tween forceps with distal margin straight, paraproct of the 10th segment with a rounded subapical spur (as in fig. 3 in GILLIES 1994), gonopod 3-segmented with the third segment as long as broad, continuous brown line along the lateral margin of the abdomen. These specimens appear closely related to Pseudocloeon intone; mainly by sharing the peculiar spur on paraprocts (GILLIES 1994). This attribution remains tentative because it is based only on the imaginai stage. Distribution - Pseudocloeon mtone was previously only known from Tanzania (GILLIES 1994). It has not been collected again since the original description. Pseudopannota muganinani ELOUARD et GILLIES, 1990 Material examined - GHANA: Central Region, Tafo, Volta, 0°22'W, 6°14'N, 198 m, 3 0*0*, 10.05.1969 (G350), S. ENDRŐDY-YOUNGA. Diagnostic features - The male imagoes of Pseudopannota muganinani can be easily separated from other species of Pseudopannota WALTZ et MCCAFFERTY, 1987 by the peculiar turbinate eyes; they look mushroom-shaped with the upper face overlapping the base of the turbinate eyes as well as the upper portion of the compound eyes. The third segment of the gonopods is truncated (fig. 12 in ELOUARD et al. 1990) rather than rounded in other species of Pseudopannota (fig. 5 in ELOUARD et al. 1990; figs Id and 2d in ELOUARD & HIDEUX 1991). The male imago of P. muganinani is also quite similar to the one of Ophelmatostoma camerunense (ULMER, 1920). However, O. camerunense differs from all species of Pseudopannota by having the inner margin of the basal segment of the gonopods expanded apically, and from P. muganinani also by the shape and colour of the turbinate eyes (GILLIES etal. 1990). Distribution - This species is restricted to West Africa, where it possesses a wide distribution, but is less abundant than other species of Pseudopannota (ELOUARD et al. 1990). It was collected mainly in streams in the savannas as well as large rivers in the forest zone. This first report from Ghana extends the distribution of the species to the East. Baetidae Genus 1 (Figs 1-4) Material examined - GHANA: Northern Region, Banda-Nkwanta, Volta, 2°09'W, 8°22'N, 122 m, 1 cT, 1 ?, 27.10.1965 (G087); same locality, 1 $, 01.05.1965 (G020); 2 $$, 01.10.1965 (G088); 1 Ó*, 07.10.1965 (G089); Ashanti Region, Kumasi, Volta, 1°36'W, 6°43'N, 293 m, 1 Ó*.
