Type locality. Calabria, Reggio Calabria, Gerace.

Diagnosis. A medium sized Solariola with elytral setae curved and strongly raised on elytral surface (angle with elytral surface up to 45°), wide prothorax with strongly rounded sides, long antennal funicle with large strongly clavate first funicular segment and long club, peculiar spermatheca.

Holotype. ♂, with the following labels: 1) Gerace, Calab[ria]. [leg.] Paganetti , Calabria [white, printed]. 2) Type var. b [white printed] ♂ Solari Boll. Soc. E. it. 1923 [white handwritten]. 3) Solariola fraterna Baviera, 2013 HOLOTYPE. [red printed] ( MSNM).

Paratypes. 2 ♀♀, same holotype data and the following label: Solariola fraterna Baviera, 2013 PARATYPE. [red printed] ( MSNM, GOS)

Others Specimens. 1 ♀, Gerace, 200 m, vaglio olivo, N 38°15.255' E 016° 13. 503', Leg. Bellò C.; 1 ♀, Calabria, Aspromonte, 1905, Leg. Paganetti ( DEI, CBA).

Holotype description. Body length 2.98 mm, maximum width of elytra 0.94 mm. Rostrum very slightly wider than long (width/length ratio 1.06), confusedly and somewhat wrinkled, with wide furrow, subparallel rostral carinae weakly convergent at base and at apex of rostrum. Underside of rostrum densely covered under the scrobe by whitish-yellowish spatulate setae, also partially visible around eyes. Antennae with scape more than 5 times longer than wide, slightly curved at proximal third, regularly thickened from base to apex, funicle almost 9 times longer than wide, segment 1 of funicle strongly clavate, less than twice longer than wide and wider than all the others, segment 2 shorter and obviously longer than wide, 3 to 6 subquadrate and wider than long, 7 slightly longer than wide (width/length ratio 0.94) and longer than the four preceding ones; club three-segmented, oval, more than twice long its width (width/length ratio 0.46), densely covered with short setae. Prothorax nearly as long as wide (width/length ratio 0.98), strongly rounded on sides, widest at middle, disc strongly and 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, the strongly inclined centripetal setae inserted in smaller punctures which are on average less than 3 times the average diameter of the larger points. Elytra oblong elongate, oval, narrower at base than maximum width of prothorax, twice long their overall width (width/length ratio 0.52), subparallel sides regularly convergent to apex, scarcely and very regularly curved, maximum width at mid length, narrowing apically. Strial punctures almost square, each bearing a short seta as long as, or slightly less, than average diameter (≤ 0.03 mm) of punctures, the punctures of first two striae more widely separated than others. Interstriae flat, clearly demarcated by points of striae, minutely punctured, points lower in number than those of striae, each bearing a fairly long (average length 0.07 mm) almost curved laterally flattened and much raised (angle 15–45°) setae, some of those setae on elytral apex are spatulate and recumbent on elytral surface. Aedeagus moderately curved, sclerotisation of sides broadened on basal half, sides parallel from base to midlenght, convergent medially, shortly subsinuate on anterior third, with triangularly shaped apex regularly curved; lamella drop-shaped, free on sides, centrally raised.

Female genitalia and variabilty. Spermatheca with broadened nodulus and narrow cornu with curved apex. Paratypes differs from holotype only in 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.

Distribution. Known only from the type locality ( Fig. 12 View FIGURE 12 ).

Affinities. A medium sized Solariola , previously described as S. gestroi “var. b.” by Solari & Solari (1923), similar to S. gestroi , S. hirtula and S. vitalei , differing from the first two species by the more raised setae on elytra, wide rounded prothorax and distinctly longer than wide antennal club, and from the last species by the aedeagus apex shape and rostral carinae weakly convergent at base and at apex of rostrum.

Ecology. Unknown.
