Ingerana rajae, new species, is found in Bukit Baka-Bukit Raja National Park, West Kalimantan, Borneo, and is characterised by its large size, dorsum covered with tubercles, no clear distinction of the dorsolateral area, tympanum completely concealed under skin, and fi ngers and toes ornamented with widely enlarged tips with a circum-marginal groove. Toes are completely webbed to the base of enlarged tips, except for the outer side of penultimate phalanx of the fourth toe, which is essentially free from webbing. The species is contrasted with other members of the genus and some taxonomic confusion is discussed and clarifi ed. [ABSTRACT FROM AUTHOR]

Occidozyga semipalmata is found to be unique based on the fl attened fi nger and toe tips that lack circum-marginal grooves and in having a tongue with rounded tip. Another form, O. tompotika new species, is found at Mount Tompotika, Eastern Peninsula of Sulawesi, appears to be closely related to species from the Wallacean region and the Philippines. This is a medium sized species, toes and fi ngers with larger fl attened tips lacking a circum-marginal groove and more extensive toe webbing compared to O. semipalmata. However these two species, together with O. fl oresiana, are retained within the genus and not assigned to Ingerana because they have most characters allied to the genus, especially by the lack of external tympanum and having a single bony protuberance at the lower jaw tip.
