Genus Neohemisphaerius Chen, Zhang & Chang, 2014

Type species.

Neohemisphaerius wugangensis Chen, Zhang & Chang, 2014.

Diagnosis.

Body hemispherical. Vertex about 2.5-3.9 times as wider than long along midline, anterior margin straight, posterior margin angulately excavated. Frons elongate, with median carina, lateral margins elevated. Clypeus with median carina moderately convex, median carinae with or without a tubercle process in middle. Pronotum depressed, edges elevated. Mesonotum subtriangular, anterior margin approximately straight. Forewings hemispherical, claval suture developed, without shoulder-like projections basally. Hindwing rudimentary, shorter than half length of forewing, venation indistinct and simple. Hind tibiae with 2 lateral teeth. Metatibiotarsal formula: (9, 10)-(4, 5)-2. Anal tube of male wide and short. Phallobase with pair of ventral hooks directed basad.

Distribution.

China (Guangdong, Guangxi, Hunan, Guizhou).

Discussion.

Neohemisphaerius is similar to Hemisphaerius Schaum, 1850 and Gergithus Stål, 1870, but it differs from the two genera by having a frons with a median carina, and forewings with a claval suture developed. The genus Neohemisphaerius runs close to Paramongoliana in the key by Meng et al. (2017). It differs from Paramongoliana in: frons with median carinae, without a row of pustules along the lateral margins; clypeus distinctly convex on disc in midline; forewings with irregular markings; phallobase with pair of ventral hooks directed basad.
