"Ernstichthys" is a genus of catfishes (order Siluriformes) of the family Aspredinidae. It includes three species, "E. anduzei", "E. intonsus", and "E. megistus".cite journal|url=http://silurus.acnatsci.org/ACSI/library/biblios/2007_Ferraris_Catfish_Checklist.pdf|title=Checklist of catfishes, recent and fossil (Osteichthyes: Siluriformes), and catalogue of siluriform primary types|first=Carl J., Jr.|last=Ferraris|journal=Zootaxa|volume=1418|pages=1–628|year=2007|format=PDF]

This genus occurs in the Amazon and Orinoco basins.cite paper|url=http://www.cumv.cornell.edu/pdf/Friel_Ph.D._Thesis_1994.pdf|title=A Phylogenetic Study of the Neotropical Banjo Catfishes (Teleostei: Siluriformes: Aspredinidae)|author=Friel, John Patrick|publisher=Duke University, Durham, NC|date=1994-12-13|accessdate=2007-08-07|format=PDF] "E. anduzei" occurs in the Orinoco River basin of Venezuela. "E. intonsus" is known from the Napo River basin of Ecuador. "E. megistus" inhabits the Bobonaza and Marañon River basins of Ecuador and Peru.

"Ernstichthys" species are small to medium sized, armored aspredinids. "E. anduzei" grows to 3.5 centimetres (1.4 in) SL.FishBase species|genus=Ernstichthys|species=anduzei|year=2007|month=Aug] "E. intonsus" grows to 4.9 cm (1.9 in) SL.FishBase species|genus=Ernstichthys|species=intonsus|year=2007|month=Aug] "E. megistus" grows to about 6.7 cm (2.6 in) SL.FishBase species|genus=Ernstichthys|species=megistus|year=2007|month=Aug] Members of this genus are distinguished from all other aspredinids by having two sets of paired pre-anal-fin plates and a strongly recurved pectoral spine that is much longer than first branched pectoral-fin ray.
