Genus Acrotona Thomson, 1859

Acrotona Thomson, 1859: 38 (Type species: Aleochara aterrima Gravenhorst, 1802).

Colpodota Mulsant & Rey, 1873: 153 (Type species: Homalota Mulsant & Rey, 1852).

Solenia Mulsant & Rey, 1873: 158 (Type species: Colpodota simulans Mulsant & Rey, 1873 = Aleochara fungi Gravenhorst, 1806).

Arcromota Casey, 1893: 300 (Type species: Arcromota fusiformis Casey, 1893).

Eustrigota Casey, 1911: 165 (Type species: Strigota seclusa Casey, 1911).

Diagnosis. Members of the genus Acrotona can be distinguished from other athetine genera by combination of the following characters: body fusiform, more or less convex dorso-ventrally; infraorbital carina complete; pronotum transverse, widest behind middle, pubescence directed posteriorly in midline in most; hypomera invisible in lateral aspect; mesoventral process beyond middle of mesocoxal cavities; metatarsomere 1–4 subequal in length; abdomen narrow apically, with conspicuous macrosetae; segmental margins of abdomen minutely crenulate; abdominal tergites III–V impressed in basal region, VII longer than VI; bursa of spermatheca more or less spherical and extended to elongate neck, duct regularly coiled posteriorly and often with swelled apex (Fenyes, 1920; Yosii & Sawada, 1976; Seevers, 1978; Lohse et al., 1990; Klimaszewski1 et al., 2015).

Distribution. Worldwide.

Remarks. Acrotona is very similar to Mocyta Mulsant & Rey and Strigota Casey, but can be distinguished by the diagnosis above and a key distinguishing the genera presented by Klimaszewski et al. (2015).
