Aleochara (Xenochara) puberula Klug

( Figs. 3 , 29, 31 )

Diagnosis (based on Klimaszewski 1984: 46–48). Aleochara puberula may be distinguished from other Aleochara species by having the antennal segments 5–10 slightly transverse, the mesosternum completely carinate along midline, the basal impressions of the first three visible abdominal terga glabrous and the shape of male sternum 8, which is broadly rounded apically. Length 4.0–7.0 mm.

Distribution. Cosmopolitan ( Klimaszewski 1984).

Bionomics. Adults were collected from carrion, human feces, cattle and sheep dung ( Klimaszewski 1984; Klimaszewski & Jansen 1993). This species has been reported by Peschke & Fuldner (1977) from decaying plant substances and large cadavers in African savannas. A list of host records was given by Maus et al. (1998).
