Types
are 88 (

and

), genitalia of 19 (

3 females
.
Holotype
male: Length:
3.10 mm
. Rather elongate, elytra clearly longer than wide, subparallel sided. Dorsal vestiture of imbricate, golden brown scales and almost flattened short pale spatulate setae; paler small markings on disc of both elytra and pronotum.
Rostrum subquadrate, subparallel sided. Epistoma and plate inconspicuous; pterygia evident; clypeus slightly convex, with longitudinal depression not continuing on frons; frons almost twice as wide as clypeus between antennae. Eyes small, moderately convex. Antennal scape more robust than funicle, curved at basal third and progressively thickening towards apex; first six funicular segments with clubbed setae; first segment shorter than combined length of following two, second slightly longer than third, segments 4–7 pearl-shaped; club short, fusiform and with first segment widely conical.
Pronotum almost as long as wide (length:
0.78 mm
, width:
0.80 mm
), sides sinuate, disc with punctures usually hidden by scales.
Elytra rather elongate (length:
2.40 mm
, width:
1.65 mm
), subcylindrical, disc almost flat, humeri short, round and slightly prominent. Striae inconspicuous, catenulate, interstriae feebly convex.
Legs short and robust; femora clubbed, edentate; tibiae straight, external margin of apex of protibiae blunt, internal margin devoid of spines but with apical mucro; protarsi short and robust, third joint shortly bilobed, onychium curved, claws short and fused at base.
Apex of aedeagus sharp (
Fig. 66
).
Paratypes

. Length: mm 3.10–3.90.
Distribution
: Known only from the
type
locality.
Etymology
: From the name of the ancient Greek town of ‘Himera’, near the present-day Termini Imerese.
Ecology
: Adults have been sifted from the leaf-litter of an olive grove on a moist clay soil. They have been found from late winter to early spring, and were not present when the soil became dry. The new species has been collected together with an unidentified species of
Dolichomeira
Solari, 1955
, members of which usually appear in winter.
Reproduction
: Possibly amphigonic. It is noteworthy that only
4 males
out of
88 specimens
have been found. Further research is needed to rule out if we are faced with two species: one amphigonic and one parthenogenetic.
