Abstract: GenusLabidolanguriaFowler, 1908 Labidolanguria Fowler, 1908: 9. Type species: Labidolanguria mucronata Fowler, 1908 by monotypy. Diagnosis. Antennal club composed of 4–6 antennomeres. Dorsal body surface with green or deep - green metallic luster. Compound eyes large and finely faceted. Pronotum with basal pronotal carina. Elytral epipleura absent, apex of elytra acute, with outer angle of elytra somewhat acute and produced, sutural angle acute but not produced. Prosternal process rectangular, with two long grooves along each side. Distribution. China (Xizang, Yunnan, Sichuan, Taiwan), India (Nilgiri Hills). Remarks. When Fowler (1908) established this genus, he only compared it with the genus Pentelanguria Crotch, 1876. Labidolanguria and Pentelanguria share a similar elytral apex, which is acutely pointed. Apart from the smaller and more slender antennae in Labidolanguria, the two genera can also be distinguished by the prosternal process, which is smooth and flat in Pentelanguria, whereas in Labidolanguria it is grooved laterally. The genera Labidolanguria and Tetraphala exhibit strong similarities in the structure of the antennae, pronotum, and prosternal process. However, they can be differentiated by the elytral apex, which is consistently truncate and bears small denticles in Tetraphala, while in Labidolanguria it is acute and lacks denticles.
