This species can be recognised easily by the wide and small size body (4.8–5.4 mm), strongly transverse, very densely punctate pronotum and uniformly yellow pale body colour.
Length 5.1–5.6 mm. Pale brownish yellow, with no dark elytral pattern (Fig. 17).
Head pale yellowish red-brown, slightly darker than pronotum, very distinctly microsculptured and very coarsely and deeply irregularly punctate. Punctures sometimes almost confluent, sometimes separated by over two diameters. Clypeus twice as long as labrum. Eyes very large and bulging, with a few small setae at posterior margin. Second supraocular seta located just anterad the posterior margin of eye. Temples very short, smooth. Scape with a very long subapical seta and several rather long setae; pedicel and antennomere III each with a single band of apical setae. Antennae pubescent from the mid-length of antennomere IV. Antennomeres IV and V each slightly shorter than antennomere III. Antennomere V 2.5 times as long as wide at apex.
Pronotum 1.25 times as wide as head, 1.57 times as wide as long, widest just behind marginal setae. Anterior margin straight, anterior angles effaced, sides broadly and evenly rounded, slightly sinuate towards posterior angles, which are acute and form a minute denticle. Punctation coarse, irregular and deep, somewhat sparser than on head, especially on the disc. Punctures sometimes confluent, especially towards the sides of disc. Lateral explanate margin narrow at apex, rapidly widened basally. Posterior pore right in front of angle. Basal grooves shallow. Pronotal base extended in a rounded median lobe. Furrow very short and fine and does not reach anterior margin (by about the length of antennomere I) or the base. Microsculpture as on head.
Elytra generally concolorous with pronotum, with the apical third perhaps slightly darker. Intervals 1, 3, 5 and 7 with several minute, barely visible setae. Microsculpture lighter than on head and pronotum, so elytra seem shinier than head and pronotum. Scutellum with similar microsculpture. Elytral apices weakly obliquely sinuate, rounded at suture. Striae shallow, crenulate. Interval 8 convex over most of its length, slightly flattened towards apex; interval 7 convex only at shoulder; other intervals slightly convex near base and flat at apex.
Tarsomere V with 3 pairs of ventral setae. Claws with 4 teeth. Venter testaceous, abdomen slightly infuscated. Metathoracic process margined, with 4 long setae. Abdominal sterna pubescent; the last two also with scattered longer setae.
In the holotype, last abdominal sternum with 6 setae (3 on each side), irregularly placed. One of the paratypes has 4 setae (two on each side) and one has 5 setae: 3 on one side and 2 on the other.
Aedeagus – Fig. 38. Aedeagal median lobe straight euventrally for much of length between basal bulb and slightly downturned, elongate, narrow apex with tightly rounded tip. Internal sac without apparent spicules.
