First record of Homotropus longiventris (Hym.: Ichneumonidae, Diplazontinae) from Iran

The subfamily Diplazontinae (Hym.: Ichneumonidae) has 340 described species to date (2, 5). A large scale sampling during 2010-2011 in the north of Iran resulted in reporting of 16 species of this subfamily from Iran (3) which of them two species belonged to the genus Homotropus Forster, 1869. Recently, two other species of the genus were reported from Kerman province (1, 4). Here, the fifth species of the genus, Homotropus longiventris, is reported for the first time from Iran. The second author confirmed the scientific name of this species. Specimen was deposited in the insect collection of College of Agriculture and Natural Resources of Darab, Shiraz University.Homotropus longiventris Thomson 1890:Material examined: IRAN, Mazandaran province, Noor county, (N= 36° 18′ E= 52° 07′, 1332m a.s.l.), 1♀, 11.July.2011, sweep netting.General Distribution: Belgium; Finland; Germany; Ireland; Lithuania; Mongolia; Netherlands; Norway; Poland; Romania; Russia; Sweden; Switzerland; United Kingdom (5) and Iran (new record)Morphological diagnostic characters: Homotropus longiventris can be identified from other species of the genus by the key and description provided by Klopfstein (2014) as following: antenna in females with 19 to 20 flagellomeres, apical flagellomeres with dorsal and ventral multiporous plate sensilla; clypeus weakly excised, with lobes somewhat ungulate at outer corners; yellow central face patch confluent with yellow clypeus; mesoscutum finely coriaceous, strongly punctuate, with anterolateral yellow marks; scutellum laterally and apically yellow; fore wing areolet closed, vein 3rs-m usually unpigmented; metasoma black, elongate and middle segments parallel-sided; first tergite short, without median dorsal carinae, with few longitudinal wrinkles, 1.0–1.3 times as long as wide; legs orange, fore and mid coxae yellow, hind coxa orange, femora yellow or orange, hind tibia white with apex, base and a subbasal spot dark, hind tarsus dark.
