description: Dorcadion (Cribridorcadion) darakiensis Faizi & Nozari, sp. nov.
(Fig. 1: 1, 2)
Type material. Holotype, male: Iran, Kurdistan province, Divandareh County, Saral Area (35°36’46.86”N, 47°8’37.77”E), pitfall trap, 12.07.2016, Hamed Ghobari leg. Paratype, 2 females: Iran, Kurdistan province, Sarvabad County, village Daraki (35°19’3.46”N, 46°12’27.78”E), pitfall trap, 15.05.2017, Fardin Faizi leg. The type specimens were collected from pastures in mountain steppe belt using pitfall traps (Fig. 3).
Description of holotype. Body moderately elongate, length 13 mm, width 4.5 mm, dorsally with dark blackbrown integument, ventral surface, legs and antennae mainly brownish-black, antennomeres somewhere brownish, outer edges of antennomeres 1–4 reddish-brown. Tibiae apically darkened, nearly black.
Head partly covered with recumbent whitish pubescence forming longitudinal medial stripe and whitish spots at level of anterior margins of eyes; stripe with deep longitudinal furrow reaching anterior margin of pronotum; antennae rather thick, reaching beyond posterior third of elytra, first antennomer subequal in length compared to second and third antennomeres combined, third slightly longer than fourth, first and second antennomers and base of third antennomer with dense whitish pubescence, remaining antennomers with dense brown-yellowish pubescence basally and black pubescence apically.
Pronotum transverse, covered with dense pubescence hiding punctuation, with large lateral rather acuminate tubercles, pronotum on disk with recumbent dense black-brownish pubescence, with three white-yellowish longitudinal stripes—along middle and lateral margins (except tubercles), first one divided by distinct complete shallow longitudinal furrow. Scutellum triangular with obtuse angles, covered with whitish pubescence.
Elytra oblong oval, slightly vaulted, about 2 times longer than wide, humeral angles rounded, elytra apically separately rounded. Surface covered with dense black-brownish pubescence, each elytron with distinct longitudinal white-yellowish sutural and humeral stripes not reaching elytral apices. Very vague and indistinct velvet brownish stripes are external and internal dorsal stripes, and indistinct whitish spots are situated between dorsal elytral stripes near approximately posterior 1/4 of elytra. Humeral carinae black, reaching to posterior third of elytra. Ventral surface covered with dense whitish pubescence (Fig. 1).
Variability (sexual dimorphism). Paratypes, females (Fig. 1: 2) are bigger and wider (body length 15.0–16.0 mm, width 5.9-6.0 mm), humeral stripes of pronotum and elytra as well as longitudinal medial stripe on head, pronotum and along suture are more colorful, yellowish; most of head pubescence black, antennae shorter and thinner, six first antennomers black-brown; pronotum and elytra wider; on elytra humeral and sutural stripes narrower, each elytron between these stripes with dorsal velvet brownish stripes wider than in male—one rather wide and situated approximately equidistant between suture and lateral margins of elytra, and narrower one along sutural stripe; legs white pubescence fewer, pygidium apically with dense white-yellowish setae.
Differential diagnosis. The new species is similar to D. serouensis described from west Azerbaijan Province of Iran and known to us by its description (Kadlec 2006) (Fig. 1: 3). Dorcadion serouensis is bigger (in males 14.0– 17.5 mm, in females 16.1–18.6 mm), antennae in both sexes are somewhat ticker and shorter, antennae and legs are brown, apical portions of legs are not darkened. Short longitudinal spots on elytral disc between lateral and sutural stripes are more pronounced in both sexes of D. serouensis.
Distribution. Western Iran, Kurdistan Province.
Etymology. The specific epithet refers to Daraki village (Kurdistan Province) where some specimens from the type series were collected.
