“…3B). The absence of dermal folds or tubercles on the ventrolateral margin of the tarsus distinguishes S. platycephalus from S. botocudo, S. bromelicola, S. cammaeus, S. caramaschii, S. palustris, and S. surdus (row of tubercles or crenulated dermal fold on the ventrolateral surface of tarsus; Caramaschi et al, 2009;Roberto et al, 2017) and S. dorisae, S. lacteus, S. planicola, and S. prasinus (well developed and smooth dermal fold on tarsus). The lack of dermal appendages on the elbow and heel also separates S. platycephalus from S. botocudo, S. bromelicola, S. cammaeus, S. caramaschii, S. palustris, and S. surdus (tubercles or crenulated dermal fold on heel; Caramaschi et al, 2009;Roberto et al, 2017), S. dorisae (dermal fold on elbow and triangular calcar appendage present), and Additionally, the presence of many enlarged tubercles in the subcloacal region, not forming a dermal fold, differentiates Sphaenorhynchus platycephalus from S. botocudo, S. bromelicola, S. cammaeus, S. canga, S. caramaschii, S. palustris, and S. surdus (dermal fold on the subcloacal region; Bokermann, 1966;Caramaschi et al, 2009;Araujo-Vieira et al, 2015: fig Sphaenorhynchus platycephalus also differs from S. dorisae, S. mirim, and S. planicola by the presence of maxillary and premaxillary teeth (absent in these species); and from S. carneus by the presence of vomerine, maxillary, and premaxillary teeth (absent in S. carneus).…”
