Diagnosis.

This species is very similar to Cynegetis syriaca in general appearance and male genitalia but it can be distinguished from the latter as follow: antennomere 7 subquadrate, scutellum black, most of black spots on elytra joined, forming wavy shaped bands, coxites bearing distinct styli and the characters of penis capsule and penis guide are distinctly different from the latter. In Cynegetis syriaca , antennomere 7 is distinctly elongate, scutellum yellow, black spots on the elytra are separated from each other and the coxites lack styli ( Fürsch 1986, Duverger 1983, WT, personal observations).

Description.

TL: 3.4-3.5 mm, TW: 2.7-2.9 mm, TH: 1.7-1.9 mm, TL/TW: 1.21-1.26; PL/PW: 0.44-0.45; EL/EW: 1.00-1.03; HW/TW: 0.38; PW/TW: 0.67.

Body short oval, dorsum strongly convex, densely pubescent (Fig. 3 a–c). Head yellowish brown, with small black spot at base. Pronotum yellowish brown, with three large black spots, the middle one longitudinal, expanded laterally at apical 1/4, the lateral pair irregularly oval. Scutellum black. Elytra yellowish brown, with three rounded black spots and three black wavy bands, arranged as Fig. 3 a–b. Underside yellowish brown, meso- and metaventrite black, epipleura and legs yellow.

Head with frontal punctures fine and inconspicuous, associated with scattered long setae; eyes of small size and moderately coarsely faceted. Maxillary lacinia moderately sclerotized, simple. Pronotal disk with fine and densely distributed punctures, slightly larger than those on head, 0.5-1.0 diameters apart. Elytral disk with punctures similar to those on pronotum. Prosternum and mesoventrite rough, with scattered short setae. Metaventrite broad with fine and inconspicuous punctures.

Male genitalia. Penis stout, strongly curved, apex slightly expanded, truncate with scattered short setae, basal capsule large (Fig. 3 m–n). Tegmen stout and symmetrical (Fig. 3 o–p). Penis guide in lateral view widest at base and narrowing to pointed apex, the basal 1/2 with a membrane part which accept stout penis (Fig. 3o). Parameres rather narrow and almost straight, distinctly shorter than penis guide (Fig. 3o). Penis guide in ventral view flattened, widest at basal 1/3, strongly narrowing to apex, apex blunt (Fig. 3p).

Female genitalia. Coxites oval, with distinct terminal styli (Fig. 3q). Spermatheca not studied.
