 Polyplectropus novafriburgensis is most similar to P. alatespinus, new species, in the overall shape of the preanal, intermediate, and inferior appendages. P. novafriburgensis can be distinguished from this species by the spines in the endothecal membrane forming a V-shape when the membrane is everted and not projected anterolaterad as in P. alatespinus, by the absence of peg-like setae on the dorsal surface of the ventral branch of the inferior appendage, and by the shorter and more linear ventral branch.   
 Adult. Length of forewing 5.3–5.7 mm, n = 4. Color of head, thorax, and legs dark-brown; setae on body dark-brown with golden reflections; tegulae with dark-brown setae; setae on wings dark-brown with golden reflections, entire specimen appearing black from a distance.   
 Male genitalia. Sternum IX in lateral view deltoid, anterior margin submedially produced, posterior margin sinuate and submedially concave; in ventral view rectangular, anterior margin concave, posterior margin with slight median flange. Tergum X membranous, oblong, bearing dorsal microsetae. Intermediate appendage not longer than inferior appendage, digitate, with a pair of long apical setae; in dorsal view digitate; in caudal view digitate, directed posterad. Preanal appendage tripartite; dorsolateral process elongate, originating from dorsum of mesolateral process, recurved posterad, tapering into acute apex; mesolateral process setose; in dorsal view orbicular, in lateral view deltoid; mesoventral process setose; in lateral view hook-like, dorsally produced into digitate lobe, with ventrad-directed sclerotized apex, ventral margin slightly concave, posterior margin truncate; in caudal view processes separated with dorsal digitate lobe, ventral margin of process undulate and with slight median sclerotized point. Inferior appendage bipartite with anterior basal plate not extending anterad beyond sternum IX when observed in lateral view, anteriorly bilobed; dorsal branch setose, in lateral view oblong; in ventral view broad, lateral margin subapically produced, undulate, posterior margin subacute, expanding posterad into ventral branch; ventral branch setose, elongate, bearing stout setae along entire dorsal surface, in lateral view digitate, rounded posterad; in ventral view digitate, posteromesal margin sinuate, gradually converging mesally. Phallus long; dorsal phallic sclerite in lateral view sinuate, apex pandurate; apex of dorsal phallic sclerite in dorsal view rounded; endothecal membrane with 2 basally fused, stout, medium-sized, sclerotized spines, apically acute and bent laterad, when endothecal membrane is everted in caudal view spines are V-shaped.
