Two subspecies are recognized, distinguished externally by wing-pattern and 

 structurally by minor modifications of the genitalia of both sexes. 



Zamarada regularis regularis subsp. n. 



(Text-figs 103, 104; PI- 24, figs 545- 54°; PI. 102 fig. 909; Map 2) 

 Zamarada flavicosta Warren ab. regularis Warren, 1909 : 115. 



<J$ (PI. 102, fig. 909). Distal margin of hyaline area on each wing very shallowly lunulate, 

 non-hyaline terminal area not excavate between veins M 3 and Cu lb ; dentate subterminal 

 fascia unbroken. 



In the male genitalia the apex of the right valve is three times as broad as that of the left 

 valve. 



In the female genitalia the ratio of the width of the crenulate, strongly sclerotized basal 

 plate to the width of the lamella antevaginalis is 3 : 2. 



Measurements. Fore wing: g 14.0-15-5 mm; 9- i3"5-i5'omm.

Zamarada regularis arcuata subsp. n. 



(Text-fig. 105; PI. 24, figs 547, 548; PI. 102, fig. 910; Map 2) 



[Zamarada flavicosta Warren sensu Warren, 1897 : 122 (part, nee lectotype). Misidentincation.] 



^ ^ (-P1- I02 > fi§- 9 10 )- Distinguished externally from the nominate subspecies by the 

 excavation of the non-hyaline terminal area of each wing between veins M 3 and Cu lb , 

 shallow on the fore wing, deeper on the hind wing. Distinguished structurally in the male 

 genitalia by the less broad apex of the right-hand valve, which is twice or slightly less than 

 twice as broad as that of the left valve, and in the female genitalia by the less broad, 

 crenulate, strongly sclerotized basal plate on the sterigma; ratio of width of plate to that of 

 lamella antevaginalis, 3 : 4.
