Diagnosis. This new species is externally resembling S. chuii sp. nov. and S. bunsoensis sp. nov. These three species differ from other Sergeya species by forewing which has costal margin concoloured to ground colour of the forewing (in other species of the genus forewing is suffused with brown). Male genitalia of S. hackeri sp. nov. are most similar to those of S. olei sp. nov., but in latter species ventral margin of cucullus is widened in basal half and bears setae (straight and does not bear setae in S. hackeri sp. nov.). The female genitalia of S. hackeri sp. nov. are similar to those of S. olei sp. nov. in having anterior margin of sternum VIII bent anteriorly. However, in the latter species ostium bears lateral tooth, antrum does not have lateral hump-shaped lobes, and signa gathered in г-shaped rather than ovate band in S. hackeri sp. nov..
Description ( Figs 4, 5 View FIGURES 1–10 ). Wingspan 7.1 mm. Head yellowish-brown, frons pale; labial palpus recurved, segment 2 brown mottled with yellow, its apex, inner and upper surface yellow; segment 3 brown with white basal and apical rings; antennal scape yellowish-brown mixed with dark brown; flagellum in basal half brown ringed with yellow, distal half with alternating 2–3 dark brown and 1–2 pale segments, terminal 1–2 flagellomeres white; thorax and tegulae yellowish-brown; forewing yellowish-brown, costal margin sparsely mottled with brown, diffuse brown spot on 2/3 under costal margin, apex with brown scales tipped with white, tornal brown spot with dark point inside on 3/4 of dorsal margin, fringe grey; hindwing and fringe light grey.
Male genitalia ( Fig. 29 View FIGURES 27–34 ). Uncus slender, elongate, gradually narrowed towards pointed apex, densely covered with modified feather-like scales and strong setae, about twice longer than and 1/2 width of tegumen; extending to 3/4 length of cucullus; tegumen rounded, anterior margin weakly produced anteriorly; ventral margin of cucullus straight, dorsal margin narrowed in distal 1/3, densely covered with hair-like scales, apex rounded; glandiductor inflated at base, distal process slender, extending about 2/3 length of cucullus; juxta elongate, weakly narrowed apically; vinculum slightly broad; saccus narrow, triangular, extending to top of pedunculus; phallic tube straight, weakly narrowed towards pointed apex, with two small lateral subapical teeth.
Female genitalia ( Fig. 42 View FIGURES 42–46 ). Papillae anales narrow, ovate, sparsely covered with short hairs; apophyses posteriores straight, thin, about 2.5 times longer than apophyses anteriores; sternum VIII unmodified, almost as long as broad, gently narrowed posteriorly, anterior margin weakly bent; apophyses anteriores straight, about same long as sternum VIII; ostium U-shaped; ductus slender, antrum funnel-shaped, weakly broadened posteriorly, with short lateral hump-shaped lobes in middle; corpus bursae egg-shaped, covered with dense lateral patch of needle-shaped sclerites in posterior part, numerous needle-shaped signa gathered in ring-shaped band extending from bottom to 3/4 length of corpus bursae.
Biology. Host plant unknown. Adults have been collected in November–December up to altitude of 1900 m.
Distribution. Yemen.
Etymology. The species is named in honor of Hermann Hacker, who collected the type series of this new species. Hermann Hacker is a well-known lepidopterist, who specialized mainly on the family Noctuidae .
