Noted Swiss ichthyologist Maurice Kottelat has described a new species of Rasbora from Tarakan Island, off the eastern coast of Borneo.
The description of the new species, named Rasbora dies, is published in the latest issue of Ichthyological Exploration of Freshwaters.
Rasbora dies is distinguished from other members of the genus in having a combination of a reticulated pattern on the middle of the flank, a small diamond-shaped spot at the base of the caudal fin, and a complete lateral line.
The species is named after the Latin for a day (dies).
This species superficially resembles R. semilineata, but the latter lacks the reticulate pattern on the body and a complete lateral line.
No picture of the fish was available for publication.
