L. macrobipunctata was previously described by Choe (1986) in his Ph.D. thesis, but it was not published. Hossain et al. (2019) validated this taxon by providing a description and illustration adopting the same species name. Comparison of the original description and illustrations of L. macrobipunctata Hossain et al., 2019 (Choe, 1986 nom. nud. & Hossain et al., 2019) and the specimens of the Choe���s collection at CNU with the descriptions and illustrations of L. ishiharai Dworakowska, 1972 (Dworakowska, 1972) indicates that these two taxa are synonyms.
