Schindler, I. and S. van der Voort. 2012. Re-description of Betta rubra Perugia, 1893 (Teleostei: Osphronemidae), an enigmatic fighting fish from Sumatra. Bulletin of Fish Biology 13(1/2): 21-32
Betta rubra, occurring from Meulaboh to Sibolga in north-western Sumatra, is formally re-described based on freshly collected preserved and live specimens. The species can be differentiated from other members of the genus by the combination of the following characters and character states: an iridescent light blue patch at pectoral fi n origin, alternating black bars and red blocks ventrolaterally on the fl ank, presence of a dark triangular patch below the eye, absence of red twin bars on the opercle when preserved. Based on the differential diagnosis B. rubra is herein removed from the Betta foerschi species group, in which it was
tentatively placed, and transferred into its own group. Uncertainties regarding its distribution are resolved. Biogeography and possible speciation of B. rubra are briefly discussed.
Hmm...and check out that second author. Congratulations mate!
