Antennal insertions exposed or concealed. Visible portion of procoxa projecting bellow prosternum with the trochantin at least partly exposed. Procoxal cavity externally open and internally closed. Mesocoxae contigous, with mesocoxal cavity laterally open. Tarsal formula 5-5-4. Number of ventrites 5 or 6 with 2 connate. Body length 5-20 mm. Elongate, usually slender, pubescent, often brightly colored. Antennae long. Head not abruptly constricted posteriorly. Prothorax expanded at about anterior third, then narrowed, sides rounded without margins. Quick identification Oedemeridae includes a number of elongate, slender beetles in which the prothorax has a characteristic shape. It is narrowed at either end but always widest at the anterior 3rd or 4th, and the lateral margins are completely absent. In addition, the apical maxillary palpomeres are often expanded and truncate, the head never forms a neck, and the elytra are usually have weak longitudinal ribbing.
