(Figs. 1A–C; 2A–J; 3A–D; 4A–D; 7A–B; 8A; 10; 11A)
Type material. HOLOTYPE, male, CHINA: Yunnan: Mt. Daweishan [], Pingbian County [], Honghe Prefecture [], 2000–2100m, 15.VII.2016, Zhi-Wei Dong leg. (CLQC).
Diagnosis. This species resembles H. tibetis, but can be easily distinguished from the latter by the following characters in the male: 1) body distinctly larger (13.1 mm, while 10.0– 10.1 mm in H. tibetis); 2) body shining black, only the apex of the antenna and the abdomen tip brownish (Figs. 2E, 3D), while in H. tibetis, head and pronotum shining black, antennae and elytra dark brown, legs brown; 3) pubescence black, while pubescence grey in H. tibetis; 4) hind angle of the pronotum obtuse at apex (Fig. 2F), while it is sharp in H. tibetis; 5) scutellum weakly covered with black pubescence, and widest at base (Fig. 2I), while it is covered with grey pubescence basally in H. tibetus and widest in basal third; 6) elytra wider with the sides slightly convex (Fig. 1A), whereas elytra narrower and the sides slightly concave in H. tibetis; 7) male genitalia also show differences in shape of the parameres (see Figs. 7A–C; 8A–B).
Description. Male (holotype). General: Body length 13.1mm, body width (elytra width) 3.9mm, elytra length 9.3mm, pronotum length 3.1mm, pronotum width 3.3mm, antenna length 3.8mm. Body shining, smooth, elongate, flat, dorsal surface sparsely covered with micro punctures and fine pubescence, ventral surface with relatively dense punctations and pubescence; color black except the follows parts: the apex of antennomere 11 and abdomen tip brownish yellow, tarsi slightly brownish yellow, claws yellow (Figs. 1A–C; 2E; 3D).
Head: Vertex trapezoid between eyes, with a shallow V-shaped depression, surface sparsely punctate, with sparse, short and black pubescence (Figs. 2A, D). Frontal region straight, frontal carina not strongly protruded, lateral sides ridged above antennae, smoothly declining medially (Fig. 2C). Eyes large, bulbous (Fig. 2A). Antennae (Fig. 2E) just reach the hind angles of pronotum, with yellowish pubescence, serrate from antennomere 4 to 10, and gradually narrowing from antennomere 4 on; scape long, generally equal to the length of antennomere 4, elongate oval shaped; pedicel shorter than other segments, coniform, slightly longer than wide; flagellum coniform, distinctly longer than wide; antennomeres 4 to 10 sub-triangular; antennomere 11 with apex trapezoid. Labrum (Fig. 2C) transverse, narrow, wrinkled and punctate, with some long yellowish pubescence medially.
Thorax: Prothorax slightly wider than long, thickest in median posterior slope. Pronotum (Fig. 2F) smooth, very sparsely punctate with micro punctures and small blackish pubescence only visible under magnification (Figs. 2G–H); disc arched, with a shallow depression in the middle posteriorly; lateral margins roundly convex, pronotal carinae almost straight in lateral view; hind angles long, distinctly divergent, apex thin and blunt. Hypomeron flat, slightly punctate and pubescent; prosternal sutures parallel medially, strongly curved anteriorly and posteriorly; prosternum with denser punctures and pubescence, two transverse wrinkled lines present distally, chin piece wrinkled, pubescent and punctate, with anterior margin convex, distinctly edged (Fig. 2B); prosternal process stick-like, rough, base slightly necked, apex narrowed, blunt (Fig. 3A).
Scutellum (Fig. 2I) flat, longer than wide, widest at anterior margin, sparsely punctate and pubescent; anterior margin slightly convex, lateral margins almost straight, narrowed from anterior to middle, posterior half slightly rounded. Mesoventral cavity tongue-shaped (Fig. 3B).
Elytra: Elongate, sides slightly convex, widest in posterior third; each with 8 deep striae, the interstriae clearly elevated, smooth, sparsely punctate and pubescent; each stria with a row of elongate punctures, the intervals between the punctures about 1–3 times of puncture length (Fig. 2J).
Legs: Slender, tarsi simple, segments 1 to 4 becoming sequentially shorter, segment 5 the longest, segment 4 the shortest. Metacoxal plate shaped as in Fig. 3C, widest at base, slightly curved and gradually narrowed towards lateral.
Abdomen: Sternite VII triangular, lateral portions distinctly depressed, tip with much larger punctures (Fig. 3D). Tergite VIII cordiform, densely pubescent, margin with additional long setae (Fig. 4A), tergite IX distinctly pubescent, hind lateral area with several long setae, apical portion triangularly concave (Fig. 4B), tergite X distinctly pubescent, apex round (Fig. 4B); sternite VIII transverse, hind lateral area with several short setae (Fig. 4C), sternite IX broadly elongate, apex obtusely angled, distal portion pubescent, with some small setae medially (Fig. 4D).
Genitalia: Penis wide, longer than parameres, apex short, strong narrowed and curved dorsally; paramere robust, each base with an incision in ventral view, the outer margin slightly convex, and then strong concave towards apex, apical portion triangular with hook-like angle, apex slightly pointed, phallobase with smoothly curved medially (Fig. 7A–B; 8A).
Female and larva. Unknown.
Distribution. China (South Yunnan).
Natural history. Remains unknown, the habitat photograph in Mt. Daweishan (2100m) is shown in Fig. 11A. It is possible that H. wennae sp. nov. as well as the other species of the genus inhabits forest biotopes.
Etymology. This new species is collected by the first author’s good friend Mr. Zhi-Wei Dong, and the species epithet is named in honor of Dong’s girlfriend Ms. Wen-Na Chen, for her support and love for Zhi-Wei Dong.
