Male (Fig. 1A). Length 2.09-2.22 mm; body reddish-brown, maxillary palpi and tarsi lighter. Head and pronotum (Fig. 1B) sparsely punctate. Head slightly wider than long, length from anterior margin of clypeus to head base 0.40-0.42 mm, width across compound eyes 0.44-0.47 mm; each eye composed of about 30 facets. Antennal clubs loosely formed by apical three antennomeres. Pronotum about as long as wide, length along midline 0.46-0.48 mm, maximum width 0.44-0.48 mm; lateral margins rounded at middle, constricted and nearly parallel at basal 1/3. Elytra wider than long, length along suture 0.66-0.72 mm, maximum width 0.77-0.83 mm; shallow discal striae reaching past 3/4 of elytral length; marginal sulcus complete; with slight denticle at humeral angle. Metaventrite with one pair of laminar projections (Fig. 1C) at middle. Mesotrochanter slightly protuberant at ventral margin; mesotibia with distinct apical spur (Fig. 1D). Abdomen
