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.
