Murmidius campbelli species group

Body nearly circular; anterior clypeal margin smooth; lateral pronotal margins strongly convergent anterad; lateral pronotal impressions present; sublateral pronotal impressions absent; metaventrite extremely short, so that distance between mesocoxae is wider than between meso- and metacoxa and lateral region between metaventral femoral line and metacoxa is strongly transverse; antennal club strongly elongate, nearly twice as long as broad; if lateral carinae of mesoventral plate are present, then area between them and mesocoxae not microreticulate; tarsomeres 1–3 with conspicuously long setae; elytra with or without rows of punctures; hind wings reduced, narrow and short, non-functional.

Six strictly Neotropical species with remarkably large adults, externally very similar.
