Diagnosis.
A medium-size species (3.40–4.00 mm) belonging to the
adrianae
group with short sub-parallel elytra (length/width ratio: 1.63–1.65) and body shape sub-cylindrical. Within the species group, it is recognisable by elytral declivity with raised setae (30°–45°), pronotum less transverse (length:
0.77–0.90 mm
, width: 0.80–1.00 mm, ratio 0.90–0.96), mesorostrum with clavate setae and protibia with only two acute spines on inner edge. Elytra slightly vaulted dorsally (length:
2.20–2.60 mm
, width:
1.35–1.58 mm
, ratio 1.63–1.65), clothed by imbricate brown-silvery scales and and short silvery setae clavate.

Holotype
.
Female. Total length:
3.60 mm
. Body shape slender and subcylindrical. Dorsal vestiture with imbricate, brownish-silvery scales with metallic sheen; short, raised, clavate setae on pronotum as on elytra (angle with elytral surface 30°–45°).
Rostrum covered by silvery-brown scales, transverse (length/width ratio 0.69), sub-parallel to the sides. Pterygia obvious. Epistome absent. Mesorostrum slightly concave, anteriorly with about ten thin, curved, semierect setae. Vertex wide and convex (vertex width / mesorostrum width: ratio 2.00) with clavate and semi-erect or erect setae. Interocular space with fovea. Lateral and spherical eyes protruding from outline of head. Antenna robust and quite short with long, raised, silvery, widened setae. Antenna with ratio 0.75 (scape length:
0.75 mm
, funicle length: 1.00 mm). Scape clubbed, slightly more robust than funicle, curved at the first third. Funicle segments including club, relative lengths as follows: 11.5.3.3.3.3.3.15; segments 1–6 with clavate-widened setae; segments 4–7 pearl-shaped. Club at least twice wider than funicle, fusiform with suture between first and second segment visible.
Pronotum clothed with silvery-brown scales, transverse (length:
0.82 mm
, width:
0.90 mm
, ratio: 0.91), slightly sub-hexagonal, sinuate at the sides, wider in the middle with clavate, golden silvery recumbent setae. Punctation usually covered by scales. Scutellum small but obvious.
Elytra vaulted, covered by golden silvery scales, sub-cylindrical with suture quite flat (length:
2.40 mm
, width:
1.45 mm
, ratio: 1.65), wider at the middle. Humeri short and rounded. Elytral declivity with raised setae (30°–45°). Punctation of striae, shallow, catenulate and impressed. Interstriae flat, with clavate, long, golden silvery, raised or semi-erect setae.
Legs short and robust covered by silvery-brown scales and rather short, clavate, silvery-golden setae. Femora clubbed. Protibia with two acute spines on inner edge, with mucro evident on inner apical angle. Protibia not sinuous on inner edge, metatibia and mesotibia straight in side view.
Tarsal segment 1 short, conical; segment 2 short and transverse; segment 3 shallowly bilobed; all segments with thin golden setae. Onychium curved, robust and quite short.
Female genitalia
. See Figures: spermatheca (
Fig. 71
), sternite VIII (
Fig. 110
). Genitalia were examined in six specimens.
Paratype
variability.
Paratypes
(all females) are similar to the
holotype
and differs only in size.
Distribution.
See
Fig. 139
. Italian endemic. Known from Sicani Mountains only near
type
locality Bisacquino.
Etymology.
Named from Latin word
sicelidis
(Sicilian)
.
FIGURES 12–12f.
Dodomeira
sicelidis
Bellò
& Baviera sp. n. holotype ♀ from “Bisacquino, Palermo”: 12—habitus dorsal view (scale bar: 1 mm); 12a—habitus, lateral view; 12b—pronotum and rostrum, lateral view; 12c—pronotum, dorsal view; 12d–—elytral vestiture; 12e—funicle and club; 12f—spermatheca.
Ecology and Phenology.
Collected by Berlese and Winkler extractors from soil obtained sifting the leaf litter on clay soil, of an olive grove in March and April, at 700–800 meters.
Collections in the summer months gave negative results suggesting that adults of the
Dodomeira sicelidis
are absent during this time.
Main soil
type
.
Vertic-Cambisol
(European Soil Data

Reproduction.
Probably parthenogenetic. Species known from eighteen females.
Chorological relationships.
Sympatric with
Dolichomeira
sp., genus usually wintry, at Bisacquino.
