Phrynomedusa appendiculata (Lutz, 1925)

Open encyclopedia reference

Phrynomedusa appendiculata, the Santa Catarina leaf frog, is a species of frog in the subfamily Phyllomedusinae. It is endemic to Brazil, where it is only known from the southern Atlantic Forest. This frog is classified as critically endangered on the IUCN Red List. It is thought to be a very rare and declining species. After 1970, no further sightings of the species were made until late 2011, when it was rediscovered near Santo André in the state of São Paulo, marking the first observation of the species in over 41 years; these results were published in a 2022 study. The factors for its initial disappearance remain unclear, although it may have to do with chytridiomycosis and habitat loss associated with agriculture and coal mining, including air pollution. The Santo André site is over 250 kilometers away from its type locality near São Bento do Sul in Santa Catarina, and despite immense growth in citizen science efforts over the following decade, the species has not been recorded at any other sites aside from Santo André.
