Holotype
female. Length:
4.85 mm
. Robust, oval-shaped, elytra longer than wide. Dorsal vestiture of imbricate, earth-brown and brown scales and almost erect brown rather thin setae; paler small markings are on disc of both elytra and pronotum.
Rostrum subquadrate, sides converging towards apex. Epistoma concave with bulging margins; pterygia inconspicuous; clypeus in front wider than at base, with a longitudinal depression not continuing that on frons. Eyes slightly convex. Antennal scape just slightly more robust than funicle, slightly curved and progressively thickening towards apex; first 4 funicular segments with clubbed setae; first segment as long as than the combined length of the following two, second twice as long as third, segments 4–7 pearl-shaped; club elongate, fusiform and with the first segment widely conical.
Pronotum slightly transverse (length: 1.00 mm, width:
1.20 mm
), sides sinuate, disc with punctures usually hidden by the scales.
Elytra oval (length: 3.00 mm, width: 2.00 mm), disc slightly convex, humeri short, round and slightly prominent. Striae inconspicuous, catenulate, interstriae feebly convex.
Legs quite short and robust; femora clubbed, edentate; tibiae short, almost straight, external margin of protibiae blunt, internal one devoid of spines; protarsi short and robust, third joint shortly bilobed, onychium curved, claws short and fused at base.

Paratypes
: Only females. Specimens of Castiglione are bigger (mm 4.20–5.00) of Malabotta ones (mm 3.70– 4.20). No significant differences were observed between the
holotype
and
paratypes
. Length: 3.70–5.00 mm.
Distribution
: Northern and central Sicily.
Etymology
: Named after the hedgehog (
Erinaceus europaeus
L., 1758) in reference to the erect thin setae on the dorsal surface.
Ecology
: This species prefers cool shadowy places, and has been found sifting under
Fagus
sp.,
Olea
sp.,
Rubus
sp.,
Quercus
sp.,
Fraxinus
sp.,
Smilax
sp. Adults occur in spring and/or autumn, according to the elevation, with diapause in summer or in winter.
Pseudomeira erinacea
is a parthenogenetic species collected at Castiglione di Sicily together with
P. vitalei
; at Malabotta, Marineo and Ficuzza with
Heteromeira neapolitana
; at Pioppo with
Dolichomeira dubia
Pierotti & Bellò, 1994
and at Castelvetrano with
Dolichomeira
sp..
Reproduction
: Parthenogenetic.
Notes
: Only detailed morphological, ecological and molecular studies have allowed for the recognition of this cryptic species, incorrectly indicated from some localities as
P. s o l a r i i
by
Péricart (1963)
and
Pierotti & Bellò (1994)
