The tribe Leiochrinini of Diaperinae (Tenebrionidae) is presented for the first time from Korea. One unrecorded species, Ades masidai Nakane, 1963 are reported. Morphological photographs of adult, redescription and illustrations of diagnostic characteristics are provided.

 Tribe Leiochrinini of Diaperinae in family Tenebrionidae is mostly distributed in the Asian Palaearctic and Oriental Region. This tribe consists of 91 species of 9 genera in the Palaeartic region (Löbl et al., 2008). Members of Leiochrinini are recognized as follows: body nearly hemispherical, strongly convex, strongly glabrous, head conceal under pronotum, antennae rather robust and gradually from antennomeres 5 to 11, penultimate tarsomeres dilated, lobed beneath, distinctly broader than apical tarsomere (Lewis, 1894).

 Among them, genus Ades Guérin-Méneville is mostly distributed in the the Asian Palaeartic and Oriental Region. This genus consists of 19 species in the Palaeartic region (Löbl et al, 2008).

 In this paper, the genus Ades belonging to Leiochrinini is reported, as representative species by Ades masidai (Nakane, 1963) for the first time from Korea. Redescription, photos of adult, and illustrations of diagnostic characteristic are provided.

 Materials for this study were collected in damp decaying plants and are deposited in JUNG's Insect Collection (Seoul, Korea).

Redescription. Body length 3.0 mm; body hemispherical, strongly convex and glossy; mostly reddish brown in color, except blackish brown from antennomere 5 to 11 and ventral part (often). Head entirely concealed under pronotum; weakly convex, without punctures; frons smooth and weakly convex; eyes slightly emarginate; antenna relatively short and robust, not reaching to pronotum; submoniliform, widened from fifth antennomere to apical one; first antennomere ovate, second antennomere short, third antennomere elongate, about twice longer than second antennomere; fourth antennomere very small; fifth and sixth antennomeres serrated inner part, seventh to 11th antennomere gradually widened inner and outer sides; apical antennomere nearly circular; clypeus with sparse and stiff setae; apical maxillary palpomere thickly cylindrical; apical labial palpomere thinly cylindrical, tapered apically. Pronotum fan-shaped, glabrous, strongly shining, invisible punctures (x40 magnification); all margins rimmed; anterior margin strongly arched; lateral sides strongly narrowed apically; basal margin strongly arched; scutellum triangular. Elytra strongly convex, glabrous, and invisible hairs (x40 magnification); strongly narrowed apically, forming an almost complete circular outline; strial punctures very sparse, small and shallow, forming rows of punctures. Fore tibiae of leg gradually enlarged with strong setae outside; all tarsomeres lobed ventrally with strong and stiff setae.

Type Locality: Miho (sea beach), Naka-gun, Shimane, Honshu (holotype: 3 exs 1954, K. Masida leg.) 

Specimens examined: 5 exs. Yeosu-si, Jeollanamdo, Korea, 20 III 2011, S.-S. Lee under the dried pumpkin stems. 

Biological notes. This species occurs under damp decaying leaves in early spring (Nakane, 1963).
