| Max. size: |
9.66 cm SL (male/unsexed) |
| Environment: |
benthopelagic; freshwater |
| Distribution: |
South America: Negro, Amarillo, Catamayo and Macará Rivers, Amazon basin in Ecuador. |
| Diagnosis: |
Dorsal soft rays (total): 12-12; Vertebrae: 38-39. This species differs from all its congeners by having a dark lateral stripe overlaid with a peduncular spot and a reticulated pattern on the sides of the body (vs. peduncular spot and other body pigments not superimposed over a dark lateral stripe). Other diagnostic characters include the following: three simple dorsal–fin rays, the first only visible in cleared and stained material and articulated, along with the second simple ray, with the first dorsal pterygiophores; third simple ray longer, and articulated with second dorsal pterygiophores (vs. only two simple dorsal–fin rays, both articulated with first dorsal ptery¬giophores); and anterior frontals both separated and so the fontanel front parietal continues on the mesethmoid (vs. anterior tips of frontals united and fontanel front parietal no continued on the mesethmoids) (Ref. 93958).
Description: Anal-fin rays iii-iv, 24-28 (Ref. 93958). |
