|Types||Holotype: USNM 193961|
|Diagnosis||Diagnosis (genus Carinatogecko): All scales of the body, with exception of intermaxillaries, nasals, chin shields, and upper and lower labials, strongly keeled; three nasal scales contact nostril; digits weakly angularly bent, clawed, not dilated, not webbed, nor ornamented, with keeled transverse subdigital lamellae; dorsal pholidosis heterogeneous, small juxtaposed scales intermixed with tubercles; pupil vertical; tail segmented, caudal tubercles with bases in the middle of each segment, separated from posterior margin of segment by ring of scales (Fathinia et al. 2011); This diagnosis is based on Anderson 1999 and Szczerbak & Golubev (1986).|
Four key morphological characters discriminate between the species Carinatogecko heteropholis and Carinatogecko aspratilis (Golubev & Szczerbak 1981; Szczerbak & Golubev 1986; Anderson 1999). The first character is the size of the scales in the middle of the back, which should be smaller than the abdominals in C. aspratilis and more or less equal to the abdominals in C. heteropholis. Unfortunately, there seems to be a typographic error in Anderson (1999), where the stated relative size of the scales is reversed relative to the publications of Szczerbak and Golubev (Golubev & Szczerbak 1981; Szczerbak & Golubev 1986). Abdominals of the specimens we examined are more or less equal in size to the scales on the back. The second key character is the shape of caudal tubercles, which should be pointed with enlarged posterior facet in C. aspratilis, but flattened in C. heteropholis. The third key character is the presence (in C. aspratilis) or absence (in C. heteropholis) of identical tubercles on forelimbs as on dorsum. The last key character (the number of subdigital lamellae on the fourth toe), does not contribute to unambiguous species identification. C. aspratilis is reported to have 17–18 lamellae and C. heteropholis 15 lamellae, but specimens studied by ČERVENKA et al. (2010) have 16–17. In the original description of C. aspratilis, 17–19 lamellae are mentioned (Anderson 1973). Hence, ČERVENKA et al. (2010) conclude that “C. aspratilis could be a junior synonym of C. heteropholis, but due to the low number of known specimens and hence poorly understood morphological variability, the final resolution requires further study.”
|Comment||Type species: Bunopus aspratilis ANDERSON 1973 is the type species of the genus Carinatogecko GOLUBEV & SZCZERBAK 1981. ČERVENKA et al. (2010) and Bauer et al. 2013 showed that Carinatogecko nests within Mediodactylus (Type species: Gymnodactylus kotschyi STEINDACHNER 1870) and thus synonymized Carinatogecko with Mediodactylus. Torki 2020 argued that Carinatogecko is valid, based on morphological grounds.|
Distribution: See map in SMID et al. 2014 for distribution in Iran.
|Etymology||Named after Latin aspratilis with rough scales, from L. asper rough (Lewis, 1969).|
