General distribution.

Europe: Croatia, France (mainland, Corsica), Hungary (?), Italy (mainland, Sicily, Sardinia), Portugal (mainland), Romania ( south–west ?), Slovenia, Spain (mainland, Balearic Is.), Switzerland (Minelli 1982, Kos 1992, Stoev 1997); the species is probably present also in North Africa (Tunisia) (cf. Minelli 1982); records from Central Europe (Austria, Belgium, Germany, Great Britain, Luxembourg, The Netherlands) are mostly related to anthropogenic habitats ( Rémy and Hoffmann 1959, Eason 1964, Jeekel 1977, Barber 1985, Spelda 1991, 2005, Lock 2000, Lindner 2007); introduced to North America (Eason 1964). The European distribution of the species has been reviewed by Lindner (2007).

Chorotype.

W-Mediterranean.

Ecological notes.

320-1600 m; recorded from the Mesomediterranean to the Montane vegetation belts, in Quercus ilex woods (2 sites), Fagus sylvatica woods (1 site), Pinus laricio woods (1 site).

Remarks.

Subgeneric assignment according to Minelli (1982). According to Léger and Duboscq (1903: 312), specimens from Bastia, Cap Corse, Ajaccio and Corte ( “Région chaude") are small in size (25-30 mm long), with 63-67 rarely 71 (males), and 67-69 (females) leg pairs, whereas those from Corte and Vizzavona ( “Région montagneus") are larger in size (50-70 mm long), with 75-77 rarely 65 (males), 77-79 (females) leg pairs. The examined material (2 ♂♂, 4 ♀♀, 1 immature, 1 unsexed) is not consistent with this pattern.

Chaetechelyne duboscqui and Chaetechelyne corsica are both probably conspecific with Henia vesuviana according to Minelli (1982).
