64. Hypocacculus (Nessus) ascendens Reichardt

Literature data. “ Sardinia ” ( Yélamos 2002; Mazur 2004). Cagliari prov.: Villasimius, 7.V.1969, PA, 1 ex ( Secq & Vienna 1999). Oristano prov.: Oristano, 30.IV.1985, SR, 12 ex ( Secq & Vienna 1999).

Chorotype. 4.02 AFM (Afrotropical-Mediterranean).

Italian distribution. Sardinia.

Ecology. No data exist on the Sardinian specimens; in Spain it is found both on coastal dunes and on carcasses in arid inland areas.

Notes. Due to their small size and the inconspicuousness of their diagnostic features, Hypocacculus ascendens , H. (Nessus) ferreri Yélamos and H. (Nessus) rubripes (Erichson) form a group of species of difficult identification, and it is highly probable that in the past all specimens were ascribed to the most anciently described taxon, H. rubripes (see notes under the following species). A careful and thorough revision of the specimens from the various collections and extensive field campaigns are necessary for a better definition of the distribution of these species.
