Rana cf. chalconota

Seven adult males, SVL 43.6-49.0 mm (Table 5); seven adult females, SVL 46.3-65.6 mm (Table 5); three immature females, SVL 34.8-41.1 mm. All except two with strong reddish tinge to webbing (in preservative). All but four with dark dorsal spots. Ventral surface of legs with heavy dusting of melanophores; throat whitish, immaculate or with faint mottling. Vomerine teeth present. Toe four with full webbing to distal edge of distal subarticular tubercle, toes three and five with full webbing to base of discs. Males with velvety, whitish nuptial pad on first finger, not constricted; vocal sac openings on floor of mouth; spinules on granules of dorsum; no humeral glands. Males have larger tympanum (Table 5). Females approximate the size of those from Java (see above) .

These frogs are very similar to those we have identified above as R. chalconota . However, they differ greatly in size, in smaller relative tympanum diameter in males, in relative head length (Table 5), in absence of humeral glands in the males, and in the reddish webbing.

All 17 frogs were caught between 255 and 405 m ASL along clear, rocky streams in the disturbed forests controlled by Andalas University, Padang. Five of the Rana chalconota were collected at the same times and places as seven of the R. cf. chalconota .
