Remarks. An adequate description of this species was given by Ghauri (1971). But some variation occurs as follows. Crown and forewing with or without black markings (Plate II: A–F). Pygofer side usually distodorsal corner round, distoventral corner pointed, spine 1 long, spine 2 and others absent (Fig. 8 B), but much variation is found (Figs. 6–9); style usually as in Fig. 10 C, apophysis of style is always shorter, but its shape varies (Figs. 10– 11); aedeagal shaft usually as in Figs. 12 B, 13B, but much variation is found (Figs. 12 A–F, 13A–I), the paired median lateral processes of aedeagal shaft short (Figs. 12 A–F, 13A–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. 12 A– F, 13A–I). The nearly round crown of both males and females make this species very distinct (Plate II: A–F).
