Diagnosis.

The subgenus Xenochara can be distinguished by a combination of the following characters: body compact, robust, pubescent; antennomere 4 usually longer than wide (except Aleochara tristis , transverse); carina on each side of midline of ventral surface of head present, attaining or almost attaining gular suture (arrows, Figs 1b, 2b, 3b, 4a, 5a; Klimaszewski 1984: Figs 313, 319, 321); maxillary palpomere 4 usually long (1/3 to 3/4 length of palpomere 3); labral b-seta sharpened or rounded apically (arrows, Figs 1c, 2c, 3c, 4b, 5b); mandibular internal tooth absent or weakly present; β-seta of labial palpi long (Figs 1e, 2e, 3e, 4d, 5d); mesoventrite completely or almost completely carinate (Figs 1a, 2a, 3a); pronotum evenly pubescent; spines of lateral margins of fore- and meso-tibia present but absent in meta-tibia.

Remarks.

This diagnosis is modified from Klimaszewski (1984: 35). New diagnostic characters based on mouthparts are added, and these are consistent at the subgenus level.
