The Genera of Phyllomedusine Frogs (Anura: Hylidae)

One of the most distinctive phyletic lines among the diverse Neotropical hylid frogs is composed of a group of 40 species placed in the genus Phyllomedusa (Funkhouser, 1957) or in two or three different genera (Goin, 1961; Lutz, 1966). These species differ from all other Neotropical hylids by possessing a vertical, instead of horizontal, pupil. The only other hylids having a vertical pupil belong to the Papuan genus Nyctimystes. Goin (1961) erroneously stated that Nyctimantis and Triprion have vertical pupils. Although limited information is available on the cytotaxonomy of hylids, the data show that phyllomedusine species have n=13 (2n=26) chromosomes. Acris has n=11 (2n=22) (Cole, 1966). Members of the Hyla leucophyllata, microcephala, and parviceps groups have n=15 (2n=30), Gastrotheca ceratophrys has a haploid number of 14, the Papuan hylid genus Nyctimystes and all but one of the Australo-Papuan Hyla for which the numbers are known have a haploid number of 13, and all other New World hylids studied have n=12 (2n=24) (Duellman and Cole, 1965; Duellman, 1967). ......Buy Now (To Read More)
