Description
Body (Fig. 5) unicoloured, reddish-brown, maxillary palpi light brown, length 2.87–3.1 mm.
Head elongate, about 1.10 times longer than wide, slightly longer than pronotum; median sulcus visible on rostrum, on vertex reaching level of vertexal foveae. Genae with weak protuberance, covered with erected, dense golden setae.
Antennae about 2.15 mm long (Fig. 13); scapes long, about 3.4 times longer than pedicels; pedicels about 1.18 times shorter than antennomeres III, antennomeres V and VI as long as pedicels; VII 1.25 times shorter than VI; antennomeres VIII about 1.27 times longer and distinctly wider than VII; antennomeres IX about 1.5 times longer than wide, about the same length as terminal antennomeres, in male with deep ventral concavity on apical half terminating with nail-shaped protuberance, in female unmodified; antennomere X quadrate, 1.5 times shorter than IX; terminal antennomeres 1.6 times as long as X and about 1.5 times longer than wide.
Pronotum about as wide as long, wrinkly, evenly rounded before lateral foveae; lateral and median setose foveae well-defined; median sulcus thin.
Legs long and slender; protrochanters with large apical spine; profemora with long spine in middle of its length; mesotrochanters at apex with two minuscule (male) or two strong (female) and one minuscule spine; mesofemora with minuscule spine at basal third.
Abdomen slightly wider than elytra; first visible abdominal tergite (IV) finely punctate, with dense and long golden setae, about 4 times longer than second visible tergite (V); basal carinae very short, distance between carinae 0.53 of maximal tergal width. Aedeagus (Fig. 23) 0.61 mm long; median lobe weakly narrowed apically, with long and relatively narrow apical lobe; endophallus with one bifid spine and two small lamellas; lamellas finely dentate on the apical part; parameres long, overlapping apical lobe, enlarged at apex.
Differential diagnosis
Lasinus mikado is close to Lasinus monticola and Lasinus yakushimanus by the presence of a nail-shaped protuberance on antennomeres IX, it differs from both by the presence of a deep concavity on antennomeres IX and by the shape of aedeagus.
Etymology
The name is derived from the Japanese word – „mikado“, meaning the Emperor of Japan.
Distribution
Japan (Hokkaido, Honshu, Shikoku), Russia (Kuril Islands).
Remarks
The original type series of Lasinus spinosus in the Sharp collection is in fact a mix of Lasinus spinosus and Lasinus mikado sp. n.
