Etymology: Cambeva: Probably derived from the Tupi-Guarani, is a popular name for trichomycterid fishes in southern and south-eastern Brazil (Ref. 119381); galactica: Name 'galactica' from the Ancient Greek word 'galaktikós', meaning 'milky', in allusion to the rows of yellowish white diffuse vermiculate marks present in the flank of the new species, reminiscent of the Milky Way.

Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 2 - 3; Raggi dorsali molli (totale) : 6 - 7; Spine anali: 2; Raggi anali molli: 5; Vertebre: 39 - 40. This species is distinguished from its congeners by the following set of characters: unique colour pattern in adult specimens consisting of flank and dorsum with longitudinal rows of interconnected yellowish white vermiculate diffuse marks; distinctive projection on the anterior portion of the medial margin of the sesamoid supraorbital present, connected by thin ligamentous tissue to a dorsal projection on the articulatory shell of the autopalatine for the lateral ethmoid; pectoral-fin rays 6; well-developed pelvic fins; interopercular odontodes 29-32; jaw teeth 41-43 on the premaxilla; 39-46 on the dentary; 14 or 15 rib; opercular odontodes; minute pectoral-fin filament, its length less than 5% of the pectoral-fin length; procurrent caudal-fin rays 18 or 19 dorsal and 12 or 13 ventral; vertebrae 39 or 40 (Ref. 137708).
Body shape (shape guide): elongated; Cross section: oval.
