– Ti II with 2 solenidia ...................................................................................................................... 9

9. BFe III with 2 setae ............................................................................. guilinicus species subgroup

14. Chelicerae striated .................................................................................... treati species subgroup

– Chelicerae punctate ................................................................................................................... 15

15. fD> 125 .......................................................................................... millipedius species subgroup

– fD <125 ..................................................................................................................................... 16

16. 100 <fD <125 ............................................................................... meloidarum species subgroup

– fD <100 ..................................................................................................................................... 17

17. Scutum distinctly longer than wide (L−W> 15 μm) ......................... gagrellae species subgroup

– Scutum otherwise ...................................................................................................................... 18

18. Scutum distinctly wider than long (usually W−L ≥ 14 μm) .................. gifuensis species subgroup

– Scutum length and width semi-equal (L> W; or W−L <14 μm) * ............................................. 19

19. Ti I <125 ........................................................................................ molochinus species subgroup

– Ti I> 125 ................................................................................................................................... 20

20. Ti III> 340 & Ti I> 280 ........................................................... boggohoranus species subgroup

– Ti III <340 or Ti I <280 ................................................................... phalangii species subgroup

* The character “L<14 μm” in the parentheses should be replaced with “L> W; or W−L <14 μm” in the definition of the molochinus, boggohoranus and phalangii species subgroups in Saboori et al. (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.
