?Annamia thuathienensis NGUYEN, 2005

March 13th, 2012 — 1:25pm

Annamia spp. may be confused with related genera such as those of the genus Balitoropsis. They can be identified by their more depressed body shape, elongate lower caudal-fin lobe, and the presence of a single unbranched ray in the pectoral and pelvic fins. At least one undescribed member of the genus is thought to exist.

Lepidocephalichthys hasselti (VALENCIENNES, 1846)

March 13th, 2012 — 1:25pm

At one locality close to Ban Na Hwai, Chiang Mai Province, Thailand L. hasselti was collected from a shallow (<0.5 m) pool in a swampy zone between forest and rice fields. The substrate was of mud, there was no aquatic vegetation and it was being used as drinking water by local animals, with the only effluent connected to a 'small creek'. Other species found there were Physoschistura pseudobrunneana, Rasbora hobelmani and Systomus cf. orphoides.

Botia rostrata GÜNTHER, 1868

March 13th, 2012 — 1:25pm

Within the nominal species grouping suggested by Grant (2007) almost all B. rostrata sold in the hobby are B. sp. 'upper Brahmaputra' with B. rostrata sensu stricto rarely, if ever, available. Trade names include 'Gangetic loach', 'twin-banded loach' and 'ladder loach'. The defining characters of the group are "Pattern consisiting of 8-10 black to dark brown body bars that exhibit pale and numerous spots in juveniles, and in adults the bars can anast…

Aborichthys sp. 'AR02'

March 13th, 2012 — 1:25pm

This fish occasionally turns up as a contaminant in shipments of A. sp. 'AR01'. The latter is usually traded as A. elongatus but that species appears endemic to higher altitude waters of the Brahmaputra drainage in Darjeeling District which borders Jalpaiguri to the north east. These flow down from the Sivalik Hills whereas the Raidak I originates in Bhutan. Only three species of Aborichthys have been officially described to date meaning this is likely to represent an undescribed speci…

Botia histrionica BLYTH, 1860

March 13th, 2012 — 1:25pm

Adult patterning of the different geographical forms can vary considerably though young specimens all possess 5 solid dark bars on each flank and are often confused with those species exhibiting a similar juvenile pattern, particularly B. kubotai. However the horizontal dark bars on the flanks in B. kubotai typically split at quite a young age and/or develop horizontally-orientated ‘peaks’ whereas those in B. histrionica remain solid for longer and the central bar usually has a pale spot at the top so forms a ‘y’ shape.

Botia kubotai KOTTELAT, 2004

Polka-Dot Loach

March 13th, 2012 — 1:25pm

Appears to be endemic to headwaters of the Salween River basin around the border between Myanmar and Thailand. The type specimens were collected from the Megathat Chaung (Megathat stream) in the upper Ataran (known as the Kasat in Thai) River basin, Kayin/Karen State, Myanmar and another population was later discovered in the Hanthayaw River (Suriya in Thai), Tak Province, Thailand.

Botia udomritthiruji NG, 2007

Emperor Botia

March 13th, 2012 — 1:25pm

Known only from the Tanintharyi River drainage in Tanintharyi (previously Tenasserim) Division, southern Myanmar. Tanintharyi lies on the Kra Isthmus and the river bisects the central zone north-to-south before emptying into the Andaman Sea at Mergui/Myeik.

This area is not easy to access for fish collectors due to occasional conflict between the Myanma…

Acanthopsoides sp. 'A01'

March 13th, 2012 — 1:25pm

Acanthopsoides spp. are most closely related to the horse-faced loaches of the genus Acantopsis with which they often co-occur in nature, and thus commonly referred to as 'dwarf horse-face loaches'.

Acanthopsoides sp. 'A02'

March 13th, 2012 — 1:25pm

Acanthopsoides spp. are most closely related to the horse-faced loaches of the genus Acantopsis with which they often co-occur in nature, and thus commonly referred to as 'dwarf horse-face loaches'. The genus currently comprises five species of which four were described by Siebert (1991);…

Hemimyzon formosanus (BOULENGER, 1894)

March 13th, 2012 — 1:25pm

Current knowledge suggests that H. formosanus is the most widely-distributed and following Chen and Fang (2009) it can be distinguished by the following suite of characters: 3+7 dorsal-fin rays; 10-12 pectoral-fin rays (modally 11) +9-11 (modally 10)…
