looking at Google picture search, pulchellus has no dark spots within the white tail rings, peguensis, yes.
Diagnosis peguensis (from reptile-database):
Adult males reaching 114.1 mm SVL, adult females reaching 113.3 mm SVL; 9–11 supralabials, 8–10 infralabials; tubercles of dorsum moderately large, strongly keeled and widely separated with no intervening smaller tubercles; no tubercles on ventral surface of forelimbs, gular region, or in ventrolateral body fold or these regions may be weekly tuberculated; 33–43 paravertebral tubercles; 22–26 longitudinal rows of dorsal tubercles; 29–34 rows of ventral scales; 21–26 subdigital lamellae on fourth toe; 33–39 femoro-precloacal pores in males; dorsum not bearing scattered, white tubercles; four dark body bands with a body band/interspace ratio of 0.75–1.25; 8–10 dark caudal bands on original tail; white caudal bands in adults immaculate; and posterior portion of tail hatchlings and juveniles not white (Table 4). These characters are scored across all species of the Cyrtodactylus pulchellus complex in Table 6 [GRISMER et al. 2012].
