  The first record of Trigonostigma somphongsi (Meinken, 1958), a critically endangered species, in its natural habitat of Thailand (Cypriniformes Cyprinidae)

  ABSTRACT
  A population of a critically endangered Trigonostigma somphongsi (Meinken, 1958) has been discovered in a deepwater rice field, floodplain of Bangpakong Basin, Nakhornnayok 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.
