|Diagnosis||Diagnosis. 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 (Riyanto et al. 2015).|
Diagnosis (klakahensis): Cyrtodactylus klakahensis can be distinguished from all other congeners occuring in the Greater Sunda Islands (including Sulawesi) and Lesser Sunda Islands by the following combination of characters: (1) a deep precloacal groove in males, (2) three rows of enlarged precloacofemoral scales, of which the third row bears 37–38 pores in males, (3) three or four rows of posterior precloacal scales, (4) raised and strongly keeled dorsal tubercles in 15–19 rows at midbody, (5) an indistinct lateral fold, (6) 17–20 subdigital lamellae under the 4th toe, and (7) subcaudal scales which are not transversely enlarged (Hartmann et al. 2016).
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) (Riyanto et al. 2015)
|Comment||Synonymy: riyanto et al. 2020 synonymized Cyrtodactylus klakahensis with C. petani.|
|Etymology||The 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.|
The specific epithet klakahensis is a Latinized, toponymic adjective referring to the type locality Klakah (Lumajang Regency, Jawa Timur Province, Java, Indonesia) of the new species.
