Description

Body bicoloured (Fig. 3), darker brown with more reddish elytra, maxillary palpi yellow, length 2.80–3.30 mm.
Head elongate, about 1.06 times longer than wide and as long as pronotum; median sulcus weakly defined along whole length of head. Genae with triangular, prominent protuberance, covered with erect, dense golden setae (Fig. 6). Antennae about 2.23 mm long (Fig. 12); scapes long, about 4 times longer than pedicels; pedicels shortest, quadrate and as long as IV and V each; antennomeres III about 1.25 times longer than pedicels; antennomeres VI–VII subequal in length; VIII slightly shorter than VII; IX about 1.5 times longer than wide, with apical, nail-shaped protuberance on ventral side in male, in female unmodified; antennomeres X quadrate, 1.25 times shorter than IX; terminal antennomeres 1.5 times longer than X and about 1.5 times longer than wide.
Pronotum slightly longer than wide, wrinkly, evenly rounded before lateral foveae (Fig. 8); lateral and median setose foveae well-defined; median sulcus weakly-defined. Legs long and slender; protrochanters with small apical spine; profemora with long spine before middle; mesotrochanters at apex with two (males) minuscule spines or three (females) spines, median one minuscule; mesofemora with minuscule spine at basal third.
Abdomen slightly wider than elytra, first visible tergite (IV) about 3 times as long as second (V), finely punctate with dense, very short golden setae; basal carinae well-defined but very short, distance between carinae 0.5 of the maximal tergal width. Aedeagus (Fig. 21) 0.66 mm long; median lobe weakly narrowed apically, with short and large apical lobe, curved downwards in middle; endophallus with two spines and one large lamella; dorsal spine large, enlarged in middle to form broad plate, acutely angled at apex, with one small tooth in middle; ventral spine short, acute at apex; lamella large; parameres long, overlapping apical lobe, enlarged apically.

Differential diagnosis

Lasinus monticola is close to Lasinus mikado and Lasinus yakushimanus by the presence of nail-shaped protuberance on the antennomeres IX,butit differs from Lasinus yakushimanus by the shape of the genal region of the head and the pronotum, and it differs from Lasinus mikado by the absence of a deep concavity on antennomeres IX. Lasinus monticola can be readily separated from both species also by the shape of aedeagus.

Distribution

Japan (Honshu, Shikoku, Kyushu).
