46. Echiniscus tenuis Marcus, 1928 [T]

E. (E) tenuis ( Marcus, 1928) (du Bois-Reymond Marcus 1944)

Terra typica: Lombok ( Indonesia)

Brazil:

• 22°44′S, 45°35′W; 1,650 m asl: São Paulo State, Campos do Jordão, mosses or aquatic plants. du Bois-Reymond Marcus (1944)

Record numbers: Brazil: 1; total: 1.

Remarks: The only known Echiniscus species with smooth, unsculptured dorsal plates. The presence of cirri A and no other dorsal appendages would place this species in the arctomys group. However, the lack of spine fringe and spurs on leg VI suggest this probably belongs to a different genus and requires further investigation. Currently known only from Indonesia and Brazil.
