Pseudarmadillo tuberculatus is an extinct species of isopod in the family Delatorreiidae known from a series of possibly Miocene[1] fossils found on Hispaniola.

The type specimens were collected from an undetermined amber mine, in fossil bearing rocks of the Cordillera Septentrional mountains, northern Dominican Republic.

The amber was produced by resin from the extinct tree Hymenaea protera, which formerly grew on Hispaniola, across northern South America and up to southern Mexico.

[2][4] The Pseudarmadillo tuberculatus specimens are moderately well preserved, though since isopods lack the wax coatings found in insects, they show deterioration and distortion from the resin after entombment.

The cephalon has notably enlarged antennal lobes that served to shelter the antenna when an individual curled into a defensive ball.
