Excluding members of the Paridris nephta  species group, Paridris bifurcata  is the only species of Paridris  in Southeast Asia with two basiconic sensilla on A8.

Galloway (1984) erected Neoparidris  to accomodate a species that had attributes of Paridris  but lacked the small eyes, compact ocellar triangle, and incomplete notaulus that characterized his concept of the group. In his discussion of Neoparidris  , Galloway commented that this species may ultimately belong in Paridris  when its limits became clearer, and this is indeed the case.
