Etymology: parva: From the Latin 'parvus' , meaning small, in reference to the size of the species.
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.

Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale zachte stralen (totaal) : 7; Anale stekels: 1; Anale zachte stralen: 5. Distinguished from all congeners by its small size with sexual dimorphism expressed around 25 mm SL (vs around 30 mm SL in congeneric species), by the distinct banded color pattern of the caudal fin (vs blotched or indistinct banded pattern in congeneric species), and by its specific barcode sequences (JF292274, JF292275, JF292276). This species does not exhibit unique morphometric tendencies distinguishing it from all other congeneric species. Differs from other congeners except Harttiella intermedia by a caudal peduncle: shorter compared to the species belonging to the longicauda group [mean = 40.36 ± 1.06% of SL vs 43.61 ± 1.79 < mean < 44 .26 ± 1.48% of SL; (HSD, p-values < 0.0002)], and longer compared to the other species of the crassicauda group [mean = 40.36 ± 1.06% of SL vs 36.14 ± 1.66 < mean < 38 .32 ± 1.54% of SL; (HSD, p-values < 0.0281)]. Can be diagnosed from Harttiella intermedia by a smaller body depth at dorsal-fin origin [mean = 10.34 ± 0.83% of SL vs 12.69 ± 0.54; (HSD, p-value = 0.0041)] (Ref. 90209).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00181 - 0.00834), b=3.12 (2.94 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  2.9   ±0.2 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
