Etymology: Aspidoras: Greek, aspis, -idos = shield + Greek, dora = skin (Ref. 45335); psammatides: Named after "Psammatos psammatides", the sand sorcerer, a characer of the J.R.R. Tolkien's book "Roverandom", from the Greek psammos, meaning sand, and ides, meaning son of. In allusion to the sand-dwelling behavior of the species.

Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 1; Raios dorsais moles (total) : 8. This species is distinguished by the following characters: with extremely narrow frontal bone, its width conspicuously smaller than half of its entire length; anterior portion of infraorbital 1 with strongly reduced laminar expansion, not reaching or at same level as posterior margin of nasal capsule; presence of dorsal-fin spinelet (Ref. 129024).
Body shape (shape guide): elongated; Cross section: oval.
Facultative air-breathing (Ref. 126274); Inhabits highly transparent brownish water (tea colored), up to one meter depth, with moderate current, and substrate composed of sand, gravel and larger rocks (typical at the rio Capivara, a tributary to the rio Paraguaçu basin). Found in syntopy with Characidium clistenesi, and both species were observed to forage next to each other, with no conspicuous interactions (Ref. 129024).
