The egg, larva, and pupa of Brathinus are described for the first time on the basis of reared specimens of B. nitidus LeConte from New Hampshire. Adult characters previously used to justify placement of Brathinus in Omaliinae are shown to be plesiomorphic features. Three larval characters are suggested as probable synapomorphies of Omaliinae; their presence in Brathinus supports placement of the genus in that subfamily. Adult and possibly larval characters appear to support a sister-group relationship between Brathinus and Anthophagus + Psephidonus (=Geodromicus) + Microedus + Hygrogeus. A hymenopteran parasitoid, most probably Codrus sp. (Proctotrupidae) is reported from one B. nitidus larva.
