Polyhymno dumonti (Hartig, 1936) comb. nov.

Stigmatoptera dumonti Hartig, 1936 —Z. öst. EntVer. 21: 45, pl. 2, fig. 11.

Material examined. 1 ♂, Ein-Gedi, 17.ix.1968 (gen. slide 123/18, O. Bidzilya) ( TAU) .

Additional material. Paratype of Stigmatoptera dumonti ♂, Tunisie merid., Bou-Hedma, 8.vi.1929 ( Dumont ) ( SMNK) ; 1 ♂, Libya, Gharian, Wadi el Hira, 15.iv.1983 ( Seneca ) ; 1 ♀, same data but 27.v.1983 ( ZMUC) ; 1 ♀, Sudan, El Damer, Hudelba, 15.iii.1962 ( Remane ) | K. Sattler, B. M. (N.H.), 1974-570 ( NHMUK) .

Remarks. The genus Stigmatoptera Hartig, 1936 was established as monotypic for the new species S. dumonti collected in South Tunisia. Stigmatoptera dumonti agrees both externally ( Fig. 25 ) and in the male genitalia ( Fig. 26 ) with species of the genus Polyhymno Chambers, 1874 . Hence, we synonymize Stigmatoptera with the latter here: Stigmatoptera Hartig, 1936 syn. nov. of Polyhymno Chambers, 1874 .

Here we describe the male genitalia of S. dumonti for the first time.

Male genitalia. Uncus parallel-sided, twice as long as broad, posterior corners rounded; gnathos hook weakly curved, extending anteriorly to about 1/3 of tegumen; tegumen trapezoidal, weakly narrowed posteriorly, anterior margin with short rounded medial emargination; valva slightly shorter than tegumen, broad at base, distal portion straight, narrow, with strongly sclerotized ventral margin, apex rounded; sacculus short, hump-shaped; saccus about ¾ length of valva, gradually narrowed apically, constricted after half length, apex rounded; phallus strongly swollen at base, distal portion as long as basal portion, narrow, gradually tapering, with short narrow thorn before middle and on the apex, ductus ejaculatorius containg well developed lamina.

Remarks. Polyhymno dumonti externally resembles P. hostilis (Meyrick, 1918) , but the forewing is light brown rather than dark brown, white pattern along costal margin is broader, medial white area is narrower and white medial subtriangular streak before apex is absent. Two thorns in the phallus are characteristic for P. albifulvella Agassiz & Bidzilya, 2016 too, but the latter differs externally and the thorns are located in middle of the phallus.

Distribution. Tunisia, Israel (new record), Libya (new record), Sudan (new record).
