Abstract
We describe Phyllodytes gravata sp. nov., a new species of bromeligenous treefrog from the Atlantic Forest of southern Bahia, Brazil. The new species is characterised by its small body size (males 19.5–22.0 mm snout-vent length; female 23.5 mm), a rounded snout with an apical tubercle, an inconspicuous row of tubercles along the tarsus, with a single prominent tubercle at the tibiotarsal articulation, a dorsolateral brown stripe, and an advertisement call composed of long series of pulsed notes (22–34 notes/call; call duration 5.2–7.3 s; dominant frequency 2.75–3.83 kHz). The species is currently known from only two nearby localities within the Central Corridor of the Atlantic Forest (CCAF), in the municipality of Porto Seguro, district of Trancoso, Bahia, a major tourist destination, where it inhabits bromeliads in sandy-soil ecosystems known as mussunungas. Its apparently microendemic distribution and strict association with bromeliads render it vulnerable to several anthropogenic threats, such as bromeliad harvesting, increasing tourism, urbanisation, and agriculture. This discovery underscores the persistent hidden diversity of the CCAF and reinforces the urgent need to protect its highly special microhabitats.
