Etymology: intermedia: From the Latin intermedius meaning intermediary, in reference to the contradiction between morphometry and genetics.
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.

Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenweichstrahlen (insgesamt) : 7; Afterflossenstacheln: 1; Afterflossenweichstrahlen: 5. Distinguished from other congeners by its stocky body shape reminiscent of the crassicauda group, and by its mitochondrial barcode signature typical for the longicauda group (JF292281, JF292284, JF292285). Differs from Harttiella parva plus representatives of the longicauda group except Harttiella pilosa by having a deeper body at dorsal-fin origin (mean = 12.69 ± 0.54% of SL vs 9.86 ± 0.79 < mean < 10.66 ± 0.87% of SL); and from Harttiella janmoli by having a shallower body at dorsal-fin origin (mean = 12.69 ± 0.54% of SL vs 14.80 ± 1.14% of SL). Can be separated from Harttiella pilosa by having a longer head (mean = 26.18 ± 1.12% of SL vs 23.74 ± 1.35% of SL), and from Harttiella crassicauda by having a longer caudal peduncle (mean = 42.35 ± 1.44% of SL vs 36.14 ± 1.66% of SL) (Ref. 90209).
