Trigonostigma somphongsi is a species of ray-finned fish in the genus Trigonostigma . It is endemic to Thailand. It is threatened by habitat loss. [1]
Trigonostigma somphongsi is probably endemic to the lower Mae Klong Basin near Ratchaburi Province, its type locality being given as only 'Thailand'. Balantiocheilos melanopterus and Ambastaia sidthimunki , two other species originally found in the area have been extirpated due to the modification of river habitats. This species most likely prefers deeply vegetated (therefore dark) river habitats of a neutral to weakly acidic pH, obstructed by organic materials that exude tannin in decomposition. [3]
The specific name honours Thai fish explorer and aquarium trader Somphong Lek-aree, the first discoverer of this species of fish. In early 2012, a group of Thai scientists was conducted a field survey of the natural habitat of this species of fish in deep water rice fields in Nakhon Nayok Province near Bangkok. [4]
