Etymology: janmoli: Named for the Dutch ecologist Jan H. Mol for his strong personal investment in the knowledge and protection of Harttiella, especially in Suriname where he recovered the highly vulnerable Harttiella crassicauda.
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. [...] Dr Jan H A Mol is a Dutch ecologist based at Anton de Kom University of Suriname where he is Professor of Aquatic Ecology. [...] (Ref. 128868), visit book page.

Short description
Claves de identificación | Morfología | Morfometría
Radios blandos dorsales (total) : 7; Espinas anales: 1; Radios blandos anales: 5. Distinguished from all other species of Harttiella by its dark brown coloration with a large
transverse postdorsal saddle corresponding to the position in congeners of the third and fourth bands posterior to dorsal- fin origin (vs. brownish normally with five postdorsal bands). Differs further from other species by having the following morphometric characters: longer pectoral spines [mean = 27.14 ± 1.54% of SL vs 21.14 ± 0.98 < mean < 24.06 ± 0.84% of SL); longer pelvic spines [mean = 24.67 ± 1.46% of SL vs 19.36 ± 1.17 < mean < 22.86 ± 1.64% of SL); a greater anus to pelvic-fin origin length [mean = 12.88 ± 0.96% of SL vs 9.29 ± 1.42 < mean < 11.31 ± 1.01% of SL); anus to pectoral-fin origin length [mean = 34.24 ± 1.67% of SL vs 28.38 ± 2.75 < mean < 31.85 ± 2.26% of SL); and anus to tip of snout length (mean = 49.81 ± 1.63% of SL vs 43.32 ± 1.42 < mean < 48.09 ± 1.93% of SL; a wider body at dorsal-fin origin [mean = 23.46 ± 1.18% of SL vs 17.28 ± 1.11 < mean < 20.06 ± 1.61% of SL); and a deeper body at dorsal-fin origin [mean = 14.80 ± 1.14% of SL vs 9.86 ± 0.79 < mean < 11.41 ± 1.41% of SL) (Ref. 90209).
