Leiodes naraharai species group

Species included. Leiodes naraharai sp. nov., L. shuheii sp. nov.

Diagnosis. Elytra clearly bicolored, with black stripes along lateral margins ( Figs. 55C, 55D , 58C, 58D ) and with sparsely arranged large punctures between rows of punctures ( Figs. 55F , 58F ); mesoventrite without distinct excavations between median carina and transverse carina ( Figs. 55G , 58G ); tarsomeres 2–4 of protarsi sexually dimorphic, a little expanded in male ( Figs. 56A , 59A ); mesotibiae without sexual dimorphism, simply square at interoapical corner; male metafemur bearing a prominent dorsal projection posteroapically, the projection clearly smaller in female ( Figs. 56G, 56H , 59G, 59H ); pubescence of metaventrite not showing sexual dimorphism; aedeagus relatively robust, without distinct and large sclerites in inner sacs ( Figs. 57A , 60A ); male abdominal sternite 8 weakly curved ( Figs. 57C , 60C ); female abdominal sternite 8 with a spiculum ventrale at a central point of anterior margin ( Figs. 57D , 60D ).

Differential diagnosis. The Leiodes naraharai species group can be separated from other species groups by the elytra with black stripes along the lateral margins and the male metafemur bearing a prominent dorsal projection posteroapically.
