Updated Checklist of the Freshwater Shrimps (Decapoda: Caridea: Atyidae) of Mindoro Island, the Philippines, with a Description of a New Species of Caridina

Following recent expeditions to Mindoro Island, the Philippines, numerous samples of atyid shrimps were collected and then studied in an integrative taxonomy framework. Atotal of 16 species belonging to 4 genera are hereby reported, including 8 new records for the island and/or the Philippines: Atydina atyoides, Caridina bruneiana, C. celebensis, C. elongapoda, C. papuana, C. parvirostris, C. typus, C. zhujiangensis, and one new species, Caridina leptopoda sp. nov.

Sequences of 16S rRNA have been produced for all of the species and taxonomical notes are provided. To account for the morphological variability across its range, C. bruneiana Choy, 1992 is herein re-described based on specimens from Mindoro. All of the species reported here from Mindoro have small eggs and are considered amphidromous, which suggests that they all potentially occur in other localities.

This contrasts with other islands of the Philippines such as Bohol or Luzon where endemic species with large eggs can be found.
