Subgenus Xenochara Mulsant and Rey, 1874 (Fig. 1–28) Klimaszewski 1984 Diagnosis. Species of this subgenus are distinguished by the following combination of characters: pronotum evenly pubescent (Fig. 1, 11, 20); mesoventrite with complete or almost complete carina, carina is as long as mesoventrite or slightly shorter; last article of maxillary palpus varying in length, from 1/3 to 3/4 length of penultimate article. Remarks. There are many different evolutionary linages in this subgenus that were formerly recognized as species groups (see Klimaszewski 1984) and Xenochara is not likely monophyletic (Maus 2000). Habitats diverse: various decaying organic matter, rotting mushrooms, moss, animal droppings, and forest litter.
