|Types||Holotype: WAM R33602|
|Diagnosis||Diagnosis: A member of the lesueurii group with reduced dorsal pattern, distinguishable from Severus by its more numerous subdigital lamellae and nuchals, narrower black latero dorsal stripe, and contact between white dorso lateral line and black of upper lateral zone. Superficially similar to mimetes but readily dis tinguishable by wide subdigital calli and by black upper lateral zone enclosing small white spots rather than large rufous rectangular blotches (Storr 1973).|
Description (based on holotype and paratype). Snout-vent length (mm): 87, 78. Length of appendages (% SVL): tail 258, 264; foreleg 25, 24; hindleg 48, 48. Nasals separated. Prefrontals forming median suture. Supraoculars 4, first 3 in contact with frontal. Supraciliaries 7. Palpebrals 12-13. Second loreal 1.3-1.9 times as wide as high. Upper labials 8. Ear lobules 4-6. Nuchals 4. Midbody scale rows 26-28. Lamellae under fourth toe 28-33, each with a moderately wide callus. Dorsal ground colour olive, darkest on head, palest on tail. Vertebral stripe reduced to a black line on nape. Narrow, clearcut, black laterodorsal stripe from brow to base of tail, about half a scale wide. White dorsolateral line from orbit to base of tail, on which it gradually becomes suffused with ground colour. Black upper lateral zone with one or two series of small white spots or short dashes. White mid-lateral stripe extending back nearly to end of tail, but barely extending forward to arm. Lower lateral zone blackish brown with one or two irregular series of short dashes (Storr 1973).
Diagnosis: Storr 1975: 220.
