Perissomastix (Perissomastix) jemenitica sp. n.

Holotype: , “ Yemen, Hudaydah , Bajil, 19.iii.1992, [leg.] R. Linnavuori;”“Gen.präp. [genitalia slide] Gaedike Nr. 5972;” “ Holotypus , Perissomastix jemenitica sp. n., det. R. Gaedike 2013;” FNMH.

Derivatio nominis: Named after the country in which the holotype was collected.

Diagnosis ( Fig. 14 ): Wingspan ca. 15 mm (specimen not spread); head brush dark brown; antennae and labial palpi light clay brown; thorax, tegulae and forewings light clay brown too, forewings without any pattern; hindwings paler than forewings.

Male genitalia ( Figs 50-51 ): Uncus with two long lobi, basally narrowest, broader to truncated, medially lightly impressed apex, costal edge pointed, directed upwards, ventral edge rounded; first half of costal edge concave, second half straight, ventral edge before rounded apex curved; Valvae lanceolate, costal edge straight, ventral edge curved, apex pointed; phallus U-shaped, dorsal branch with clearly defined pointed tip, hook-shaped directed upwards, ventral branch with rounded apex.

Female genitalia: Unknown.

Remarks: Superficially not distinguishable from the other members of the subgenus, differences are only seen in the genitalia structures. Shape of the lobi of uncus (truncated, medially impressed apex) and the hook-shaped pointed tip of phallus differ from the other members of the subgenus (see PETERSEN, 1988; GAEDIKE, 2009).
