Chaeridiona semiviridis Pic. Uhmann 1958: 252   , 1964: 466 (catalog); Würmli 1976: 402 (revision); Kimoto 1999: 110 (distribution).

Head, pronotum, and elytra yellowish-ochre with medial metallic green spot; legs yellow; antennae reddishyellow with apical 4 antennomeres darker. Head: wedge-shaped; acutely produced between antennal bases; carinate medially; vertex deeply, densely punctate. Antenna: 2x length of head and pronotum combined; antennomere I robust; II ¾ length of I; III–V subequal in length, each 1.25 length of I; VI–IX shorter than preceding; XI pointed at apex. Pronotum: strongly convex; lateral margin slightly sinuate, rounded in middle; anterior angle with acute tooth; densely, coarsely punctate; medial longitudinal sulcus present; pronotal width 0.9–1.0 mm; pronotal length 0.7–0.9 mm. Scutellum: quadrate; punctate. Elytron: distinctly expanding apically; exterior apical angle angulate; humerus angulate, slightly produced; puncture rows 5–7 in deep fossa, punctures confused; interspaces 2 and 6 carinate apically; carina of interspace 4 interrupted in middle; interspace 8 carinate; elytral width 0.9–1.0 mm; elytral length 2.4–2.9 mm. Venter: pro-, meso-, and metasterna punctate laterally. Total length: 3.6–4.1 mm.

Comparative notes. This species can be distinguished from all other Chaeridiona   by the angulate exterior apical angle of the elytra and the metallic medial spot on the elytra.

Food plants. Adults have been collected on an unidentified ginger ( Zingiberales   ) and Costus   ( Costaceae   ).

Distribution. Thailand, Vietnam.
