"Pterosturisoma microps" is the only species of the monotypic genus "Pterosturisoma", a genus of the family Loricariidae of catfish (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 centimetres (6 in) SL.FishBase species|genus=Pterosturisoma|species=microps|year=2007|month=May] "Pterosturisoma" appears morphologically very similar to "Lamontichthys"; however, "Pterosturisoma" has 6 pectoral fin rays while "Lamontichthys" has 7. These two genera share features with "Sturisoma" such as similar body depth at the dorsal fin origin, the presence of filamentous extensions on caudal 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.
