On a collection of freshwater and estuarine crabs (Crustacea: Brachyura) from Mindanao Island, the Philippines.

The brachyuran fauna of the large southern Philippine island of Mindanao is poorly known, with only a few freshwater and estuarine crab species described or recorded in the last 30 years. Renewed interest in crab biodiversity has led to recent, small-scale surveys (2016-2019) of freshwater and estuarine habitats in various localities in Mindanao, which have yielded a good diversity of brachyuran crabs. As a result, a total of 26 species of brachyuran crab, representing 6 families (Hymenosomatidae, Oziidae, Gecarcinidae, Sesarmidae, Varunidae, and Ocypodidae), are reported here.
