description: Genus Neobelocera Ding & Yang, 1986
Type species: Neobelocera asymmetrica Ding & Yang, 1986 (original designation).
Diagnosis
The genus Neobelocera is easily distinguished from other genera of Tropidocephalini by the following combination of characters: antennae with first segment subsagittate, markedly flattened, a longitudinal carina down middle, the ventral apical angle longer than dorsal apical angle (Figs 1E, 2B, 3E, 4B); when postclypeus viewed in profile, apical part of median carina bent at rounded angle, not at right angle (Figs 1D, 3D) (Hou & Chen 2010; Hu & Ding 2014).
Host plant
Bamboo.
Distribution
Oriental region (China).
