Diagnosis. This species is similar to L. baleicum (Cockerell) and L. caliginosum Murao et al. from eastern Asia. Male of this species is separated from these species by a combination of the following character states: clypeus with yellow spot on lower half; mesoscutellum punctate (Murao & Tadauchi 2007, Fig. 53L); tibiae with yellow spot basally and apically; gonostylus of genitalia trunctate on top (Murao et al. 2006, Figs 6 C–D); and ventral retrorse lobe of genitalia slender (Murao et al. 2006, Fig. 6 H). In contrast, both L. baleicum and L. caliginosum have clypeus generally black over entire surface, mesoscutellum reticulate-rugulose in L. baleicum and reticulatepunctate in L. caliginosum (Murao & Tadauchi 2007, Figs 36L, 42L), tibiae nearly black over entire surface, gonostylus rounded in L. baleicum and ovate in L. caliginosum (Murao et al. 2006, Figs 6A–B, 6 E–F), and ventral retrorse lobe slender in L. baleicum and broad in L. caliginosum (Murao et al. 2006, Figs 6 G, 6I). The differences of female among L. baleicum, L. caliginosum, and L. vulsum are shown by Murao et al. (2006). As stated in L. baleicum, the differences of female among three species are subtle.
Specimens examined. (n = 1) [South Korea] JB: 1♂, Jeonglyeongchi, 16. vii. 1991 (K. Kanmiya, ELKU). Distribution. North Korea, South Korea (new record), Russian Far East, China, Japan. Flight period in South Korea. Male: July. According to Maeta (2014), the life history of female in Japan are described as follows: overwintered females began to nest solitarily in early March and continued their nesting activity until early June; overwintered generation appeared from late May to mid June; new females dispersed from their natal nest after insermination.
Flower records in South Korea. Not recorded.
