The N. gulmargensis species-group

Diagnosis. The coloration and the pattern are similar to those of the N. sumatrana species-group. The speciesgroup is similar to the N. admiranda species-group, but its male genitalia differ in the significantly narrower valve, the short and rounded distal-ventral costal process directed ventrally, the short, robust and rounded ampulla, and the much shorter and narrower medial diverticulum of the vesica.
