| Habitat of Trigonostigma somphongsi in a deepwater rice field, in the flood plains of Nakhon Nayok River, Bangpakong Basin, Nakhon Nayok Province, central Thailand. Trigonostigma somphongsi were found in a mixed school with many other small cyprinids, was often led by Rasbora borapetensis (the strongest swimmer), then followed by Amblypharyngodon chulabhornae with Boraras urophthalmoides (smallest species) and T. somphongsi at the tail of the school

ABSTRACT
A population of a critically endangered Trigonostigma somphongsi (Meinken, 1958) has been discovered in a deepwater rice field, floodplain of Bangpakong Basin, Nakhon Nayok Province, central Thailand. The population was the first record of this species in its natural habitat since its description by Meinken in 1958. The species appeared to be a seasonal horizontal migration species, since it migrates to breed in the floodplain during the rainy season between July and November and migrates back into the main channel during the dry season.
KEY WORDS: Trigonostigma somphongsi; Cyprinidae; Bangpakong; Thailand.
