A new species of Anomaloglossus is described from the Venezuelan Guayana; it is the 21 st described species of Anomaloglossus from the Guiana Shield, and the 15 th from Venezuela. This species inhabits rainforest on granitic substrate on the northwestern edge of the Guiana Shield (Estado Amazonas, Venezuela). The new species is distinguished from congeners by sexual dimorphism, its unique male color pattern (including two bright orange parotoid marks and two orange paracloacal spots on dark brown background), call characteristics and other morphological features. Though to the new species is known only from the northwestern edge of the Guiana Shield, its distribution may be more extensive, as there are no significant biogeographic barriers isolating the type locality from the granitic lowlands of Venezuela.

A new species of Cosmetidae belonging to the genus Metavononoides Roewer, 1928 is herein described. Metavononoides melanacanthus sp. nov. is clearly recognized by its distinctive tarsal formula, its long legs (reaching over 60 mm), and by its characteristic color pattern. The new species is the twelfth species included in the genus. It is known only from two localities: the type locality, Barra de São João, Casimiro de Abreu and from Aldeia Velha, Rio de Janeiro, Brazil.

A new species of the genus Pristella Eigenmann, 1908 (Pristella crinogi sp. nov.) is described from the middle rio Tocantins and middle rio São Francisco basins, Brazil. The new species can be diagnosed from its two congeners, Pristella ariporo Conde-Saldaña, Albornoz-Garzón, García-Melo, Villa-Navarro, Mirande, and Lima, 2019 and Pristella maxillaris (Ulrey, 1894), by a combination of color pattern and teeth morphology characters. A phylogenetic analysis of the genus recovered P. crinogi as the sister taxa of P. ariporo. Pristella crinogi, along with P. ariporo, are the first characiform fishes, and one of the first bony fishes, to be reported as presenting a reversed sexual dimorphism, with females presenting a more developed color pattern than males. Comments on the miniaturization of the species, as well as remarks on the biogeography of the genus Pristella, are presented.

Gymnodactylus amarali Barbour, 1925, was previously considered to be a subspecies of G. geckoides, with a wide distribution in the Brasilian cerrados. Examination of a specimen from Alto Parnaíba, Maranhão, near the type locality (Engenheiro Dodt, Piauí), indicates that it is a proper species, apparently limited to the upper Parnaíba basin. The form previously identified as G. geckoides amarali is described as a new species, G. carvalhoi, type locality Ipueiras, State of Tocantins, thus diagnosed: color pattern plain or, more often, with moderately contrasted ocelli; dorsal tubercles in 13 - 16 poorly organized longitudinal rows (mode 14, 72%); 31 - 49 tubercles in a paramedian row; 17 - 22 transverse rows of ventral scales; 13 - 18 infradigital lamellae on toe IV; tail longest in the genus. The new species is statistically compared to parapatric G. geckoides, widespread in the caatingas. Although only one meristic character (number of tubercle rows) is by itself diagnostic, the species are easily told apart. It is thought on provisional evidence that they are better considered for the time being as full species, not subspecies. A brief consideration is made of the speciation model that seems suitable, to wit, parapatric.

A new species of the genus Neapion Alonso-Zarazaga, 1990 subgenus Neotropion Alonso-Zarazaga, 1990 (Brentidae: Apioninae) is described and illustrated. Neapion (Neotropion) cleidecostae sp. nov. (Type locality: Paraguay, Misiones) is the second Apioninae species from South America with dense, thin vestiture and raised areas on the elytra. In addition to these characters, vestiture color pattern and male genitalic characters such as penis shape, length of the tuning fork-shaped sclerite in the internal sac (the largest found in Apioninae), and shape of the tegminal plate are diagnostic of this new species.

Liolaemus dorbignyi is re-described, and its type locality restricted to the Sierra de Fiambalá, Catamarca Province, Argentina. Also, Liolaemus scrocchii sp. nov., a new species of Liolaemus belonging to the L. montanus series, previously confused with L. dorbignyi , is described. This new species inhabits the phytogeographic region of Puna in Argentina at 3500 m. and is distributed in Jujuy and northwestern Salta provinces. Diagnostic characters include the color pattern, (composed of transverse paravertebral spots, that are band shaped and never reach the lateral region, and never contact the vertebral zone), and the number of scales around midbody. Several populations from different localities were considered L. dorbignyi because of their color pattern and squamation. Even though part of this confusion is clarified in this contribution, some populations still require further study.

A new monobasic genus of Nanophyidae, Indophyes, and a new species, I. yaromi, are described from southern India (type locality: Karnataka, Bilukoppa, 800 m, 40 km W Mudigere). The new genus is characterized by 5-segmented antennal funicle, strong sexual dimorphism of the rostrum, dentate femora, male tibiae unarmed, abdominal suture IV distinct in both sexes, male pygidium not foveate and 8th elytral interstria not crenulate.  The subulate form of rostrum—abruptly narrowed apically—is unusual among the Nanophyidae.

Abstract A new species of Rhyacoglanis is described from the rapids of Jatobal, Pará State, Brazil. This species differs from the congeners by fusing hypurals 3, 4, and 5 (vs. hypural 5 free). It also differs from the other species, except for Rhyacoglanis epiblepsis, by the color pattern with numerous dark spots on the body, short post-cleithral process, rounded pectoral and caudal fins, and incomplete lateral line. This species is known only from the type locality, which is currently flooded by the Tucuruí reservoir.

Hyla ephemera, new species, is described from the cloud forests of Cerro Las Flores in south-central Oaxaca, Mexico. We tentatively place this species in the phenetic H. bistincta group. It is most similar to H. calthula in color pattern but differs in having a greater snout–vent length, a relatively shorter snout and tibia, a relatively wider head, and a larger tympanum. We also report an additional locality record for H. calthula, previously known only from the type locality.

We perform a review of the Erythrolamprus reginae species group and putative related taxa (E. dorsocorallinus, E. zweifeli, and E. oligolepis), based on external morphology and hemipenial characters. We infer species boundaries among taxa traditionally associated with this group, recognizing two nominal subspecies (Erythrolamprus reginae reginae and E. r. macrosomus) in the species level. We propose the synonymy of E. r. semilineatus with E. reginae and recognize the validity of the related taxa, such as: E. dorsocorallinus, E. zweifeli, and E. oligolepis. In addition, two specimens occurring in the state Amapá, Brazil, are herein described as a new species. Therefore, we provide an identification key for the species of the group and discuss some of the combination of morphological features useful to delimitate the species of this group, in comparison with other representatives of the genus Erythrolamprus.

Pelidnota MacLeay, 1819 is one of the most diverse genus in Rutelina (Rutelini) and, even after broad and recent revisions, fieldwork has revealed a diversity of species yet to be known to science. Here, we describe Pelidnota silveiranetoi sp. nov. with illustrations and a map for the type locality, as well as its inclusion in a previously published identification key for the Pelidnota species. The new species is diagnosable by its color pattern (body with metallic green reflections, except on the elytra, which lack black spots), mouthpart features (galea bearing three teeth and the anterior part of the labium with an excavated surface, straight proximal margin, and the posterior part with a rounded lateral margin), and parameres (concave distal margin gradually acute and slightly divergent at the apex; straight lateral margin that is slightly sinuous at the middle; slightly corrugated proximal margin).
