Diagnosis.
A large size
Solariola
(TL: 3.00–4.00 mm; BL:
2.55–3.40 mm
) belonging to the
doderoi
group with quite slender body shape. Within the species group, it is easily recognisable by brownish cuticle and for the less slender body shape. Rostrum quite elongate (RL:
0.50–0.55 mm
, RW:
0.35–0.40 mm
, RL/RW: 1.38–1.43). Mesorostrum carinae divergent to sides. Forehead convex (FW/MW: ratio 2.20–2.42). Mesorostrum and submentum covered by yellowish, compact and elongate pappolepida. Antennae elongate and thin (SL:
0.65–0.75 mm
, FL: 0.85–1.00 mm, SL/FL: 0.75–0.76). Pronotum slightly elongate (PL:
0.75–0.90 mm
, PW:
0.70–0.85 mm
, PL/PW: 1.06–1.07) with many echinopappolepida at base. Elytra sub-parallel to sides, dorsally vaulted (EL:
1.91–2.40 mm
, EW:
1.05–1.30 mm
, EL/EW: 1.82–1.85).
