Trichorhina amazonica is a species of woodlouse, distributed throughout North-Eastern Brazil.

Its eyes have 10 ommatids and have a dark brown colour.

The anterior margins of pereonite one reach the eyes.

Its pleon outline is continuous with the pereon and the telson is reported to be sub-triangular and slightly concave.

Due to its relatively high amount of ommatids it is theorized to be a more primitive member of the Trichorhina genus.
