Diagnosis: Aleochara mundana is very similar to A. auricoma and A. prisca (specimens with head darker than pronotum) but it differs from them by antennae distinctly lighter than head; median lobe of aedeagus with hook-like apical tooth (directed dorsad); and tergum X of female truncate on posterior margin. Redescription: BL: 6.3 mm . EW: 1.7 mm . Head brown to dark brown, antennae lighter than head; pronotum yellowish to light brown with dark macula on the disc; elytra yellowish to light brown, slightly darker on lateralposterior angles; abdomen brown to dark brown with posterior half of tergum VIII to tergum X yellowish; mouthparts and legs yellowish to light brown. Dorsal surface glossy and covered with thin golden yellowish setae with setigerous pores impressed. Head: with setigerous punctuation; disc with sparse pubescence directed mediad and anterad. Antennae with antennomere 2 half length of first and slightly narrower than first; 3 longer than 2; 4 transverse; 5–10 similar in shape, each distinctly transverse; 11 twice longer than the previous one, semi-triangular in shape; 1–4 glossy with some long black setae; 5–11 dull and covered by very short white setae, with some long black setae on apex of each antennomere and 11 with long black setae on a transversal circular line in the middle of each antennomere; Thorax: pronotum with setigerous punctuation; setae directed posterad at the midline of the disc and directed posterad and laterad elsewhere. Mesoventral process truncate. Elytra with setigerous punctation, denser than those on pronotum; setae directed posterad. Abdomen: distinctly narrowed posteriorly; terga with coarse setigerous punctation, sparse pubescence directed posterad. Male: tergum VIII wider than long ( Fig. 17 ); posterior margin truncated and not serrate; some setae restricted to posterior margin. Sternum VIII wider than long; posterior margin broadly rounded ( Fig. 18 ). Tergum IX with ventral struts asymmetrical, the left shorter than the right ( Fig. 19 ). Tergum X with anterior margin truncate and posterior margin very slightly emarginate at the middle ( Fig. 19 ). Aedeagus: median lobe elongate and slightly bulbous at base ( Fig. 21 ); apex with hook-like tooth, directed dorsad ( Figs. 22 ). Female: tergum VIII wider than long; posterior margin truncate ( Fig. 23 ). Sternum VIII wider than long; posterior margin broadly rounded, somewhat pointed at the middle, some short setae restricted to posterior margin ( Fig. 24 ). Tergum IX without ventral struts. Tergum X with anterior and posterior margin truncate ( Fig. 25 ). Spermatheca not found. Geographical records: Material examined: Bolivia (Mapiri), Brazil (Amazonas: Manaus and Pará : Serra Norte and Tapajós) ( Fig. 75 ). Natural history: found in dung ( Sharp 1876: 71 ).
