Diagnosis. Polyplectropus berryensis appears to be most similar to P. bamboosa and P. chapmani Kumanski, 1979 from New Guinea, but it differs in that the inferior appendages in lateral view appear broadest in the posterior half.

Remarks. Generally, fork 1 is absent from the hind wings, however, at least one specimen of P. berryensis (illustrated specimen PT-1101) has hind wings with fork 1 present, like those of P. lochensis sp. nov. ( Fig. 2 ).

Distribution. Polyplectropus berryensis was recorded from about nine sites in the Top End of the NT and two sites from the Kimberley Region of northern WA ( Cartwright & Dostine 2022). Here it is reported from additional sites in the Kimberley and NT (latitudinal range 12.6– 16.4°S).
