Genus Parakermania Vandel, 1973

Type species: Parakermania minima Vandel, 1973

Diagnosis. Parakermania able to roll up into perfect ball, dorsum with distinct tubercles; head with short and stout antenna, cephalon with frontal shield slightly protruding over vertex; epimera of pereonites and pleonites curve outwards, and pereonites 2−7 with triangular epimera, pereonites 1 and 2 with small lobe and large tooth on ventral side, respectively; telson with quadrangular distal part, uropodal protopodite nearly trapezoidal, minute exopodites inserted dorsally on protopodite (Kwon & Taiti 1993).

Remarks. The relationships among the genus Parakermania and the other genera within the family Armadillidae are unknown. In morphology, the genus is close to Tuberillo Schultz, 1982 (Taiti et al. 1992). But it can be distinguished by the frontal shield protruding less over the vertex, the pereonites 2−7 with triangular epimera instead of quadrangular epimera, and the pereonite 1 with a small ventral lobe instead of a schisma (Kwon & Taiti 1993).
