|Distribution||Malaysia (Sabah, Borneo ?)|
Type locality: Mendolong (670 m) (4° 54’ N, 115° 42’ E), Sipitang District, Sabah, Malaysia.
|Types||Holotype: FMNH 243839|
|Diagnosis||Diagnosis. A large species of Sphenomorphus (holotype SVL 82mm)having relatively shortlimbs, four supraoculars, prefrontals widely separated, loreals 1+1, 32 scale rows, 13 lamellae under the fourth toe, and no lateral dark band (Inger et al. 2001: 184).|
Comparisons. This species differs from other Bornean Sphenomorphus that have four supraoculars in several morphological features as shown in Table 2. In addition, the robust body, the light-spotted trunk, and the absence of a dark lateral stripe or band distinguishes this species from the others listed in Table 2. Three other Southeast Asian species of Sphenomorphus agree with S. crassa in having four supraoculars and separated prefrontals, S. cameronicus Smith, S. mindanensis Taylor, and S. victoria Brown and Alcala. All three of these species have dark lateral bands (Smith, 1924; Brown and Alcala, 1980), a pattern element absent in S. crassa . Sphenomorphus crassa is much larger than these species: S. cameronicus 6.5mm (Smith, 1924), S. mindanensis “large male” 55 mm(Brown and Alcala,1980), and S. victoria “mature female” 45 mm (Brown and Alcala, 1980). Sphenomorphus cameronicus has more scale rows (38) than S. crassa (Inger et al. 2001: 184).
Distribution: Not listed for Borneo by MALKMUS et al. (2002)
Abundance: only known from the type specimen (Meiri et al. 2017).
