Etymology: Rhynchodoras: Greek, rhingchos = snout + Greek, doras = skin (Ref. 45335); castilloi: Named for Otto E. Castillo G, who collected much of the type material, for his lifelong dedication to the study and stewardship of his country's rich diversity of freshwater fishes.
Eponymy: Otto E Castillo G is a Venezuelan biologist at the Museum of Zoology, National Experimental University of the Western Llanos Ezequiel Zamora, Venezuela. [...] (Ref. 128868), visit book page.

Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 1; Rayons mous dorsaux (Total) : 6; Vertèbres: 41. Differs from Rhynchodoras xingui by having the following characters: all three tympanal scutes weakly developed (vs. second and particularly third well developed, latter with medial carina); midlateral scutes 34-36 (vs. 33 -34); and anterior midlateral scutes relatively shallow,
depth about one-fifth of corresponding body depth, and with dorsal and ventral laminae weakly developed, lacking distinct serrations along posterior margins (vs. depth about one-third to one-quarter of corresponding body depth, and dorsal and ventral laminae well developed with conspicuously serrated posterior margins). Diagnosed from Rhynchodoras woodsi by having a simple swim bladder (vs. each posterior chamber of
gas bladder expanded into elongate horn-like diverticulum), and tubercles punctate and abundant (vs. tubercles elongate, dashlike, and sparse) (Ref. 72419).
Body shape (shape guide): elongated.
Reported to feed on Trichoptera (Ref. 72419).
