Diagnosis. Polyplectropus bamboosa appears to be most similar to P. chapmani Kumanski from New Guinea but differs in that the inferior appendages in ventral view appear more truncate posteriorly with an acute angle distomesally ( Fig. 16 ). Female. Unknown.

Distribution. Polyplectropus bamboosa was originally described from the holotype male collected from Litchfield N.P, in the NT ( Cartwright & Dostine 2022). The species is also widely distributed on Cape York Peninsula, N Queensland (latitudinal range 11.3– 15.5°S)

Remarks. The wing length of some North Queensland specimens is slightly more (4.9 mm) than the NT type specimen (4.2 mm).
