Hyposerica opaca

Adults reach a length of about 12 mm. They have an egg-shaped body. The upper and lower surfaces are dark reddish-brown (with the underside somewhat lighter). The entire upper surface (with the exception of the shiny clypeus) is dull and strongly tomentose without any opalescent sheen. There are a few scattered erect hairs on the upper surface and the pronotum and elytral margin are sparsely fringed with light brown hairs. The antennae are yellowish-brown.^[3]
