Ustjuzhanin et Kovtunovich, sp.n.

Figs 1–2 .

TYPE MATERIAL: Holotype, ♂, ( BMNH gen.pr. 22799), [ Maluku Islands], Batian, Doherty, 1892. No. Walsingham Collection. B.M. 1910–427.

DESCRIPTION. External characters. Forehead covered with tightly clinging light-brown scales. Labial palpi straight, apically sharp, slightly shorter than longitudinal eye diameter. Antennae thin, yellowish-brown. Thorax and tegulae light-brown. Wingspan 17 mm. Fore wings light-yellow, lobes deeply split. Distinct dark spot at cleft base. Three small dark brown points along costa of first lobe distally. Dark strokes and points on second lobe apically. Fringe inside cleft white, only distally with small portion of brownish hairs. Fringe along outer edge of second lobe also white, with two portions of brown hairs medially and distally. Hind wings unicolorous, light-yellow, two small dark points only on second lobe apically. Fringe on hind wings white. Hind legs light-brown.

Male genitalia. Valves asymmetric, narrow, slightly widened in middle part, narrowing distally. Straight harpe on left valve, reaching middle of valve length, apically sharp, distally with small process. Long harpe on right valve, slightly wavy, basally with small claw-like process. Saccus horseshoe-shaped with oval cut. Anellus arms long, right arm noticeably wider than left. Uncus thin, smoothly curved medially, sharp apically. Aedeagus short, almost straight, twice shorter than valve, narrowing distally.

Female genitalia. Unknown.

DIFFERENTIAL DIAGNOSIS. In the male genitalia, in the shape of the valves and saccus, and the harpe on the right valve, the new species is similar to Pterophorus ceylonicus Ustjuzhanin et Kovtunovich, 2015 , but differs by the left harpe structure: in P. ceylonicus it is forked and significantly shorter than in the new species. Besides, the new species has a claw-like process on the right valve basally.

ETYMOLOGY. The species is named after the prominent collector, traveler and zoologist William Doherty (1857– 1901), who collected the new species.
