The morphology of the new species resembles C. sumatrensis, from which it differs in possessing a shorter rostrum with fewer dorsal teeth, a small number of very large-sized eggs, and a greatly reduced posteromedian projection on the distal end of the telson. The molecular evidence of the mitochondrial 16S rRNA gene also supports the species status of the newly described species. This is the fifth endemic species of Caridina known from Thailand.Agricultural and Biological SciencesCaridina maeklongensis, a new landlocked freshwater shrimp species (Crustacea: Decapoda: Atyidae) from the Mae Klong Basin, ThailandArticleSCOPUS10.26107/RBZ-2024-00332-s2.0-8521043319923457600
