Etymology: Garra: Name based on a vernacular Indian name (Hamilton, 1822:343, Ref. 1813); a fish living in mud (Ref. 128817); robertsi: Named for Dr. Tyson Roberts, a prominent ichthyologist with a long-running focus on Bornean and Southeast Asian fishes.
Eponymy: Dr Tyson Royal Roberts (d: 1940) is an American naturalist and evolutionary biologist who has devoted most of his life to studying biodiversity, particularly that of fishes, throughout the tropics. [...] (Ref. 128868), visit book page.

Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Raggi dorsali molli (totale) : 10; Raggi anali molli: 6. Garra robertsi differs from its only other congener in Borneo, G. borneensis, by the following characters: five transverse scale rows above lateral line (vs. four); when depressed, first dorsal-fin ray extending beyond the posterior-most extent of any other part of the dorsal fin (vs. not extending posteriorly beyond last ray); scales on the breast deeply embedded (vs. exposed); absence (vs. presence) of a stark, contrasting black stripe on lower caudal-fin rays; snout with two nearly continuous patches of tubercles (vs. 3 discrete patches); absence (vs. presence) of a lateral stripe; presence (vs. absence) of broad suborbital bar; a thickened anteromedial fold on the lower lip; and fewer papillae extending onto the callous pad from the posterior flap of the lower lip (Ref. 103293).
Body shape (shape guide): elongated.
