| Family: |

| Max. size: |
28.56 cm SL (male/unsexed) |
| Environment: |
demersal; marine |
| Distribution: |
South America: Colombia. |
| Diagnosis: |
Dorsal spines (total): 1-1; Dorsal soft rays (total): 7-7; Anal spines: 1-1; Anal soft rays: 5-5. This species is distinguished from all its congeners by having a small group of plates posterior to the urogenital pore (vs. plates absent) and by having a broad, dark brown bar on the first pre-dorsal plate, which occupies the entire plate, reaching the preopercle, and sometimes reaching the second pre-dorsal plate (vs. no bar except in S. evansii); differs further, except from S. euacanthagenys, by having the abdominal surface with scattered, very small plates leaving naked areas (vs. abdomen totally naked or abdominal region partially to completely covered with larger plates); differs S. euacanthagenys and S. fimbriata by having 5 transverse dark brown bars on the dorsal region (vs. 4, and 3 in S. curvispina, 6 in S. caquetae); differs from S. caquetae, S. evansii, S. fimbriata, S. nudiventris, S. tuira by having preanal plates (vs. absent) (Ref. 119417). |
| Biology: |
This species prefer areas of the river with moderate slopes (between 0 and 3%) over substrates consisting of stones (less than 20 cm of diameter) and sand (observations indicate 80% rocks and 20% sand). Specimens captured at altitudes ranging from 197 to 350 m asl; water varies from high turbidity (316 mg/l total solids) to slightly clear, with pH between 6.4 and 8.2, conductivity between 30 and 302 µS/cm, oxygen concentration between 1.6 and 7.64 mg/l, with percent of saturation between 22.5 to 98.8%, water temperature between 22.5 and 28.58°C. This species has been captured with other species of loricariids (Chaetostoma formosae, C. joropo, Farlowella mariaelenae, Lamontichthys llanero), as well as characids (Creagrutus bolivari, Gephyrocharax valencia, Hemibrycon metae, Odontostilbe splendida), a cichlid (Bujurquina mariae), and apteronotids (Apteronotus apurensis, A. galvisi) (Ref. 119417). |
