Paratypes. The collection data for the paratypes (all females) LSUHC 9230–33 and LSUHC 9235 are the same as the holotype. 
DiagnosisDiagnosis. Leiolepis ngovantrii differs from all sexual species of Leiolepis in lacking males; it differs from all asexual species in having a combination of nine rows of enlarged keeled scales across the forearm; 37–40 subdigital lamellae beneath the fourth toe; a relatively narrow head (0.71–0.83); 50–53 dorsal scales between the dorsolateral stripes; absence of a lateral, caudal stripe; having 24 or 25 gular scales between the enlarged, mandibular scales; the ventrolateral stripe not reaching the axillary region; absence of a black, Yshaped marking in the pectoral region, a vertebral stripe, and eyespots bearing white centers; presence of transverse bars on the flanks; presence of thin, transverse, dorsal, caudal bars, and the absence of dorsal, caudal blotches.
CommentSympatry: Leiolepis ngovantrii lives in sympatry and, in some places, syntopy with its maternal ancestor L. guttata. 
EtymologyThis species is named in honor of Mr. Ngo Van Tri whose extensive field work in southern Vietnam resulted in the discovery of this new, asexual population as well as many other new species of lizards.
