description: Solariola angelae n. sp.
Fig. 9: A–F; Fig. 10–11: I; Fig. 12: (9).
Type locality. Sicily, Caltanissetta, Niscemi; Niscemi Coarn Oak Wood.
Holotype ♂. With following labels: 1) Caltanissetta, Monti Erei, Niscemi, Sughereta di Niscemi 300 m s.l.m. 02.III.2013 vaglio Baviera C. & Bellò C. Leg. [white printed], 2) Holotype ♂ [red printed], 3) Solariola angelae Det. Baviera 2013 [white printed] (MZCU).
Paratypes. 75 ♂♂♀♀. Same holotype data; same locality, 19.III.2010; ditto, 22.XII.2013; ditto, 10.XII.2014 (CBA, CBE, GOS, MSNG, MSNM, ECO).
Diagnosis. A medium to large brownish-red Solariola (3.00 mm) with pronotal setae longer than elytral ones, which are not raised on elytral surface and not longer than elytral punctures, long funiculus, with only segments 5 and 6 wider than long. Aedeagus with very wide apex, almost triangular-shaped.
Holotype description. Body length 3.09 mm, maximum width of elytra 0.98 mm. Rostrum slightly longer than wide (width/length ratio 0.9), confusedly and deeply wrinkled, with narrow furrow, subparallel rostral carinae. Underside and dorsum at base of rostrum very densely covered with short whitish-yellowish spatulate umbricate setae. Apex and base of rostrum with short and sparse recumbent bristles pointing backward, these bristles recumbent and visible on both sides and on upper surface of carinae. Antennae slender and long, scape very long and comparatively wide, slightly curved at proximal third, regularly thickened from base to apex, funicle less than 8 times longer than wide, segment 1 of funicle clavate, about 3 times longer than wide, segment 2 shorter and more than twice longer than wide, 3 slightly longer than wide, 4 almost as long as wide, 5 wider than long, 6 barely longer than wide, 7 wider than long; club three-segmented, oval, about twice longer than wide (width/length ratio 0.58), densely covered with short setae. Prothorax slightly longer than wide (width/length ratio 0.86), rounded on sides, widest in the middle, disc irregularly sculptured by large deep punctures merged with smaller shallower ones which bear a long recumbent seta, these pairs of points are more distant each other on disc than on sides, their interspaces smooth, glossy, the strongly inclined centripetal setae inserted in smaller punctures are on average length less than 3 times the average diameter of the larger points. Elytra oblong elongate, oval, narrower at base than maximum width of prothorax, almost twice long their overall width (width/length ratio 0.52), humeri obliquely rounded, subparallel sides regularly convergent to apex, scarcely and very regularly curved, maximum width at mid length, narrowing apically. Interstriae flat, clearly demarcated and sometimes incised by points of striae, minutely punctured, points lower in number than those of striae, each bearing a long (≤ 0.07 mm) curved laterally flattened and never raised seta (very slightly raised only at elytral apex), often the apex of a seta touch the base of the following one, very few setae on elytral apex are spatulate and recumbent on elytral surface. Elytra lateral declivity starting after the 2nd stria. Aedeagus long, slightly curved, sclerotisation of sides very broad on basal two third, sides strongly convergent just after base, then slightly widened, with apex slightly arched, almost triangular-shaped and regularly curved; long lamella triangular, covered on sides, medially raised.

Etymology. This new species is dedicated to my wife Angela, as an acknowledgment of her patience, availability and collaboration through which it has been possible to collect this new species.
Distribution. Caltanissetta, Niscemi Cork Oak Wood (Fig.12).
Affinities. This species is closely related only to S. ruffoi, sharing with it elytral setae inclination and rounded sides of pronotum, and differing from it by elytral shallow punctation, setae length, pronotum and aedeagus shape and lamella length.
Ecology. Adults of S. angelae have been sifted from the leaf litter of an old Quercus suber forest growing on moist sandy soil.
