Type locality. Sicily, Agrigento, Palma di Montechiaro, 120m (Fig. 240).
Diagnosis. A medium size Solariola (TL: 3.30 mm; BL: 2.70 mm) belonging to the doderoi group with quite slender body shape. Within the species group, it is easily recognisable by brownish cuticle, the short rostrum (RL: 0.40 mm, RW: 0.32 mm, RL/RW: 1.25) and the elongate pronotum (PL: 0.80 mm, PW: 0.70 mm, PL/PW: 1.14). Mesorostrum carinae divergent to sides. Forehead convex (FW/MW: ratio 2.50). Submentum and partially the mesorostrum with thick and elongate pappolepida. Antennae quite elongate and thin (SL: 0.70 mm, FL: 0.95 mm, SL/FL: 0.74). Pronotum very elongate with echinopappolepida at base. Elytra sub-parallel to sides, dorsally vaulted (EL: 1.97 mm, EW: 1.00 mm, EL/EW: 1.97).
Type series. Holotype male with following labels: [genitalia in DHMF] [transparent label] / ♂ [w, p] / Sicilia, Agrigento, Palma di Montechiaro, Olea & Thymus, 1. III. 2013, leg.

Paratype. Unknown.
Holotype description. Male. See Figs 14, 14a, 14b, 14c, 14d, 14e. Quite stubby–cylindrical body (TL 3.30: mm and BL: 2.70 mm). Brownish cuticle.
Rostrum short (RL: 0.40 mm, RW: 0.32 mm, RL/RW: 1.25), conical to sides with expanded pterygium. Epistome absent. Mesorostrum carinae divergent to sides. Submentum covered by yellowish pappolepida, also partially visible around mesorostrum. Interocular pit visible. Forehead convex (FW/MW: 2.50). Vestigial eyes convex and just visible.
Antennae thin and elongate (SL: 0.70 mm, FL: 0.95 mm, SL/FL: 0.74); AS ratio: 8.8.5.4.3.3.4.13. Scape clubbed, more robust than funicle, curved at proximal third and progressively thickening towards apex. Funicle long and quite thin; all antennal segments with thin setae. Club three-segmented, compact-oval, in length twice the width, densely covered by thin setae.
Pronotum elongate (PL: 0.80 mm, PW: 0.70 mm, PL/PW: 1.14), wider at middle and with echinopappolepida at base. Scutellum visible.
Elytra elongate, rounded to sides, dorsally vaulted (EL: 1.97 mm, EW: 1.00 mm, EL/EW: 1.97), wider at middle with convex suture. Humeri rounded. Striae with 15–16 evident punctures, catenulate, large, deep. Interstriae convex with thin setae recumbent and short. Elytral declivity> 60 degrees.
Legs quite short and robust with femora clubbed. Protibia with six spines on inner edge and an evident mucro on inner apical angle. Protibia quite 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. 60; apex of penis Fig. 60 ’; IX sternite Fig. 103.
Female genitalia. Unknown.
Sexual dimorphism. Females are unknown.
Paratypes variability. Unknown.
Distribution. See Figs. 221, 221a. Sicilian endemic. Known only from Agrigento, Palma di Montichiaro locality.
Etymology. Named after Sacco (Francesco), specialist in Apionidae, our colleague, friend, and author of the photos so well illustrating this work, in appreciation and gratitude for his extraordinary collaboration.
Ecology and Phenology. The holotype fo this speies was collected by Winkler extractors from soil obtained sifting the leaf litter on clay soil, of an olive grove in March, at elevations from 150–200 meters. Numerous and repeated collections at the same locality, in the same or in other seasons gave negative results.
Main soil type. Vertic Cambisol (European Soil Data Centre; Panagos et al. 2012).
Reproduction. Amphigonic.
Associated species. Sympatric with Pseudomeira doderoi Solari, 1955.
