Neoperla (Formosita) montivaga Zwick, 1977

Material studied: 1 ♀ Assam, Chingsao 13 vi 60 (F. Schmid; slide Z20.33; Mus.Lausanne) .

The original description records more than 60 straight lines of single punctures on the egg but it is unclear if they are arranged in triplets. The historical preparations are presently not available. The present new female contains no eggs. It is the first record since the original description from Bhutan and extends the range slightly. The caudal process of the vagina (Fig. 56) is shorter than in the other species.
