A new species of Devario has been described in a recent issue of the journal Zootaxa.
Kevin Conway, Richard Mayden and Kevin Tang name the new species from Bangladesh Devario anomalus.
Devario anomalus is distinguished from congeners by its unique colour pattern, consisting of 5"8 dark, irregular, vertical bars restricted to the front half of the body and widely separate from a short, broad P-stripe, originating level with or behind the origin of the anal fin.
It is further distinguished from congeners reported from Bangladesh the presence of maxillary barbels, an ascending process on the first infraorbital, and a lower number of lateral-line scales, branched dorsal-fin rays, branched anal-fin rays, and circumpeduncular scale rows.
The species is named after the irregular vertical bars on the front half of the body (Greek anomalos=irregular).
Conway told Practical Fishkeeping that he did not think the species had been in the aquarium trade.
