Echiniscus (Echiniscus) macronyx Richters, 1907 (de Barros 1942 a)
Terra typica: South Georgia (Maritime Antarctic)
Brazil:
• 23 ° 33 ′S, 46 ° 38 ′W; 750 m asl: São Paulo State, São Paulo, mosses. de Barros (1942 a)
Record numbers: Brazil: 1; total: 1.
Remarks: It is not possible to say whether these Brazilian specimens are Testechiniscus macronyx (as re-described, McInnes 1994 b), but description and drawings (de Barros 1942 a) suggest this probably belong to either a different Testechiniscus species or even the Echiniscus arctomys group.
