Etymology: Pterocryptis: Greek, pteron = wing, fin + Greek, kryptos = hidden (Ref. 45335); vorax: Name 'vorax' from the Latin word meaning 'swallowing greedily' or 'devouring', in allusion to the wider gape of this species compared to its congener.

Dorsale zachte stralen (totaal) : 2; Anale zachte stralen: 46 - 57. This species is distinguished from its congeners by the following set of characters: wider gape (posterior margin of rictal lobe extending beyond vertical from posterior margin of orbit); highly contrasting (mottled/reticulated) color pattern on the flanks; dark vertical band at the caudal-fin base; caudal peduncle (8.2-10.4% SL); 48-49 vertebrae; anal-fin rays (46-57); lower jaw with a more gently curved anteroventral margin; and densely distributed dark brown patches on the flanks that coalesce to form a reticulate pattern (Ref. 138537).
Body shape (shape guide): elongated; Cross section: oval.
This species inhabits streams with clear and fast-flowing water, characterized by rocky and
sandy substrate, sometimes with bedrock splitting the stratum and forming small cascades (Ref. 138537).
