Lectotype description. Body length 2.51 mm, maximum width of elytra 0.75 mm. Rostrum confusedly and slightly wrinkled, 1.08 wider than long, with broad rostral furrow, subparallel raised rostral carinae slightly arched as to be closest at the middle. Underside of rostrum densely covered with whitish-yellowish spatulate setae, also partially visible around eyes. Antennae with scape more than 5 times longer than wide, slightly curved on proximal third, regularly thickened from base to apex which is curved at basal third, funicle less than 7 times longer than wide, segment 1 of funicle clavate and more than twice longer than wide, second shorter but still obviously longer than wide, 3 to 7 subquadrate, all wider than long, seventh the broadest (width/length ratio 1.19) and about as wide as the first; club oval, 0.54 as wide as long, three-segmented and densely covered with short setae. Prothorax nearly as long as wide, strongly convex, widest slightly before the middle, disc strongly and irregularly sculptured by large deep punctures merged with smaller shallower ones bearing a long recumbent seta, interspaces between punctures matte, microreticulate, the centripetal setae inserted in smaller punctures on average less than 3 times longer than the average diameter of the larger points (average length 0.07 mm), strongly inclined. Elytra oblong elongate, oval, narrower at base than maximum width of prothorax, twice longer than their overall width (width/ length ratio 0.50), subparallel sides regularly convergent to apex, scarcely and very regularly curved, maximum width at mid length, narrowing apically. Interstriae raised, clearly demarcated by points of striae, with small points whose number is lower than that of the points of striae, each bearing a fairly long (average length 0.07 mm) laterally flattened seta almost curved and slihgtly raised on elytral surface (angle with elytral surface 5–20°), some of those setae on elytral apex spatulate and recumbent on elytral surface. Aedeagus slighly curved, sclerotisation of sides broadened in basal half, sides parallel from base to mid length, with sides convergent medially and shortly subsinuate at anterior third, with abruptly strongly curved triangularly shaped apex; lamella drop-shaped, with partially covered sides, centrally raised.
Female genitalia and variabilty. Spermatheca with nodulus not broadened and long cornu. Other specimens differ from lectotype only slightly for size and for the normal differences found in ♀♀: elytra not distinctly more stubby and with sides very slightly arched, inner margin of tibiae more weakly bisinuate, anterior tibiae not curved inwards at apex.

Affinities. Described as a subspecies of S. gestroi, this species is distinguished by different shape of the apex of aedeagus, sharper and not abruptly strongly curved in S. gestroi (Fig. 1 F), the very short funiculus, the much more raised setae on elytral intervals, characters already pointed out by Solari & Solari (1923) in the original description. Solariola hirtula stat. nov. differs from S. fraterna n. sp. by the pronotal shape and very short and compact funiculus.
Ecology. Specimens were collected sifting leaves in a mixed forest of Castanea sativa L. and Quercus ilex L.
