Puntius terio (HAMILTON, 1822)

Onespot Barb

March 13th, 2012 — 1:24pm

This species is uncommon in the aquarium trade which is a little surprising given its huge natural range. Different populations can vary in colour pattern to an extent though all share the defining aspects given by Hamilton, comprising a diffuse yellow-golden marking on the operculum plus a dark spot on the caudal peduncle. The latter is usually surrounded by a variably-sized golden-yellow margin, and the dorsal-fin often contains irregular dark spots and streaks, these sometimes forming a longitudinal band.

Desmopuntius foerschi (KOTTELAT, 1982)

March 13th, 2012 — 1:24pm

D. foerschi is sometimes traded as ‘boomerang barb’ or ‘Foersch’s fire barb’ and is included in a group of closely-related, similar-looking fishes which were moved into the new genus Desmopuntius by Kottelat (2013).

It can be told apart from other vertically-striped congeners by possession of additional dark blotches between the second, third and fourth vertical bars and a further marking at the posterior base o…

Pethia erythromycter KULLANDER, 2008

Lipstick Barb

March 13th, 2012 — 1:24pm

This species first appeared in the aquarium hobby in 2006 and is sometimes traded under the name ‘Tulip barb’. It was officially described by Kullander in early 2008 in a paper describing five new Puntius species from Kachin, all of which are superficially similar in possession of a dark band or blotch on the caudal peduncle.

P. erythromycter can be distinguished b…

Pethia stoliczkana (DAY, 1871)

March 13th, 2012 — 1:24pm

This species is confused with P. ticto in much of the available literature and is sometimes listed as a synonym of it. Although some populations of the two species possess a similar colour pattern (there are reports of a P. ticto variant from the south of West Bengal state in India with a red, black-flecked dorsal-fin, for example) they do not occur in the same waters in nature and can be distinguished by examining the lateral line. This is complete in…

Dawkinsia assimilis (JERDON, 1849)

Mascara Barb

March 13th, 2012 — 1:24pm

D. assimilis has been misidentified as Puntius mahecola (Valenciennes 1844) in the past but the identity of both species was resolved by Pethioyagoda and Kottelat (2005 a, 2005b). They inspected the syntypes of P. mahecola and concluded that though valid it isn’t closely related to any Dawkinsia (then the Puntius filamentosus group) but is rather a smaller, silvery fish with a single dark blotch on the caudal peduncle, located entirely posterior to the anal-fin. It’s wi….

Pethia padamya (KULLANDER & BRITZ, 2008)

Odessa Barb

March 13th, 2012 — 1:24pm

This species has been in the aquarium trade since the early 1970s but its precise origin was a mystery until 2003. It first appeared in Ukraine, the common name ‘Odessa’ being derived from the port city of that name, and when it arrived in western Europe was widely considered a hybrid of similar-looking congeners such as P. conchonius, P. ticto and P. cumingii. It was also hypothesised as a subspecies of P. ticto or P. conchonius, and some suggested the fish to be artificially dyed.

Dawkinsia tambraparniei (SILAS, 1954)

'Arulius' Barb

March 13th, 2012 — 1:24pm

D. exclamatio should also have a sub-terminal mouth and lack dorsal-fin filaments but some specimens possess a terminal mouth and/or possess dorsal filaments, and one specimen also had black caudal-fin tips as typically seen in D. filamentosa, whereas the description states that the fin tips are only dusky and lack distinctive markings.

Sawbwa resplendens ANNANDALE, 1918

March 13th, 2012 — 1:23pm

S. resplendens is traded under several names including ‘Asian rummynose’, ‘rummynose rasbora’ and ‘naked microrasbora’. It can be immediately distinguished from all other Asian cyprinids by the distinctive colour pattern.

The genus Sawbwa is currently monotypic and endemic to the isolated lake basin of Inlé in Shan State, eastern Myanmar.

Desmopuntius rhomboocellatus (KOUMANS, 1940)

Snakeskin Barb

March 13th, 2012 — 1:23pm

Endemic to southern Kalimantan, the Indonesian portion of Borneo where it’s been recorded from several river systems including the Kapuas, Kepayang, Barito and Kahajan. Type locality is given as ‘Canal along the highway from Oelin to Bandjermasin, about 15 kilometers from Bandjermasin, Borneo.’

Often referred to as the ‘rhomb’ or ‘rhombo’ barb and included in a group of closely-related, similar-looking congeners which also includes…

Pethia phutunio (HAMILTON, 1822)

Dwarf Barb

March 13th, 2012 — 1:23pm

In P. phutonio the flank markings comprise two black, vertically-orientated blotches, one posterior to the operculum and the other on the caudal peduncle, and within the P. conchonius group this patterning is shared with P. bandula, P. cumingii, P. didi, P. meingangbii, P. padamya, and P. tiantian.

It can be told apart from these by the following combination of characters: smaller adult size of 25 – 30 mm vs. at least 35 – 40 mm; minute maxillary barbels; incomplete lateral line with ab…
