Eigenmann & Allen, 1942"Pterosturisoma microps" is the only
species of themonotypic genus "Pterosturisoma", a genus of the familyLoricariidae ofcatfish (order Siluriformes).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|formattPDF ]This species is only known from the upper Amazon basin. "P. microps" is a
rheophile , which means it likes fast-moving water."P. microps" reaches a length of about 16
centimetre s (6 in) SL.FishBase species|genus=Pterosturisoma|species=microps|year=2007|month=May] "Pterosturisoma" appears morphologically very similar to "Lamontichthys "; however, "Pterosturisoma" has 6pectoral fin rays while "Lamontichthys" has 7. These two genera share features with "Sturisoma " such as similar body depth at thedorsal fin origin, the presence of filamentous extensions oncaudal fin spines, and complete abdominal plate cover that extends to the lower lip margin. The sexes of "P. microps" can be distinguished by the width of a naked trapezoidal area framed by four bony plates in the genital region; this area appeared broader in females, and longer and narrower in males.References
