Chvalaea species have a very distinctive habitus. The thorax is highly arched with the head seemingly placed ventrally. The abdomen is unusual in being heavily sclerotised, with the surface there roughened by small punctures. The femora and tibiae are adorned with long erect slender setae. The antennae are placed high on the head. The eyes do not meet above the antennae, but for both males and females they meet for the entire length below. The proboscis is short. The wings lack any distinctive anal lobe and the discal cell (dm) is rather elongate and with two veins emitting apically that are incomplete.
There are no Australian species described, but the hybotids placed here agree with the description of Chvalaea.
