Diagnosis. The diagnostic characters of external morphology and the male genitalia of the species are given under the previous species. The female genitalia of the species are close to those of L. amasa , but the lamella postvaginalis is weakly sclerotized, and weakly protruding outwards laterally; the lamella antevaginalis is not developed, but it is almost square and concave posteriorly in L. amasa ; the length of the ductus bursae is similar to that of the corpus bursae, while in L. amasa , it is shorter than the length of the corpus bursae; the corpus bursae is membranous, but weakly sclerotized in L. amasa .
