Diagnostic Description

provided by Fishbase
Can be distinguished from all congeners by its hispid appearance (vs. smooth to velvety in congeneric species) and its specific barcode sequences (JF292271, JF292272, JF292273). Differs from species belonging to the crassicauda group by a shorter head [mean = 23.74 ± 1.35% of SL vs 25.54 ± 1.41 < mean < 26.18 ± 1.34% of SL; (HSD, p-values < 0.0033)], and from other species of the longicauda group by a deeper body at dorsal-fin origin [mean = 11.92 ± 0.97% of SL vs 9.86 ± 0.79 < mean < 10.66 ± 0.87% of SL; (HSD, p-values < 0.0069)] (Ref. 90209).

This species was encountered immediately upstream of a 30 m high waterfall and was collected downstream of the waterfall. The area of the river where this species was found was 10 m wide with shallow clear water and a bottom substrate consisting of gravel, pebbles, boulders, bed rock and sand mainly constituted of iron hydroxide (Ref. 90209).

Harttiella pilosa

provided by wikipedia EN

Harttiella pilosa is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Orapu River basin in the Tortue Mountains of French Guiana. The type locality of the species is the area directly upstream and downstream of a 30 m (98 ft) high waterfall. This environment is a 10 m (33 ft) wide river channel with shallow, clear water and a substrate composed of gravel, pebbles, boulders, bedrock, and iron-rich sand. The species reaches 4 cm (1.6 inches) in standard length.[1] It was described in 2012 as part of a taxonomic review of members of the loricariid tribe Harttiini native to the Guianas.[2]
