Etymology: fluminensis: The specificn name 'fluminensis' is from the Latin flumen meaning river, in reference to the ecology of Harttia that represents a group of rheophilic fish from the main channel of rivers.
Eponymy: Charles Frederick Hartt (1840–1878) was a Canadian geologist, palaeontologist and naturalist, who was a member of the Thayer Expedition (1865–1866) to Brazil, a country in which he was a specialist. [...] (Ref. 128868), visit book page.

Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Raggi dorsali molli (totale) : 7; Spine anali: 1; Raggi anali molli: 5. Distinguished from all other species of the genus Harttia except Harttia tuna and Harttia trombetensis by having an incomplete abdominal cover, restricted to preanal and abdominal lateral plates with a row of platelets joining these two series of plates (vs. absence of row of platelets making junction between preanal and lateral abdominal plates), and by its specific barcode sequence (JF292263). Differs from Harttia tuna by having a deeper head (37.31-43.30, mean 38.94 ± 1.42% of HL, vs 31.96-38.77, mean 36.52 ± 1.80% of HL), and from Harttia trombetensis by its color pattern of caudal fin (a large dark band at base of caudal fin vs. a dark rounded blotch). Can be further diagnosed from all other congeners by having a greater minimum caudal peduncle depth (mean = 1.60 ± 0.11% of SL vs. 1.35 ± 0.13 < mean < 1.43 ±0.11% of SL); and a greater interorbital width (mean = 24.25 ±1.02% of HL vs. 22.04 ± 1.27 < mean < 23.12 ± 1.11% of HL) (Ref. 90209).
Body shape (shape guide): elongated.
Frequents main channel over rocky and sandy bottom in fast flowing waters (Ref. 90209).
