Diagnosis: Aleochara prisca  differs from other Brazilians A. ( Aleochara  ) species by abdominal tergum VIII two times wider than long; apex of median lobe of the aedeagus toothless and apical one-third curved in lateral view (directed ventrad); anterior margin of each side of tergum IX of female with a weakly sclerotized area and rounded median angle.

Redescription: BL: 8.4 mm. EW: 2.2 mm. Head dark brown to black; pronotum predominantly yellowish, or yellowish with dark brown macula on central disc, or entirely dark brown; elytra predominantly yellowish, or yellowish with dark brown macula on disc, or dark brown with external sides lighter or lighter on latero-anterior angle; abdomen brown to dark brown, with posterior half of tergum VII to tergum X lighter, somewhat yellowish to rusty-brown; legs, antennae and mouthparts yellowish to brown. Dorsal surface glossy and covered with thin golden yellowish setae with setigerous pores impressed. Note: the color pattern is very variable in this species, which some individuals are very lighter than the others (for example: holotype), mainly pronotum and elytra.

Head: with setigerous punctation; disc with sparse pubescence directed mediad and anterad. Antennae with antennomere 2 half the length of first and slightly narrower than first; 3 longer than 2; 4 transverse; 5–9 similar in shape, clearly transverse, gradually slightly narrower than the apex, 5 distinctly wider than 9; 10 subquadrate to slightly transverse; 11 twice longer than the previous one, subtriangular in shape; 1–4 glossy with some long black setae; 5–11 dull and covered by very short white setae, some long black setae on apex of each antennomere and in 11 with long black setae on a transversal circular line in the middle of the 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 punctuation, denser than pronotum; setae directed posterad.

Abdomen: distinctly narrowed posteriorly, maximum width of tergum X about half of apical width of tergum VII; terga coarsely setigerous punctuated, similar to head, pubescence sparse directed posterad.

Male: tergum VIII two times wider than long ( Fig. 26View FIGURES 26–31); posterior margin emarginate at the middle, not serrated. Sternum VIII as wide as long; posterior margin broadly rounded and truncate medially ( Fig. 27View FIGURES 26–31); internal surface with many short and dense setae directed anterad; Tergum IX with asymmetrical ventral struts, the left shorter than the right, the left with one accessory short arm directed laterad. Tergum X with anterior margin truncate and posterior margin very slightly emarginate at the middle ( Fig. 28View FIGURES 26–31). Aedeagus: median lobe elongate and bulbous at base ( Fig. 30View FIGURES 26–31); apex toothless, ventral margin curved in apical one-third in lateral view, directed ventrad ( Fig. 31View FIGURES 26–31).

Female: tergum VIII two times wider than long; posterior margin truncate ( Fig. 32View FIGURES 32–34). Sternum VIII wider than long; posterior margin broadly rounded, somewhat pointed at the middle, some short setae restricted to posterior margin ( Fig. 33View FIGURES 32–34). Tergum IX without ventral struts; anterior margin of each half of tergum IX with a weakly sclerotized area and rounded median angle. Tergum X with anterior margin truncate and posterior margin emarginate at the middle ( Fig. 34View FIGURES 32–34). Spermatheca not found.

Geographical records: Material examined: Brazil (Amazonas: Manaus and Tefé) ( Fig. 75View FIGURE 75).

Natural history: associated with decomposing pig carcass.
