The genus Amazophrynella Fouquet, Recoder, Teixeira, Cassimiro, Amaro, Camacho, Damasceno, Carnaval, Moritz, and Rodrigues, is represented by 12 nominal species and distributed in the Amazon region of Brazil, Bolivia, Colombia, Ecuador, Guyana, French Guiana, Peru, and Venezuela (Frost 2020). In the last eight years, ten species from this genus have been described. However, despite the wide distribution and diversity of these species, only the tadpole of Amazophrynella manaos Rojas, Carvalho, Ávila, Farias, and Hrbek from the Brazilian Amazon (Menin et al. 2014) and A. siona Rojas, Fouquet, Ron, Hernández-Ruz, Melo-Sampaio, Chaparro, Vogt, Carvalho, Pinheiro, Ávila, Farias, Gordo, and Hrbek from Ecuador have been formally described (Duellman & Lynch 1969; Rojas et al. 2018). Literature about tadpole morphology, reproduction, and bioacoustics of Amazophrynella is scarce and necessary to a comprehensive taxonomic classification (Kaefer et al. 2019). Herein, we describe the tadpole of the recently described species Amazophrynella teko Rojas, Fouquet, Ron, Hernández-Ruz, Melo-Sampaio, Chaparro, Vogt, Carvalho, Pinheiro, Ávila, Farias, Gordo, and Hrbek, found in the northeastern Amazon, in the State of Amapá, Brazil, and in French Guiana.

A new species of Passiflora is described from reforested post bauxite-mined area in the National Forest of Saracá- Taquera in the Brazilian state of Pará. The species is illustrated and its affinities with related species are discussed, and a key to the species of supersection Laurifoliae, series Quadrangulares is presented. The series Quadrangulares is composed of four species that constitute a small complex of large-flowered and large-fruited passionflowers with 3–4- angulate-winged stems that occurs naturally in the moist lowlands from Nicaragua to Brazil and French Guiana. However, among the four species of the series, Passiflora trialata is closely related to the new species by the 3-angular stems, the color and shape of sepals and petals, the 3-angular petioles and peduncles, and the single operculum.

The consumption of greens is reported as being very minor among Amazonian Indians. The authors of this article present a new review of this subject, based on fieldwork with Amerindians and other populations in different parts of the Brazilian Amazon and French Guiana. Written sources on Brazilian, Peruvian, Columbian and Venezuelan Amazon were also reviewed. The consumption of cultivated, semi-cultivated and wild species of greens was taken into account here, as the data specific to wild greens is very scarce. It is confirmed that greens are not commonly eaten among native Amazonians and that some ethnic groups do not consume them at all. The consumed species are usually young shoots of weeds or cassava leaves. Common in the Belém region are some specific aromatic plants, which have been diffused to other parts of the Amazon, together with introduced plants such as kale and coriander. Migrants from Northeastern Brazil settled in the Amazon consume some cultivated greens, especially aromatic plants. Maroons are the ones who use more greens in their diet. Native Amazonian people, who supplement agriculture with game and fish, follow a hunter-gatherer pattern, preferring wild fruit and tubers to greens.

The gigas species group of the subgenus Canthidium (Neocanthidium) is defined and described. This species group is composed of three described species [C. gigas Balthasar, 1939, Brazilian Atlantic Forest, including intrusions into Cerrado, C. bokermanni (Martínez et al., 1964), Chaco and western Cerrado in Brazil, Bolivia, Paraguay, and Argentina, and C. kelleri (Martínez et al., 1964), Brazilian Cerrado and neighbouring open areas] and three new species: Canthidium stofeli sp. nov. from the western and southern regions of the Brazilian Amazon, Canthidium feeri sp. nov. from French Guiana, and Canthidium ayri sp. nov. from the Brazilian Atlantic Forest. We present descriptions and redescriptions, illustrations, an identification key and comments on the distributions of the species of the gigas group.

ABSTRACT A new species of Paralithoxus is described from the Ajarani River, a small tributary of the Branco River basin, Roraima State, Brazilian Amazon. The genus Paralithoxus comprises species described from the Essequibo drainage in Guyana, Approuague and Maroni in French Guiana, Suriname River in Surinam, and more recently, from Jari and Amapá rivers, in Brazil. Despite occurring in a rock-bottomed fast-flowing stream as the other species of Paralithoxus, this is the first species of the genus collected at 900 m altitude, in the Serra da Mocidade highlands, an isolated and poorly accessible small mountain chain at the southern border of the Guiana Shield. The new species is distinguished from its congeners by having truncate teeth, color pattern with green spots on dark olive-brown background, alternating dark and light blotches on fins and by the pelvic fin being as long as or longer than the pectoral fin. Sex dimorphism of the species is described. Comments on morphology and osteology are provided and compared with congeners.

Praying mantises (Mantodea) are distinct for their rich diversity of cryptic adaptations. Among the many strategies, dry-leaf mimicry have evolved multiple times in unrelated lineages from different zoogeographic regions, among them the Neotropical Acanthopidae. Here we describe Metacanthops fuscum n. gen. et n. sp. based on male and female specimens from the Brazilian Amazon. The recognition of this new acanthopid lineage revealed that Acanthops amazonica Beier, 1930 (currently assigned to Metilia Stål) is a member of Metacanthops and thus we transfer this species, now referable to as Metacanthops amazonica (Beier, 1930) n. comb., redescribe the holotype, and provide new data on its distribution in Brazil and French Guiana. Metacanthops is closely related to Metilia, from which its number of forefemoral posteroventral spines, head and compound eye shape, pronotal configuration, wings features, and the entirely brown habitus of males, can distinguish it. We highlight some aspects of sexual dimorphism in Metacanthops fuscum in relation to their dimorphic cryptic strategies, where males resemble a dry leaf and females a lichenous twig. We additionally establish five recently published names under genus Metilia as nomina nuda.

The common green racer Philodryas viridissima (Linnaeus, 1758) is an arboreal and terrestrial snake species broadly distributed in southern Venezuela, Colombia, Ecuador, Peru, Bolivia, Guiana, Suriname, French Guiana, Paraguay up to Argentina, and most of Brazil. In this study, we report the first record of P. viridissima in the state of Acre, Brazil, in the Chico Mendes Extractive Reserve. This record expands the species distribution in 280 km to the southwest of Boca do Acre, state of Amazonas, which was the nearest record of this species in Brazilian Amazon until now.

Early diagnosis and treatment are fundamental to the control and elimination of malaria. In many endemic areas, routine diagnosis is primarily performed microscopically, although rapid diagnostic tests (RDTs) provide a useful point-of-care tool. Most of the commercially available RDTs detect histidine-rich protein 2 (HRP2) of Plasmodium falciparum in the blood of infected individuals. Nonetheless, parasite isolates lacking the pfhrp2 gene are relatively frequent in some endemic regions, thereby hampering the diagnosis of malaria using HRP2-based RDTs. To track the efficacy of RDTs in areas of the Brazilian Amazon, we assessed pfhrp2 deletions in 132 P. falciparum samples collected from four malaria-endemic states in Brazil. Our findings show low to moderate levels of pfhrp2 deletion in different regions of the Brazilian Amazon. Overall, during the period covered by this study (2002-2020), we found that 10% of the P. falciparum isolates were characterized by a pfhrp2 deletion. Notably, however, the presence of pfhrp2-negative isolates has not been translated into a reduction in RDT efficacy, which in part may be explained by the presence of polyclonal infections. A further important finding was the discrepancy in the proportion of pfhrp2 deletions detected using two assessed protocols (conventional PCR versus nested PCR), which reinforces the need to perform a carefully planned laboratory workflow to assess gene deletion. This is the first study to perform a comprehensive analysis of PfHRP2 sequence diversity in Brazilian isolates of P. falciparum. We identified 10 PfHRP2 sequence patterns, which were found to be exclusive of each of the assessed regions. Despite the small number of PfHRP2 sequences available from South America, we found that the PfHRP2 sequences identified in Brazil and neighboring French Guiana show similar sequence patterns. Our findings highlight the importance of continuously monitoring the occurrence and spread of parasites with pfrhp2 deletions, while also taking into account the limitations of PCR-based testing methods associated with accuracy and the complexity of infections.
