Aleochara verberans Erichson, 1839: 164 View in CoL (original description). Klimaszewski & Génier 1986: 115 (lectotype desigantion, as subgenus Xenochara ). Newton 2022 (as valid species).

Type locality: “Colomb.” = Colombia, after Klimaszewski & Génier (1986) .

Type material. Not seen. Lectotype deposited in ZMHB ( Klimaszewski & Génier 1986).

Additional material. Deposited in CESP 4 specimens: from Brazil, Paraná, Castro, 28. V .2006, collected in mammal feces, P. Grossi e D. Parizotto col. Deposited in MZUSP 6 specimens ; Brazil, S„o Paulo, S„o Paulo (cited as “ Ypiranga ”), without information about date and collector .

Diagnosis. Aleochara (X.) verberans is similar to A. puberula and differs from it by antennomere 4 conspicuously transverse, two times wider than long ( Fig. 16 View FIGURES 15–22 ), and elytra with each posterolateral margin slightly emarginate ( Fig. 30 View FIGURES 29–31 ).

Redescription. Male: maximum body length 6.0 mm, maximum elytral width 1.5 mm. Body brown to dark brown with appendages (antenna: two basal antennomeres only), legs and elytra (gradually towards apex) lighter ( Fig. 2 View FIGURES 1–8 ). Dorsal surface of body 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 long carina on each side of midline, attaining the gular suture. Neck absent. Antenna reaching base of elytra; antennomere 1 longer than 2; antennomere 2 subequal in length to antennomere 3 ( Fig. 16 View FIGURES 15–22 ); antennomere 4 two times wider than long; 5–10 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 dispersed; 5–11 covered by very short white setae, with some long black setae on apex of each antennomere, particularly 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 long and b-sensilla short and sharp apically. Mandibles symmetrical, without internal teeth. Maxillary palpomere 2 and 3 about the length; palpommere 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 slightly emarginate ( Fig. 30 View FIGURES 29–31 ). Hind wings developed. Mesoventrite completely carinate, mesoventrite process somewhat sharp and longer than metaventrite process, both joined. Abdomen: distinctly narrowed posteriorly; pubescence sparse directed posterad. Tergum VIII with posterior margin weakly emarginate at the middle, not serrated ( Fig. 39 View FIGURES 39–45 ). Sternum VIII with posterior margin broadly rounded and truncate medially ( Fig. 41 View FIGURES 39–45 ). Aedeagus elongate ( Figs. 42–44 View FIGURES 39–45 ); median lobe of the aedeagus with ventral margin curved in apical one-third in lateral view, directed ventrad. Female: similar to male, except abdominal tergum VIII with posterior margin truncate ( Fig. 40 View FIGURES 39–45 ). Spermatheca S-shaped, wtihout coiled duct ( Fig. 45 View FIGURES 39–45 ).

Geographic records. New records: Brazil: S„o Paulo (S„o Paulo) and Paraná (Castro). Literature records: Mexico, Colombia, Venezuela, Peru, Brazil, Paraguay, Argentina, Uruguay and Cuba ( Caron et al. 2008, Newton 2022). Until then, no specific locality in Brazil was known for A. (X.) verberans (Asenjo et al. 2013) ( Fig. 94 View FIGURE 94 ).

Biological notes. Specimens were collected from mammal feces.
