(Revision) On the small to medium size fish of the genus Rasbora

Very recently, a study of the phylogeny of the cyprinid genus Rasbora by researchers from the Swedish Museum of Natural History in Stockholm has resulted in the establishement of four new genera namely Brevibora, Kottelatia, Rasbosoma dan Trigonostigma to accomodate some fishes of the genus Rasbora.

I've yet to see and read the paper [For more information, see the paper: Liao, T-Y, SO Kullander & F Fang (2010) Phylogenetic analysis of the genus Rasbora (Teleostei: Cyprinidae). Zoologica Scripta 39, pp. 155–176.] but here is some update that related to fishes found in Peninsular Malaysia (at least!)

Brevibora
(Latin brevis=short and -bora from Rasbora)
This genus consists of only one species, B. dorsiocellata which found in Terengganu, P. Malaysia.

Kottelatia
Named after Swiss ichthyologist Dr. Maurice Kottelat
This genus includes only a single species (K. brittani) but not reported in P. Malaysia.

Rasbosoma
Derived rom Rasbora and the Greek soma=body)
This genus includes only one species i.e. R. spilocerca found in Thailand.

Trigonopoma
(Greek trigonos=triangle and poma=lid)
This genus has two species: T. gracile (formerly Rasbora gracilis) and T. pauciperforatum (formerly Rasbora pauciperforata). Both species found in peat and acid water swamps in P. Malaysia.
