Danacea (Allodanacaea) gorditana Liberti, 2007

( Figs 7 , 24 )

Danacea (Allodanacaea) gorditana * Liberti, 2007b: 5 (Loc. typ. Asinara Island, Sardinia).

Material examined. Sassari prov.: * Isola Asinara , “VII-VII. 1903, leg. S. Folchini ”, 1 ♂, 1 ♀ (holotype and allotype, MCSNG) . Isola Asinara , “Cala d’Arena, 1.VII.1987, leg. V. Vomero ” 1 ♀ ( CNBFVR) . * Capo del Falcone “ 18.VI.2003, leg. G. Liberti ”, 3 ♀ on blossoming Cistus sp. (paratypes, CLI) . * Penisola di Stintino , “ 18.V.2006, leg. P. Ponel ”, 2 ♂♂, 1 ♀ on Daucus sp. (mixed up with approximatly 140 specimens of Danacea sardoa sardoa ) (paratypes, CPN) .

Chorotype. Strict Sardinian endemic, limited to the north-western corner of the island in a very small area which includes Capo del Falcone and Asinara Island ( Fig. 24 ). Affinities: Central Mediterranean; rather well characterized, it shows some relations (mainly in the aedeagal structure) with two D. ( Allodanacaea ) species: D. nympha , which occurs in the nearby Alghero area, and D. constantini Liberti, 1985 , which is a strict Corsican endemic.

Notes. An apparently uncommon species, of which only the type specimens are known so far; it lives on flowers (e.g. Cistus , Daucus ), feeding on pollen. No other Allodanacaea species are known from the type locality of D. gorditana , but D. sardoa sardoa is common there and has been collected in numbers.
