Recent material composed of adults, collected in the primary rainforest in French Guiana, revealed the presence of five species of the genus Stenochironomus. In this paper, S. hallei sp. n. is described as male adult based on material captured over the canopy and the undergrowth aquatic habitats of the primary rainforest of Petit-Saut. On the basis of some atypical distinctive characters (posterior margin of frontal area widely bilobed; wing with 2 median dark spots; femur and tibia of PI-PIII with typical dark pigmentation; tergites II-VI with transverse caudal dark spots, tergite VII with 2 circular postero-lateral spots; postero-ventral part of tergite IX with 8 characteristic groups of tripled curved stout setae (4 on each side); anal point slender, spatulate apically; superior volsella with 4 inner setae and 1 typical outer seta; gonocoxite with long setae, apical ones overreaching tip of gonostylus), S. hallei sp. n. appears to belong to a separate group of species and probably can be considered as a biogeographic representative local element of the primary rainforest of French Guiana. Remarks on the taxonomic position of the new species are given.
