CommentDiagnosis. Cyrtodactylus petani sp. nov. is distinguished from all Javan and Sundaic species by having a maximum SVL up to 57.2 mm; nine or 10 supralabials; seven or eight infralabials; strongly tuberculated body and limbs; 20–25 paravertebral tubercles; 30–35 ventral scales; enlarged femoral scales; enlarged precloacal scales; 17–18 subdigital lamellae on the fourth toe; 31–35 continuous precloacal and femoral pores in males, pores absent in females; precloacal groove absent, no enlarged median subcaudals; tubercles on anterior portion of tail; no reticulated pattern on head; paired dark blotches forming a V-shaped on occiput; blotched dorsal pattern; and no paired, dark, semi-lunar-shaped blotches on upper nape.

Comparisons. Cyrtodactylus petani sp.nov. differs from its sister species C. batucolus Grismer, Chan, Grismer, Wood & Belabut, 2008 by having fewer precloaco-femoral pores (31–35 versus 43–46) and a smaller maximum SVL (57.2 mm versus 75.2 mm). Cyrtodactylus petani sp. nov. differs from C. seribuatensis Grismer & Youmans, 2006 in having fewer precloaco-femoral pores (31–35 versus 40–43) and a smaller maximum SVL (57.2 mm versus 75 mm). The new species is distinguished from C. fumosus by lacking a precloacal groove, having fewer paravertebral tubercles (20–25 versus 30–33), fewer subdigital lamellae under the fourth toe (17–18 versus 22), fewer precloaco-femoral pores (31–35 versus 46–50) and a smaller maximum SVL (57.2 mm versus 75.2 mm). From C. marmoratus sensu stricto (lectotypes; see Rӧsler et al. 2007) it can differentiated by having tubercles in the ventrolateral body fold, fewer ventral scales (30–35 versus 38–47), fewer precloaco-femoral pores (31–35 versus 45–50) and fewer subdigital lamellae under the fourth toe (17–18 versus 20–24 lamellae). It can be differentiated from C. semiadii Riyanto, Bauer & Yudha, 2010 by having tuberculation on both forelimbs and hind limbs, presence of precloaco-femoral scales and fewer paravertebral tubercles (20–25 versus 37–40). 
EtymologyThe specific epithet petani refers to the fact that the type series was collected on a farm. Petani means a farmer in the Indonesian Language and is here treated as a noun in apposition.
