description: Cleopomiarus danfengensis Jiang & Caldara n. sp.
Type locality. Jiefangcun Danfeng County, Shangluo (Shaanxi, China).
Type specimens. Holotype, male, CHINA: Shaanxi: Jiefangcun Danfeng County, Shangluo (33°51'N, 110°24'E, 1391 m), 13-VIII-2015, leg Menglei Zhang. Paratypes, same data as holotype (1F); CHINA: Shanxi: Qinshui Lishan Conservation Area Shunwangping (35°35′N; 111°57′E, 2250 m), 15-VII-2013, leg Lizhi Huo (1F).
Diagnosis. Body length 3.5–3.6 mm. Dorsal vestiture with dark brown and white scales intermixed; first elytral interstria covered with a fringe of white, long scales at apical declivity. Rostrum moderately long, in lateral view distinctly arcuate. Pronotum moderately transverse, with partly raised scales. Elytra subrectangular, moderately long, weakly curved at sides, widest at basal third, with subrecumbent to suberect scales. Mesofemora with a small obtuse tooth and metafemora with moderately distinct obtuse tooth; uncus of metatibiae in male pointed at apex.
Description (holotype). Length 3.5 mm. Body stout, integument black (Fig. 11–12). Rostrum (Fig. 30) 1.13 mm, moderately long (Rl/Rw 5.63; Rl/Pl 1.06), distinctly arcuate in lateral view, moderately tapered from antennal insertion to apex. Antennae dark brown, inserted near middle of rostrum at apex; funicle with segment 1 1/3 as long as scape, segment 2 shorter than segment 1, segments 3, 4 and 5 globose. Eyes flat. Pronotum moderately transverse (Pw/Pl 1.27–1.36), subconical, with rounded sides, widest in basal third, convex, with subrecumbent to suberect, dark brown and white intermixed, moderately long, seta-like scales; white scales more numerous at sides. Scutellum with short white scales. Elytra subrectangular, moderately long (El/Ew 1.30), moderately wider than pronotum (Ew/Pw 1.36), at base moderately directed forwards from interstria 5 to humeri, with somewhat rounded sides; interstriae covered with 3–4 irregular rows of subrecumbent to suberect, dark brown, seta-like scales, with white scales randomly distributed. First interstria covered with fringe of white, long, seta-like scales at apical declivity. Mesofemora with small obtuse tooth and metafemora with moderately distinct obtuse tooth (Fig. 51–54); uncus of metatibiae 0.1mm, in male pointed at apex (Fig. 39). Genitalia. Penis 1.00 mm, gradually narrowed from base to apex; endophallus at base with flagellum enlarged, and connected with sclerite straight and stick-shaped (Fig. 69).
Female paratypes. Length 3.5–3.6 mm (Fig. 13–14). Rostrum 1.12–1.25 mm, moderately long (Rl/Rw 5.60– 6.25; Rl/Pl 1.00–1.07), distinctly arcuate in lateral view, somewhat tapered from base to apex (Fig. 31). Pronotum less transverse than in holotype (Pw/Pl 1.28–1.31). Elytra shorter than in holotype (El/Ew 1.15–1.19), moderately wider than pronotum (Ew/Pw 1.36–1.38). Genitalia. Spermatheca 0.20 mm, slim, body distinctly bisinuate, not hook-shaped, weakly enlarged; collum distinctly narrowed in apical half, long and thin, slightly shorter than length of body; ramus short (Fig. 75). Spiculum ventrale 1.00 mm, with parallel arms (Fig. 80).
Etymology. The name of this species is an adjective referring to the site of collection.
Remarks. This species is distinguished from all other Palaearctic species by the comb of white scales at the apical declivity of interstria 1 and by the shape of the rostra especially in the female. It shares the pattern of the dorsal vestiture of dark brown and white scales intermixed with C. flavoscutellatus, in which however the scales of the scutellum are yellowish and not white. The tooth and the uncus of the metatibiae are similar to that of C. graminis, whereas the male genitalia are similar to those of C. distinctus. This apparent mountain species was collected on herbaceous plants on an open hillside and a semi-open mountain valley over 1000 m elevation. Distribution. Central China (Shaanxi Province and Shanxi Province).
