Betta hendra - A new species of fighting fish (Teleostei: Osphronemidae) from Kalimantan Tengah (Borneo, Indonesia)

Abstract

Betta hendra spec. nov. is described from Kalimantan Tengah, Borneo, Indonesia. It is a bubble-nesting fighting fish of the B. coccina species group. The new species differs from the other members of the group by a bright greenish iridescent colour on the flanks and unpaired fins. It is distinguished from its geographical neighbour species B. uberis by a lower number of dorsal-fin rays (10-12 versus 14-17).
