Diagnosis. Aleochara (X.) repetita differs from A. (X.) leivasorum sp. nov. and A. (X.) lapidicola by having male tergum VIII with posterior margin emarginate and coarsely serrated (around 10 teeth) ( Fig. 69 View FIGURES 69–76 ); and female sternum VIII with posterior margin slightly emarginate ( Fig. 72 View FIGURES 69–76 ).

Redescription. Male: maximum body length 7.0 mm, maximum elytral width 1.5 mm. Body brownish to dark brown with appendages (antenna: antennomeres 1 and 2 only), elytra (except posterolateral regions) and posterior half of abdominal segments VII and VIII lighter. Body dorsal surface glossy; pubescent, appearing yellowish-brown in artificial light; setigerous pores impressed. Head: circular. Pubescence directed anterad. Eyes large and slightly prominent, twice the length of temples. Ventral surface of head with a very short carina on each side of midline. Neck absent. Antenna reaching base of elytra; antennomere 1 subequal in length to antennomere 2 and 3 ( Fig. 20 View FIGURES 15–22 ); antennomere 4 slightly longer than wide; antennomere 5 subquadrate; antenomeres 6–10 wider than long, gradually increasing in width towards apex; antennomere 11 two times longer than wide, length almost equaling two preceding antennomeres combined; antennomeres 1–4 glossy with some long black setae; antennomeres 5–11 covered by very short white setae, with some long black setae on apex each antennomere; 11 with long black setae on a transverse circular line at the apex of basal one-third of the antennomere. Labrum transverse; anterior margin with a-sensilla and b-sensilla long. Mandibles symmetrical, without internal teeth. Maxillary palpomere 2 and 3 about the same length; palpomere 4 about half length of 3. Gular plate broad. Thorax: pronotum transverse, posterior margin broadly curved; densely pubescent, with pubescence directed posterad and laterad elsewhere. Elytra shorter than pronotum; the same width with pronotum; elytra wider than long; densely pubescent, pubescence directed posterad; each posterolateral margin kindly rounded. Hind wings developed. Mesoventrite completely carinate; mesoventrite process somwhat sharp and longer than metaventrite process, both joined. Abdomen: distinctly narrowed posteriorly. Pubescence sparse directed posterad. Tergum VIII with posterior margin emarginate and coarsely serrated (around 10 teeth) ( Fig. 69 View FIGURES 69–76 ). Sternum VIII with posterior margin very slightly emarginate ( Fig. 71 View FIGURES 69–76 ). Aedeagus elongate ( Figs. 73–75 View FIGURES 69–76 ); median lobe of the aedeagus with apex strongly curved directed ventrad in lateral view. Female: similar to male, except for tergum VIII with posterior margin emarginate, somewhat U-shaped, not serrate ( Fig. 70 View FIGURES 69–76 ). Sternum VIII with posterior margin slightly emarginate (but, more conspicuous than the male) ( Fig. 72 View FIGURES 69–76 ). Spermatheca Lcurved and irregularly twisted duct ( Fig. 76 View FIGURES 69–76 ).

Geographical records. New records: Brazil: Mato Grosso do Sul (Bonito), Paraná (Toledo). Literature records: Panama: Chiriqui (San Félix), and Brazil: Pará (Uruará), Distrito Federal (Planaltina) and Paraná (Palotina) ( Buss et al. 2018) ( Fig. 94 View FIGURE 94 ).

Taxonomic notes. The name A. (X.) opacula Bernhauer, 1901 is here treated as junior synonym of A. (X.) repetita , after the study of the type material.

Biological notes. The specimens of A. (X.) repetita are often collected using pitfall traps baited with banana, meat or feces, from un-baited pitfall traps (but close to the pig carcass), or also manually in pig carcass.
