| Family: |

| Max. size: |
3.67 cm SL (male/unsexed) |
| Environment: |
demersal; freshwater |
| Distribution: |
South America: small stream tributary to the Río Puré in Colombia, and two creeks emptying into the Río Amazonas near Iquitos, Peru, in the upper Amazin River basin. |
| Diagnosis: |
Dorsal spines (total): 2-2; Dorsal soft rays (total): 7-8; Anal soft rays: 6-6; Vertebrae: 22-22. Distinguished from all other congeners, except Otocinclus cocama, by having a single,
intensely pigmented, vertical W-shaped caudal fin spot and by having three discrete dark bands on dorsum, between the dorsal-fin base and the caudal fin. Can be separated from Otocinclus cocama by the absence of vertically elongated blotches from the dorsal midline to the ventral border of flanks, and by lacking the posterior extension of black
pigmentation on the base of two central caudal-fin rays. Differs from most Otocinclus
species, except Otocinclus bororo, Otocinclus cocama, Otocinclus mariae, Otocinclus mura, and Otocinclus huaorani, by possessing 20 or more teeth in both the premaxilla and dentary (vs. less that 20 in all other species) (Ref. 75892).
Description: Dorsal fin II,7 or 8; Anal fin i+5; Pectoral fin I,6; Pelvic fin i+5. Vertebrae 22 which excludes those incorporated into Weberian complex (Ref. 75892). |
