(Figs 27, 27a, 27b, 27c, 27d, 27e, 45l, 73, 73 ’, 116, 159, 202) http://zoobank.org/ urn:lsid:zoobank.org:act: 10F38FE8-B450-46DB-AA5B-729AEF244BFD
Type locality. Calabria, Cosenza, Sila Greca Mountains, Bocchigliero, Basilicò Mount, 900m (Fig. 253).
Diagnosis. A small size Solariola (TL: 2.5 0–2.80 mm; BL: 2.05–2.38 mm) belonging to the gestroi group with more robust body shape. Within the species group, it is easily recognisable by reddish orange cuticle, the quite stubby body and the particularly short rostrum. Rostrum particularly short (RL: 0.35–0.42 mm, RW: 0.30–0.35 mm, RL/RW: 1.17–1.20). Mesorostrum carinae parallel to sides. Forehead convex and wide (FW/MW: 2.00–2.00). Submentum with yellowish, flattened, and very short pappolepida. Antennae with scape and funicle quite elongate and thin (SL: 0.50– 0.50 mm, FL: 0.75– 0.75 mm, SL/FL: 0.67–0.67). Pronotum more long than wide (PL: 0.60–0.65 mm, PW: 0.55–0.60 mm, PL/PW: 1.08–1.09) without echinopappolepida at base. Elytra oblong–elongate, sub-oval to sides, dorsally little vaulted (EL: 1.50–1.65 mm, EW: 0.80–0.90 mm, EL/EW: 1.83–1.88) with elytral setae quite short, raised.

Osella [w, hw] / vaglio lettiera farnetto [w, hw] (5 males, 13 females, GOS); Calabria, CS, Sila Greca, monte Basilicò, 900m, 9 X 93, leg. Bellò [w, hw] / Solariola n sp! [w, hw] / edeago (dritto e profilo), antenna, dettaglio punteggiatura pronoto [w, hw] / S. silensis sp. nov. [r, hw] (1 male, GOS). All with label: Solariola tedeschii paratype det. Bellò, Osella & Baviera, 2018 [r, p].
Holotype description. Male. See Figs 27, 27a, 27b, 27c, 27d, 27e. Stubby oval body (T L: 2.50 mm, BL: 2.05 mm). Reddish orange cuticle.
Rostrum quite stubby and particularly short (RL: 0.35 mm, RW: 0.30 mm, RL/RW: 1.17), conical to sides with pterygium expanded. Epistome absent. Mesorostrum carinae parallel to sides. Submentum with some pappolepida, yellowish, short and not visible around mesorostrum. Interocular pit not visible. Forehead convex and wide (FW/ MW: 2.00). Vestigial eyes slightly convex, small, visible.
Antennae with scape and funicle quite elongate and thin (SL: 0.50 mm, FL: 0.75 mm, SL/FL: 0.67); AS ratio: 6.5.4.3.2.3.3.11. Scape clubbed, more robust than funicle, curved at proximal third and progressively thickening towards apex. Funicle segments with elongate and thin setae. Club three-segmented, fusiform, in length twice the width, densely covered by thin setae.
Pronotum more long than wide (PL: 0.60 mm, PW: 0.55 mm, PL/PW: 1.09), wider in the middle and without echinopappolepida at base. Scutellum visible.
Elytra oblong–elongate and sub-oval to sides, dorsally slightly vaulted (EL: 1.50 mm, EW: 0.80 mm, EL/EW: 1.88), wider at middle with slightly convex suture. Humeri rounded. Striae with 11–12 punctures, catenulate. Interstriae slightly convex, with thin and quite short raised setae. Elytral declivity>60 degrees.
Legs short and robust with femora clubbed. Protibia with seven acute spines on inner edge and an evident mucro on inner apical angle. Protibia slightly sinuous on inner edge and straight in side view. Metatibia and mesotibia straight in side view. All tibia with noticeable apical comb. Tarsal segment 1 short, conical; segment 2 short and transverse; segment 3 very bilobed; all segments with thin golden setae. Onychium curved, robust and short with one short claw.
Male genitalia. See Figs: dorsal shape aedeagus Fig. 73; apex of penis Fig. 73 ’; IX sternite Fig. 116.
Female genitalia. See Figs: spermatheca Fig. 159; VIII sternite Fig. 202.
Sexual dimorphism. Males can usually be recognized by their smaller size, slender appearance, more rounded humeri, legs stronger with a more noticeable apical mucro, and ventrites 1 and 2 slightly hollowed.
Paratypes variability. Paratypes, sexual dimorphism excluded, are similar to the holotype but differs in size.
Distribution. See Figs. 222, 222a. Italian endemic. Known from Cosenza, Sila Greca, and Bocchigliero type locality, on Basilicò Mount at 900–1000 meters of elevation.
Etymology. This species is named after our friend and colleague Tedeschi (Michele), in appreciation and gratitude of his valuable collaboration in our study on Curculionidae.
Ecology and Phenology. Collected S. tedeschii by Winkler or Berlese extractors from soil obtained sifting the compact leaf litter of Quercus robur L. in October.
Main soil type. Eutric Cambisol (European Soil Data Centre; Panagos et al. 2012).
Reproduction. Amphigonic.
Associated species. Sympatric with Pseudomeira obscura (A. & F. Solari, 1907) and Aparopion suturidens Reitter, 1891.
