBURY (1961a) recorded it from a swampy marsh with shallow water in Namibia. It was collected at light in Namibia and Sudan ( POISSON 1957a, LINNAVUORI 1971).
