Introduction
Plesioglymmius s. str. is a subgenus with three known species from Sumatra, Borneo, Sulawesi, and Mindanao.Characteristics
The apical stylet of the antenna is short but distinct. The clypeal setae are present. The median lobe of the head is oval and separated from the clypeus by a broad depression. The antennal sclerites are well separated. The medial margins of the temporal lobes are straight. The orbital grooves are present. The postorbit is evenly convex and has a postorbital tubercle. The temporal setae are present or absent. Most of the ventral surface of the head is pilose. There are 2-4 pairs of postlabial setae.

The paramedian grooves of the pronotum are deep and long, about 0.95 of the length of the pronotum. Both median and paramedian grooves are punctate, but this is partly hidden by coarse pollinosity. The base of the elytron opposite interval I forms an angulate tooth. Both sexes have enlarged pits on abdominal sternum IV. Each abdominal sternum has a double transverse row of punctures.
