Afrokana transmaculata , sp. nov.

( Figs 27–41 )

Description. Body length (including forewing): ♂ 5.0– 5.3 mm; ♀ 5.5–6.5 mm. Male ( Figs 27–29 ) predominantly pale ochraceous, with black median longitudinal stripe of variable breadth extended from apex of crown to tip of scutellum and continuous with dark marking covering most of clavus in male and transverse medial and apical bands on forewing, Female ( Fig. 36 ) with narrow median black stripe from head to apex of forewing, forewing with subapical black spot, pygofer with round black spot on dorsal surface, and pygofer extended beyond forewing apex.

Male pygofer ( Fig. 30 ) sclerotized with ca. 10 macrosetae along caudal margin; sclerotized ventral process likes a “paddle”. Subgenital plate with 9 macrosetae becoming shorter toward plate apex. Aedeagal shaft ( Figs 33, 34 ) cylindrical, posterobasal projection very short; in lateral view with apical section strongly curved posteroventrad with pair of short, weakly sclerotized apical processes extended posterodorsad, long unpaired tapered median process, and two pairs of shorter lateral processes, outer pair longer than inner pair, inner pair with few irregular medial teeth. Shaft in posteroventral view with lateral margins roundly expanded near basal third, with pair of long lateral processes arising just beyond midlength extended laterad then bent distad, apical processes curved mesad.

Material examined. Holotype ♂ (AMNH), Paratypes: 2♂♂ 6♀♀ ( AMNH, INHS), Africa Nigeria SE. St. Obudu Cattle Ranch , 16–18 VIII 1973, Linnavuori.

Remarks. This species is very similar to A. knorri but differs from the later in having the pale area on the forewing clavus open rather than being completely enclosed by black pigment, the lateral processes of the aedeagal shaft shorter and the median apical process much longer and the pygofer ventral process blunt rather than acute. Etymology. The specific epithet, a combination of “trans” and “maculata” refers to the transversal black stripe from the claval sulcus to the costal margin of the forewing.
