Pronotum: Collar medially stramineous, sub-laterally brownish; pronotum mostly brown, disk of pronotum light brown, posterior margin stramineous with undulating, broken dark brown band. Scutellum: Mostly brownish, subapically with symmetrical brown marking, apex light brown. Hemelytra: Clavus, corium, embolium, and cuneus with more or less distinct light brown intermixed with dark brown mottling; two larger pale brown mottling marks on endocorium, apex of claval commissure dark brown; dark brown spot attached to costal fracture; cuneus apex dark brown and with two dark brown spots at medial margin; membrane with light brown mottling. Thoracic pleura and metathoracic scent gland (MTG): Propleuron mostly brownish red, proepisternum and proepimeron in part stramineous (Fig. 1C); mesopleuron mostly brownish red, mesepimeron marginally stramineous, metapleuron anteriorly stramineous, posteriorly brownish red, evaporative area and peritreme stramineous. Legs: Coxae stramineous, proximally with a reddish spot, meso- and metafemur proximally stramineous, dorsally and laterally with interrupted dark brown line; tibiae stramineous with dark brown spots, metatibia with three dark brown markings, one sub-proximally, one medial and another subdistally, apical two-thirds of metafemur with confluent dark brown mottling, tarsi stramineous to light brown. Abdomen: venter including pygophore brownish red.
Structure, vestiture and texture. Macropterous. Body elongate, dorsum densely covered with an intermix of semi-erect to decumbent black and white setae, eyes attached to collar, with tiny setae among ommatidia; gena barely visible in lateral view, antennal segment I with a few long bristle-like setae and densely covered with brownish short setae, antennal segments II–IV densely covered with whitish setae; labium surpassing middle of abdomen; collar distinct, calli obsolete, posterior margin of pronotum undulated, with four dark brown tubercles, pronotum trapeziform, humeral angles subacute; mesoscutum barely exposed in holotype (distinctly visible in paratypes); hemelytra longer than abdomen, apex and two dark spots at medial margin of cuneus with tufts of black setae, cell membrane distinct, ventral side of body and legs with whitish setae, tibial spine light brown.
Male genitalia: Pygophore covered with whitish hair-like setae, both sides of the basal margin of genital opening with small tooth-like tubercle (Fig. 3B). Left paramere bent, hook-shaped, corps of paramere expanded, dorsal surface and sensory lobe dentate (Figs 2 A-D), right paramere medially expanded (Figs 2 E–H), apophysis narrow, dorsally dentate. Limited variation in paramere shape was observed between holotype and paratype specimens, however because of shape of endosoma all specimens were considered conspecific. Endosoma as in figures 2I, 3A. Secondary gonopore large, reaching to the base of spiculum, spiculum with 25 teeth.

Measurements. Body length 5.17–5.41, width 1.67–1.88; lengths of antennal segments: I:1.03–1.07, II:2.24– 2.43, III:1.42–1.49, IV: 0.8 4–0.96; head width across eyes (in dorsal view) 0.89–0.96; interocular width 0.39–0.43, width of eye 0.25–0.26; ocular index 1.48–1.72; length of head (in lateral view) 0.45–0.71, height of head in lateral view 0.61–0.77, width of pronotum on posterior margin 1.46–1.58; medial length of pronotum (without collar) 0.61–0.68; pronotum 2.30–2.51× wider than long; width of anterior part of pronotum (collar) 0.59–0.66; length of collar 0.09–0.11; antennal segment I 1.09–1.17× head width; antennal segment II 2.39–2.56× head width and 1.42– 1.56× posterior width of pronotum; length of scutellum 0.64–0.66; width of scutellum at anterior margin 0.71– 0.77.
Differential diagnosis. The new species belongs to the amygdali -group species of the subgenus Compsocerocoris Reuter, 1876. It is morphologically close to Ph. (C.) amygdali Linnavuori, 1999 and Ph.(C.) mirzanus Linnavuori, 2006. However, it is recognized by the presence of two tubercles on both sides of genital chamber (without tubercles in Ph. (C.) amygdali; left side of genital opening with a round tubercle in Ph. (C.) mirzanus), the size of second antennal segment / head width (2.41–2.45 in Ph. (C.) amygdali; 2.2 in Ph. (C.) mirzanus) and the number of teeth of the spiculum (13 Ph. (C.) amygdali; 9 in Ph. (C.) mirzanus) (Table 1). Phytocoris (Compsocerocoris) darakiensis sp. nov. can be separated from all species in amygdali -group of the subgenus Compsocerocoris by the key hereafter.
Etymology. The species is named after Daraki from where the type materials were collected.
Collection circumstances. Collected by a bush net on Astragalus sp. and light trap.
Distribution. Iran (Kurdistan province).
