Worley´s Leaf Frog

Noblella worleyae is one of the few diurnal anurans at the Río Manduriacu Reserve. Calls were frequently heard from dawn (6: 00 h) to dusk (19: 00 h), but frogs stop vocalizing when approached. Individuals were found in areas with dense leaf litter and other decaying material, and at the base of large trees. The species is evasive and individuals quickly immersed between leaves and roots as an escape method. The new species is one of the more abundant amphibians at Río Manduriacu Reserve, as groups of individuals were frequently heard calling by day throughout much of the sloped reserve during expeditions. In fact, during a morning survey (6 h 20 am) a total of 13 males were heard calling along a 100 - m transect (JBM, field notes). The new species did not call with heavy rain. During sampling days in April 2017, air temperature inside the forest was 12 – 26 ° C (thermometer placed 120 cm above ground level at the base of a tree). Individuals have also been observed after sunset while conducting night transects, as sampling in October 2016, and January – February, 2018, yielded eight records between 20: 00 and 23: 05 h. However, these individuals were presumably flushed from their resting place within the leaf litter as surveyors passed by.
