Taxonomy & naming
Garra banensis was described in 2026 by Yong-Guang Zou, Cai-Xin Liu, Yu-Yang Zeng, Thaung Naing Oo and Xiao-Yong Chen, published in Zoological Research: Diversity and Conservation. It belongs to the genus Garra, part of the subfamily Labeoninae within the family Cyprinidae, and is described from the Ban Chaung drainage, a tributary of the Tanintharyi River in southeastern Myanmar — the first Garra species formally described from that river system. The describing authors distinguish it from other proboscis-bearing congeners in adjacent Southeast Asian drainages using a combination of morphological characters, a result they report as well supported by phylogenetic analysis and genetic distance based on the COI barcoding gene.
The diagnostic combination given for G. banensis includes: a rounded snout bearing a transverse lobe and a nearly quadrate, slightly upturned developed proboscis; a central callous pad (a hardened patch on the disc) that is comparatively long, measuring 26.1-32.7% of head length; a scaled chest; 32-33 lateral-line scales; 4.5 transverse scale rows above and 4.5 below the lateral line; 9 predorsal scales; and 12 circumpeduncular scales. The Catalog of Fishes records the valid combination as Garra banensis Zou, Liu, Zeng, Thaung & Chen, 2026, with no parentheses around the authority, indicating the species was described in the genus it still carries. The specific epithet banensis is a toponym referring to Ban Chaung, the type stream.
Morphology
No absolute length measurements for Garra banensis were accessible for this article; the primary description's full morphometric tables were not reached from the sources used here. What is documented is the diagnostic combination used to separate it from related proboscis-bearing Garra in nearby drainages: a rounded snout carrying a transverse lobe and a nearly quadrate, slightly upturned proboscis (the fleshy projection typical of many Garra species, used together with the ventral oral disc for gripping rock in fast water); a central callous pad on the disc that is proportionally long, at 26.1-32.7% of head length; a fully scaled chest (in contrast to congeners with a naked or partly scaled chest); 32-33 scales along the lateral line; 4.5 transverse scale rows both above and below the lateral line; 9 predorsal scales; and 12 scales around the caudal peduncle.
Colour pattern, fin-ray counts and further body proportions beyond this diagnostic set were not accessible for this article.
Habitat
Garra banensis is known from Ban Chaung, in the upper Tanintharyi River drainage near Myitta village, Dawei, Tanintharyi Region, southern Myanmar, at approximately 14.16°N, 98.52°E. The Catalog of Fishes gives its distribution as the Tanintharyi River drainage of Tanintharyi Region in southern Myanmar, and it is reported as the first species of Garra formally described from this drainage. Specific water chemistry, current speed and substrate at the type locality were not accessible for this article, though species carrying a developed proboscis and oral disc, as this one does, are generally associated with clear, fast-flowing streams over rock — a genus-level inference, not a documented habitat description for this species specifically.
Feeding
No dietary study specific to Garra banensis has been published. The genus Garra as a whole is characterized by a ventral, disc-like mouth used to graze algae and biofilm (aufwuchs) from rock surfaces in flowing water, often supplemented with small invertebrates, and the proboscis and callous pad diagnosing this species are part of that same feeding apparatus — a genus-level inference, not a finding reported for G. banensis specifically.
Mating
No courtship behaviour has been documented for Garra banensis, and no sexual dimorphism beyond the standard diagnostic characters is reported in the sources accessible for this article.
Breeding
Garra banensis has not been spawned or observed breeding in the wild, as far as published sources show. Cyprinids in general, including labeonine genera such as Garra, are typically egg-scattering broadcast spawners with no parental care — a family-level generalization, not a confirmed account of this species' reproductive biology.
In the aquarium
Garra banensis is not established in the aquarium hobby and has no husbandry record; it was described only in 2026 from a single Myanmar drainage. The genus Garra more broadly does include species kept in the aquarium trade as algae-eaters — Garra rufa (the "doctor fish" used in fish-spa exfoliation treatments) and Garra flavatra (the "panda garra") among the better-known examples — but this is a genus-level observation, not evidence that G. banensis itself is collected or traded. Like most Garra it would be expected to need strong current and high oxygenation if ever kept, based on its documented affinity for fast-flowing water.
Conservation
Garra banensis has not been evaluated by the IUCN Red List, having been described only in 2026. Its known distribution is limited to Ban Chaung in the upper Tanintharyi drainage of southern Myanmar, and no population, trend or threat data specific to the species were accessible for this article.
