description: Colposcenia orientalis (Klimaszewski)   
(Figs. 1, 6–11)  
 Material examined. Iran: 14 ♂, 16 ♀, Kerman, Golzar, N 29°22’40”, E 57°01’34”, 6.ix.2016, Tamarix spp., M. Lashkari leg. (KGUT, HMIM, NHMB).   
 Description. Adult. Colour. Body dirty yellow to orange. Antennae dirty yellow with the three apical segments entirely dark brown. Genal processes dirty yellow, dark brown to black apically and ventrally. Eyes grey, ocelli red with a narrow surrounding orange band. Pronotum dirty yellow with four light brown spots. Mesopraescutum dirty yellow with two longitudinal light brown stripes. Mesoscutum dirty yellow with six longitudinal light brown stripes. Legs generally dirty yellow, but both tarsal segments of front legs dark brown, apical spurs on metatibia and metabasitarsus black. Forewing (Fig. 1) transparent with light brown veins and covered in many small light brown dots forming relatively round patches along wing margin and in basal part of cells r 1, r 2 and m 2, as well as two patches in cu 2. Hindwing hyaline. Terminalia dirty yellow; tip of paramere with a narrow black band; aedeagus dark; tip of female proctiger and subgenital plate brown.   
 Structure. Head slightly narrower than thorax; vertex 0.6–0.7 times as long as broad; genal processes short, apically rounded with short fine setae. Antenna 10-segmented, 1.5 times head width. Third antennal segment about 2.5 times as long as the second. Metatibia 0.7 times as long as head width, with seven sclerotised apical spurs in nearly similar distance. Metabasitarsus with two lateral sclerotised spurs. Forewing (Fig. 1) membranous, elongate oval, slightly widening and rounded apically, 2.3–2.7 times as long as broad, 3.4–3.7 times as long as head width; pterostigma short and narrow, about one third length of cell r 1. Hindwing shorter than forewing.   
Terminalia as in Figs. 6–11. Male proctiger with long, subparallel posterior lobes narrowing to apex, slightly curved medio-dorsally; posterior lobes longer than subgenital plate, bearing short setae in apical two-thirds but not in the basal third. Male subgenital plate with relatively straight dorsal margin in the middle, rounded in basal and apical quarters, with several sparse short setae latero-ventrally and postero-ventrally (Fig. 6). Paramere, in lateral view, short, lamellar, weakly produced antero-apically; bearing a few short setae postero-laterally and apically; inner surface with one sclerotised subapical process anteriorly and a lobe which is bent down, between these several short and thick setae, and below these setae, dense peg-like setae arranged in transverse rows, below of them a membranous conical process which is about as long as subapical anterior process (Figs. 7–8). Distal segment of aedeagus with a membranous lobe at base of apical dilatation dorsally (Fig. 9). Female proctiger, in lateral view, with dorsal margin distinctly convex, abruptly narrowing to apex in apical third, apex slightly swollen; proctiger 0.9–1.0 times as long as head width, 4.0–4.1 times as long as circumanal ring, 1.4–1.5 times as long as subgenital plate; basal half of proctiger without setae except for those surrounding the circumanal ring, dorso-apical half sparsely covered with long fine setae, and the narrowed apical portion covered densely with conical peg-like setae and several short setae. Circumanal ring small, composed of two rows of pores. Female subgenital plate, in lateral view, convex ventrally, subacute apically; lacking setae in basal half, covered sparsely with long fine setae dorso-ventrally and short setae dorso-laterally (Fig. 10). Dorsal and ventral valvulae smooth, without any teeth (Fig. 11).  
Measurements (in mm; 5 ♂, 5 ♀). Head width 0.48–0.52; antenna length 0.36–0.40; forewing length 1.76–1.94; male proctiger length 0.43–0.46; paramere length 0.20–0.22; length of distal segment of aedeagus 0.18–0.20; female proctiger length 0.57–0.61.  
 Distribution. Afghanistan, Armenia, Azerbaijan, Georgia, Iraq, Kazakhstan, Palestine, Russia (European part), Tajikistan, Turkmenia and Uzbekistan (Gegechkori & Loginova 1990; Malenovský et al. 2012; Spodek et al. 2017); new for Iran.   
 Host plants. Tamarix spp. (Tamaricaceae).   
 Comments. Сolposcenia orientalis, recorded here for the first time from Iran, was originally described from Iraq based on a single female (Klimaszewski, 1970). Subsequently, it was reported from Transcaucasia and Central Asia by Loginova (1974) who provided a redescription and illustrations of the terminalia. The inner surface of the paramere is not correctly depicted in her figure (Loginova 1974: 159, Fig. 75). To avoid future confusions, we provide figures and a redescription of this species.   
 Сolposcenia orientalis resembles С. tamaricis (Puton) and С. traciana (Klimaszewski) in the absence of dark spots on the apices of the veins along the apical forewing margin and the long posterior lobes on the male proctiger. It differs from both in the presence of two transverse rows of dense peg-like setae on the inner surface of the paramere and the dorsal outline of the female proctiger which is broadly convex in the middle, rather than narrowly convex in apical third as in С. tamaricis or almost straight as in С. traciana.
