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.
