Melyris bicolor, copyright Efim.

Belongs within: Cleroidea.
Contains: Listrini, Dasytes, Malachiinae.

The Melyridae are a group of relatively soft-bodied beetles that are usually predacious or scavengers as larvae but commonly flower-feeders as adults. The elytra are commonly reduced in the subfamily Malachiinae but not in the subfamilies Melyrinae and Dasytinae. Melyrinae are often brightly coloured (bicoloured as in Malachiinae or metallic blue or green) whereas Dasytinae are usually uniformly black, brown or yellow. Dasytinae have the first tarsomere on all legs as long as or longer than the second whereas it is shorter in Melyrinae. Within the Dasytinae, members of the tribe Dasytini typically have tarsal claws with a basal tooth, and tarsomere 4 shorter than 3 on all legs (Mayor 2002).

Characters (from Lawrence & Britton 1991): Oblong to elongate, somewhat flattened, soft-bodied, usually clothed with decumbent hairs and scattered erect setae, either uniformly black or grey or bicoloured with red or yellow and blue or black . Labrum well sclerotised; tarsal claws toothed or provided with a pair of fleshy appendages; elytra sometimes very short, exposing several abdominal tergites; eversible vesicles often on prothorax, mesothorax and abdomen. Larvae elongate, slightly flattened, lightly sclerotised, except for head, T9 and thoracic plates, red or pink in colour; head with long epicranial stem, no median endocarina, and lightly sclerotised gular and para-gular areas, so that head capsule appears to be open behind ventral mouthparts; mesal appendage at base of mandible.
