True toads of the genus Rhinella are among most common and diverse group Neotropical anurans. These widely distributed throughout South America, inhabiting a great diversity environments ecoregions. Currently, however, is defined solely on basis molecular characters, it lacks proper diagnosis. Although some phenetic species groups have traditionally been recognized within Rhinella, monophyly them rejected in previous phylogenetic analyses, many remain unassigned to these poorly groups....
Abstract Anuran vocal sacs are elastic chambers that recycle exhaled air during vocalizations and present in males of most species frogs. Most knowledge the diversity relates to external morphology; detailed information on internal anatomy is available for few groups Frogs family Hylodidae, which endemic Atlantic Forest Brazil adjacent Argentina Paraguay, have three patterns sac morphology—that is, single, subgular; paired, lateral; absent. The submandibular musculature structure mucosa (the...
The most ventral muscles of the head (the mm. submentalis, intermandibularis, and interhyoideus) provide support to gular region lift buccal floor during ventilation feeding. These show limited variation in gnathostomes, but Anura they exhibit a surprising diversity. few studies that have explored this character system highlighted its potential as source phylogenetic information. In paper we diversity studying specimens 567 anuran species reviewing published data cover total 1321 species,...
Photoreceptor oil droplets (ODs) are spherical organelles placed most commonly within the inner segment of cone photoreceptors. Comprising neutral lipids, ODs can be either non-pigmented or pigmented and have been considered optically functional in various studies. Among living amphibians, were only reported to occur frogs toads (Anura), while they absent salamanders caecilians. Nonetheless, limited understanding their taxonomic distribution anurans impedes a comprehensive assessment...
Abstract Vocal sacs are among the most conspicuous features of anurans and particularly striking in casque-headed treefrogs (Hylidae: Hylinae: Lophyohylini) with their wide array morphologies. In this paper, we assessed anatomy vocal representatives Lophyohylini, described eight discrete characters studied evolution. We inferred that dorsolateral projections were already present during early evolution tribe. Subsequently, they reached surprising volumes some species, whereas others notably...
The eyes of frogs and toads (Anura) are among their most fascinating features. Although several pupil shapes have been described, the diversity, evolution, functional role in anurans received little attention. Studying photographs more than 3200 species, we surveyed described morphological variation, tested correlation with adult habits diel activity, discuss major evolutionary patterns considering iris anatomy visual ecology. Our results indicate that is a highly plastic structure, seven...
Abstract Vocal sacs are present in most species of frogs and the product interaction three elements: gular skin, superficial submandibular musculature an internal mucosa derived from buccal floor. In this paper, we surveyed structural diversity vocal sac microhylids related families 109 exemplar species, including 11 13 currently recognized subfamilies. We defined five characters to anatomical histological properties m. interhyoideus, as well relationship muscle mucosa. describe a...
Abstract Cascades and fast-flowing streams impose severe restrictions on acoustic communication, with loud broadband background noise hampering signal detection recognition. In this context, diverse behavioural features, such as ultrasound production visual displays, have arisen in the evolutionary history of torrent-dwelling amphibians. The importance vocal sac multimodal communication is being increasingly recognized, recently a new display has been discovered: unilateral inflation paired...
Abstract Naupactini is a tribe of Neotropical broad‐nosed weevils highly diverse in South America. This group includes several parthenogenetic species, some them harmful for agriculture and invasive around the world. Although hypotheses based on polyploidy hybridization have been proposed to explain origin parthenogenesis weevils, infection with bacterium Wolbachia pipientis may be involved reproduction species. In this contribution, we studied role reproductive biology Pantomorus...

 The vocal sacs of frogs are elastic structures responsible for the circulation air during vocalization, amplifying sounds produced by these animals multimodal communication. Vocal present a wide array morphologies among species and may be single, paired, or absent in adult males. Most studies on Anura deal with their external morphology, not internal structure, which has been explored only handful species. aim this study was to assess sac structure three hylid species, Dendropsophus...
Resumen: Una publicación reciente reportó al hílido endémico del Bosque Atlántico Trachycephalus mesophaeus para la ecoregión Chaqueña en Argentina. En este trabajo, analizamos el espécimen de referencia y demostramos que se trata un ejemplar incorrectamente determinado microhílido asiático Kaloula pulchra , una especie comercializada a nivel mundial. De esta forma, no existe evidencia considerar T. está presente Abstract: A recent publication reported the Atlantic Forest endemic hylid for...
