Chorotype. 3.01 MED (Mediterranean).

Italian distribution. Emilia-Romagna, Tuscany, Umbria, Latium, Apulia, Basilicata, Sicily and Sardinia.

Ecology. Vienna (1980) suggests that the Italian distribution of this species corresponds to that of the holm oak ( Quercus ilex ), and that it feeds on xylophagous species associated with this tree. Yélamos (2002) reports capturing it in great numbers in decomposed, half-buried oak wood in spring and in damp weather, but also records it as present in the wood of other broadleafs and pines, always in very humid conditions.

Notes. In Penati and Vienna (2005, 2006a) the data referring to the specimen from San Gregorio (CUL) are erroneously given as “Monti dei Sette Fratelli, coll. Museo Genova” (see “Data collection”).
