|Types||Holotype: ZRC 2.6989, adult male, collected on 7 October 2012 by Evan S.H. Quah and Shahrul Anuar Mohd Sah. Paratypes. ZRC 2.6990, LSUHC 9969, 9970, 9972 and 9973 were collected on 5 November 2010 from the same locality as the holotype by Evan S.H. Quah, Shahrul Anuar Mohd Sah and Mohd Abdul Muin. LSUHC 10941–10944 were collected on 7 July 2012 by the same collectors at the same locality.|
|Diagnosis||Diagnosis: Cnemaspis grismeri sp. nov. differs from all other Southeast Asia species of Cnemaspis in having the unique combination of adult males reaching 48.8 mm SVL, adult females reaching 50.6 mm SVL; 8–9 supralabials; 7–9 infralabials; large, lateral postmentals separated at midline by one or two smaller postmentals; forearm, subtibials, ventrals, subcaudals, and dorsal tubercles keeled; 27–32 paravertebral tubercles; tubercles on flanks, relatively small and not linearly arranged; tubercles within lateral caudal furrow; ventrolateral caudal tubercles present anteriorly; median subcaudal row not enlarged; no keeled, median subcaudal row of enlarged scales; two or three postcloacal tubercles; continuous row of eight to ten precloacal pores; subtibial scales not shield-like; no enlarged submetatarsal scales; 25–31 subdigital lamellae on fourth toe; no distinct, large, dark spots on neck; dark shoulder patch enclosing two white to yellow ocelli; prominent, wide, yellow to white, postscapular band; yellowish bars on flanks; distinct, dark, caudal bands present posteriorly; subcaudal region pigmented, not immaculate. Scalation and body size differences are summarized across all Southeast Asian species in TABLE 1 (Wood et al. 2013).|
Comparisons. Cnemaspis grismeri sp. nov. differs from all other species of Cnemaspis in numerous aspects of scalation and color pattern as summarized in TABLE 1. It is most similar to its sister species C. mcguirei (L. Grismer et al. unpublished) but differs in being smaller (maximum SVL=50.6 mm in C. grismeri sp. nov. versus SVL=65.1 mm in C. mcguirei) and having a significantly lower mean number of subdigital lamellae on the fourth toe (28.8 versus 32.5; p<0.01). Additionally, the lower, anterior shoulder spot is less prominent and the lateral baring is generally more distinct (Figs. 2 & 3). Cnemapsis grismeri sp. nov. is the sister species of C. mcguirei who are separated by a 7.3–11.7% sequence divergence in the mitochondrial gene ND2.
|Comment||Abundance: only known from its original description (Meiri et al. 2017).|
|Etymology||This species is named in honor of Prof. Dr. L. Lee Grismer of La Sierra University, Riverside, California, USA for his tremendous contributions to the advancement of the field of herpetology in Malaysia. Coincidentally, Cnemaspis grismeri sp. nov. is the closest relative of C. mcguirei, a species that Dr. Grismer had named in honor of his close friend and colleague Prof. Dr. Jimmy A. McGuire of the University of California Berkeley, USA.|
