Remarks. An adequate description of this species was given by Ghauri (1971). However, some variation occurs as follows. Crown with submarginal black transverse band markedly and fully developed to undeveloped (Plate I: A–G). Pygofer side usually with distodorsal corner round, distoventral corner pointed, spine 1 long, other spines 3–5 in number, longish ( Fig. 2 B), but much variation occurs ( Fig. 1 ; Figs. 2 A–G); style usually as ( Fig. 3 L), apophysis of style is always shorter, but its shape varies ( Figs. 3 F–L); aedeagal shaft usually as in Figs. 4 C, 4E, but more variation is found ( Figs. 4 A–C, 4E–I), the aedeagal shaft is always somewhat constricted medially with roundly tapered margins in the distal half in posterior view ( Figs. 4 A–C) and the paired median lateral processes elongate ( Figs. 4 A–C, 4E–I), but the relative length of the shaft and the shape of median lateral process varies, and the number of aedeagal spines also varies usually from 3–5 ( Figs. 4 A–C, 4E–I). Males are easily identified from genitalia and in most cases even by colour (Plate I: A). Females could be confused with N. nigropictus and N. parvus , but differ in the shape of sternite VII (Plate VI: A–D).
