Species Description: Motta AP, Catroviejo-Fisher S, Venegas PJ, Orrico VGD, Padial JM 2012 A new species of the Dendropsophus parviceps group from the western Amazon Basin (Amphibia: Anura: Hylidae). Zootaxa 3249: 18-30.
D. frosti can be distinguished from closely related members of the D. parviceps group by its plain, light brown dorsal color contrasted with dark sides, copper iris, plain immaculate pale yellow to white venter color, lack of flash marks on groin and axillae, and absence of white spots on lips (Motta et al. 2012).
In life, during the day, dorsal surfaces present plain light brown or tan coloration and ventral surfaces exhibit pale yellow coloration. The thighs and internal region of foot are dark brown. The lateral surfaces of the body and head are dark brown, darker in groin region with a distinct white line or abrupt transition from the dorsal coloration to the lateral. Fingers 1, 2, and tip of finger 3 are pale, iris copper coloration. At night, the dorsal coloration of the species is yellow in males and pale brown in females without a contrasting color in the flanks or thigh (Motta et al. 2012).
In preservation, dorsal surfaces appear pale brown while the venter appears creamy white or iris gray (Motta et al. 2012).
Distribution and Habitat
D. frosti inhabit low vegetation around ponds in primary forest. Other Dendrosophus species that inhabit the same areas include the D. rhodopeplus (Motta et al. 2012).
Life History, Abundance, Activity, and Special Behaviors
Relation to Humans
According to phylogenetic analysis using 12S and 16S RNA genes, this species is most closely related to D. parviceps, D. brevifrons, and D koechlini; it is sister to the D. brevifrons and is a member of the D. parviceps group, although the group appears to be paraphyletic. Nonetheless the authors retain this group, recognizing its Amazonian origins and place the new species here with other Amazonian Dendropsophus. They also note that despite few new species of Dendropsophus described, a species accumulation curve for this genus is far from stabilized which suggest there are more to be discovered (Motta et al. 2012).
