(Figures 2, 16, 30, 39–45, 94)
Aleochara verberans Erichson, 1839: 164 (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), and elytra with each posterolateral margin slightly emarginate (Fig. 30).
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). 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); 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). 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). Sternum VIII with posterior margin broadly rounded and truncate medially (Fig. 41). Aedeagus elongate (Figs. 42–44); 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). Spermatheca S-shaped, wtihout coiled duct (Fig. 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).
Biological notes. Specimens were collected from mammal feces.
