Prosternum ( Fig. 7 K) convex; anterior color bent antero-inferiorly and roundly margined, sub-equal in length to anterior apex of hypomera; posterior process bent beyond procoxal cavities and then expanded laterally, ventral surface slightly convex in lateral view ( Fig. 7 L); procoxal cavities narrowly open posteriorly; pronotosternal sutures double, nearly straight, anterior portion ( Fig. 7 M) distinctly furrowed and expanded ventrally; hypomeron shallowly impressed anteriorly, with a distinct emargination near posterior apex ( Fig. 7 N). Scutellum ( Fig. 7 J) pentagonal, flat, 1.4 times longer than wide, anterior margin 0.75 times narrower (21:28) than the widest point beyond middle; lateral sides parallel to one third and then broadly and roundly expanded; posterior margin semi-elliptical; pubescence distinctly long. Mesocoxal cavities ( Fig. 7 O) broadly connected with mesoepimeron, but distinctly narrowly connected with mesoepisternum. Metasternum moderately convex; median longitudinal suture incomplete; hind coxal plates ( Fig. 7 P) widest at insertion of trochanter, outer margin slightly convergent to anterior two thirds and then suddenly narrowed laterally. Legs slender, tibia and claws ( Fig. 7 S) simple. Elytra ( Fig. 7 Q) sub-cylindrical, 2.3–2.6 times as long as wide, slightly wider than pronotum, widest at humeral angles, parallel-sided on posteriorly two thirds and then gradually rounded to posterior third, sutural line weakly elevated with a small spine at apex; base weakly concave along anterior edges; striae ( Fig. 7 Q) punctate, distinct; strial intervals feebly convex, densely punctate. Abdomen with each margin of sternites entirely and weakly crenulate ( Fig. 7 T); sternite 7 ( Fig. 7 R) semi-oval, 1.7 times as wide as long, punctures becoming denser and larger posteriorly. Aedeagus ( Fig. 8 A–B) conically shaped, 3.15 times (23:7.3) as long as wide; median lobe slender, gradually narrowed to apex, exceeding apices of parameres, 3.0 times (13.7:4.5) longer than basal struts; parameres narrowing to apex, lateral margins slightly sinuate at middle and then slightly arched, inner margins straight, with lateral subapical barb expanded triangularly; lateral subapical barb ( Fig. 7 B) distinctly elongated, 1.84 times (3.5:1.9) as long as wide, with 5–6 long setae on dorsal surface; basal piece quadrate, 1.26 times as long as wide, 0.4 times (9.2:23) of total length of aedeagus.

Female ( Fig. 1 F). Length 9.5–12.8 mm, width 2.3–3.2 mm, larger, stouter than male; antennae shorter than male, antennae exceeding beyond of hind angles of pronotum by half of 11th segment, 2nd segment a little longer than 3rd (about 1.06–1.13 times), the combined length of 2nd and 3rd segments distinctly longer (1.24–1.30 times) than 4th; pronotum more convex and swollen than male, lateral margins of pronotum invisible medially; lateral margins of elytra generally parallel-sided from humeral angles, then widest before maculae. Reproductive organs ( Fig. 8 C): ovipositor sub-triangular, with styli; vagina elongate, rather stout; uterus subcylindrical, broader at base of BC than at base of vagina, with small colleterial glands, lacking sclerotised structures; bursa copularix sac like with a small accessory gland, and then cylindrically elongate with a short accessory gland and a long tubular extension.

Reference species. Limoniscus kraatzi nihonicus ( Kishii, 1966) : female, Otari onsen, Otari-mura, Nagano Pref. N361546-3652405, E13759038-13758459, H 1096-1130, Japan. 26. VI. 2006. K. J.

Remarks. Candèze (1879) described the species from Amur in Russian Far East. Miwa (1928) reported the species in Korea for the first time based on a male specimen collected from Kôryô (= Gwangreung sited in Pocheon, GG). This nomino-typical subspecies, widely distributed from the Primorsky in Russian Far East to Jilin in eastern China and the Korean Peninsula, is distinguishable from the subspecies L. kraatzi nihonicus ( Kishii, 1966) in Japan by the size and density of punctures on the pronotum and the shape of the scutellum ( Kishii, 1966: 47). Taxonomic and biological aspects of this species were identified by Ôhira (1984). He particularly pointed out the color variation of the pubescence, from grayish to golden yellow, and the shape variation in the elytral maculae. Ôhira et al. (2006) provided brief information on the Russian population of the species.

Distribution. Korean Peninsula, Russian Far East, China (Jilin) ( Ôhira et al. 2006, Cate, 2007)
