S7. Character matrix of for phylogenetic analysis of Plesiosminthus, Megasminthus and Sicista used in the phylogenetic analysis of Kimura (in press b). Missing or unknown data are coded as ‘?’. ‘A’, ‘B’, ‘C’, ‘D’, ‘E’, and ‘F’ are designated for polymorphic character states, ‘0/1’, ‘0/2’, ‘0/3’, ‘1/2’, ‘2/3’, and ‘1/3’, respecrively. Characters are listed in Supplementary Table 1.
