Type locality. Campania, Salerno, Vallo Lucano, Novi Velia, Gelbison Mount, 950m (Fig. 252).
Diagnosis. A small–medium size Solariola (TL: 2.8 0–3.20 mm; BL: 2.20–2.60 mm) belonging to the gestroi group with more robust body shape. Within the species group, it is easily recognisable by brown–blackish cuticle and the stubby body more robust with ratio: EL/EW 1.75–1.80. Rostrum short (RL: 0.50–0.55 mm, RW: 0.35–0.40 mm, RL/RW: 1.37–1.43). Mesorostrum carinae divergent 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: 0.50–0.60 mm, FL: 0.75–0.85 mm, SL/FL: 0.71–0.67). Pronotum as long as wide (PL: 0.70– 0.70 mm, PW: 0.70– 0.70 mm, PL/PW: 1.00–1.00) without echinopappolepida at base. Elytra oblong, sub-oval to sides, dorsally little vaulted (EL: 1.65–1.90 mm, EW: 0.95–1.06 mm, EL/EW: 1.75–1.80) with elytral setae short, recumbent.

Distribution. See Figs. 222, 222a. Italian endemic. Known from Salerno, Vallo Lucano, and surroundings Novi Velia type locality on Gelbison Mount at 900–1000 meters of elevation.
Etymology. This species is named after Sbordoni (Valerio) international fame zoologist, friend and colleague of one of us (Osella).
Ecology and Phenology. S. sbordonii specimens were collected by Winkler or Berlese extractors from soil obtained sifting the leaf litter of Castanea and Quercus in October. In May, Our collections in the type locality gave negative results.
Main soil type. Dystrict Cambisol (European Soil Data Centre; Panagos et al. 2012).
Reproduction. Probably amphigonic. Male Unknown.
Associated species. Sympatric with Heteromeira curvisetis Pierotti, 2011 and Aparopion suturidens Reitter, 1891.
