“…The Allophrynidae and the Centrolenidae have been consistently recovered as sister taxa, and this clade is frequently sister to Leptodactylidae (e.g., Frost et al 2006 ; Pyron and Wiens 2011 ; Jetz and Pyron 2018 ). The lack of data for Allophryne , however, prevented the optimization of several character-states at that point of the anuran tree of life (e.g., Rada et al 2019 ; Dias et al 2020 ). Our data on the larval morphology of Allophryne ruthveni helps to shed light into the evolution of tadpoles in the Allophrynidae + Centrolenidae clade.…”

“…Dias et al ( 2020 ) enumerated 9 character states present in the buccopharyngeal cavity of centrolenids: (1) elongate buccal cavity, (2) with most structures concentrated anteriorly, (3) two pairs of infralabial papillae, (4) four lingual papillae, (5) presence of narial vacuities, (6) nares oriented longitudinally, (7) conical median ridge, (8) posterior-most pair of postnarial papilla aligned in row with median ridge, and (9) few pustulations (< 7) and papillae (< 10) on both floor and roof (Fig. 9 A, B).…”

“…The internal nares of Allophryne ruthveni are almost longitudinal; they are more angular than those of leptodactylids (e.g., Wassersug and Heyer 1988 ; Nascimento et al 2021a , b ) but not completely longitudinal as those of centrolenids (Wassersug 1980 ; Rada et al 2019 ; Dias et al 2020 ). Thus, the longitudinal orientation of internal nares is a putative synapomorphy of centrolenids.…”

“…Numerous independent studies have recovered the Allophrynidae as the sister family to glassfrogs of the Centrolenidae (e.g., Frost et al 2006 ; Guayasamin et al 2008 ; Pyron and Wiens 2011 ; Twomey et al 2014 ; Streicher et al 2018 ). Recently, there has been increased interest in understanding the evolution of reproductive, larval, and coloration traits within this group (Haas 2003 ; Hoffmann 2010 ; Delia et al 2017 ; Escalona Sulbarán et al 2019 ; Rada et al 2019 ; Dias et al 2020 ; Taboada et al 2020 , 2022 ; Montilla et al 2023 ). Documenting reproductive traits for allophrynids will contribute to our understanding of this family’s biology, as well as facilitate comparative research with Centrolenids and other frogs.…”

Frogs of the Allophrynidae are an enigmatic family from South America. To date, published information is lacking regarding this group’s reproductive biology and larval morphology. Here, we provide the first detailed description of the reproductive mode, developmental mode, and tadpole morphology for Allophryne ruthveni. We developed a captive breeding and rearing protocol for this species and then conducted a series of observations to describe aspects of its reproductive biology. In captivity, this species exhibits aquatic oviposition, where single eggs are laid ungrouped within a simple jelly capsule and are scattered free in the water column before sinking to develop on benthic substrates. We did not observe parental care nor any parental interactions with eggs post-fertilization. Tadpoles are characterized by an oval body, anteroventral oral disc, a labial tooth row formula of 2(2)/3, and a dextral vent tube. The buccopharyngeal cavity is marked by the presence of two pairs of infralabial papilla and four lingual papillae. Cranial morphology is characterized by the presence of the commissura quadratoorbital. This species possesses an additional slip of the m. rectus cervicis and of the m. levator arcuum branchialium III. We discuss our results in comparison with glassfrogs (Centrolenidae).

The Neotropical genus Atelopus is the most diverse genus of bufonids comprising 99 species. Tadpoles of these frogs are readily distinguished based on the presence of a belly sucker, used by them to stay attached to rocks in fast-flowing streams. Despite their intriguing biology, information about their anatomy is scarce and many morphological systems are unknown. We describe the buccopharyngeal cavity of five Atelopus species. The Atelopus buccopharyngeal cavity is characterized by (1) presence of a pendulum-like papillae in the prenarial arena, (2) presence of a glandular zone in the prenarial arena, (3) narial vacuities, (4) conical median ridge, (5) absence of buccal roof arena papillae, (6) absence of buccal roof pustulations, (7) single pair of infralabial papillae, (8) absence of lingual papillae, and (9) absence of pustulations in the buccal floor. We propose that characters 1, 2, and 3 are new synapomorphies for the genus. We also propose that the presence of a single pair of infralabial papillae is a synapomorphy for bufonid. Finally, we discuss the convergent evolution of gastromyzophorous and suctorial tadpoles withing anurans.

Frostius pernambucensis is a phytotelm-breeding frog with endotrophic larvae. Although the larvae were formally described, no aspect of its internal morphology is known. In this paper, we re-describe the tadpole based on a large sample, describe its internal anatomy (buccopharyngeal cavity and musculo-skeletal system), provide data on natural history, and discuss the evolution of endotrophy and phytotelma colonization. The tadpoles of F. pernambucensis are highly modified, with depressed bodies, reduced mouthparts, and long tails. Many character-states described for these tadpoles can be related to its endotrophic development. Consequence of this highly modified phenotype, we propose several novel putative synapomorphies for the genus: (1) labial tooth row formula 1/1; (2) absence of pustulation in the buccal roof and (3) floor; (4) absence of median ridge; (5) absence of lateral ridge papillae; (6) absence of secretory ridges and pores; (7) absence of filter plates; (7) m. subarcualis rectus II–IV originating on ceratobranchial III; (8) m. subarcualis rectus II–IV inserting on ceratobranchial I; (8) ventral slip of the m. subarcualis rectus I inserting on the ceratobranchial III; (9) suprarostral corpora fused to the cornua trabeculae; (10) commissura quadratoorbitalis absent; (11) cerabranchial II attached to the planum hypobranchiale; and (12) ceratobranchial III attached to the planum hypobranchiale. Finally, we also propose that the presence of a single pair of infralabial papilla could represent a synapomorphy of bufonids. The colonization of phytotelma seem to have created a selective pression on the development of F. pernambucenis, favoring the evolution of endotrophy.
