Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 9 - 10; Anal soft rays: 14 - 16; Vertebrae: 39 - 41. Diagnosed from all congeners by having the origin of the dorsal fin behind the origin of the anal fin, 37-40 lateral-line scales, 16 circumpeduncular scales, and a dark spot at the base of the caudal fin. Differs from Thryssocypris smaragdinus in having the origin of the dorsal fin behind (vs. over or in front of) the origin of the anal fin and 16 (vs. 15) circumpeduncular scales, and from T. tonlesapensis and T. ornithosoma in having 37-40 (vs. 42-46) lateral-line scales and 39-41 (vs. 43-45) vertebrae. Can be further separated from T. ornithosoma by having a dark spot at the base of the caudal fin (Ref. 93051).
Collected mostly by large seines with small mesh measuring 2 mm from open water in the Chao Phraya River mainstem. Also found in current in irrigation canals. Observed to form school at the surface of the water, swimming very fast with other species such as Clupeoides borneensis, Rasbora spp., Barilius koratensis, Paralaubuca spp. and Discherodontus halei (Ref. 93051).
