Antennae elevensegmented, slightly serrate, without club. First antennomere about 1.8 times as long as broad at apex. Second antennae subequal in length and width, about 0.4 times as long and about 0.8 times as narrow as the first. Third antennomere about 1.3 times as long and wide at apex, about 1.7 times as long and about 1.3 times as wide as second antennomere. Fourth antennomere 1.4 times as long as broad at apex, 1.4 times as long as and about 1.3 times as broad as third antennomere. Fifth and sixth antennomeres equal to fourth antennomere. Seventh antennomere about 1.8 times as long as wide at apex, about 1.2 times as long as and equal in width to sixth antennomere. Eighth antennomere about 1.9 times as long as wide at apex, as long as and slightly narrower than seventh antennomere. Ninth antennomere about 1.9 times as long as wide at apex, about 0.9 times as long and about 0.8 times as narrow as eighth antennomere. Tenth antennomere 2.5 times as long as wide at apex, about 1.1 times as long as ninth antennomere. Eleventh antennomere about 3.2 times as long as broad at middle, about 1.3 times as long and broad as tenth antennomere. Pronotum almost bell-shaped, about 1.3 times as long as wide at apex, about 0.9 times as long as wide at middle, about 0.8 times as long as wide at base, without lateral pronotal carinae. Disc densely punctate. Elytra oval, broadest at humeri, about 3.4 times as long as broad at base, about 1.5 times as long as broad at middle, about 1.6 times as long as broad at apical fourth, about 2.2 times as long as pronotum, with convex humeri. Elytral striae absent. Metaventrite weakly convex, about 2.9 times as long as length of mesocoxal cavity. Metepisternum narrow. Abdomen convex. First ventrite about 1.4 times as long as length of mesocoxal cavity. Second ventrite equal in length to first ventrite. Third ventrite about 0.6 times as long as second ventrite. Fourth ventrite equal in length to third ventrite. Fifth ventrite about 1.7 times as long as fourth ventrite, covered by elytra. Legs long. Femora weakly clavate. Tibiae apically expanded, with two spurs. Tarsi long, five-segmented. Tarsomeres first-third long conical. Fourth tarsomere weakly bilobed. Claws weakly toothed. Body length 3.1 mm.

Comparison. The new species differs from Granulobium whitei Li, Philips et Cai, 2023 in the punctate pronotum, the larger eyes, densely punctate elytra, and the larger body size.
