Other material — 1/0/0 (1/0/0 mounted), India, Uttaranchal , Garhwal Himalayas , Dhundeshwargad stream, a tributary of Alaknanda River, viii- 2006 leg. Kumar.

Remarks — The specimens from Oman fit the description of Limnesia pinguipalpis , described from the Oriental part of India (Maharashtra, Karnataka, Tamil Nadu - Cook, 1967). The only non-Oriental record from India comes from Garhwal Himalayas (see above). Limnesia pinguipalpis is similar to L. monodi but differs in the more extensive secondary sclerotization associated with the posterior end of the male genital field ( Fig.10B ), and the ventral margin of P-2 more or less straight ( Fig. 10C, 10E ) vs. convexly protruding in L. monodi (see Fig. 10D ).

Distribution — India; Oman (" Limnesia [Tetralimnesia] sp." Gerecke, 2004).

Subfamily Protolimnesiinae Viets, 1940
