Euparkerella robusta

The body is robust. Adult males measure 17.2–21.5 mm (0.7–0.8 in) in snout–vent length. It is a large member of its genus; it differs from the other large species, Euparkerella tridactyla, by its longer fingers.^[3]

The male advertisement call consists of a single note comprising 5–8 long pulses repeated periodically. The pulses are relatively long and have a whistle-like character (as opposed to short snaps in other Euparkerella). The call duration is 1.3–2.2 seconds and the dominant frequency is 2.9–3.2 kHz.^[3]

Euparkerella robusta occurs in leaf litter in primary and secondary forest. Development is direct^[1] (i.e., there is no free-living larval stage^[4]).

It is reasonably common at the type locality. Habitat loss caused by agriculture, logging, and human settlement is a concern. At time of the most recent IUCN assessment, it was not known to occur in any protected area.^[1] However, the locality in Atílio Vivacqua, Serra das Torres,^[3] could overlap with the Serra das Torres Natural Monument.
