(2020) in the reclassification of Leptus, identified 220 species and divided the genus into 8 morpho-groups, and 40 subgroups of species and made 11 synonymies. In the couplet of 18 of key to subgroups of phalangii species group, an explanation is added in the parentheses. The key is changed as follows: Key to subgroups of phalangii species group 1.

(2020). Leptus (L.) clelandi Southcott, 1999 and L. (L.) tindalei Southcott, 1999 which were placed in the gifuensis species subgroup are placed in the meloidarum species subgroup. Thus, species in these two subgroups and the keys to species are changed as follows. meloidarum species subgroup BFe III without solenidion, TFe I without solenidion, Ge I with 1 solenidion, Ti I with 2 solenidia, Ti III with 1 solenidion, Ge II without solenidion, Ti II with 2 solenidia, TFe III with 1 seta, sensillary setae setulose in about distal half, ASens bases between AL and PL bases, solenidia on Ti II present, microseta on Ge I-II & Ti I normal, chelicerae punctate, 100 < fD < 125.
