Diagnosis. This species is readily distinguished from other Dromoceryx species by the dark piceous to black main body coloration, and by small yellow spots on elytra. New species is most similar to D. dorsalis , the two species can be diagnosed easily by elytral pattern and microsculpture.

Description. Length 3.3–3.4 mm. Dorsum of head, clypeus and labrum black; mandibles dark brown; palpi and anten-nae testaceous. Mentum brown. Pronotum black, with brownish lateral margins. Elytral disc black, epipleura dark brown. Elytral pattern consist of two brown, semilunar humeral maculae, extended from lateral margin to third or second striae, and two apical macula on intervals 5-7, very narrowly joined along apical margin. Ventral surface black, except for testaceous meso-sternum, coxa and base of sternites I and II.

Head. Mandibles short, with wide base; labrum wider than long, rectangular, with six setae along apical margin; mentum with rectangular tooth; clypeus with two lateral setae; eyes convex, with two pairs of supraorbital setae. Disc of head with isodiametric to slightly polygonal microrreticulation.

Pronotum. Anterior margin widely interrupted, lateral margins narrow, basal rebording complete; anterior transverse impression absent; posterior transverse im-pression very shallow; median longitudinal impression moderately shallow; disc mod-erately flat, basal angles obtuse. Sides broadly rounded. Disc of pronotum irregularly reticulated, with slightly transverse meshes medially to strongly transverse laterally. Pronotum with two setae along each lateral sides, one in hind angle and one in anterior half just before maximal width.

Elytra. Intervals moderately flat, striae deep, minutely punctate; elytral apices truncate. Microreticulation faint, consist of strongly transverse sculpticells. Elytra with two setae in interval 3, one seta just before mid-length, one seta in apical 1/3 rd.

Hind wings. Macropterous.

Legs. Claws dentate with 5 teeth of about equal length at either side; 1st-3st tarsomeres of male protarsus dilated and with adhesive pads ventrally.

Male genitalia. Length 0.95-1.00 mm. Aedeagus elongate, ventral side straight, apex relatively wide and truncated; endophallus with several microtrichial patches and ventrally with two groups of small spines ( Fig. 3).

Female genitalia. Unknown.
