A new species of rasborin fish discovered

28 May 2014. Scientists in NUS discovered a new species of rasborin fish in Indonesia.

Dr TAN Heok Hui from the Department of Biological Sciences in NUS has just described a new species of rasborin fish. The new specie, Brevibora exilis, is found in the Kahayan and Sebangau basins of Kalimantan Tengah, Borneo, Indonesia (see Figure).  This specie is distinguished from its congeners, B. cheeya and B. dorsiocellata, by its circumpeduncular scales, anterior outline of dorsal-fin blotch, and relatively more slender body. It is further distinguished from B. cheeya by the incomplete lateral line with fewer perforated scales, a shorter head, a smaller caudal peduncular depth, a shorter caudal peduncule, a smaller prepectoral length, and shorter dorsal fin. In addition, it is also further distinguished from B. dorsiocellata by having more scales along the lateral-line row.
