“…In its original description, P. somuncurense was placed within the genus Telmatobius , and in this context, the presence of iris projections (among others) was highlighted as a diagnostic character (Cei, ). Following Lutz () those structures were identified as meniscus. Lynch () erected the monotypic genus Somuncuria for the species S. somuncurensis , but he was unable to specify its sister‐group relationship.…”

“…Duellman and Trueb (1986) described the amphibian eye morphology and mentioned that anurans with horizontal pupils possess dorsal and ventral pupillary nodules that are correlated with pupil contraction. Miranda-Ribeiro (1920, 1926 coined the term "meniscus" for a discoid lobule projecting from the upper margin of the iris, and this denomination was used by others to describe a similar structure (e.g., Barrasso, Cotichelli, Alcalde, & Basso, 2013;Basso, 1998;Cei, 1969Cei, , 1970Izecksohn, 1983;Lutz, 1929Lutz, , 1943. Nevertheless, not all anurans have the same type of meniscus.…”

“…Nevertheless, not all anurans have the same type of meniscus. Cei (1969Cei ( , 1970 reported that Pleurodema somuncurense has a dorsal and a ventral meniscus, but apparently, Cyclorhampus and Zachaenus possess only a dorsal meniscus of different sizes (Izecksohn, 1983;Lutz, 1929Lutz, , 1943Miranda-Ribeiro, 1920, 1926. Basso (1998) described the presence of an enlargement of the ventral pupillary nodule in Atelognathus ceii.…”

Vision is one of the main sensory systems in amphibians, and the eye structure is highly associated with habitat conditions. The ontogeny, as well as the adult structure, of the eye has been studied in only a few species. The life change after metamorphosis is accompanied by changes in the visual environment. The aim of this work is to describe the eye ontogeny of Pleurodema bufoninum and to compare it with that of Pleurodema somuncurense. Specimens of both Pleurodema species were processed for histology analysis at different stages of development, including the tadpole, postmetamorphic, and adult forms. Eyes in both Pleurodema species are composed of the 3 tunics, tunica fibrosa, tunica vasculosa, and tunica interna, and the lens. Additionally, in both, the iris presents a projection on its dorsal and ventral free ends that screens the cornea. This structure has been reported in the eye of several anuran species and is called the umbraculum, meniscus or pupillary nodule. Our results show that the structures related to light capture (retina and lens) appear early in larval life, while the components of the terrestrial-life eye (scleral cartilage, specialized cornea, eyelids, nictitating membrane, and Harderian's gland) do not develop until the metamorphic climax, when the tadpole leaves the water. The adult eyes of P. bufoninum and P. somuncurense are very similar in structure and development.

Here, we review the species of anuran amphibian from the Serra da Bocaina National Park and its buffer area, in the Atlantic Forest of southeastern Brazil, comparing the data from a recent survey with museum records. We surveyed adult and larval anurans in ponds, marshes, and streams discontinuously from May 2008 to January 2011. In total, 63 anuran species were previously known to occur at the Park and its surrounding buffer area. In our survey, we recorded 46 species, of which five represented new records, and 22 appeared only in the historical list. Seven topotypic populations were not found in the present study. We suggest that conservation strategies for anurans in the Serra da Bocaina should also consider the surrounding areas that are subjected to anthropogenic pressure, due to the high diversity recorded, high altitudinal variation in species distribution, and various vegetation formations.

“…These disk-like glands were also used as a genus characteristic of cycloramphids by Lutz (1929). In this work, we elect the designation iliac gland because of its localization, i.e., over the iliac muscle of the abdominal inferior region.…”
