Alona pectinata (Crustacea: Anomopoda; Chydoridae), a new freshwater cladoceran from southeast Mexico

A new species of the Chydorid cladoceran genus Alona is described herein from parthenogenetic females. The material was collected from several freshwater lagoons and pools in the southern portion of the Yucatan Peninsula, Mexico at an altitude less than 100 m. above sea level. The new species can be distinguished from other species of Alona by the combination of several features: a well-developed armature of the antennae postabdomen and postabdominal claw, the outer distal lobe of the first thoracic limb bears two pecten-like setae and the exopod of thoracic limb (i) has only five setae. This new taxon is related to other species of Alona described from South America and the old continent.
