Thaipotamon songkhwae Tan, Naiyanetr & Yeo, 2026, sp. nov.
This taxonomic treatment validates Thaipotamon songkhwae as a new freshwater-crab species from Wat Bot District, Phitsanulok. It designates type specimens and diagnoses carapace and male gonopod characters that distinguish the species. The previously circulated name Thaipotamon phitsanulok did not meet ICZN requirements and was therefore unavailable.
