Belongs within: Carabidae.

The Rhysodinae are a group of ground beetles found as both adults and larvae in old, rotted logs (Lawrence & Britton 1991).

Characters (from Lawrence & Britton 1991): Black and shiny, subcylindrical to slightly flattened, head and pronotum with deep grooves that are often filled with dried organic material; antennae stout, moniliform, 11-segmented; mouthparts more or less concealed beneath expanded mentum; head strongly constricted posteriorly to form narrow neck; fore coxae globular, trochantins concealed, fore coxal cavities externally closed (internally open); mid coxal cavities moderately separated, laterally open; metasternum without transverse suture; legs relatively short, with weakly developed antenna cleaner on fore tibia, tarsal formula 5-5-5; abdomen with six ventrites, three connate. Larvae elongate, somewhat flattened and lightly sclerotised with short legs, no urogomphi, and transverse rows of asperities or interrupted ridges on T1 to 6 or 7; head prognathous, protracted; stemmata absent; antenna four-segmented; frontoclypeal suture absent; labrum fused; mandibular mola absent; maxillae and labium reduced, usually clothed with fringed membranes, maxilla with single mala, maxillary palp three-segmented, labial palp one-segmented; hypostomal rods present; legs six-segmented, with one tarsal claws; urogomphi absent; spiracles annular.
