The male adult of S. uncinata Navás is similar to S. angustata Martynov, but can be distinguished by the intermediate appendages of segment X which are shorter than 1 / 4 of the length of lateral angles of segment IX. The lateral angles of segment IX are short, obtuse, and about 1 / 8 times as long as the length of preanal appendages.	en	Hoang, Duc Huy, Bae, Yeon Jae (2007): Vietnamese species of Stenopsyche McLachlan (Trichoptera: Stenopsychidae).

03E50178BA170D2F68EBFBFB06C29D61.taxon	discussion	Remarks. The species was originally described from Tonkin and recorded from Vinh Phuc Province in Vietnam by Mey (1995). The type and other materials are not available.	en	Hoang, Duc Huy, Bae, Yeon Jae (2007): Vietnamese species of Stenopsyche McLachlan (Trichoptera: Stenopsychidae).

03E50178BA170D2F68EBF9E600029AE2.taxon	discussion	Remarks. Although general shape of the female genitalia and forewing of S. vicina Navás (1932) is somewhat similar to that of S. angustata Martynov 1930, we are unable to identify this species based only on the original description. Only female adult of this species was described from Lao Cai Province. The deposition of the type material is unknown. We herein designate S. vicina Navás as nomen dubium.	en	Hoang, Duc Huy, Bae, Yeon Jae (2007): Vietnamese species of Stenopsyche McLachlan (Trichoptera: Stenopsychidae).

The larva of this species is similar to that of S. ulmeri Navás in having distinctive punctate pattern in head, but it an be distinguished by the shorter dorsal processes of forecoxae (Fig. 7 e), longer median part of posterior prosternite (Fig. 7 d), and smaller body size.	en	Hoang, Duc Huy, Bae, Yeon Jae (2007): Vietnamese species of Stenopsyche McLachlan (Trichoptera: Stenopsychidae).
