15. Hister unicolor unicolor Linnaeus

Literature data. “All of Italy ” ( Bertolini 1904; Porta 1926). “ Sardinia ” ( Bargagli 1871; Bertolini 1872 –1878; Luigioni 1929; Barajon 1966; Vienna 1980; Audisio et al. 1995; Yélamos & Lackner 2004). Cagliari prov.: Cagliari, loc. Bingia Matta, 21.III.1973, CM, on dog carcass, 1 ex (CCMe).

Chorotype. 1.05 SIE (Sibero-European).

Italian distribution. All regions except Molise.

Ecology. Found prevalently on cow dung, more rarely on horse dung, and in manure, but can also occur on carcasses, in rot holes of trees, micromammal burrows and in rotten fungi. Seems to be associated with montane or at most hilly habitats, with a lower limit of 400–500 m in Italy; only exceptionally found at lower elevations.

Notes. No other data are known to me apart from those above. This suggests that the species is extremely rare in Sardinia, while it is amongst the most common and widespread in the hilly-montane areas of centralnorthern mainland Italy.
