Type material ( SNUC). Holotype: CHINA: 3, labeled ‘ China: Hainan Prov. / Ledong County / Jianfengling N. R. / 19.v.2011, alt. 1,000 m / Wen-Xuan BI leg.’; Paratype: CHINA: Ƥ, same label data as holotype, except ‘Jianfengling N. R. / core area No. V, 978 m / 3.xii.2009 / 18.73236° N / 108.87023° E / Mei-Ying Lin leg.’.

Diagnosis. Head triangular; vertex convex medially, U-shaped sulcus connecting well-defined foveae; postocular margins expanded laterally to form thick triangular tubercles; triangular pronotum broadly and deeply incised at level of lateral antebasal foveae; elytra barely constricted at base, with two large basal foveae; tergite IV about twice length of V.

Description. Male. BL 2.39. Body ( Fig. 2 View FIGURE 1 – 2 ) reddish brown, maxillary palpi and tarsi lighter; head, pronotum and elytra covered with dense setae, microtuberculate where setae arise. Head ( Fig. 12 View FIGURE 12 – 18 ) much wider than long, HL 0.36, HW 0.64; vertex with tuft of setae anterior to transverse arched median carina, vertexal foveae connected by U-shaped sulcus, sulcus broken at anterior margin; eyes well-developed, each composed of about 65 facets; antennomeres II–VIII ( Fig. 13 View FIGURE 12 – 18 ) of similar width, VIII–X distinctly transverse; clubs formed by enlarged antennomeres IX–XI. Pronotum much wider than long, PL 0.50, PW 0.83; with distinct longitudinal median and lateral sulci;with discal carinae at middle; lateral and antebasal spines large. Elytra wider than long, EL 0.76, EW 0.98; barely constricted at basal half. Metaventrite concave medially. Legs with thick femora; mesotibiae ( Fig. 14 View FIGURE 12 – 18 ) with tiny membranous apical projections; metatrochanters lack projection at ventral margin. Abdomen wider than long, AL 0.77, AW 0.89; tergites IV–VI with thick triangular lateral ridges; tergite VI ( Fig. 15 View FIGURE 12 – 18 ) with short discal carinae close, reaching one-fifth tergal length; tergite VII with small lateral protuberances. Sternite IV twice length of V at midline, with inner pair of basolateral foveae close to mediobasal foveae; sternites V–VII lacking foveae. Aedeagus ( Figs. 16–18 View FIGURE 12 – 18 ) well-sclerotized, length 0.33; basal bulb with large foramen, elongate median lobe sharpened apically.

Female. Similar to male in general. Measurements: BL 2.39, HL 0.36, HW 0.63, PL 0.49, PW 0.82, EL 0.74, EW 0.97, AL 0.80, AW 0.92. Vertex lacking transverse carina and tufted setae. Each eye composed of about 60 facets. Mesotibiae lacking apical tubercle.
