Scientists have identified a new species of miniature frog in southern Brazil, measuring less than one centimeter and exhibiting bright orange coloration. The amphibian, designated Brachycephalus lulai, is found exclusively in a small mountainous forest area known as Serra do Quiri within Santa Catarina State at elevations above 750 meters.
This frog belongs to the family Brachycephalidae (shorthead frogs). Researchers note that two closely related species have been previously documented in neighboring regions of the same mountain system. Over a seven-year period, scientists have been cataloging local populations of this genus when they discovered B. lulai.
Despite its striking appearance, the frog’s mating call was critical for detection. Males were identified through their quiet vocalizations, while females were collected randomly during field surveys. In laboratory settings, researchers conducted genetic and morphological analyses to differentiate the species from similar ones.
The name Brachycephalus lulai honors Brazilian President Luiz Inacio Lula da Silva.
“The naming of this species aims to stimulate expanded conservation efforts for Atlantic rainforests, particularly for miniature frogs endemic to Brazil,” the study states.
While B. lulai’s habitat remains relatively undisturbed and classified as “least concern” by conservation experts, other frog species in Santa Catarina State are critically endangered. Major threats include grassland burning, livestock grazing, invasive plant species, tourism, mining, and deforestation. Amphibians globally remain the most threatened class of vertebrates.
According to the research team, discussions are ongoing for establishing a federal protection zone in the region without requiring land purchases from private owners. They also anticipate that further study of shorthead frogs will enhance understanding of intraspecific variability and contribute to revisions of species boundaries.
