Oenopia shirkuhensis Zare Khormizi & Nedved sp. nov.

Type material.

Holotype. Male, Sorgan valley, Shirkooh mountain, Seikhalishah parish Dehbala village, Taft region, Yazd province, Iran, 31°37.50'N, 54°05.68'E, 2960 m a.s.l. 16. v. 2014. On Rosa canina . Lgt. Mehdi Zare Khormizi, Fig. 2 .

Paratypes. 5 males and 4 females in the same location and the same other data; 2 females at the beginning of the Najib valley, 31°37.60'N, 54°05.38'E, 3130 m a.s.l., 3 males and 2 females at the end of the Sorgan valley, 31°37.65'N, 54°05.35'E, 3155 m a.s.l., other data same. Figs 1 , 3 .

The holotype and one paratype of the new species will be deposited in the National Museum, Prague, Czechia. Five paratypes will be deposited at the University of South Bohemia, České Budějovice, Czechia. All specimens are in alcohol, but genitalia are on microscope glass in resin. Ten paratypes will be deposited in the collection of the first author, in Yazd, Iran. All are frozen.

Other material examined.

Iran, Kerman province, 5.5 km E of Sekonj village, Kukhbenan Mountains, at 30°00.00'N, 57°28.53'E, 2540 m a.s.l., 28. vi. 2014, lgt. Skrylnik Yu., 1 individual, determined based on the photograph made by Alexander Slutsky, Fig. 4 .

Etymology.

Adjective referring to the place of sampling, on the slopes of Shirkooh mountain (which means Lion mountain).

Diagnosis.

This species can be separated from its congeners by the colour pattern of elytra, which is orange-red with only one pair of rounded black spots lying slightly behind the half length of the elytra, either in the middle between suture and lateral margin (Fig. 2 ) or extended to the suture (Fig. 3 ), which bears a narrow black stripe. In the closest relative, the elytra has 16 spots (Figs 11 , 12 ). Abdominal ventrites are completely black (Fig. 6 ), while they have yellow margins in some congeners (Fig. 13 ). The two tips of penis guide are longer than wide and the parabolic shape between them, in outer view, is less than two times as wide as deep (Fig. 7 ). The tips in lateral view are inclined about 45° from the plane of main body (Fig. 8 ). Parameres are as long as the penis guide. In Oenopia conglobata , the tips of penis guide are shorter than wide, and the parabolic shape between the two tips are more than three times as wide as deep (Fig. 14 ), the tips are inclined about 80° from the plane of penis guide main body (Fig. 15 ), and the parameres are slightly shorter than the guide.

Description.

Body outline (Figs 1 - 4 ) broad oval, 1.35 × as long as wide, broadest behind middle of elytra. Dorsum convex and glabrous, except few hairs on head near eyes. Interocular distance 2.7 × as wide as eye. Pronotum with fine punctures. Elytra with large shallow punctures, separated by 1-2 diameters, interspaces between punctures smooth, shiny.

Head creamy white. Pronotum creamy white with seven black spots forming triple VVV, with two pairs of additional small spots lateral to large mediolateral spots. Elytra orange-red, shiny, with one pair of rounded black spots lying slightly behind the half length of elytra (see Table 1 ), in the middle between suture and lateral margin or eliptical, extended to the suture, which bears a narrow (quarter of width of scutellum) black stripe. Pronotum and elytra with explanate lateral margins transparent.

Prosternal intercoxal process (Fig. 5 ) narrow, with a pair of carinae extending over two-thirds of the prosternum length. Ventral side of thorax black, mesepimeron white with narrow black margins. Epipleuron 8 × narrower than body width. Scutellum 13 × narrower than body width (Fig. 1 ).

Abdomen with ventrites completely black. Abdominal postcoxal line (Fig. 6 ) bifurcated with the main branch parallel to the posterior margin of the ventrite 1, almost reaching lateral margin, secondary branch oblique (45°) separated from the main branch and from the coxal cavity.

Legs orange-brown, coxae black, fore coxae with white spot. Tarsal claws with basal tooth.

Male genitalia (Figs 7-10 ) with penis guide of tegmen in outer view (Fig. 7 ) bifurcated; penis guide slightly constricted before tips. Tips longer than wide, parabolic shape between tips less than two-times as wide as deep. Parameres as long as penis guide, clavate, truncate at apices with dense and long hairs. Penis guide in lateral view (Fig. 8 ) gradually narrowed. Tips in lateral view inclined at about 45° from main body plane. Penis (Fig. 9 ) with well-developed basal capsule with inner and outer arms subequal; penis apex strongly narrowed, then enlarged to wide soft tip (Fig. 10 ).

Body measurements: in mm; first value belongs to holotype, others to paratypes (smallest, largest, and most beautiful, i.e. female in Fig. 1 , of the paratypes); BL = 3.87, 3.76, 4.31, 4.05; BW = 2.89, 2.87, 3.35, 2.92; HW = 1.01, 0.96, 1.12, 1.03; PL = 0.88, 0.74, 0.88, 0.80; PW = 1.90, 1.92, 2.21, 2.08; EL = 2.79, 2.87, 3.21, 3.16.
