Since I do not have access to Rev. Brasil Biol., I would appreciate it if someone could tell me what characters distinguish Hylomantis from other Phyllomedusines.

Has anyone ever seen a photo of a Hylomantis?

Thanks,
Harold

Hi,

maybe this helps:

Notes on the phyllomedusine frog Hylomantis aspera Peters, 1872 (Anura, Hylidae)

Hylomantis aspera was described by Peter in 1872 and the syntipes were probably collected at Caravelas, State of Bahia. After that, just a single specimen was collected at Itabuna (BA), in 1972. Recently, others specimens were found and the distribution range of H. aspera is now extended to the north ca. 85 km, comprising a large portion of the southern coast of Bahia. On this opportunity, new informations about habitat, morphology, color in life and advertisement call were obtained. Specimens were always found perched on leaves at the marginal vegetation of temporary ponds, from where males call, inside undisturbed or secondary forest patches.
Glandular ridges are observed from the external margins of arms to the fourth finger and on the external margins of thighs, tibias, and fifth toes. General color pattern is apple-green or purple on dorsum, with a few scattered white warts. Fingers, toes, upper-arms, flanks, hidden portions of thighs and tibias and ventral surfaces of legs are orange, and venter is light-pink. Glandular ridges on arms and legs are white. The advertisement call consists of one note with frequencies
between approximately 0.95 and 4.22 kHz. The mean duration of the advertisement call was 0.06 s (SD = 0.01, range = 0.052-0.067, N = 12 vocalizations of two males), and the mean intercall
interval was 2.08 s (SD = 1.00, range = 1.30-3.16, N = 12 vocalizations of two males). Mean dominant frequency was 2.03 kHz.

Thanks Wulf.

That certainly helps with H. aspera. Unfortunately, it doesn't seem to do much in regard to defining the genus.

Hi Harold,

sorry I can't help more, but I'm not really into Amphibians. But you perhaps like to check out the AMNH research page. I know that Linda Ford and other staff members of the Herpetological Division are doing research on frogs.

Cheers,
Wulf
