Material examined.

GEORGIA • 1 ♂; Dedoplistksaro Mun., Vashlovani NP ; N 41.1194226 °, E 46.6097341 °; 460 m a. s. l.; leg: N. Bulbulashvili; 16 April 2022; JLGT .

Description.

Male genitalia. Tegumen long and triangular; uncus small, sclerotized, triangular peak-shaped. Socii oval with setae. Arms of gnathos long, thin, and fused by membrane; gnathos knob, triangular, and membranous. Valvae lanceolate, 6 times longer than wide; apex roundish, basal half of costal margin convex, apical half concave, dorsal margin 2 / 3 from base slightly concave, apical part 1 / 6 membranous, basal part 5 / 6 sclerotized; margin between membranous and sclerotized parts clear and roundish, dorsally membranous reach end of sacculus. Sacculus clearly separated from valvae, slender, 2 / 3 length of valvae; base roundish, gradually narrowing towards the outer end. Arms of transtilla relatively short, thin, and strongly sclerotized; transtilla knob not well visible, membranous. Lateral juxta triangular. Saccus well developed, nearly half as long as width, apex rounded, anterior margin strongly sclerotized, slightly concave, posterior margin of vinculum rounded. Aedeagus cylindrical, slightly longer than valvae, without cornutus. Vesica membranous, basal part large and roundish, distal part gladiate, without cornutus.

Remarks.

The species is known from Turkey, Azerbaijan, Afghanistan, Syria, Iraq, Israel, and Iran ( Schoorl 1990; Alipanah et al. 2021; Japaridze and Hulsbosch 2023). It is the first record of Dieida from Georgia. Host plant, eggs, and caterpillar are unknown.

It should be noted that the only specimen of D. ledereri , mentioned above, was preyed upon by a robber fly (Asillidae), which was caught and dropped the specimen on the ground. Unfortunately, the specimen later was damaged during the transportation, thus we don’t have the photograph of the undamaged specimen to fully express the natural colors. However, the undamaged specimen had bipectinate black antennae with 2 / 3 white on the anterior side, half the length of the forewing, and rami long and black. Head, tegula, thorax, and abdomen densely hirsute and black with a golden terminal part, golden-brown both dorsally and ventrally. Forewings semitranslucent; basal area white-ivory. Hindwings semitranslucent; white-ivory spots on submedian area and hind margin.
