گزارش جدید یک جنس و گونه از زنبورهای خانوادهEncyrtidae (Hym.: Chalcidoidea) از ایران

Within the recently collected chalcidoid parasitic wasps (Hymenoptera: Chalcidoidea) from Tabriz vicinity, East-Azarbaijan province, an encyrtid wasp was found. Examination of collected specimens showed these belong to the genus Callipteroma Motschulsky that includes four species in the world. It was identified as Callipteroma sexquattata Motschulsky, 1863 (Hym.: Encyrtidae). This species is widely distributed in the Palaearctic, Afrotropical and Oriental regions, but is new record for Iranian fauna. Previously 159 species representing 48 genera species of this family has been reported from Iran, which including this species these reach 160 species and 49 genera. Based on available literatures this species is parasitoids of Pseudococcidae (Hemiptera), but we collected it via a Malaise trap. The specimens were deposited in the insect collection of the Department of Plant Protection, East-Azarbaijan Research Center for Agriculture and Natural Resources, Tabriz, Iran. The most important morphological characters of this genus are as follow: Scape in female cylindrical, pedicel shorter than first funicular segment, funicle six-segmented and all funicular segments longer than wide in male and female, club three-segmented, antenna in male with short, erect hairs; wing dark with small, hyaline spots; ovipositor sheath shorter. Callipteroma sexquattata is nearly allied C. testacea Moschulsky, but with following characters could be separated: Body dark-brown, legs testaceous to brown, scape testaceous to brown, pedicel concolorous or dark brown; flagellum dark brown; forewings mostly dark brown with six varaible pattern of hyaline aeas, but normally hyaline at base, two hyaline spots below submarginal vein one on anterior wing margin at apex of venation, and one opposite on posterior wing margin, one distad of this in disc of wing occasionally extendeing to posterior wing margin and apex narrowely hyaline; hind wing compeletly hyaline or with base and apex infuscate; propodeum steeply inclined and appearing short in dorsal view, medially the distance the anterior and posterior margins equal to not more than one-fifth length of scutellum. Male similar to female but infuscation of fore wing normally weaker and often with two or more of the hyaline spots confluent, especially those in the center of the wing; antenna with about 9-11 indistinct whorls of relatively short setae on each segment, the longest about 1.5-2 times as long as maximum diameter of segments.
