Etymology: camunani: Name refers to 'camunani', its common name in the Wai-Wai language. The Wai-Wai inhabit the upper rio Trombetas basin, and consider the species of great cultural importance. The common name is also employed by local quilombolas (i.e., inhabitants of settlements founded by escaped slaves of African origin), who capture the fish using as bait the fruit of the camu-camu tree (Myrciaria dubia, Myrtaceae)..

簡短描述
型態特徵 | 形態測量圖
脊椎骨: 40 - 42. Differs from other species of Tometes by its neurocranium with a slight concavity at the level of the frontal bone (vs. concavity absent, dorsal profile of neurocranium straight). It can be further diagnosed among congeners by having five dentary teeth, 81-99 total scales in lateral-line, and 37-42 scales around caudal peduncle. It differs from T. trilobatus by having teeth with central cusp taller and acute (vs. central cusp shorter and with rounded edge); also from T. lebaili by a relatively shorter distance from snout to pectoral-fin origin, 19.1-24.2% SL (vs. 24.5-30.4% SL), shorter head length, 21.4-25.9% SL (vs. 26.6- 29.8% SL), and by possessing a terminal to scarcely subterminal mouth (vs. upturned mouth); from T. makue by having 12-26 prepelvic spines (vs. 0-9), 29-44 total spines (vs. 10-23), and by always possessing a pair of symphyseal dentary teeth, behind the main series (vs. symphyseal dentary teeth sometimes absent) (Ref. 93807).
Gut contents of large specimens measuring 17.5-38.2 cm SL are composed mainly of leaves of Podostemaceae, and fragments of grass and whole seeds of Myrtaceae and Fabaceae. Two smallest specimens examined measuring 9.08 and 13.3 cm SL feed mainly on fragments of Podostemaceae and benthic macroinvertebrates (Leptophlebiidae, Simuliidae and Chironomidae). All dissected specimens contain Oxyuroid nematodes (Rondonia rondoni) in their gastrointestinal tracts (Ref. 93807).
