Material examined. CHINA, Xinjiang: 1♂, 1♀, Narat Mt. R., Bodon Valley, alp. meadows, h = 3000–3240 M, 43°01'09–47" N 83°10' 21–25"E, 25.07.2014, I. I. Kabak leg. / Rybinskiella bodoana Reitter, 1913; V. Zinchenko det. 2014 (ISEA).
Redescription. Male. EBL: 5.71 mm. Length of different body parts: HL: AL: PL: ELL = 0.93: 3.45: 1.23: 3.28 mm; width: HW: EW: PW: ELW = 1.05: 0.05: 1.66: 2.30 mm. Proportion of antennomeres from base to tip in µm (length × width): 227 × 106, 276 × 99, 355 × 105, 320 × 105, 277 × 105, 294 × 110, 336 × 132, 272 × 98, 271 × 132, 248 × 147, 368 × 135.
Habitus (Fig. 2E) elongate, evenly convex and sublustrous; well pigmented: mostly blackish brown; mouthparts, apical half of ultimate antennomere, and tarsi somewhat paler. Dorsum continually clothed with short, recumbent and sallow pubescence; elytra intermixed with long, erect hairs.
Head only slightly wider than long, HW/HL = 1.14. Surface covered with large, coarse and sparse punctures, separated about 2.0–3.0 times of their diameter, interspaces microreticulate. Clypeofrontal suture absent. Clypeus with gently emarginate anterior margin. Compound eye built from ca. 23–27 ommatidia, EW/HW = 0.05. Antennae (Fig. 12A) very long and slender, AL/HW = 3.27; all antennomeres distinctly longer than wide; length of 3rd/2nd = 1.29; 11th longest, narrowly pear-shape. Cervical sclerite with length/width = 2.11 in medial view (Fig. 4B).
Pronotum (Fig. 12B) subcampanulate and not much transverse, widest around middle, PW/PL = 1.35. Sides regularly narrowed forward from widest and gently constricted before hind corners. Hind corners rounded, protruding backward. Posterior margin slightly bisinuate, emarginate behind hind corners. Surface covered with fine punctures, interspaces transversely microreticulate, with distinct depression in each latero-basal area.
Elytra oval, incompletely fused with each other, widest at about basal 1/3, ELL/EW = 1.42. Sides regularly curved, evenly narrowing from widest to apex; apices rounded (Fig. 12G). Sutural striae absent. Surface covered with fine punctures, interspace with microtrichiae, aligning into transverse line. Metathoracic wings absent.
Prolegs slender, with basal three protarsomeres (Fig. 12C) strongly expanded: TW/BTW = 0.96. Protibiae (Fig. 12E) expanded inward in middle part, without visible outer spines. Profemora without tubercle on inner side. Mesotibiae very slightly curved, 1 st mesotarsomere (Fig. 7B) strongly expanded. Metatibiae very slightly curved.
Abdominal ventrite VIII (Fig. 12I) without middle indentation at anterior edge, while protruded posteriorly in middle of posterior edge. Genital segment (Fig. 12J) with spiculum gastrale slender and expanded at apex, and weakly expanded and deflexed dorso-ventrally (Fig. 12K); tergite IX rounded ventro-apically.
Aedeagus (Fig. 13A, B) with median lobe extremely long and slender (length/width = 10.78), slightly undulate, gradually narrowing apically from preapical part and terminated to a widely subrounded knob in dorsal view; parameres filiform, reached about apical 1/3 of median lobe, each with two apical setae; basal lama short; ventral operculum with two narrow lobes, each tapered towards apex and gently incurved. In lateral view, median lobe almost straight above curved base, thickened in middle part and flatted in apical part, apex slightly dorsally upturned (Fig. 13C). Internal sac (Fig. 13A–C) with a long acuminated tooth at apex, a cluster of phanerae in middle region, and a pair of teeth in basal region.
Female. Stouter and duller than male in general appearance (Fig. 2F), and also can be distinguished by the following characteristics: pro- & mesotarsi simply linear (Fig. 12D); protibiae (Fig. 12F) simply slender, furnished outer spines; elytral apices (Fig. 12H) distinctly acuminated; ventrite VII (Fig. 14A) almost simply emarginate at posterior edge; tergite VIII (Fig. 14B) truncate at posterior edge, with desclerotized area like the shape of an upside-down Chinese character “ ”; ventrite VIII (Fig. 14C) gently curved at posterior edge, with spiculum ventrale moderately wide; tergite IX (Fig. 14D) rounded at posterior edge, with numerous setae posteriorly; ventral sclerite (Fig. 14E) subtriangular, with deep Ω-shaped emargination at posterior edge, a few small sensillae located on posterior corners near emargination, small asperities present in posterior part; valvifer (Fig. 14D) with 1 lateral seta; coxite with 3 subapical setae, 1 basolateral seta and some much finer surface seta; stylus (Fig. 14D) long, cylindrical, with 1 long seta.
Distribution. China (Xinjiang), Kazakhstan, Kyrgyzstan.
