Sergeya bunsoensis sp. nov.

( Figs 8 View FIGURES 1–10 , 32 View FIGURES 27–34 )

Type material. Holotype ♂, Ghana, Bunso , Bunso Arboretum, 21.xi.2011, LF, leg. W. Mey (gen. slide 553/23, O. Bidzilya) ( MfN).

Diagnosis. The species is characteristic by having distinct brown spot in middle of dorsal margin of forewings. The most similar species to S. bunsoensis sp. nov. is S. malawica sp. nov. These two species could be diagnosed as bellow: in S. bunsoensis sp. nov. brown scales above eyes are absent; thorax and tegulae are uniformly yellowish-brown (in S. malawica sp. nov. brown scales above eyes are present; thorax and tegulae distinctly mottled with brown). The male genitalia of S. bunsoensis sp. nov. resemble those of S. chuii sp. nov. (both species have slender vinculum with deep reverse V-shaped anterior emargination). However, S. bunsoensis sp. nov. has broad uncus, straight distal process of glandiductor, and apex of phallus with large triangular projection (in S. chuii sp. nov. uncus is narrow, distal process of glandiductor is curved, and apex of phallus with small triangular projection).

Description ( Fig. 8 View FIGURES 1–10 ). Wingspan 7.9 mm. Head yellowish-white, frons pale; labial palpus recurved, segment 2 brown mottled with yellowish-white and with white apex; segment 3 brown with white basal and apical rings; antennal scape yellowish-white, narrowly ringed with brown, flagellum light brown alternating with yellowish-white in basal half, in distal half 4 white flagellomeres followed by 3 brown, and then 1–2 white alternating with 3–4 brown, terminal 1–2 flagellomeres white; thorax and tegulae yellowish-brown; forewing yellowish-brown, costal margin brown, diffuse brown spot just after 1/2 length of costal margin, dorsal margin with brown spot on 1/2 length and with tornal spot on 3/4 length, apex yellow spotted with brown; fringe yellow on apex and light grey on dorsal margin; hindwing and fringe light grey.

Male genitalia ( Fig. 32 View FIGURES 27–34 ). Uncus moderately broad, weakly narrowed apically, densely covered with modified feather-like scales, twice longer than tegumen and same width at base as tegumen, extending to 1/2 length of cucullus; tegumen sub-rhomboid, broader than long; cucullus elongate, gradually broadened distally, apex rounded, densely covered in distal 2/3 with feather-like scales; glandiductor basally weakly swollen, then slightly narrowed, distal process as long as basal part of glandiductor, slender, straight, extending to 1/2–2/3 of cucullus; juxta lobes short, narrow; vinculum slender, with deep reverse V-shaped anterior emargination; saccus reduced; phallic tube elongate, straight, basal projection about 1/5 length of phallic tube, slender, apex with large lateral triangular projection.

Female genitalia. Unknown.

Biology. Host plant unknown. The holotype has been collected in late November.

Distribution. Ghana.

Etymology. The species name derives from Bunso town in Ghana, the type locality of this new species.
