Angelopteromyia korneyevi Mohamadzade Namin, sp. n. from Iran is described and figured. The new species is similar to other species of Angelopteromyia in having abdominal spiracles 5 of females not approximated medially, as well as clypeus extended postero-ventrally, antenna shorter than face, and R1 and R4+5 setulose on dorsal side. It differs from other species of Angelopteromyia by having mostly brown wing with 3 hyaline crossbands and a few hyaline spots, and dark brownish basal and costal cells without hyaline spots.
Diptera, Platystomatidae, Iran, new species
The signal flies (Platystomatidae) are small to large-sized flies (3.5–20 mm) often with grayish microtrichose or bright and metallic blue or green body. Wings are usually strongly patterned and the cell bcu is closed by arcuate or straight vein at apex, without a posteroapical lobe (
Angelopteromyia Korneyev, 2001 is a genus of the subfamily Platystomatinae with 3 described species occurring in Central Asia (Angelopteromyia alf Korneyev, 2001, Angelopteromyia chvalai Korneyev, 2001 and Angelopteromyia merzi Korneyev, 2001). According to
While studying the tephritoid flies fauna in West Azerbaijan Province (Iran), a previously undescribed species of Angelopteromyia was collected by the first author. The new species is described and figured below.

The species is named for Dr. Valery A. Korneyev (I. I. Schmalhausen Institute of Zoology, Ukraine), who has made a valuable contribution to the study of Palaearctic Platystomatidae.
The new species is similar to other species of Angelopteromyia sharing most of generic characters, and first of all, abdominal spiracles 5 of females not approximated medially. Angelopteromyia korneyevi sp. n. differs from other species of Angelopteromyia in having entirely different wing pattern: dark brownish basal and costal cells without hyaline spots (in Angelopteromyia alf, Angelopteromyia chvalai and Angelopteromyia merzi, basal cells of wing reticulated with numerous hyaline spots). In addition, face in Angelopteromyia korneyevi sp. n. is completely shining black (only ventral half of face is shining black in Angelopteromyia merzi and half of face at least in the middle is densely microtrichose in Angelopteromyia alf and Angelopteromyia chvalai ventrally). Furthermore, the proctiger in Angelopteromyia korneyevi sp. n. is triangular in profile (apical part of proctiger is rounded in Angelopteromyia alf and Angelopteromyia chvalai). Acrophallic tubes in Angelopteromyia korneyevi sp. n. are equal in diameter and length (unequal (one thick and one thin) in Angelopteromyia merzi, and apically with cup-like extensions each in Angelopteromyia alf).
