Description. This species was described from a single female subimago from Southeast China, “Chekiang, Chusan”, captured 11.VI.1931 by O. Piel. This location is nowadays known as Zhou Shan Island, in Zhejiang province. The type material could not be located, and this specimen is neither housed in the Museum national d’Histoire Naturelle de Paris ( Berthelemy 1965, J. Legrand, comm. pers.) nor in the Museum of Zoology of Barcelona ( Alba-Tercedor & Peters 1985). Based on the drawing of the hindwing, we think it plausible that this species belongs to the genus Dudgeodes ; the shape of the costal process and the length/ width ratio (ca. 1.8) is similar to that of D. hutanis . Dudgeodes lugens would differ from D. hutanis by having more numerous intercalary veins in the cubital field. The only other mention of Teloganodidae from continental China was made by Tong & Dudgeon (2000) who mentioned two nymphs of “ Teloganodes tristis ” from Tai Pau Forest, Hong Kong. The drawings clearly indicate that this species belongs to the genus Dudgeodes and is closely related to D. hutanis . The status of Chinese Dudgeodes , whether the nymphs from Hong Kong are the immature stage of D. lugens or are in fact conspecific with those of another species described here or even a new species may be solved when more material becomes available.
