Etymology: Psilorhynchus: Greek, psilos = hairless + Greek, rhyngchos = snout (Ref. 45335); robustus: From the Latin adjective robustus, meaning strong or robust, in allusion to the overall robust
appearance of this species. More on authors: Conway & Kottelat.

Morphology | Morphometrics
soft rays: 6. Psilorhynchus robustus is most similar to P. gracilis and P. balitora in overall body shape, meristics and colour pattern. It is distinguished from both species by the presence of a large dark blotch situated posterodorsally to opercle opening, extending along lateral-line scales 3–6 (vs. absence) and in having upper lip separated from the rostral cap by a shallow groove (vs. upper lip separated from rostral cap by a deep groove).
