Diagnosis. Male: BL = 5.5–7.6 mm. Body black; elytra ochreous; antennae dark brown, pronotum and scutellum black; legs black except yellowish brown basal half of each femur; abdominal ventrites I–IV black and V yellowish brown, but sometimes lateral margin of III and IV yellowish. Head and pronotum sparsely covered with dark recumbent short hairs intermixed with sparse long pale hairs; elytra furnished with moderately dense pale yellowish slanted hairs which are nearly as long as space between punctures; ventral surface bearing rather dense long thin whitish hairs.

Head and pronotum bearing moderately dense distinct punctures; antennae rather long, reaching apical third of elytra.

Pronotum distinctly shorter than width across lateral tubercles (PL/PW=0.87).

Elytra parallel-sided, more than twice as long as humeral width (EL/EW=2.14), densely covered with rough punctures of rugged texture.

Endophallus (Type A). Dorsal view: CT swollen, dm cordiform with round ds surrounded by U-shaped lrs; PB parallel sided without inflation; APH swollen distally. Lateral view: CT inflated ventrally; PB tube-like without constriction; APH swollen distally.

Female: BL = 6.4–8.5 mm; PL/PW = 0.89; EL/EW = 2.06. Similar to male but antennae short, reaching middle of elytra; elytra slightly widened from humeri to apical fourth.

Remarks. This is the type species of the genus Lemula . In addition to Japan, it has also been recorded from Russia in spite of no record from northern Japan (Hokkaido). Mikhail Danilevsky (pers. comm.) provided the following comment: “I’ve never seen Lemula from Russian fauna, neither Tsherepanov. He (1979) described imago on the base of a single Japan specimen from Plavilstshikov’s collection. Plavilstshikov (1936) definitely recorded Lemula for Ussuri-land, but without more precise indication of locality and without material. Tsherepanov (1979) just repeated Plavilstshikov’s record, but added Sakhalin without any comments. Same was done by Krivolutskaya & Lobanov ( Tsherepanov 1996). I ( Danilevsky 2014) wrote, that occurrence of Lemula decipiens in Russia is very doubtful.” Based on this information, we exclude this species from the fauna of Russia.

Kano (1927) recorded this species from Musha, Taiwan, and Gressitt (1951) cited this record. But as indicated by Nakamura (1974), it is a doubtful record and the species should be removed from Taiwanese fauna.
