<em>Aparasphenodon bokermanni</em> is a poorly known casque-headed tree frog found in São Paulo and Santa Catarina, southern Brazil. Here we provide two new records, one from Joinville, northeastern Santa Catarina, and the first record from Santa Catarina Island, Brazil, which extends to the south the range of the genus by approximately 150 km.

Abstract:

Corythomantis greeningi is a casque-headed frog that occurs in xeric and sub-humid regions of northeastern Brazil. Individuals are often found on rocks on banks of temporary streams or in ponds upon “lajedos”. Suctorial tadpoles are often found clasping to the rocks in the streams so as not to be dragged by the current; therefore, they have modified external and internal morphology. Here, we describe the internal oral anatomy and the chondrocranium of the tadpole of C. greeningi and compare it to the available descriptions of Lophyohylinae and other suctorial tadpoles.

Abstract:

Casque-headed tree frogs (Lophyohylini) can have a very large and distinctive head characterised by hyperossification of their cranial skin. This type of skull was primarily associated with phragmosis, a behaviour in which the frog enters holes backwards and seals them with its head to prevent water loss in challenging environments. Further investigations revealed that hyperossification also gives rise to bony spines interspersed with skin poison glands. These peculiar anatomical features of the head make it challenging for predators to prey on the frogs in phragmosis. When bitten on the head,

It is considered of wide occurrence in the Caatinga (Rodrigues, 2005) and is also found in some areas of the Cerrado, the Brazilian savannah (Colli et al, 2002). C. greeningi is characterized by its distinctive and flattened head, in which the helmet-shaped skull together with the head skin form a single coossified structure. This type of head has been associated with phragmosis (a term used for animals which close holes u

Therefore, the genus Nyctimantis currently consists of seven described species: N. arapapa (Pimenta, Napoli & Haddad, 2009); N. bokermanni (Pombal, 1993); N. brunoi (Miranda-Ribeiro, 1920); N. galeata (Pombal, Menezes, Fontes, Nunes, Rocha & Van Sl

In this paper, we assessed the anatomy of vocal sacs in representatives of the Lophyohylini, described eight discrete characters and studied their evolution. We inferred that dorsolateral projections of the vocal sacs were already present during the early evolution of the tribe. Subsequently, they reached surprising volumes in some species, whereas in others they were notably reduced. We inferred

Abstract:

Non-avian reptiles, unlike mammals and birds, have undergone numerous sex determination changes. Casque-Headed Lizards have replaced the ancestral XY system shared across pleurodonts with a new pair of XY chromosomes. However, the evolutionary forces that triggered this transition have remained unclear. An interesting hypothesis suggests that species with intermediate states, with sex chromosomes but also thermal-induced sex reversal at specific incubation temperatures, could be more susceptible to sex determination turnovers. We contrasted genotypic data (presence/absence of the Y chromosome)

Abstract Almost all lizard families in the pleurodont clade share the same XY system. This system was meticulously studied in Anolis carolinensis, where it shows a highly degenerated Y chromosome and a male-specific X chromosome dosage compensation mechanism. Corytophanids (casque-headed lizards) have been proposed as the only family in the pleurodont clade to lack the XY system. In this study, we worked with extensive genomic and transcriptomic data from Basiliscus vittatus, a member of the Corytophanidae family that inhabits the tropical rainforests of Mexico.

Abstract:

The tadpole of Itapotihyla langsdorffii is described and illustrated. Morphological data are compared with available information on tadpoles of casque-headed frogs occurring in the Atlantic Rainforest (genera Aparasphenodon and Trachycephalus), and also with Osteocephalus. The ontogenetic shift in tooth row formula and the great similarity on tadpole external morphology among these genera do not allow the use of the examined larval characters on generic diagnoses. However, we present some juvenile characters which may support the validity of Itapotihyla. The confrontation of the hypotheses con

ABSTRACTParreira. I.P. 2025. Age structure and size variation in three closely related species of casque‐headed frogs of the genus Trachycephalus (Hylidae: Lophyohylini)—Acta zoologica (Estocolmo). This study provides insights into longevity, sexual maturity and growth curves in closely related casque‐headed treefrogs distributed across distinct Brazilian biomes. Age estimation based on the counting of lines of arrested growth (LAGs) in bone tissue revealed a longevity of 6 years in Trachycephalus nigromaculatus and T. atlas, which is uncommon among Neotropical species.
