Etymology: Spectracanthicus: Latin, spectrum = look, apparition + Greek, akantha = thorn (Ref. 45335); immaculatus: Derived from the Latin adjective, immaculatus, meaning unspotted or unstained, in allusion to the coloration pattern of the species, lacking dots or spots.

Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenweichstrahlen (insgesamt) : 8; Afterflossenweichstrahlen: 5; Wirbelzahl: 26. This species is distinguished from all species of Spectracanthicus by its color pattern consisting of a dark gray body, without dots or spots, and by having very slender teeth (vs. with small to mid-sized yellowish dots in S. punctatissimus, S. murinus, and S. tocantinensis; and large white spots in S. zuanoni. This can be further differentiated from S. punctatissimus and S. zuanoni by having pointed snout in dorsal view (vs. snout rounded). Additional characters useful to separate this species from other congeners include the following: nasal quadrangular (vs. nasal L-shaped); posterior margin of pterotic-supracleithrum without contact with posterior margin of orbit (vs. with large contact with orbit in S. murinus and small contact in remaining species); cartilage area of basipterygia short (vs. elongate in remaining species, except in S. murinus); anterior fenestrae of cartilage area of basipterygia large in size (vs. small to median size in remaining species, except in S. tocantinensis) (Ref. 95496).
Body shape (shape guide): fusiform / normal.
