Description. Male.

Integument Color. Body black ( Fig. 1) except basal four antennal segments, and mentum and prementum usually red orange to light brown.

Vestiture. Eye usually with medial fringe of sparse, white hairs; postocular lobe with short white hairs ( Fig. 2); usually without postocular patch of white hairs, remainder of head with sparse white hairs; scutellum covered with dense white hairs, basal corners of pronotum with dense white hairs, remainder of pronotum, elytra, and legs with uniform, moderately dense white hairs; mesepisternum, metepisternum, apical portions of the first three and the last abdominal segments with dense white hairs, remainder of mesothorax, metathorax, and abdomen with moderately dense white hairs; pygidium with sparse white hairs, base usually with three small white patches of hair, one medial and two lateral ( Fig. 1).


Head. Short and broad, densely punctulate; frons with a weak median glabrous carina extending from frontoclypeal suture to vertex; with vague transverse sulcus between upper limits of eyes; posterior margin of eye protruding laterally, well separated from vertex; width of eye 1.2–1.5 times width of frons; ocular sinus 0.5–0.6 as long as width of eye; distance from base of antennae to apex of labrum about 0.42–0.54 as long as distance from upper limits of eyes to apex of labrum; antennal segments 1, 3, and 4 usually filiform, 2 moniliform, 5–10 eccentric, 11 subacute apically, 5–11 slightly broader than long; antenna reaching to humerus or slightly longer, 0.50–0.62 as long as length of elytra.

Prothorax. Disk campanulate ( Fig. 1); finely punctate; lateral prothoracic carina not reaching coxal cavity; short median impressed line on median basal lobe; prosternum separating procoxae for about 0.66–0.73 their length.

Mesothorax and Metathorax. Scutellum small, quadrate, with lateral posterior small teeth ( Fig. 1); elytron about twice as long as broad, dorsal surface flattened between humerus and medial margin; striae deep, punctate, strial intervals punctulate finely; striae 3, 4, 5 and 6 equidistant at base; striae 5 and 6 not abbreviated at base, humerus impunctate, usually glabrous; undersurfaces punctate; entire face of hind coxa finely, shallowly foveolate; hind femur constricted basally and apically, expanded medially to slightly less than width of coxa; without scattered spinules on inner ventral longitudinal carina; femur armed with inner subapical acuminate spine 0.5–0.6 as long as width of tibial base; lateral ventral carina sinuately emarginate apically, with blunt angulation; tibia robust, with weak lateroventral, lateral, and dorsomesal carinae, ventral carina absent; dorsal surface of tibia somewhat roughened, with fossa indistinct; dorsal carina indistinct; tibial corona with three to four spinules, mucro 0.11–0.20 as long as first tarsomere; without sinus at base of mucro; first tarsomere with indistinct ventral, lateral, and mesal carinae.

Abdomen. First sternum slightly flattened medially, about 1.10–1.35 times longer than remaining sterna, posterior margin straight; sterna 2–4 unmodified, fifth emarginate; pygidium punctate, convex in lateral view.

Measurements. Length (pronotum-elytra) 1.37–1.87 mm. Width 0.87–1.2 mm. Maximum thoracic depth 0.67–1.0 mm.

Genitalia. Median lobe moderate in length; in ventral view, ventral valve slightly sinuate on lateral margins, arcuate in lateral view, gonopore trumpet shaped; without hinge sclerites; armature of internal sac consisting of one large medial forked spine, cleft of fork about 0.5 in length of spine, apex of sac with a cluster of small denticles, apical 0.30 of sac covered with many fine denticles, and the other 0.55 with small spines ( Fig. 3). Lateral lobes slightly expanded apically, cleft to about 0.86 their length ( Fig. 4).


Similar to male but apical margin of last visible abdominal sternum straight.

Length (pronotum-elytra) 1.62–1.92 mm. Width 1.05–1.22 mm. Maximum thoracic depth 0.87– 1.0 mm.
