The genera Hoploranomimus and Paracanthocinus have been synonymized with Neacanista based on following characters: 1) head distinctly narrower than prothorax, frons with a narrow and mesial line extending from the base of clypeus up to the apical margin of the pronotum, lower lobes of eyes longer than genae; 2) antennae slender, distinctly longer than body; 3) pronotum transverse, with a tubercle at each side; disc punctured, with a pair of tubercles at sides of middle; procoxal cavities closed posteriorly; 4) elytra elongate, distinctly broader than prothorax at base, gradually narrow from near apical 1/3, truncated and notched apically, marginal angles processed outwards, sutural angles rounded; disc punctured and longitudinally ridged, with a pair of tubercles at base and near scutellum, with a pair of bumps behind the tubercles; 5) mesocoxal cavities closed externally to mesepimera; 6) femora strongly clavate, mesofemora and metafemora pedunculate at basal 1/2, mesotibia with an oblique external preapical groove.

Distribution. Bhutan; China; Laos; Thailand.

Remarks. Gressitt (1940) mentioned the differences between Neacanista and Acanista Pascoe, 1864 in the original description. Actually, Neacanista is more similar to Trichorondonia Breuning, 1965b , but differs from Trichorondonia by antennomeres I-VIII not fringed with long hairs beneath, and mesotibia with an oblique external groove near apex.
