This is a very difficult genus having small and little outer differences. The genus needs a revision; there are observations where the identifier is left with uncertain feelings even though all seems to fit. Here, suspicions of kerangatis and guttulata being present also in peninsular Malaysia are coming in. N. textilis (as ssp. textilis and ssp. parvipuncta) and obliterata may be strictly connected with Indian subregion. The Chinese taxa (seriaria, angustaria, margaritaria, montanaria, obliquaria) are one possibility but they have never been reported south from China.

@juhakinnunen Thank you for the info. According to Moths of Borneo, N. kerangatis and N. guttulata have larger spots than N. textalis ( and "Males and, to a lesser extent, females of kerangatis have deeper forewings than in guttulata, with the grey spots darker and generally less lanceolate." ( Out of these three species, it would seem mine is most likely to be N. kerangatis, given the dark spots that seem larger than those in N. textalis. Moths of Borneo does not mention any other species in the genus, and I have no other sources to check the distinguishing features.
