Alcalus
Alcalus is a small group of frogs in the family Ceratobatrachidae.[2][3] It is the only member of the subfamily Alcalinae. Its sister taxon is Ceratobatrachinae. That means that the frogs are related to each other.[4] In English, some people call them Alcala's dwarf mountain frogs. They live in Palawan Island (the Philippines), Borneo, and the Malay Peninsula.[2] They prefer semi-aquatic microhabitats.[1]

Name
Scientists named this genus after Angel Alcala, a Filipino biologist who worked with Southeast Asian amphibians.[1]
Description
Compared to the closely related genera Cornufer and Platymantis, Alcalus are medium-sized. In Alcalus baluensis and A. mariae, male frogs are 20–37 mm (0.79–1.46 in) long from nose to rear end and females 26–43 mm (1.0–1.7 in). The head is wided. Skin is coarse, shagreened, or wrinkled in appearance. These frogs have disks on their toes for climbing, and they are very wide. These frogs have webbed skin between their toes . Male frogs have nuptial pads but no vocal sacs.[1]
