(Figs 25, 25a, 25b, 25c, 25d, 25e, 45j, 71, 71 ’, 114, 157, 200) http://zoobank.org/ urn:lsid:zoobank.org:act: 0DEC590B-5113-4F34-B439-7F63CA966FDE
Type locality. Calabria, Reggio Calabria, Aspromonte Mountains, Palmi, (Fig. 251).
Diagnosis. A small size Solariola (TL: 2.2 0–2.85 mm; BL: 2.10–2.30 mm) belonging to the gestroi group with more robust body shape. Within the species group, it is recognisable by red-brownish cuticle, elytra sub-oval to sides, pronotum longer than wide, legs short and robust. Rostrum stubby (RL: 0.35–0.45 mm, RW: 0.25–0.35 mm, RL/RW: 1.29–1.40). Mesorostrum carinae sub-parallel to sides. Forehead convex and wide (FW/MW: 2.00–2.00). Submentum with whitish–yellowish, flattened, and short pappolepida. Antennae with scape and funicle quite elongate and thin (SL: 0.45–0.55 mm, FL: 0.60–0.70 mm, SL/FL: 0.75–0.83). Pronotum longer than wide (PL: 0.55– 0.70 mm, PW: 0.50–0.65 mm, PL/PW: 1.08–1.10) without echinopappolepida at base. Elytra elongate, sub-oval to sides, dorsally rather flat (EL: 1.25–1.75 mm, EW: 0.73–0.93 mm, EL/EW: 1.81–1.88) with elytral setae elongate, semi-erect.
Type series. Holotype female with following labels: ♀ [w, p] / Calabria (RC): Palmi, fogliame castagno, 27. III. 1972, leg. F. Bernini [w, hw] / Solariola [w, hw] / Museo Civico di Genova / [w, p] / Collezione Cesare Bellò, Castelfranco Veneto [g, p] / Solariola poggii Holotype det. Bellò, Osella & Baviera, 2018 [r, p] / esemplare fotografato by Francesco Sacco [y, p] (MSNG).
Paratypes. Six specimens (1 male and 5 females) with following labels: Calabria (RC): Palmi, fogliame castagno, 27. III. 1972, leg. F. Bernini [w, hw] / Solariola [w, hw] / Museo Civico di Genova / [w, p] (3 females, MSNG); Calabria (RC): Palmi, fogliame castagno, 27. III. 1972, leg. F. Bernini [w, hw] / Collezione Cesare Bellò, Castelfranco Veneto [g, p] (CBA; CBE). All with label: Solariola poggii paratype det. Bellò, Osella & Baviera, 2018 [r, p].
Holotype description. Male. See Figs 25, 25a, 25b, 25c, 25d, 25e. Elongate–oval body (T L: 2.50 mm, BL: 2.15 mm). Red-brownish cuticle.
Rostrum stubby (RL: 0.40 mm, RW: 0.30 mm, RL/RW: 1.33), conical to sides with pterygium expanded. Epistome absent. Mesorostrum carinae sub-parallel sides. Submentum with some pappolepida, yellowish–whitish, short and not visible around mesorostrum. Interocular pit visible. Forehead convex and wide (FW/MW: 2.00). Vestigial eyes convex, not small and well visible.
Antennae with scape and funicle quite short and thin (SL: 0.50 mm, FL: 0.60 mm, SL/FL: 0.83); AS ratio: 5.5.4.3.3.3.3.10. 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, oval, in length twice the width, densely covered by thin setae.
Pronotum elongate (PL: 0.60 mm, PW: 0.55 mm, PL/PW: 1.08), wider in the middle and without echinopappolepida at base. Scutellum visible.
Elytra oval-elongate and sub-parallel to sides, dorsally sub-flat (EL: 1.50 mm, EW: 0.83 mm, EL/EW: 1.81), wider at middle with slightly convex suture. Humeri rounded. Striae with 12–13 punctures, catenulate. Interstriae slightly convex, with thin and elongate setae semi-erect. Elytral declivity<60 degrees.
Legs short and robust with femora clubbed. Protibia with eight acute spines on inner edge and an evident mucro on inner apical angle. Protibia slightly sinuous on inner edge and slightly curved 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. 71; apex of penis Fig. 71 ’; IX sternite Fig. 114.
Female genitalia. See Figs: spermatheca Fig. 157; VIII sternite Fig. 200.
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 only from Palmi locality, town located at the coastal ridge of the Aspromonte massif.
Etymology. This species is named after our friend and colleague Poggi (Roberto), Honorary Curator of MSNG, eminent specialist in Coleoptera Staphylinidae Pselaphinae, in appreciation and gratitude for his collaboration in our study on Peritelini …
Ecology and Phenology. S. poggii specimens were colleceted by Berlese extractors from soil obtained sifting the leaf litter of a chestnut grove in March.
Main soil type. Eutric Cambisol (European Soil Data Centre; Panagos et al. 2012).
Reproduction. Amphigonic.
Associated species. Unknown.
