Etymology: lucifer: The name lucifer refers to the type locality. A name used in apposition.
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. [...] This is a toponym; referring to the Lucifer Mountains, French Guiana, where the holotype was collected. (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 7; Anal spines: 1; Anal soft rays: 5. This species does not possess unique character that distinguishes from all other congeners except its barcode sequence, the most divergent of all Harttiella representatives (JF292286 to JF292296). Differs from other congeners of the crassicauda group except Harttiella intermedia, by having a longer caudal peduncle (mean = 44.26 ± 1.48% of SL vs 36.14 ± 1.66 < mean < 40.36 ± 1.06% of SL); and from other representatives of the longicauda group, by having a greater cleithral width (mean = 101.65 ± 3.28% of HL vs 94.50 ± 4.0 0 < mean < 95.78 ± 4.04% of HL). Can be diagnosed from Harttiella intermedia by having a smaller predorsal length (mean = 35.95 ± 1.19% of SL vs 37.93 ± 1.07% of SL) (Ref. 90209).

Sympatric with Rivulus igneus and Ituglanis sp.
