; BL: 2.10–3.00 mm) belonging to the
paganettii
group with slender body shape. Within the species group, it is recognisable by sub-parallel elytra with short and raised setae, pronotum as long as wide, rostrum very robust and short (RL:
0.40–0.50 mm
, RW:
0.30–0.40 mm
, RL/RW: 1.25–1.33). Mesorostrum carinae slightly divergent to sides. Forehead convex (FW/MW: 2.00–2.00). Submentum with short, whitish-yellowish pappolepida. Antennae with short scape and elongate funicle (SL:
0.55–0.65 mm
, FL:
0.65–0.90 mm
, SL/FL: 0.72–0.84). Pronotum as long as wide (PL:
0.60–0.85 mm
, PW:
0.60–0.85 mm
, PL/ PW: 1.00–1.00) without echinopappolepida at base. Elongate, sub-parallel elytra, dorsally vaulted (EL:
1.55–2.20 mm
, EW:
0.77–1.10 mm
, EL/EW: 2.00–2.01) with thin, short, raised setae.

2.80 mm
, BL:
2.40 mm
). Red-brownish cuticle.
Rostrum short and robust (RL:
0.45 mm
, RW:

holotype ♂ from “Cinquefrondi”: 41—habitus dor- sal view (scale bar: 1 mm); 41a—habitus, lateral view; 41b—rostrum, lateral view; 41c—base of the elytra; 41d—elytral declivity; 41e—details rostrum, pronotum, funicle and club.
FIGURE 41. (Continued)
FIGURE 41. (Continued)
Legs short and robust with clubbed femora. Protibia with seven acute spines on inner edge and an evident mucro on inner apical angle. Protibia 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.

Female genitalia.
See Figs: spermatheca

Sexual dimorphism.
Males can usually be recognized by their smaller size, slender appearance, more rounded humeri, legs stronger with a more noticeable apical mucro, and ventrites 1 and 2 slightly hollowed.
Paratypes
variability.
Paratypes
, sexual dimorphism excluded, are similar to the
holotype
but differs in size.
Distribution.
See Figs. 223, 223a. Italian endemic. Known from Aspromonte Mountains near Cinquefrondi locality at 500–600 meters of elevation.
Etymology.
Named from the Greek word “Pentáphyllon”, hypothetic ancient name of “Cinquefrondi”.
