Etymology: Psilorhynchus: Greek, psilos = hairless + Greek, rhyngchos = snout (Ref. 45335); hamiltoni: Named for Scottish naturalist Francis Hamilton (1762-1829), a pioneer of Indian ichthyology, who spent more than 17 years surveying the freshwater fish fauna of large areas of the Indian subcontinent.
Eponymy: Dr Francis Hamilton né Buchanan (1762–1829) was an ichthyologist and botanist who qualified as a physician at Glasgow (1783) and was to have been a ship’s surgeon, but ill- health that year prevented him taking up the post. [...] (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics
Differs from all other members of the Psilorhynchus balitora species group by the following combination of characters: well-developed lateral stripe; 7-11 round to squarish lateral blotches; 6-7 dorsal saddles; dorsal saddles without contact to lateral blotches; lateral line scales 34-35; principal caudal-fin rays 9+8-9; pectoral-fin rays v-vi.9-11; total vertebrae 36 (18+18); two branchiostegal rays; parietal portion of temporal sensory canal with 2 openings; ventral surface between paired fins with a broad rectangular scaleless patch (Ref. 93866).

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.0 ±0.2 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
