Syntypes. MCZ R-39040 and  UMMZ 78687View Materials; collected by M.A. Smith, March 1916 from “Khao Sebab, SE Siam ” Additional specimen  . FMNH 215981View Materials; collected by D.L. Damman, September of 1979 from Khao Soi Daow Wildlife Sanctuary 

Diagnosis. Adult males reaching 78.7 mm SVL; eight supralabials, 9 or 10 infralabials; 31–33 paravertebral tubercles; 19 or 20 longitudinal rows of dorsal tubercles; 42–44 rows of ventral scales; seven or eight expanded subdigital lamellae proximal to the digital inflection, 12–14 unmodified, distal, subdigital lamellae; 1 9–21 total subdigital lamellae on fourth toe; enlarged femoral and precloacal scales continuous; 23 or 24 enlarged femoral scales; proximal femoral scales one-half the size of distal femorals; 8–10 enlarged precloacal scales with pores on each in males; three rows of enlarged post-precloacal scales; two or three postcloacal tubercles; no pocketing between digits of hind or forefeet; dark pigmented blotches absent on top of head; posterior border of nuchal loop rounded; and four dark body bands ( Table 8). These characters are scored across all species of the Cyrtodactylus intermedius  complex in Table 7.

Remarks. No tissues were available from the type locality of Khao Sebab, Chanthaburi, Thailand however a specimen, FMNH 215981, and genetic material, LSUHC 9513, from Khao Soi Dao Wildlife Sanctuary in the adjacent mountain 30km north of the type locality were available. Upon morphological comparison of the two syntypes, UMMZ 78687 and MCZ R-39040, with FMNH 215981 from Khao Soi Dao the two populations show no morphological differences and are thus recognized here as conspecific. Thus, it is highly probable that if genetic analyses of the Khao Sebab population were conducted it would be closely related to or conspecific with the Khao Soi Dao population which falls within the Thai clade. The Thai clade is a member of the western group and the sister clade to a lineage containing [ C. thylacodactylus  sp. nov. [ C. intermedius  complex incertae sedis 1 and C. cardamomensis  sp. nov.]] from which it is separated by 5.4%–6.9% sequence divergence ( Table 4).
