Abstract We here describe and illustrate a peculiar new species of Tricorythodes Ulmer (Leptohyphidae) based on a single nymph from a remote area of the Amazon biome in Colombia. The single nymph described here as T. spinosus sp. nov., presents a unique combination of characteristics: spiny tubercles on head, thorax and abdomen, elongated body and long and thin legs. Possible relations with other species in the genus are discussed.
