Description. Male ( Figs 4 View FIGURES 1–4 , 8 View FIGURES 5–8 , 12 View FIGURES 9–12 ; n = 7): BL = 6.4–8.3 mm, BW = 2.5–3.2 mm.

Body dark brown, with brown pubescence mingled with light-brown pubescence in dominant part. Head intermixed with yellowish pubescence partly and surrounding eyes, with a pair of round small black pubescent spots on vertex between antennal tubercles. Pronotum with yellowish pubescence on lateral tubercles, with small spot of same pubescence on suture behind apex and before base, with a pair of transverse narrow bands of black pubescence on apical 1/3. Scutellum with yellowish pubescent margin. Each elytron with dark-brown vitta obliquely extended apically from humerus toward middle and from suture near middle toward apical 3/5 of lateral side, with large indistinct maculae of yellowish pubescence on lateral side behind humerus. Body intermixing sparse long light-brown setae on head, pronotum, elytra and legs. Same setae somewhat sparsely on scape, and densely on pedicel, antennomere III, and underside of IV–VII. Elytra with tufts of short black bristles on each tooth of the ridges and sparsely with the same bristles along suture and lateral margin.

Head with several deep punctures on frons and occiput. Eye with upper and lower lobes connected by 1–3 rows of ommatidia; lower lobe transverse, LED/LEW = 0.7–0.8, LED/GL = 0.9–1.0.

Antennae 1.6 times as long as body length; relative length of each antennomere, from scape to antennomere XI, as follows: 1.0–1.1: 0.2–0.3: 1.3: 1.5: 1.1–1.2: 1.0: 0.9: 0.8: 0.7: 0.7: 0.7.

Pronotum slightly wider than long, PL/PW = 0.9, PW/EHW = 1.0–1.1, with rough dense distinct small punctures throughout; disk with indistinct transversal swelling anterior to middle, a pair of spinous tubercles latero-dorsally on middle, a pair of antler-like protuberances on center, the protuberance branched at base into short anterior process and long posterior one; sides constricted behind apex, swollen laterally in middle, almost parallel in basal 1/4. Scutellum square in shape.

Each elytron relatively short, EL/BL = 0.6, EL/EHW = 2.0–2.3, with deep punctures on base and becoming indistinct apically; sides slightly expanded laterally toward middle and arcuately narrowed apically, with angularly pointed apex; disk roundly depressed on latero-dorsal side behind base (= area between basal protuberances and lateral side), thence convex dorsally with several small spinous tubercles on base and humerus, two protuberances behind base near middle, of which the anterior one is small but the posterior one is well developed, serrate longitudinal ridge from behind the protuberance to apical 1/5, and two indistinct serrate ridge on latero-dorsal side,

Mesocoxal cavity narrowly opened laterally.

Hind wing ( Fig. 12b View FIGURES 9–12 ) well degenerated, without distinct veins except for upper one (probably corresponded with C+Sc+RA).

Male genitalia ( Fig. 16 View FIGURES 13–16 ) with tegmen, in dorsal view, widest at middle, slightly curved in lateral view; parameres slender, slightly curved in ventral view, obtusely projected at base of ventral side and depressed behind the projection, arcuately narrowed apically; each lobe slightly expanded toward rounded apex, with several long setae arising from apical half of outer side and concentrated apically, with short setae on basal projection of ventral side; ring part expanded at middle of tegmen, thence arcuately narrowed basally. Median lobe gently constricted behind middle in dorsal view, gently curved in lateral view; ventral plate slightly longer than dorsal plate, acutely pointed at apex; dorsal plate with spear shaped apex; basal strut bifurcated from basal 2/5 of median lobe. Endophallus 2.5 times as long as median lobe, subdivided into BPH, MPH (MT, CT, PB), and APH; BPH slightly longer than median lobe, with basal swelling on ventral side near CS; MPH with MT+CT short, nearly half length of median lobe, cylindrical in MT, weakly constricted and curved at proximal area of CT, slightly dilated distally, projected ventrally in distal area of CT, with LSp unidentate and irregularly arranged lineally on lateral sides of CT; PB dilated distally, with SSp minute and densely covered almost of PB; APH small, almost fused with PB, roundly swollen together with PB, with a single ED distally on dorsal side.

Female (n = 3): BL = 6.1–8.0 mm, BW = 2.3–3.2 mm. Similar to male, but slightly rotund. Antennae 1.5–1.6 times as long as body length; relative length of each antennomere, from scape to antennomere XI, as follows: 1.1–1.2: 0.2–0.3: 1.1–1.2: 1.6: 1.2: 0.9–1.0: 0.8–0.9: 0.8: 0.7–0.8: 0.6–0.7: 0.6–0.7; relative ratio of body parts as follows: LED/LEW = 0.7–0.8, LED/GL = 0.8–0.9, PL/PW = 0.8, PW/EHW = 1.0–1.1, EL/BL = 0.6, EL/EHW = 2.1–2.3.

Etymology. The specific name is derived from the province name of the type locality.
