Redescription. Female. Length, 0.90–1.01 mm. Body, in dorsal view, Fig. 33 . Head with frontovertex greenish from occipital margin to posterior ocelli, purple in ocellar area and up to facial impression; facial impression to mouth margin greenish or bluish-green. Antenna with radicle dark brown; scape white, upper margin dark brown, and with an indistinct pale brownish infuscation in distal half; pedicel dark brown with about apical third white; flagellum whitish yellow, each funicle segment and first segment of clava basally brown; distal two segments of clava yellowish brown. Mesosoma dark brown; pronotum, visible part, dark violet; mesoscutum completely greenish or bluish green; scutellum largely purple, with sides narrowly and posterior third greenish; tegula dark brown; mesopleuron violet. Wings hyaline; fore wing infuscate around marginal and postmarginal veins. Legs, including coxae, white to yellowish-white. Gaster from base to cercal plates yellow, from cercal plates to apex dark brown; third valvula dark brown.

Head, in dorsal view, with frontovertex width about one-fourth head width; ocellar triangle with apical angle very slightly acute; POL:OOL:OCL, 5:0.5:3; head, in frontal view, 1.16× as broad as high [on slide, 1.27× as broad as high, Fig. 34 ]; eye height 1.83× malar space; frontovertex with raised, polygonal reticulate sculpture, the cells small; facial region with fine, elongate reticulate sculpture; malar space with elongate reticulate sculpture, but in lower half polygonal reticulate sculpture; setae white; eye bare. Mandible with a short pointed tooth, a blunt middle tooth, and a broad truncation. Antenna ( Fig. 35 ) slender, elongate; pedicel plus flagellum slightly longer than head width; funicle segments all longer than broad; F1 slightly less than 2× as long as broad, and slightly shorter than F2; F2 onwards at least 2× as long as broad; clava at most as long as F4–F6 combined. Relative measurements (card): head dorsal width, 35; frontovertex width, 9; head frontal height, 30; eye height, 22; malar space, 12; pedicel plus flagellum length, 37.

Mesosoma. Mesoscutum with fine, polygonal reticulate sculpture; scutellum anteriorly with raised, reticulate sculpture, in medial third the cells slightly elongate, and laterally with lineolate-reticulate sculpture; posterior third very finely reticulate, but apex smooth ( Fig. 38 ); setae white; propodeum with silvery white setae distal to spiracle. Fore wing 2.22× as long as broad; an oblique bare area present below parastigma, indicated by an arrow in Fig. 37 ; marginal vein slightly longer than or subequal in length to, postmarginal vein, both combined shorter than stigmal vein ( Fig. 36 ). Mid tibia 3× as long as mid basitarsus; mid tibial spur 0.73× mid basitarsus length. Relative measurements (slide): Fore wing length (width), 100 (45); mid tibia length, 46; mid basitarsus length, 15; mid tibial spur length, 11.

Metasoma. Relative measurements (slide): TVII length, 30; ovipositor length, 41.5; third valvula length, 7. [Ovipositor 0.9× mid tibia length; third valvula 0.46× mid basitarsus length, and 0.63× mid tibial spur length.]

Male. Not yet collected in Iran.

Material examined. 7 ♀ (3 on slides, EH.1931, EH.1932, EH.1942): IRAN: [Semnan Province,] Mabad, Damghan, 5.viii.2015, Coll. MR Mehrnejad Acc. 1 and Ex. Eggs of Brachynema germarii on Pistacia vera . (1 ♀ in BMNH; 1 ♀ in NPC; 5 ♀ in ZDAMU).

Hosts. In Iran: Brachynema germarii (Kolenati) ( Hemiptera : Pentatomidae ) on Pistacia vera L. ( Anacardiaceae ). Recorded from Hemiptera ( Coreidae , Pentatomidae , Pyrrhocoridae , Reduviidae , Scutelleridae ) and Lepidoptera ( Lasiocampidae , Lymantriidae , Notodontidae , Papilionidae , Sphingidae ) ( Trjapitzin 1989; Huang & Noyes 1994; Japoshvili & Noyes 2006)

Distribution. Throughout the Palaearctic region; India, Pakistan.

Comments. This species is well-known and distributed widely in the Palaearctic region, and India and Pakistan. As it is recorded from Iran for the first time on pistachio stink bug, B. germarii , and is therefore redescribed and illustrated.
