Male adult of Polypedilum (Pol.) guianensis sp. n. is described based on material composed of adults captured over the canopy of the primary rainforest of Petit-Saut in French Guiana. On the basis of the specific distinguishing characters (inner verticals in 2 rows, caudal margin of frontal area low, widely bilobed; antenna 1250 µm long, terminal segment 730 µm long, tapering distally, AR 1.74; palpomere 3 longer than 4 and 5; tergites I-III and VIII with distinct circular pigmentation on postero-lateral corner; tergite IX with 3 characteristic ridges; superior volsella ending with one atypical short curved seta, outer seta located on distal half; gonocoxite with very long setae), P. guianensis sp. n. belongs to a separate group of the subgenus Polypedilum: the guianensis-gr. Therefore, the new species can be considered as a local biogeographic representative element of the primary rainforest of French Guiana. Remarks with short comments on the ecology of the new species are given.
