“…Furthermore, tadpoles of S. ruberoculatus sp. nov. differ from tadpoles of S. boulengeri , S. garbei , S. nebulosus , S. pedromedinae , S. rostratus , S. sugillatus by the absence of labial arm and by presence of dark brown blotch on the distal portion of the tail (labial arm present, blotch on the distal portion of the tail absent; Duellman, 1978 ; McDiarmid & Altig, 1990 ; Hero & Mijares-Urrutia, 1995 ; Duellman, 2005 ; Gomes, Alves & Peixoto, 2014 ).…”

The genus Scinax is one of the most specious genera of treefrogs of the family Hylidae. Despite the high number of potential new species of Scinax revealed in recent studies, the rate of species descriptions for Amazonia has been low in the last decade. A potential cause of this low rate may be the existence of morphologically cryptic species. Describing new species may not only impact the taxonomy and systematics of a group of organisms but also benefit other fields of biology. Ecological studies conducted in megadiverse regions, such as Amazonia, often meet challenging questions concerning insufficient knowledge of organismal alpha taxonomy. Due to that, detecting species-habitat associations is dependent on our ability to properly identify species. In this study, we first provide a description of a new species (including its tadpoles) of the genus Scinax distributed along heterogeneous landscapes in southern Amazonia; and secondly assess the influence of environmental heterogeneity on the new species’ abundance and distribution. Scinax ruberoculatus sp. nov. differs from all nominal congeners by its small size (SVL 22.6–25.9 mm in males and 25.4–27.5 mm in females), by having a dark brown spot on the head and scapular region shaped mainly like the moth Copiopteryx semiramis (or a human molar in lateral view, or a triangle), bicolored reddish and grey iris, snout truncate in dorsal view, bilobate vocal sac in males, by its advertisement call consisting of a single pulsed note with duration of 0.134–0.331 s, 10–23 pulses per note, and dominant frequency 1,809–1,895 Hz. Both occurrence and abundance of the new species are significantly influenced by silt content in the soil. This finding brings the first evidence that edaphic factors influence species-habitat association in Amazonian aquatic breeding frogs.

“…In addition, tadpoles of S. onca sp. n. differ from those of S. garbei , S. nebulosus , S. pedromedinae , and S. rostratus by the absence of labial arm (labial arm present; Duellman 1978, Hero and Mijares-Urrutia 1995, Duellman 2005, Gomes et al 2014). …”

A new tree frog species of the genus Scinax from the interfluve between the Purus and Madeira rivers, Brazilian Amazonia, is described and illustrated. The new species is diagnosed by medium body size, snout truncate in dorsal view, ulnar and tarsal tubercles absent, nuptial pads poorly developed, skin on dorsum shagreen, dorsum light brown with dark brown spots and markings, white groin with black spots, anterior and posterior surfaces of thighs black, and iris bright orange. The advertisement call consists of a single short note, with 16−18 pulses and dominant frequency at 1572−1594 Hz. Tadpoles are characterized by body ovoid in dorsal view and triangular in lateral view, tail higher than body, oral disc located anteroventrally and laterally emarginated, dorsum of body uniformly grey-brown with dark brown eye-snout stripe in preservative, fins translucent with small to large irregular diffuse dark brown spots.

“…Scinax constrictus is represented by specimens from Goianópolis and Palmeiras, Goiás (the latter is the type locality; Lima et al, 2005), and Barra do Garças, Mato Grosso, Central Brazil. The tadpole of S. nebulosus was described based on individuals from Cabo de Santo Agostinho, Pernambuco, Brazil (Gomes et al, 2014), and therefore could belong to Scinax sp. 5.…”

“…Further, the dorsolateral dermal constriction on the shoulders in adults and the two separate tubercles above the cloaca in females of S. constrictus also occur in males and females of S. nebulosus . Santos et al (2019) suggested that the absence of submarginal papillae could differentiate tadpoles of S. constrictus from those of S. nebulosus (Gomes et al, 2014; therefore, very likely corresponding to Scinax sp. 5, see above).…”
