Isthmohyla zeteki, or Zetek's treefrog, is a species of frog in the family Hylidae native to the Cordillera Central and Cordillera de Talamanca of Costa Rica and western Panama at elevations of 1,200–1,800 m (3,900–5,900 ft) asl.[1][2][3]

Description

Isthmohyla zeteki are small treefrogs, with males growing to 24 mm (0.94 in) and females to 27 mm (1.1 in) snout–vent length. Dorsal colouration varies from yellowish tan to green, whereas ventral surface is translucent white. Iris is dull red, red-brown, or bronzy pink.[3]

The male advertisement call lasts about four seconds and consists of five pulsed notes. The second and third note are the shortest, and the two last ones are the longest, but with a lower pulse rate.[4]

Habitat and conservation

Its natural habitats are humid premontane and lower montane forests. It is a canopy species living in bromeliads, where also the tadpoles develop. It can also occur in modified habitats such as pastures, provided that suitable trees with bromeliads remain.[1] The species has also been recorded in a large terrestrial tank bromeliad.[4]

Costa Rican populations appear to be stable in suitable habitat (although estimating density of these arboreal frogs is difficult). In the Panamanian part of its range it is probably impacted by habitat loss.[1]
