Hylobius huguenini Reitter, 1891: 97 (description).
Hylobius huguenini – Stierlin 1898: 298 (faunistic catalogue). — Dalla Torre & Schenkling 1932: 16 (World Catalogue). — Germann 2010: 112 (faunistic checklist). — Germann 2011: 160 (supplement to faunistic checklist).
Remark
The type specimen is in a relatively good condition, the tarsal segments 2-5 of the right hind leg are missing as well as the onychium of the left fore leg. The specimen is slightly immature; this explains its light reddish-brown colour.

Redescription
COLOUR. Body, head, antennae and legs reddish-brown (see above).
VESTITURE. Body, head and legs covered with elongated, oval, yellowish scales of variable width. Tips of broader scales truncated. Frons covered with broader scales. Scarcely standing scales restricted to first fifth of rostrum. Pronotum with broader scales forming lateral bands at each side just before humeral calli of the elytra. Surrounding scales thinner. Elytra with broader and thinner scales patchily arranged, and forming short bands at base of the 3 rd and especially 5 th interstriae. Broader scales are denser just behind second half of elytra, forming a diffuse transverse banding. Scutellum very densely covered with overlapping whitish broader scales.
HEAD. (Fig. 1E) Globular, rostrum 3.5 times as long as wide, eyes oval and flat. Interocular distance half as wide as base of rostrum. Rostrum narrowest in its middle, widened to apex to about the size at base. Rostrum striate and weakly punctate on its first half; only faintly punctate and glossy towards apex. Antennae inserted after last third of rostrum; scrobes from the anterior margin of the eyes apicalwards. Scrobes visible from above from the middle of the rostrum to the apex. Antennal scape reaching base of rostrum. Funicular segments as follows: (L/W): 1 st: 2.3, 2 nd: 2.1, 3 rd: 1.2, 4 th: 0.9, 5 th and 6 th: 0.7 and 7 th: 0.8, club oblong oval.
PRONOTUM. (Fig. 1A, C) Transverse (L/W = 0.7), widest just behind the middle, strongly constricted towards fore margin, densely tuberculate and transversely wrinkled, carinate in the middle, tubercles glossy. Slightly curved in lateral view. Base weakly sinuate, bulged towards scutellum.
ELYTRA. (Fig. 1A, C) Elongate (L/W = 1.8), parallel sided. Base sinuate. Shoulders well pronounced, slightly convex at disc in the middle. Elytra strongly constricted before their last fifth, therefore convex on each side before elytral declivity; apex flattened in lateral view. Striae linear and regularly punctate, interstriae about as wide, convex and glossy. Striae and interstriae weakly blurred by transverse wrinkles.
LEGS. Strong, all femora strongly dentate, tibiae sinuate at inner side, apex with long curved uncus at inner angle. Tips of tibiae in-and outside (ventrally and dorsally) with apical combs, bristles light brown; dorsal row of the apical comb of hind tibiae composed of more than two bristles in parallel. Four visible tarsal segments, 1 st segment 1.5 times longer than 2 nd, 3 rd of about the same length, twice as wide, 4 th segment tiny, 5 th reaching twice as far as 3 rd. Claws simple.
ABDOMEN. (Fig. 1G) Five ventrites, process of first ventrite broadly rounded with tuberculiform tip.
FEMALE GENITALIA. Ventrite 8 with apodeme as long as plate, distinctly constricted before plate. Plate broad, feebly sclerotized, V-shaped, setose at apex. Spermatheca with very long and straight nodulus, cornu short and very strongly bent towards nodulus (Fig. 2H, J). Ovipositor with broad styli (Fig. 2G).
