The Genera of Phyllomedusine Frogs (Anura: Hylidae)

BY

WILLIAM E. DUELLMAN

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 (2_n_=26)
chromosomes. _Acris_ has _n_=11 (2_n_=22) (Cole, 1966). Members of the
_Hyla leucophyllata_, _microcephala_, and _parviceps_ groups have _n_=15
(2_n_=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
