Murmidius ovalis species group
Body elongate oval, weakly convex; anterior clypeal margin microserrate; pronotum with lateral margins weakly convergent anterad; lateral pronotal impressions present; sublateral pronotal impressions present (may be indistinct in some specimens); distance between mesocoxae shorter than between meso- and metacoxa, and lateral regions of metaventrite between metaventral femoral line and metacoxa elongate, covered with large foveate punctures; area between mesocoxa and lateral carina of mesoventral plate not microreticulate; antennal club weakly elongate, at most 1.5 × as long as broad; tarsomeres 1–3 with short, inconspicuous setae; elytra with distinct rows of punctures; hind wings functional.
Three species, of which one is cosmopolitan, one Australian, and one SE Asian, relatively easily distinguishable by external characters, except for some specimens of the most variable M. ovalis , especially unusually small adults, which may require examination of the aedeagus to confirm identification.
