DiagnosisDiagnosis: A combination of the following characters distinguishes the new species from all other Southeast Asian congeners: adult males reaching 66.8 mm SVL and females 64.8 mm SVL; 9–11 supralabials; 8 or 9 infralabials; strongly tuberculated body and limbs, lateral fold with tubercles, tubercles on anterior portion of tail; tubercles extend from occiput to waist, and becoming larger tubercles posteriorly; 24– 29 dorsal tubercle rows; 40–48 rows of smooth ventrals; distinctly enlarged femoral scales in two rows, extending to precloacal region; 40–43 continuous femoro-precloacal pores in males; six rows of enlarged post precloacal scales; 17– 19 subdigital lamellae on the fourth toe; no enlarged median subcaudals; no reticulated pattern on head; paired dark blotches forming a V-shaped on occiput; dorsum blotched.

Coloration in life. Dorsum yellowish brown with dark blotches; eight pairs of dark square blotches on the trunk; paired dark blotches form a V-shaped marking on occiput; a dark line extends from posterior margin of nares to the anterior supracliliaris, interrupted by eyes, then continues to the ear opening and is interrupted by yellowish blotches above the ear; labials greyish bearing yellow and brown blotches; paravertebral blotches extend from nape to base of the tail; dark body blotches extend to tail where light countershading transforms into cream-colored bands which do not encircle the tail, 16 dark bands on the tail; tubercles on lateral fold and two or three series of tubercles adjacent lateral folds are yellowish. Venter white stippled with gray; subcaudals darkened with fine mottling; iris golden in color.

Comment 
EtymologyThe specific epithet is a noun in the genitive singular case, honoring a leading conservationist, ecologist, and primatologist Prof. Jatna Supriatna (University of Indonesia) for his enormous contributions to biodiversity conservation in Indonesia, as well as his generous friendship and support of the first author. Prof. Supriatna was born on Bali where the new species was discovered. His valuable contributions to science, policy making, and conservation management, as well as to popularizing the conservation ethic among his students and the general public are highly commendable. He is a legend in the field of conservation and locally he is known as “The Noah of Modern History”. The NGO, Conservation International, has called him “the Conservation Warrior of Indonesia”.
