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 .
