Ilyocryptus cf. sarsi from Far East of Russia in Kotov & Štifter 2006, p. 123. Ilyocryptus cf. raridentatus Smirnov in Kotov et al. 2011b, p. 135–136, Fig. 33.

Type locality. "An unnamed swamp near Yarragooly Claypan, via Derby, W.A." ( Smirnov 1989), Australia. Locality in Korea. 6a (see Fig. 1 and Table 1 ).

Notes. Two females from Bak Sil Ji were identical to those earlier found in the Amur basin (see description in Kotov et al. 2011b) and preliminarily identified as Ilyocryptus cf. raridentatus Smirnov, 1989 . The latter species was described from Australia ( Smirnov 1989). It belongs to a circumtropical I. sarsi -group ( Kotov & Štifter 2006) quite common in such Asian countries like Thailand and Malaysia. The Amur basin is the northernmost border of its distribution in Asia ( Kotov et al. 2011b). Some populations from this group were previously found in Japan and few localities in Far East of Russia ( Kotov & Štifter 2006), but their status could be checked only in the scope of a global revision of the sarsi -group. Presence of this taxon in Korea was quite expected after findings in adjacent territories, including more northern ones in Far East of Russia.
