We describe a new species of tree frog of the Scinax ruber clade from rocky field mountains in the states of Goiás and Minas Gerais in central and southeastern Brazil. Scinax rogerioi sp. nov. is characterized by medium size (SVL males 25.0–35.6 mm; females 28.0–34.5 mm); snout protruding in lateral view and almost subovoid in dorsal view; loreal region concave; adhesive discs on fingers medium-sized, wider than long; interrupted, irregular dark brown blotches on dorsum from behind eyes to inguinal region from head to inguinal region; inverted brown triangular interocular blotch; brown spot in loreal region; advertisement call is a multipulsed note, with 6 to 12 pulses (interval between pulses 0.02 to 0.03s), and a dominant frequency of 1.38 to 3.19 kHz. Description of the advertisement call and data on natural history are provided.

The genusScinaxis one of the most specious genera of treefrogs of the family Hylidae. Despite the high number of potential new species ofScinaxrevealed 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 genusScinaxdistributed along heterogeneous landscapes in southern Amazonia; and secondly assess the influence of environmental heterogeneity on the new species’ abundance and distribution.Scinax ruberoculatussp. 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 mothCopiopteryx 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.

We describe a new species of Ischnocnema from the Serra da Bocaina mountain range, state of São Paulo, southeastern Brazil, based on morphological, bioacoustic, and mtDNA data. The new species is retrieved with high support values within the I. lactea species series as the sister species of I. spanios. Ischnocnema bocaina sp. nov. is characterized by its medium size (18.6–19.0 mm), a smooth venter, a rounded snout in dorsal view and acuminate in lateral view, a slightly expanded subgular, single vocal sac, a round and whitish, poorly-developed glandular-appearing nuptial pad on the dorsal surface of the thumb, and a nonpulsed advertisement call with 9 to 18 notes. We raise to 38 the number of Ischnocnema species, the 12th described in the past 10 years.

Scinax curicica, a new species of treefrog of the Scinax ruber group is described from southeastern Brazil. The new species was previously considered as a slightly different population of Scinax duartei from State of Minas Gerais and is characterized by subacuminate snout in dorsal view, rounded in lateral view; canthus rostralis straight to nearly curved; brown to gray dorsal background with a interocular blotch extending in two longitudinal stripes to inguinal region with or without interruptions; yellow flash color blotches on hidden surfaces of thigh; height of caudal fins of tadpoles; advertisement call with multipulsed note, large number of pulses, and long call duration. Descriptions of the advertisement call, tadpole and data on natural history are provided.

Leptodactylus cupreus sp. nov. is characterized by the large size for the group (SVL 50.1–55.1 mm in males) and color pattern. The new species has a non-pulsed advertisement call, with call rate about 12 calls/s and a dominant frequency between 2,800 and 3,058 Hz.

We describe a new species of hylid frog, Scinax peixotoi, from Queimada Grande Island, southeastern Brazil. The new species belongs to the Scinax perpusillus species group, in which all known forms inhabit bromeliads, and is diagnosed by the following set of characters: moderate-size (males 18.8–20.7 mm SVL, females 22.4–25.1 mm SVL); canthus rostralis distinct; dorsal skin slightly rugose; and a distinct advertisement call with relatively low dominant frequency. The new species is known from a single population on Queimada Grande, an island of 43 ha, approximately 33 km distant from the coast of São Paulo State, where it inhabits scattered patches of bromeliads. The highly specialized and patchy habitat of S. peixotoi, associated with its small range size, make this species highly susceptible to stochastic or anthropogenic habitat disturbances, which could lead it to extinction.

Here we describe a new species of the toad genus Amazophrynella (Bufonidae) from the south margin of the Amazon River in Santarém, state of Pará, Brazilian Amazonia. The new species can be diagnosed by (1) medium body size for the genus: adult females 19.5–20.4 mm SVL, adult males 13.0–14.5 mm SVL; (2) snout acuminate in lateral view; (3) Finger I larger and robust; (4) Finger I nearly equal in size than Finger II; (5) palmar tubercle rounded, covering ¼ of hand; (6) pigmented callus in Finger I in males; in life: (7) brown stain on throat and chest; (8) black dots on venter. Males emit two distinct advertisement calls: the call type 1 consists of a relatively long note (mean 0.248 s) with a mean dominant frequency of 3526 Hz. The call type 2 is arranged in bouts of 6 to 22 notes with mean dominant frequency of 3450 Hz and much shorter note durations (mean 0.034 s). In this study we also redescribe the advertisement call of A. minuta, which also emits a second call type.

A new species of Pseudopaludicola is described from the Cerrado of southeastern Brazil. Pseudopaludicola facureae sp. nov. is diagnosed from the P. pusilla species group by the absence of either T-shaped terminal phalanges or toe tips expanded, and distinguished from almost all recognized taxa currently assigned to Pseudopaludicola (except P. canga, P. giarettai, and P. hyleaustralis) by possessing a non-pulsed advertisement call. However, the advertisement call of the new species consists of the emission of well-defined call series, whereas the advertisement call of P. giarettai is long (117–187 ms) and with an isolated emission pattern; respecting to P. canga, the new species emits very long notes series (up to 53 notes/advertisement call), compared to the short call series of P. canga (up to 9 notes/advertisement call); considering P. hyleaustralis, the new species has a shorter note duration (15–35 ms), higher note rate per minute (480–1860), and higher dominant frequency (4076–5108).
