Koi Carp, which originated in Japan, come in more than a dozen varieties and are distinguished by their colouring, patterning, andscalation. The Kohaku variety is a white-skinned koi, with large red markings on the top.

Finally, the population from "Cordillera de Los Altos" can be differentiated from the other species of this genus by subtle characters of coloration andscalation. Therefore, applying the general lineage species concept [57], we recognize the Phyllopezus population from the "Cordillera de Los Altos" as a separate species, described below.

Annable T (1985) Subcaudalscalation analysis of Pseudonaja textilis (Dumeril and Bibron) in the eastern Riverina region.

The frontalscalation patter in some groups of toothcarps (Pisces, Cyprinodontiformes).

The three species are distinguished from each other based on headscalation, length, and distribution (Cogger 2014).

Differences in pigmentation andscalation were the bases for these opinions.

Table 1 lists features ofscalation, including the number of ventral, subcaudal, labial and ocular scales, dorsal scale rows and definitions of measuring methods.

Furthermore, it is noteworthy to mention here that Coluber bholanathi and Coluber gracilis (Gunther, 1862), an allopatric congener, both share somescalation and coloration characters in common, except dorsal scale row count --19:19:12-15 (fide Gupta et al.

The head is pointed and dorsalscalation consists of a mixture of small flat scales and other enlarged keeled and tuberculated forming keels.
