Occurrence : catalogNumber: UMTZC7648 ; Location : locality: Ikan River , Papan River ; Event : samplingProtocol: Electrofishing ; year: 2018, 2019, 2020 Native status Native species. Conservation status NE Notes New record to Kenyir Reservoir. There were two forms of Rasbora sp. collected in this study. A more common form has an incomplete mid-lateral stripe (not reaching gill opening) which is different from the real Rasbora paviana (Fig. 15 A). It has the mid-lateral line that begins to diffuse at the mid-section of the body, known as a mid-humeral diffuse patch (MDP) ( Lumbantobing 2014 ) (Fig. 15 B). One specimen displayed a unique set of characteristics: high and pointed dorsal fin (vs. rounded), long and, when adpressed, reaching beyond the base of the anal fin (vs. only half); pectoral fin long and overlapping pelvic fin (vs. not reaching the pelvic fin); pelvic fin elongated and reaching half of the dorsal fin base (vs. not overlapping) and possessing diamond-shape caudle peduncle blotch (vs. longitudinally elongated diamond) (Fig. 15 C). Due to a lack of specimens, a detailed comparison was not made at this moment.
