Diagnosis

This species can be distinguished from all its congeners, except H. carinicaudus , H. nentur and H. tapajonicus by the combination of a uniform or longitudinally striped dorsum, a cream or red venter with 1-3 dark stripes or darkly checkered and 17-20 dorsal scale rows at mid-body (versus 20-23 in H. trivittatus ). From H. nentur , it differs in having a semi-divided nasal scale, whereas H. nentur has an entire nasal scale. From H. carinicaudus , it differs in having a cream or red venter with 1-3 dark stripes or darkly checkered or black with light spots (versus two series of dark semi-lunar marks in H. carinicaudus ). In some specimens, intermediate patterns are observed. From H. tapajonicus , it differs in having strongly keeled dorsal scales, whereas H. tapajonicus has only a weak dorsal keeling. Additionally, H. tapajonicus possesses a ventrolateral greenish stripe, which is absent in H. infrataeniatus (for information on references, see Suppl. material 3). Furthermore, H. tapajonicus and H. infrataeniatus have allopatric distribution ranges.

Distribution

Helicops infrataeniatus is recorded from the southern Brazilian States Mato Grosso do Sul, Sao Paulo, Parana, Santa Catarina and Rio Grande do Sul and from Paraguay, Uruguay and north-western Argentina Carreira Vidal et al. (2005) (Fig. 2 b).

Morphology remark

Kawashita-Ribeiro et al. (2013) reported subcaudal keels in H. infrataeniatus . In contrast, 57 of the 58 examined specimens during this study showed smooth subcaudal scales. Only SMNS 3065 had subcaudal keels (see Tables 1 View Table 1 , 2 View Table 2 ).
