( Fig. 2 , 28, 32 )

Diagnosis. Aleochara bonariensis may be distinguished from other Aleochara species by its body robust and compact, the antennal segments 4–6 distinctly transverse, both head and pronotum sparsely pubescent, the mesosternum not carinate along midline and the elytra with two latero-medial brown spots. Length 5.0–7.0 mm.

Distribution. Mexico, Colombia, Venezuela, Suriname, French Guiana, Brazil, Paraguay, Argentina, Cuba (Newton, unpublished database).

Bionomics. Aleochara bonariensis has been found to be the most abundant staphylinid species associated with rabbit carcasses, Oryctolagus cuniculus Linnaeus ( Lagomorpha , Leporidae ) at an urban area of Northern Parana State, Southern Brazil (da Silva & Dos Santos 2012).
