Stereocyclops (common name: Brazilian dumpy frogs) is a small genus of microhylid frogs.[2][4] It is endemic to the Atlantic forest of eastern Brazil.[2] Molecular phylogeny suggests that it is sister taxon to the clade containing Dasypops and Myersiella.[5]
Description[]
Stereocyclops can be defined by features of its osteology. In the skull, palatine bone is present, as is the posterior part of . The clavicle is fully developed and long. Furthermore, the dorsal coloration is light and sharply separated from the dark ventrum by a light line. The head is flattened and the mouth is relatively large.[3] Notice, however, that at the time of this description, the genus was monotypic and Hyophryne was considered a separate genus;[3] a thorough morphological study of the genus as presently understood is lacking.[6]
Beheavior[]
One species, Stereocyclops parkeri, is known to show defensive behavior that may enhance its cryptic appearance, giving an impression of a casually dislodged leaf: when an individual is disturbed, it makes a short leap, landing with its legs stretched backwards. It will then remain still, sometimes as long as 30 minutes, although it may also move a little forward with a quick movement of the feet, resembling a flicked leaf.[7]
Species[]
There are four species in the genus:[2][4]
