Etymology: Horaglanis: Taken from mister S.L.Hora, director of Zoological Survey of India + Latin, glanis = a cat fish (Ref. 45335)populi: Name 'populi' from the Latin words 'populus', meaning 'people', in honor of the invaluable contributions made by interested members of the public in the southern Indian state of Kerala in documenting the biodiversity of subterranean and groundwater systems, including this novel species.
Eponymy: Dr Sunder Lal Hora (1896–1955) was a distinguished Indian ichthyologist and biologist who held a doctorate in science from both the Punjab University (1922) and Edinburgh University (1928), having studied for his master’s at the Government College, [...] (Ref. 128868), visit book page.

Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

This species is distinguished from its congeners by the following set of characters: body elongated, round in cross section anteriorly, laterally compressed posteriorly, dorsal profile slightly convex to start of dorsal fin, straight more posteriorly; ventral profile convex in head region, then straight posteriorly; head large, 15.7-20.4% standard length, with dorsally and laterally bulging adductor muscles; snout truncated; mouth wide, terminal; absence of eye; 4 pairs of barbels; 2 mandibular, 1 maxillary and 1 nasal barbel pair; nasal and inner mandibular barbels shorter than maxillary and outer mandibular barbels; maxillary and outer mandibular barbels reaching posterior border of pectoral fins when folded back; large gill opening, extending to slightly above pectoral-fin base; gill membranes united with isthmus; absence of scales; caudal peduncle laterally compressed, 9.3-16.9% of standard length; dorsal fin long, with 22-23 soft rays (xiii-xiv unbranched/8-9 branched), originating in advance of pelvic fin origin; anal fin long, with xiii-xvii unbranched rays, starting opposite dorsal fin ray number 9, ending opposite base of last dorsal fin ray; pectoral fin vestigial, consisting only of modified pectoral fin spine covered by thickened skin; pelvic fin short, wide, with rounded margin, with ii-iv unbranched and 2-4 branched rays; caudal fin with rounded posterior margin, with 8-9 branched and 2-4 dorsal unbranched and 2-4 ventral unbranched rays; head skeleton well ossified; neurocranium with a single large cranial fontanelle, no epiphyseal bridge connecting frontals in dorsal midline; lateral neurocranium wall with large trigeminofacial foramen; supraoccipital with long, narrow and pointed crest; opercle small and subtriangular; and jaws massive, dentary and premaxilla studded with numerous rows of closely set, recurved villiform teeth (Ref. 137782).
Body shape (shape guide): elongated; Cross section: circular.
