Trichorhina boliviana is a species of woodlouse found throughout Bolivia. It was first described as Phalloniscus bolivianus.[1]
It is 4.5mm long. A slight purplish-brown band runs the length of the pereon and pleon, increasing in width towards the end. The band has a small circular depigmented spot on each segment, which indicates the presence of a muscle fiber. It has a domed tergite. The pleon is recessed at the pereon and ends in a sharp point. Its telson is triangular with rounded edges and covered in large scales. The entire body is surrounded by a belt of relatively large scales.[2]
