A – male fore leg, ventral view; B – female fore leg, ventral view; C – male hind leg, ventral view; D – female hind leg, ventral view; E – male protibia, dorsal view; F – female protibia, dorsal view; G – male metafemur, dorsal view; H – female metafemur, dorsal view. Scale I: 1 mm for A–D; II: 0.2 mm for E and F; III: 0.2 mm for G and H. Diagnosis. Coloration. Dorsum brown; antennomeres 1–6 and 8 brown; antennomeres 7, 9, 10, and basal half of antennomere 11 dark brown, apical half of antennomere 11 light brown. Body 3.2–4.4 mm long, ca. 1.7× as long as wide ( Fig. 27A ). Head densely punctate, usually bearing some large punctures ( Fig. 27A ); antennomeres 1–3 each longer than wide; remaining antennomeres each wider than long; antennomere 11 robust ( Fig. 27C ). Pronotum simply and very feebly curved at posterior margin, punctation similar to that on head. Elytra not transversely strigose; each elytron bearing nine punctate rows with small number of large punctures and moderate number of very fine punctures between rows ( Fig. 27D ); row 9 invisible in dorsal view, subhumeral row as long as ca. 1/3 of elytral length ( Fig. 27B ); elytral rows composed of larger punctures than those of pronotum ( Fig. 27A ); sutural stria fine, arising from apex ca. to apical 2/5 of the elytral length. Metathoracic wings fully developed. Mesoventrite with one shallow excavation between median carina and transverse carina ( Fig. 27E ); median carina of mesoventrite low ( Fig. 27E ); metaventrite without sexual dimorphism. Legs showing sexual dimorphism on protarsi, protibiae, mesotarsi, and metatibiae; metafemur robust, with small dorsal posteroapical projection ( Figs. 28G, 28H ). Fig. 29. Leiodes koreana Park & Ahn, 2007 .A – aedeagus, dorsal view; B – ditto, lateral view; C – male abdominal sternite 8; D – female abdominal sternite 8; E – coxite and stylus. Scale I: 0.5 mm for A and B; II: 0.2 mm for C and D; III: 0.1 mm for E. Male . Protibiae gradually and distinctly widening from base towards apex at internal margins ( Fig. 28E ); tarsomeres 2–4 of protarsi and mesotarsi expanded ( Fig. 28A ); metatibiae curved inwards ( Fig. 28C ); abdominal sternite 8 weakly curved ( Fig. 29C ); aedeagus as shown in Figs. 29A, 29B . Female . Protibiae gradually and very feebly widening from base towards apex at internal margins ( Fig. 28F ); protarsi and mesotarsi slender ( Fig. 28B ); metatibiae almost straight ( Fig. 28D ); abdominal sternite 8 forked in middle of anterior margin ( Fig. 29D ); coxites and stylus as shown in Fig. 29E . Differential diagnosis. Leiodes koreana is similar to L. masatsugui sp. nov. by the characteristic shape of the female abdominal sternite 8 (see Figs. 29D and 35E ), but may be distinguished from the latter by having males with a relatively slender aedeagus ( Fig. 29A ). In contrast, males of L. masatsugui sp. nov. have a robust aedeagus ( Fig. 32A ). Distribution. Japan (Kyushu, Shikoku, and Honshu), Korea . New to Japan .
