 Type species. Latidrymus puskasi sp. nov., here designated.   
 Description. Body small, about 2.8–3.5 mm long, general facies rather broadly oval, weakly convex dorsally. Integument and vestiture dull, subshining; head, pronotum, scutellum, and fore wings deeply and rather coarsely punctate, midline of pronotum posteriad to collar, at transversal impression, and at base of posterior lobe as well as Y- or T-shaped median ridge on scutellum impunctate. Dorsum only with very short, inconspicuous pilosity.   
 Head short with relatively large, laterally protruding eyes. Antenna short, basi- and distiflagellum strongly thickened, spindle-shaped. Bucculae laterally concealing labium, reaching about middle level of eyes. Labium attaining between meso- and metasternum.   
 Thorax. Pronotum subtrapezoid, with anterior and posterior lobes subequal in length, separated by a strong transverse impression, with a distinctly delimited anterior collar; anterior lobe at transverse impression nearly parallel, rounded at anterior angles; posterior lobe strongly expanded posteriad of transverse impression; lateral margin evenly broadly laminate, terminating abruptly posteriorly, deeply concave at level of transverse impression; posterior margin nearly straight, with a broadly rounded expansion at the base of hemelytra. they have a very broad and vertical head, and the explanate lateral margin of the pronotum distinctly broadens at the transversal impression (CHOPRA & SINGAL 1982).   
 Scolopostethus Fieber, 1860 is a morphologically diverse genus distributed in the Old World, but some of the currently included species are clearly not congeneric with the type species (KONDOROSY 2013). Some of these are similar to the new genus, but they always have longer antenna and head, the lateral carina on the pronotum is not evenly broad, they lack a T-shaped carina on the scutellum (sometimes a Y-shaped carina is present), and their fore femur is not strongly incrassate, etc. (PÉRICART 1999). The same features distinguish the new genus also from Eremocoris Fieber, 1860 (Old World, mostly Palaearctic), Faelicianus Distant, 1901 (Philippines and Sulawesi) and Grossander Slater, 1976 (Australian and Oriental Regions), which are also more or less similar to Latidrymus in general appearance (e.g. BERGROTH 1918, KONDOROSY & FÁBICS 2015, PÉRICART 1999).   
 Austrodrymus Gross, 1965 (South and Western Australia) somewhat resembles the new genus too, but it lacks pronotal collar, and the posterior pronotal margin is not laminate (GROSS 1965).   
 The Afrotropical genus Testudodrymus Slater, 1993 has very short scape with a tooth-like lateral projection, the lateral and basal margins of the pronotum are straight, it lacks scutellar carina, and has unarmed fore femora (SLATER 1993).   
 Etymology. The generic name is derived from the Latin adjective latus, meaning broad, referring the ‘dumpy’ shape of the species, and the name of Drymus, the type genus of Drymini. The gender is masculine.   
 Diversity and distribution. The new genus is widely distributed in continental South and Southeast Asia (Fig. 16) from India (Meghalaya, West Bengal, Tamil Nadu) and southeastern China (Fujian) to Sumatra. It contains four species described below and probably also some undescribed.
