Remark. Long time N. sumatrana effractoida  ssp. nov  . was erroneously considered by authors as N. effracta  . Unfortunately, the female holotype of N. effracta  is damaged and has no abdomen. Nevertheless, the correct treatment of the species is possible because of its external differences from N. sumatrana effractoida  ssp. nov  . and the second externally similar species, N. gulmargensis  , which is also distributed in Nepal and has the similar size and the forewing red pattern: in the female of N. effracta  the medial line is strongly loop-like curved in the cell, whereas in the females of both N. gulmargensis  and N. sumatrana effractoida  ssp. nov  . the medial line is more smoothly, arcuate curved in the cell. In addition, N. sumatrana effractoida  ssp. nov  . is not found in Nepal, while N. effracta  is the most widespread species of the genus in this country.

Diagnosis. Forewing length 11–11.5 mm in males and 12–13.5 mm in females. The species is most similar externally to N. gulmargensis  , N. klapperichi  and N. sumatrana effractoida  ssp. nov  ., but males can be distinguished from those of N. gulmargensis  and N. klapperichi  by the slightly broader posterior section of the medial line, and the smaller discal spots of the forewing; from those of N. sumatrana effractoida  ssp. nov  . they can be separated only by the genitalia structure; the females differ from those of N. gulmargensis  , N. sumatrana effractoida  ssp. nov  . and N. klapperichi  in the medial line strongly loop-like curved in the cell. In many cases a reliable identification is possible only by the genitalia structure. The male genitalia of N. effracta  are very similar to those of N. pseudoeffracta  , and differ only in the larger apical lobes of the juxta, the slightly broader valve, the slightly more developed medial costal angle, and the larger spikes on the aedeagus carina. The female genitalia of N. effracta  differ from those of N. pseudoeffracta  more significantly and can be separated by the slightly broader antevaginal plate, the more robust spines in the medial cluster of the corpus bursae, and the significantly larger signum.

Distribution. Nepal and North-East India (Assam, Meghalaya).
