Diagnosis. This species is similar to L. mutilum (Vachal) from Japan. It is separated from L. mutilum by the female T1 medially with dense punctures as in Fig. 4 E (IS = <0.5–1d), hair tufts on male S6 boomerang-shaped ( Fig. 8D ) and gonostylus of the male genitalia elongate, elliptical ( Pesenko 2006, Fig. 65). In contrast, in L. mutilum , the female T1 has sparser punctures basally to medially (IS = 3 d in maximum), male S6 has three hair tufts (a basal, rounded median tuft and two apical, longitudinally narrow tufts) (Murao 2014, Fig. 7 of p. 235), and gonostylus broad apically ( Pesenko 2006, Fig. 59).
