| Remarks |
Most specimens were collected using rotenone at shallow rocky reefs in the main channel of the lower Ventuari River. Water parameters taken at one site were as follows: temperature 32°C; pH 6.9; specific conductivity, 12.9 µS/cm; salinity, 0.0 ppt.; dissolved oxygen, 6.6 mg/l or 90.6% saturation. Thirteen other loricariid species have been collected syntopically with this species: Ancistrus macrophthalmus, Baryancistrus beggini, B. demantoides, Hemiancistrus guahiborum, H. subviridis, Hypancistrus contradens, H. lunaorum, Hypostomus squalinus, Leporacanthicus galaxias, Pseudancistrus orinoco, Pseudolithoxus anthrax, P. tigris, and Spatuloricaria sp. Intestinal contents of 3 specimens examined were mostly amorphous organic detritus and inorganic sediment, although gut contents of one individual included two small snail shells (Ref. 87303). |
