Description.
Body unicoloured, reddish-brown, maxillary palpi yellow dark, length 2.70-3.10 mm.
Head elongate, about 1.08 longer than wide, slightly shorter than pronotum; median sulcus shallow, reaching level of vertexal foveae. Genae with weak protuberance, covered with erected, dense golden setae.
Antennae about 1.8 mm long (Fig. 18); scapes long, about twice longer than pedicels; pedicels 1.22 times longer than antennomeres III; antennomeres IV as long as wide; antennomeres V slightly longer than wide; antennomeres VI about 1.33 times longer than wide; antennomeres VII and VIII slightly longer than wide; VII 0.88 times longer than wide; VIII 0.9 times longer than wide; IX about 1.26 times longer than wide, in male with short tubercles in apical ventral part, in female unmodified; antennomeres X about 1.33 longer than wide; terminal antennomeres about as long as wide.
Pronotum slightly longer than wide, wrinkly, evenly rounded before lateral foveae; lateral and median setose foveae well-defined; median sulcus thin and deep.
Legs long and slender; protrochanters with large apical spine; profemora with long spine in middle of its length; mesotrochanters at apex with one (male) or three (female) spines; mesofemora with minuscule spine at basal third.
Abdomen slightly wider than elytra; first visible abdominal tergite (IV) finely punctate, with sparse golden setae; carinae very small, distance between them 0.48 of maximal tergal width. Aedeagus (Fig. 28) 0.61 mm long; median lobe weakly narrowed apically; endophallus with two spines and two lamellas; ventral spine large, enlarged in middle, acute at apex; dorsal spine slender, acute at apex; dorsal lamella small, finely dentate on apical part; ventral lamella large; parameres very short and slender, not reaching apical lobe.
Differential diagnosis.
Lasinus saoriae strongly resembles Lasinus amamianus from which it differs essentially by the shapes of the antennae and the aedeagus.
Etymology.
The specific epithet is dedicated to Saori Takeuchi (Japan), a family friend of the first author.
Distribution.
Japan (Okinawajima Island).
