Hypothesized placement.

Nannaria “Bina” specimens are hypothesized to be closely related to N. monsdomia sp. nov. based on the following combination of gonopodal characters: Acropodite straight with extremely short distal region (Fig. 116A , red arrow). Prefemoral process curving laterally at base, crossing acropodite dorsally (Fig. 116A , red triangle). Nannaria “Bina” specimens differ from N. monsdomia sp. nov. based on the following combination of gonopodal characters: Prefemoral spine reduced to toothlike protrusion, not large, lobed as in N. monsdomia sp. nov. Prefemoral process thin, not enlarged near tip as in N. monsdomia sp. nov.
