duri punggung lunak (Keseluruhan (total)) : 7 - 9; Sirip dubur lunak: 14 - 16; vertebrata, bertulang belakang: 33 - 34. Atlantirivulus guanabarensis can be diagnosed from all species of the genus Atlantirivulus by the following combination of characters: lateral line divided into two sections (vs. single); lateral line with one neuromast by scale (vs. lateral line often interrupted by scales without neuromasts); 22 - 26 neuromasts in the section of infraorbital series around orbit (vs. usually 17 - 22, sometimes 23 or 24); distal margin of the anal fin and ventral margin of the caudal fin with a narrow, well-defined dark reddish grey stripe in males (vs. never a similar color pattern), melanophore patch on the postorbital region extending ventrally to the pre-opercular series of neuromasts (vs. not reaching pre-opercular series of neuromasts); snout blunt (vs. slightly pointed); ventral portion of head and venter white (vs. orangish yellow); flank without triangular light blue spots in males (vs. present); and base of the dorsal and anal fins without grey reticulum in males (vs. present) (Ref. 102354).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00661 (0.00311 - 0.01404), b=3.09 (2.91 - 3.27), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

Daya lenting (Ref. 120179): Tinggi, Waktu penggandaan populasi minimum kurang dari 15 bulan (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
