Heterostasis hackeri sp. n.

Holotype: , “ Yemen, 3.xi.1996, 15.11/43.32, Bajil Khamis Bani Sa ad, 750 m, leg. Hacker;” “Gen.präp.[genitalia slide] Gaedike Nr. 5560;” “ Holotypus , Heterostasis hackeri sp. n., det. R. Gaedike 2013;” ZMHB.

Derivatio nominis: Named after the collector, H. Hacker.

Diagnosis ( Fig. 7): Wingspan ca. 10 mm; head with creamy adpressed scales, antennae with same colouration, thick, scapus without pecten; labial palpi inside creamy, outside somewhat darker; thorax, tegulae and forewings shiny golden, without any pattern; hindwings shiny whitish.

Male genitalia ( Figs 36-38 ): Uncus with two pointed, bristled lobi, tegumen band-shaped, vinculum broad, with very long thin saccus; valvae with apodemes half of the length of phallus, apodemes nearly a half of the length of the entire valvae, inside the valvae an oblique, more strongly sclerotised, rod-shaped stripe with short thorns, costal edge concave, ventral edge in the first half parallel-sided, in the second half oblique to a rounded apex; phallus 2/3 of the length of uncus-tegumen-saccus complex, narrow, subapically with minute strongly sclerotised tooth.

Female genitalia: Unknown.

Remarks: Superficially distinguishable from the only other member of this genus ( H. extricata GOZMÁNY, 1965 ) in lacking the violet sheen. In the male genitalia the shape of valva (concave costal edge, parallel-sided and then oblique ventral edge) and the minute subapical tooth on phallus are characteristic for the species.

The species is the first representative of this genus in the Palaearctic.
