Body entirely black; antennal scape and funicle, and tarsomeres reddish brown.</p><p>Head (Fig. 7 C – E). Forehead flat, slightly narrower than rostrum base width; eyes elongate-oval, distinctly separated ventrally; rostrum elongate (Rl / Rw 5.16), longer than pronotum (Rl / Pl 1.10), evenly curved in lateral view, from base to apical 1 / 6 with short pubescence, apex with dense punctures; antennae inserted at apical 1 / 3 of rostrum; scape long (l / w4.75), not reaching eyes, gradually widening from base to apex, apical 1 / 3 markedly widened; funicular segments 1 and 2 elongate, segment 2 funnel-shaped, segments 4–6 transverse; club subobconical (l / w1.66).</p><p>Pronotum (Fig. 7 F). Longer than wide (Pl / Pw 1.07), widest at middle, apical 1 / 8 distinctly constricted, sides rounded; disc slightly convex in lateral view, densely covered with coarse punctures, punctures sparser on disc than laterally; dense, short pubescence forming median longitudinal pilose pustule; postocular lobes weak.</p><p>Scutellum. Small, subtriangular.</p><p>Elytra. Longer than wide (El / Ew 1.27), widest at basal 1 / 4, apical 1 / 6 distinctly constricted, sides rounded; disc nearly flat in lateral view; interstriae convex, subequal in width, with dense short pubescence, interstriae 1–8 bearing interrupted longitudinal pilose pustules, pustule width subequal to interstrial width; striae deep, punctures large, bearing dense, short pubescence; distance between punctures exceeding puncture diameter.</p><p>Abdomen (Fig. 7 G). Abdominal ventrites densely covered with coarse punctures; ventrite 2 with anterior margin slightly convex at middle, posterior margins of ventrites 2–4 rectilinear; ventrite 2 0.8 times length of ventrite 1, ventrite 3 slightly longer than ventrite 4, ventrite 5 2.0 times as wide as long.</p><p>Legs. Densely covered with short pubescence; femora and tibiae with punctures; procoxae subconical, contiguous; profemur more robust than mesofemur and metafemur, femora unarmed; profemur 3.3 times as long as wide; tibiae bearing single long uncus; protibia 6.2 times as long as wide; tarsi long, tarsomeres 1–3 obconical, ventrally with setae, onychium elongate; claws free, divergent; protarsomere 1 1.8 times as long as wide, tarsomere 2 1.3 times, tarsomere 3 1.4 times, onychium 4.3 times.</p><p>Male genitalia (Fig. 7 H – K). Pedon 0.2 times length of temones, curved in lateral view, sides curved, base symmetrical, apex broad and not narrowed; temones slender, slightly curved; manubrium of tegmen very robust, elongate, apex curved, approximately 3.0 times as wide as temones; spiculum gastrale robust, evenly curved; basal plate bifurcate, basal arms opposed, upper part of each basal arm approximately triangular, length subequal to width, apices with rounded angles.</p><p>Female sternite 8 and genitalia (Fig. 8 G – I). Sternite 8 with apodeme 0.8 times length of lamina; lamina bifurcate at base, sides curved, apex with sparse setae; gonocoxites cylindrical, apices with dense setae; styli short, cylindrical, width approximately 1 / 4 width of gonocoxite apices, apices with short setae; spermatheca with curved, apically rounded cornu; corpus robust; ramus and collum weakly developed.</p><p>Variation.</p><p>Male holotype. Measurements (in mm): Bl: 4.20. Rl: 1.65, Rw: 0.32. Pl: 1.50, Pw: 1.40. El: 2.42, Ew (Bw): 1.90.</p><p>Female paratype. Measurements (in mm): Bl: 4.40. Rl: 1.60, Rw: 0.35. Pl: 1.51, Pw: 1.45. El: 2.61, Ew (Bw): 1.98. Illustrations of a female are provided (Fig. 8 A – I).</p><p>Female rostrum smooth and shiny from middle to apex, while male rostrum smooth only at apex; female antennae inserted at middle of rostrum, whereas male antennae inserted at apical 1 / 3.</p><p>Distribution.</p><p>Known only from the type locality in Xizang, China (Fig. 9).</p><p>Etymology.</p><p>The specific name is derived from the Latin word pilosus (hairy), referring to the dense pubescence on the pronotum, particularly the distinct longitudinal tuft of pubescence medially.
