Résumé

A new species of Sicyopterus, a freshwater goby, is described from streams of Papua New Guinea on the island of West New Britain, where specimens were caught during two field missions in 2015 and 2019. It differs from other species belonging to the genus by a combination of characters including the upper lip morphology, a second dorsal fin with one spine and 10 segmented rays, the scales in the lateral, predorsal, transverse back, transverse forward and zigzag series, and live colours with courting males having a coal black body with occasionally a pearl white necklace.
