Leiodes babai species group

Species included. Leiodes babai Nakane, 1989 , L.kandai sp. nov., L. odaesanensis Park & Ahn, 2007 , L. yoshidai sp. nov.

Diagnosis. Elytra unicolor and with sparsely arranged punctures between punctural rows ( Figs. 7D , 10D , 13D ); punctures of rows relatively minute ( Figs. 7A , 10A , 13A ); mesoventrite with one distinct or shallow excavation between median carina and transverse carina ( Figs.7E , 10E , 13E ); protarsi showing sexual dimorphism, tarsomeres 2–4 of male protarsi a little expanded ( Figs. 8A , 11A , 14A ); mesotibiae without sexual dimorphism, simply square at interoapical corner; dorsal posteroapical projection of metafemur small and not sexually dimorphic ( Figs. 8G, 8H , 11G, 11H , 14G, 14H ); pubescence of metaventrite not showing distinct sexual dimorphism; aedeagus robust and bearing some small sclerites in inner sacs ( Figs. 9A , 12A , 15A ); male abdominal sternite 8 feebly curved ( Figs. 9C , 12C , 15C ); female abdominal sternite 8 with a spiculum ventrale at midwidth of anterior margin ( Figs. 9D , 12D , 15D ).

Differential diagnosis. Leiodes babai species group can be separated from other species groups by having minute serial punctures on elytra, and aedeagus robust and bearing some small sclerites in inner sacs.
