General description: See Oldroyd (1970) . Description of male genitalia ( Figs 4–8 : Holotype ): Genital capsule rotated clockwise through approx. 90° (degree and direction probably not significant – see transvaalensis ). Epandrium in dorsal view ( Fig. 5 ) slightly longer than wide (length: breadth ration = 1: 1.07), in lateral view ( Fig. 4 ) broad, with broadly rounded proximal and distal ends and slightly curved. Proctiger in dorsal view ( Fig. 5 ) clearly distally bilobed and projecting well beyond epandrial lobes. Hypandrium in ventral view tapering slightly to broadly curved distal end ( Fig. 6 ). Gonocoxite in lateral view ( Figs 4–7 ) with somewhat rectangular appearance, dorsal lobe robust (hidden from view in dry condition); gonostylus in lateral view ( Fig. 7 ) with rounded apex bearing a slightly backwardly-directed dorsal spine. Aedeagal base in ventral view ( Fig. 8 ) lacking distally directed projections. FIGURES 4–8 . Perasis carpenteri Oldroyd, 1970 . Holotype male terminalia. 4. Lateral. 5. Dorsal. 6.

Uganda : Bunyoro, v.1928 ( G. D. H. Carpenter ) ( BMNH ). Paratypes . Urundi : Kinanga, Ruzizi [River – 02°55’N 29°10’E ], 3♂ , 8Ψ, xi.1951 ( F. J. F r a n ç o i s ) (FJF).’ No illustrations were provided. MATERIAL STUDIED. UGANDA : 1♂ holotype , ‘Holo- / type’, ‘ Perasis / maura / Mcq’, ‘ Uganda / Bunyoro [Kingdom of – 01°40N 31°30’E ] / v.1928 / G.D.H. Carpenter’, ‘ Perasis / carpenteri Oldr. / det H. Oldroyd, 1964 / Holotype’ ( BMNH ). Condition of holotype : Moderate, generally dirty. Head greasy, silvery mystical setae gummed up. Antennae lacking postpedicels. Thorax badly cracked down centre of mesonotum, probably the result of a large accumulation of verdigris around the pin within the thoracic cavity. Left hind leg missing beyond trochanter. Distribution, phenology and biology. Known only from the East African type material collected at the type-locality in Uganda and one locality in Burundi . Collected in May and November. Biological data are not available. However, like transvaalensis (see below), this species may only be encountered in the vicinity of flowing water (Kinanga being on the eastern banks of the Ruzizi River between Zaïre and Burundi ).
