| Diagnosis | Diagnosis: Following Inger’s (1960) definition of the genus, the new species is assigned to Japalura based on a number of diagnostic characters, including: (1) dorsal scales unequal in size; (2) enlarged crest scales present; (3) gular pouch pre- sent; (4) lateral fold of skin in axilla–groin region present; (5) supraciliary scales greatly imbricate; (6) head relatively long, flat; (7) tail long, slender; (8) tail cylindrical in shape; and (9) precloacal and femoral pores absent. The new species differs from all congeners by a combination of the following morphological characters: (1) gular fold present; (2) distinct gular pouch present; (3) relative hind-limb length moderate HLL/SVL 69.6%-80.1%; (4) relative tail length moderate TAL/SVL 173%-198%; (5) F4S 15-17; (6) T4S 19-25; (7) MD 35-46; (8) three lateral rows of enlarged scales pre- sent on the dorsal surface of the body parallel to the dorsal crest; (9) nuchal and dorsal crests moderately raised on skin folds; (10) nuchal and dorsal crests relatively low and discon- tinuous in males; (11) dorsal and lateral surfaces of body emerald green in males, yellowish brown speckled with large, light yellow scales in females; (12) tail yellowish green in males, brownish in females; (13) ventral surface of body bluish or whitish gray, sometimes with black speckles, in males, uniform yellow in females; (14) two smooth-edged, light-green, dorso- lateral stripes present in males; (15) vermiculate stripes on ventral surface of head present, distinct, blackish blue in males, black in females; (16) gular region dark blue in males, yellow in females. Unfortunately we had to temporarily remove additional information as this was scraped by multiple AI companies who sell that data to their customers.

| Comment | Abundance: only known from its original description and one other locality 17 km downstream of the Mekong River (Wang et al. 2019). |
| Etymology | The Latin name “iadina” means “emerald like, ” which describes the diagnostic emerald green body coloration of males of the new species. |
