Type material.

Holotype, female, 四川 峨边 1900公尺 木合 川 1960-VI-29 采集者 ：殷惠芬 [China: Sichuan, E’bian; 1900 m, 29.vi.1960, Huifen Yin, ex Schima superba ] (NMNH).

Diagnosis.

3.9 mm long (n = 1); 2.05 × as long as wide. This species is distinguished by the dense mesonotal mycangial tuft that extends laterally from the scutellum to striae 3; declivital posterolateral margin obliquely costate to interstriae 5; elytral disc with a weak transverse saddle-like depression; declivital summit with large incurved spine on interstriae 2, interstriae 3 with two additional unequally sized denticles ventrad to large spine; declivity weakly sulcate to interstriae 3; declivital strial punctures large each bearing a recumbent seta, interstriae minutely punctate, punctures uniseriate, setose, setae erect, hair-like; body moderately sized and abundantly covered with long erect hair-like setae; declivity shiny; and pronotal asperities small, coarse, densely spaced.

Description

(female). 3.9 mm long (n = 1); 2.05 × as long as wide. Body dark brown. Legs and antennae light brown. Head: epistoma entire, transverse, with a row of hair-like setae. Frons moderately impressed above epistoma then weakly convex to upper level of eyes, impunctate, median area of with a oval-shaped smooth, glabrous, strongly shiny area; lateral areas shagreened, coarsely rugose, setose; each ruga bearing a long, erect hair-like seta. Eyes shallowly emarginate just above antennal insertion, upper part smaller than lower part. Submentum large, distinctly triangular, slightly impressed. Antennal scape regularly thick, as long as club. Pedicel as wide as scape, shorter than funicle. Funicle 4-segmented, segment 1 as long as pedicel. Club longer than wide, obliquely truncate, type 1; segment 1 corneous, encircling anterior face; segment 2 narrow, concave, corneous on anterior face only; sutures absent on posterior face. Pronotum: 0.89 × as long as wide. In dorsal view rounded, type 1, sides convex, rounded anteriorly; anterior margin with a row of six large serrations. In lateral view type 3, short and tall, disc as long as anterior slope, summit at midpoint. Anterior slope with widely spaced, large coarse asperities, becoming lower and more strongly transverse towards summit. Disc subshiny, median area weakly rugose, lateral areas with dense, large, shallow punctures bearing moderate, erect hair-like setae, some longer hair-like setae at margins. Lateral margins obliquely costate. Base transverse, posterior angles broadly rounded. Mycangial tuft present along basal margin tuft broad, densely setose, laterally extending to elytral striae 3. Elytra: 1.0 × as long as wide, 1.13 × as long as pronotum. Scutellum narrow, large, linguiform, flush with elytra, flat, shiny. Elytral base transverse, edge oblique, humeral angles rounded, parallel-sided in basal 2/3, then narrowly rounded to apex; surface shiny. Disc with a weak medial transverse saddle-like depression, striae not impressed, with small, shallow punctures separated by 2-4 diameters of a puncture, setose, setae as long as a puncture, recumbent, hair-like; interstriae flat, punctate, punctures strongly confused, setose, setae 1.5 × width of interstriae 2, erect, hair-like, unarmed by granules. Declivity occupying approximately 1/2 elytra, evenly rounded, declivital face weakly sulcate to interstriae 3; striae not impressed, strial punctures somewhat larger and deeper than those of disc, and bearing setae as described for disc; interstriae sparsely minutely uniseriate punctate, setae 1-2 × width of interstriae 2, erect, hair-like, interstriae 2 narrower than interstriae 3 at midpoint of declivity, declivital summit with a large incurved spine on interstriae 2, interstriae 3 costate with two additional unequally sized denticles ventrad to large spine. Posterolateral margin costate to interstriae 5. Legs: procoxae contiguous; prosternal coxal piece short, inconspicuous. Protibiae distinctly triangular, broadest at apical 9/10; posterior face smooth; apical 1/2 of outer margin with seven large socketed denticles, their length longer than basal width. Meso- and metatibiae flattened; outer margins obliquely triangular with 11 and 14 small socketed denticles, respectively.
