Microdevario gatesi (HERRE, 1939)

March 13th, 2012 — 1:26pm

The genus Microdevario was raised by Fang et al. (2009) after phylogenetic analyses revealed that some species formerly included in Microrasbora to be more closely allied with Devario and in need of reclassification. Microdevario is largely separated from Devario and other closely related genera such as Chela and Laubuca by virtue of internal characters but also the following: small adult size; anal and dorsal fins with concave-shaped distal margin; absence of barbels; absence of perforated scales; 9-10 branched anal-fin rays; 7 branched dorsal-fin rays; less abdominal than caudal vertebrae.

Yasuhikotakia splendida (ROBERTS, 1995)

March 13th, 2012 — 1:26pm

This species first appeared in the trade during 2009 with prices initially variable but in the main prohibitively expensive, and it remains expensive when available. We've seen it on sale under various names including 'jaguar loach', 'splendid loach' and 'yellow-tail polka dot loach'.

It appears superficially similar to Y. caudipunctata, Y. longidorsalis and Y. morleti but can be distinguished from all by a combination of characters of which the most immedia…

Dawkinsia rubrotinctus (JERDON, 1849)

March 13th, 2012 — 1:26pm

This species may have appeared in the aquarium trade under the misapplied names Puntius arulius or P. tambraparniei in the past, both of which are also now classified within Dawkinsia. See the relevant profiles for D. arulius and D. tambraparniei for additional information regarding that confusion, since here we concentrate on D. rubrotinctus.

It was initially described by Jerdon in 1849 but placed in synonymy with P. arulius by Day (1878), where it remained for ov…

Mesonoemacheilus herrei NALBANT & BÃNÃRESCU, 1982

March 13th, 2012 — 1:26pm

It’s unclear if this species has ever been exported for the aquarium hobby outside of India but there may be a chance of finding the occasional specimen mixed in with shipments of M. guentheri or M. triangularis. It was earlier considered synonymous and may still be confused with M. guentheri since both species share similar body patterning consisting of rows of yellowish, dark-edged spots.

Mesonoemacheilus triangularis (DAY, 1865)

Zodiac Loach

March 13th, 2012 — 1:26pm

This species is also referred to by the alternative vernacular name ‘Batik loach’ and is the most-commonly traded member of the genus at present. It’s easily-distinguished from congeners by body patterning which comprises a series of pale, oblique saddle-like markings edged in black and running along the dorsal surface, plus a similar set of bars originating from the otherwise plain ventral surface.

Yasuhikotakia caudipunctata (TAKI & DOI, 1995)

Speckle-tailed Loach

March 13th, 2012 — 1:26pm

This specie is relatively rare in the aquarium trade and much sought after by enthusiasts as a result. It looks relatively similar to Y. splendida but can be told apart from it, and indeed all other members of the genus, by the following combination of characters: possession of 8 branched dorsal-fin rays; 32-33 vertebrae; one or two small, brownish, vertically-orientated markings on the dorsal part of the body posterior to the dorsal fi…

Mesonoemacheilus guentheri (DAY, 1867)

March 13th, 2012 — 1:26pm

However, according to the identification key of Rema Devi and Indra (2002), the two can be distinguished by a combination of factors as follows: body spots rounded in shape (vs. ‘Y’ or ‘V’ shaped in M. herrei); caudal peduncle relatively long (vs. relatively short); anal-fin not reaching base of caudal-fin (vs. anal-fin reaching base of caudal-fin); caudal peduncle with a dark band (vs. caudal peduncle with a dark spot); sub…

Misgurnus dabryanus DABRY DE THIERSANT, 1872

Large-scaled Loach

March 13th, 2012 — 1:26pm

It’s actually sold in the aquarium hobby on a regular basis but almost always labelled as or mixed in with Misgurnus anguillicaudatus and is thus poorly documented.

Although quite simi…

Microcobitis misgurnoides (RENDAHL, 1944)

March 13th, 2012 — 1:26pm

This species was initially described as a member of Cobitis and remained as such for over 60 years until being redescribed in the new genus Microcobitis by Bohlen and Harant (2011). It can be separated from Cobitis species by a number of char…

Sinibotia superciliaris (GÜNTHER, 1892)

March 13th, 2012 — 1:26pm

This species is rarely-seen in the trade due to a relative lack of commercial exports from the middle Yangtze basin. It looks very similar to S. pulchra but can be told apart by the fact it lacks irregular, brownish markings and spots on the side of the head (vs. present in S. pulchra), and like most congeners it has a highly flexible, sinuous body which makes it very interesting to observe.
