Xenochara Mulsant & Rey, 1874: 344, as subgenus of Baryodma Thomson, 1858. Type species: Aleochara decorata Aubé, 1850 (fixed by Mulsant & Rey (1874) by monotypy).
Polychara Mulsant & Rey, 1874: 348, as subgenus of Baryodma Thomson, 1858, including 19 species. Type species: Aleochara discipennis Mulsant & Rey, 1853, fixed by Fenyes (1918: 24) (subsequent designation). As synonym of Xenochara Klimaszewski (1984: 34), Assing (2009: 36) and Newton (2022).
Homoeochara Mulsant & Rey, 1874: 414, as subgenus of Baryodma Thomson, 1858, including 3 species. Type species: Aleochara sparsa Heer, 1839, fixed by Fenyes (1918: 23) (subsequent designation), error: as Aleochara sparsa Fairmaire & Laboulbène, 1856 in Mulsant & Rey (1874). As synonym of Xenochara Assing (2009: 36) and Newton (2022).
Dyschara Mulsant & Rey, 1874: 425, as subgenus of Baryodma Thomson, 1858. Type species: Aleochara inconspicua Aubé, 1850, fixed by monotypy. As synonym of Xenochara Assing (2009: 36) and Newton (2022).
Rheochara Mulsant & Rey, 1874: 294, as genus, without species included. Type species: Ocalea spadicea Erichson, 1837, fixed by subsequent monotypy (the first species included by Mulsant & Rey 1875: 3). As synonym of Xenochara Assing (2016: 270) and Newton (2022).
Metalea Mulsant & Rey, 1875: 299, as subgenus of Ocalea Erichson, 1837. Type species: Ocalea procera Erichson, 1839, fixed by monotypy. As synonym of Xenochara Assing (2016: 270) and Newton (2022). Note: Ocalea procera Erichson, 1839 is treated as a junior synonym of Ocalea spadicea Erichson, 1837 (Scḩlke & Smetana 2015).
Ophiochara Bernhauer, 1901: 439, as subgenus of Aleochara Gravenhorst, 1802, including 2 species. Type species: Aleochara breiti Ganglbauer, 1897, fixed by Fenyes (1918: 24) (subsequent designation). As synonym of Xenochara Assing (2009: 36) and Newton (2022).
Isochara Bernhauer, 1901: 440, as subgenus of Aleochara Gravenhorst, 1802, including 2 sepcies. Type species: Aleochara tristis Gravenhorst, 1806, fixed by Fenyes (1918: 23) (subsequent designation). As synonym of Xenochara Klimaszewski (1984: 35), Assing (2009: 36) and Newton (2022).
Notiochara Casey, 1906: 134, as genus, including 2 species. Type species: Notiochara subaspera Casey, 1906, fixed by Fenyes (1918: 24) (subsequent designation). As synonym of Xenochara Klimaszewski & Jansen (1993: 68) and Newton (2022).
Euryodma Reitter, 1909: 24, as subgenus of Aleochara Gravenhorst, 1802. Type species: Aleochara brevipennis Gravenhorst, 1806, fixed by monotypy. As synonym of Xenochara Assing (2009: 36) and Newton (2022).
The diagnosis of the subgenus was modified by Park & Ahn (2010). The species of Aleochara (Xenochara) can be separated from other subgenera of Aleochara by the following combination of characters: body compact and robust (somewhat less than Aleochara (Aleochara )); antennomere 4 and 5 wider than long or slightly longer than wide; antennomeres 6–10 moderately transverse; mandibles symmetrical, without internal teeth; maxillary palpomere 4 one-third to three-fourths length of palpomere 3; labium with bifurcated glossa; beta seta of labial palpi long; pronotum uniformly pubescent; mesoventrite completely carinate, sometimes the carina is slightly shorter; spines of lateral margins of protibia and mesotibia present, but absent in metatibia.
Note: In some Brazilians species, the labral b-sensilla is long, not very short (sharpened or rounded apically) as in Park & Ahn (2010, mentioned as labral b-seta); and the carina on each side of the midline of the ventral surface of the head is very short, and not long and attaining the gular suture as in Park & Ahn (2010).
