We present observations on the São Tomé Island endemic Hyperolius thomensis which indicate that it is one of the few African treefrogs known to utilize phytotelmata (tree holes) forbreeding. Ourfield work and observations strongly suggest that this island giant is restricted to primary forest, remnants of which are usually at higher elevations or inaccessible areas of São Tomé Island. Our locality data and field observations in a number of circumstances are not congruent with those of Loumont (1992). An examination of the data associated with her collections housed in the Natural History Museum of Geneva reveals that her data are not specific with regard to individual specimens and dates and, as a result, the status and distribution of the amphibian species on both islands may have been misinterpreted. We note that females of the endemic ranine ranid frog, Ptychadena newtonii, attain snout-vent lengths greater than other members of the genus, and that this species should therefore be considered an island giant. We describe and illustrate for the first time the males of Africa’s largest treefrog, the Príncipe Island endemic Leptopelis palmatus, provide figures illustrating the range of male and female color pattern polymorphism and comment on adult size dimorphism and size at metamorphosis.
The endemic hyperoliid treefrogs of São Tomé and Príncipe currently recognized as Nesionixalus thomensis (Bocage, 1986) and N. molleri (Bedriaga, 1892) are re-examined. The results of two molecular analyses indicate that these taxa are closely related to each other (monophyletic) but nest within the genus Hyperolius. Acomparison of the morphological character states used by Perret (1976; 1988) to erect the genus Nesionixalus from within Hyperolius Rapp with a broad range of Hyperolius species reveals that most of these are not unique to the island endemics; all except the characters of size and digital tip shape are distributed among a number of other species within the latter genus. Nesionixalus Perret, 1976 is returned to the synonymy of Hyperolius Rapp and Nesionixalus thomensis and N. molleri to Hyperolius thomensis Bocage and H. molleri Bedriaga, respectively.

In this study, we describe the bird collection from the Democratic Republic of São Tomé and Príncipe, which was fully taxonomically checked and georeferenced. The IICT bird collection contains 5598 specimens, of which 559 are from São Tomé and Príncipe, representing 85 taxa, including 19 endemic species and 13 endemic subspecies of birds. The specimens were collected between 1946 and 1973, although 43% of the records are from 1954 and 45% are from 1970. The geographic distribution of samples covers the whole territory, with a higher number of records from São Tomé than from Príncipe. The districts with highest number of records are Pagué (equivalent to Príncipe Island), and Água Grande and Mé-Zochi on São Tomé. Despite the relatively low number of specimens per taxon, the importance of the collection is considerable due to the high number of endemic and threatened species represented. Furthermore, it adds valuable information to the GBIF network, especially for a country whose two islands are each an Endemic Bird Area and for which substantial gaps in ornithological knowledge remain.
