Diagnosis
The female closely resembles L. nigra in that the body and legs are almost black and FW is clouded with dark brown (photos of the holotype of L. nigra : http://n 2t.net/ark:/65665/ 34f86a418-891c-4ad3-930e-51495fc57b4a). However, they are easily distinguished by the colour of pubescence on the body. Except for the areas covered with dense whitish pubescence and setae, pubescence on the front, mesosoma and metasoma is reddish in L. koreana but whitish in L. nigra . The scape, pedicel, Fl1–2, and basal half of Fl3 dorsally have dense appressed whitish pubescence in L. koreana ( Fig. 3B View Fig ), but such pubescence is lacking or at most sparse in L. nigra . The wings are much darker in L. nigra than in L. koreana . The female and male have the hind tibia with a longitudinal groove along the upper margin of the inner brush. The male is unique in having a pair of short, oblique, linear tubercles on S4 subbasally ( Fig. 1K View Fig , red arrows).
Etymology
The specific epithet is derived from its type locality, Korea.
