[Ichthyology • 2008] Puntius kelumi • a new species of cyprinid fish (Teleostei: Cyprinidae) from Sri Lanka

Puntius kelumi, new species, is described from south-western Sri Lanka. It is distinguished from all other Sri Lankan and Peninsular-Indian Puntius by having the last unbranched dorsal-fin ray smooth; body depth 28.6-35.5 % of SL; rostral barbels absent; maxillary barbels present, about as long as eye diameter; 20-23 lateral-line scales on body; .... scales in transverse line from mid-dorsum to pelvic-fin origin; and sides of head and body of breeding males rough, extensively tuberculated. Puntius layardi Günther is apparently a valid species from Sri Lanka, but has not been observed in the wild since 1868. Leuciscus binotatus Blyth, its replacement name Barbus tetraspilus Günther, and its junior objective synonym B. innominatus Day, remain species inquirendae.

[Ichthyology • 2008] Puntius kamalika • a new species of barb (Teleostei: Cyprinidae) from Sri Lanka | former Sri Lankan Puntius amphibius

Abstract
Since its first record from the island in 1912, the barb Puntius amphibius Valenciennes has regularly featured in Sri Lanka’s ichthyofaunal inventories. Recent work has shown, however, that the name P. amphibius should be reserved for a species originally collected from Bombay, India, and described by Achille Valenciennes in 1842, now known only from its lectotype. The Sri Lankan fish hitherto known by this name is an undescribed species. Puntius kamalika, new species, is distinguished from all Sri Lankan and peninsular-Indian congeners by having (in addition to a suite of mensural characters) ½4/1/2½ scales in transverse line between mid-dorsal scale row and pelvic-fin origin and lacking any prominent markings on fins and body in both living and preserved examples. The new species is widely distributed in the island’s wet-zone lowlands (rainfall > 2,500 mm/yr ), where it occurs in streams, rivers and marshes between the Kelani-River basin draining to the island’s west, and the Gin River basin to the south. It is locally common.

[Ichthyology • 2008] Puntius reval • a new barb (Teleostei: Cyprinidae) from the Maha drainage, Sri Lanka


Puntius reval Meegaskumbura, Anjana Silva, Maduwage & Pethiyagoda, 2008

Abstract
Puntius cumingii, a Sri Lankan endemic, has long been known to be dichromatic. In one colour morph the dorsal, anal and pelvic fins are yellow, while in the other these fins are red. We show that P. cumingii in fact comprises two species. Puntius reval, new species, is distinguished from all other Sri Lankan and south Indian congeners by having the last unbranched dorsal ray serrated; lateral line incomplete, perforating 4-9 scales; scale rows above lateral line arranged in a distinctive pattern; dorsal, anal and pelvic fins red (pale yellow in the Kalu River population); body colour pattern consisting of two black bars, one behind gill pening and one above posterior extremity of anal-fin base; and by lacking barbels. The new species is further distinguished from P. cumingii by having a maximum standard length of 33.6 mm (vs. 41.2 mm); a smaller eye diameter (9.8-10.5, vs. 10.8-12.1 percent of standard length); 11+13 (vs. 11+15) vertebrae; cleithrum with a single spine (vs. smooth); and proximal arm of fifth ceratobranchial with an oval foramen of diameter less than (vs. greater than) basal diameter of teeth. The cytochrome b divergence between P. reval and P. cumingii is 2.0-2.5 %. Puntius reval is described from the Kelani drainage, though it ranges throughout the lowlands northwards to the Maha drainage, whereas P. cumingii is recorded from the more southerly Bentara and Gin drainages.
