The species in this genus are founsd in South America. ==Etymology== The genus name comes from [Charles Frederick Hartt](/source/Charles_Frederick_Hartt), a geologist, paleontologist and naturalist, who collected the many specimens during the [Thayer Expedition](/source/Thayer_Expedition) to Brazil in the years 1865–1866.{{cite web |url=https://etyfish.org/loricariinae/ |title=Family LORICARIIDAE: Subfamily LORICARIINAE Rafinesque 1815 (Suckermouth Armored Catfishes) |date=30 December 2025 |author=Christopher Scarpf |access-date=7 January 2026 |work=The ETYFish Project Fish Name Etymology Database |publisher=Christopher Scharpf}} ==Taxonomy== As of 1997, ''Harttia'' was considered a [monophyletic](/source/monophyly) taxon. However, ''Harttia'' is in need of revision. For example, the [synonymy](/source/synonym_(taxonomy)) of ''[Cteniloricaria](/source/Cteniloricaria)'' with ''Harttia'' was questionable because it rested solely on the characteristics of ''Harttia fowleri'' without considering the [type species](/source/biological_type) of ''Cteniloricaria''. == Species == ''Harttia'' contains the following recognized species:{{Cof genus|genus=Harttia|access-date=7 January 2026}} {{Linked species list | Harttia absaberi | [Oyakawa](/source/Osvaldo_Takeshi_Oyakawa), [Fichberg](/source/Ilana_Fischberg) & [Langeani](/source/Francisco_Langeani), 2013 | Harttia canastra | [Caldas](/source/La%C3%ADs_Caldas), [Cherobim](/source/Arieli_Matheus_Cherobim) & Langeani, 2022 | Harttia carvalhoi | [P.

The greatest species diversity of ''Harttia'', occurs in the Pre-[Cambrian](/source/Cambrian) Brazilian Shield region.{{cite journal|journal=Copeia|year=2001|issue=1|pages=136–142|title=New Species of ''Harttia'' (Loricariidae, Loricariinae) from the Rio São Francisco Basin|first=Francisco|last=Langeani|author2=Oyakawa, Osvaldo T. |author3=Montoya-Burgos, Juan I. |doi=10.1643/0045-8511(2001)001[0136:NSOHLL]2.0.CO;2|volume=2001|editor1-last=Schaefer|editor1-first=S.
