"Pseudohemiodon" is a genus of catfishes (order Siluriformes) of the family Loricariidae. It includes seven species, "P. amazonus", "P. apithanos", "P. devincenzii", "P. laminus", "P. laticeps", "P. platycephalus" and "P. thorectes".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]

Distribution

"Pseudohemiodon" is distributed in the Amazon, Orinoco, and Paraná River basins.cite journal|url=http://www.mapress.com/zootaxa/2007f/zt01462p040.pdf|title=The genera of the Neotropical armored catfish subfamily Loricariinae (Siluriformes: Loricariidae): a practical key and synopsis|first=Raphael|last=Covain|coauthors=Fisch-Muller, Sonia|journal=Zootaxa|volume=1462|pages=1–40|year=2007|format=PDF] "P. amazonus" occurs in the lower Amazon River basin in Brazil. "P. apithanos" originates from the San Miquel River basin of the western Amazon River drainage in Ecuador. "P. devincenzii" is distributed in the Uruguay River basin in Uruguay. "P. laminus" inhabits the upper Amazon River basin of Peru. "P. platycephalus" is known from the Paraguay River basin, Brazil. "P. laticeps" is from the Uruguay, Paraná, and Paraguay River basins. "P. thorectes" lives in the Mamoré River basin of Bolivia.

Description

The body of "Pseudohemiodon" species is very flat and the pelvic fins are used mainly for locomotion on sand. Sexual dimorphism is unknown.

Ecology

like other members of the "Pseudohemiodon" group, "Pseudohemiodon" occurs primarily over sandy substrates. Also like the other genera in the "Pseudohemiodon" group, species of this genus are abdomino-lip brooders. The very large eggs are incubated by the male.
