( Figure 5F–J View Figure 5 )


Adult females collected from Jeju Island showed a large size range from 620 through to 709 μm in length (Appendix 1). The dorsal view was noticeably variable in shape, with a width/length ratio ranging from 0.74 through to 0.81 ( Figure 5I, J View Figure 5 ), and with the position of maximum width ranging from a position 38 to 43% of the length from the posterior margin (Appendix 1). This large variation may indicate that cryptic species exist within this widespread parthenogenetic form.

Cypretta seurati   is widespread in circum-tropical regions and warmer areas of temperate zones ( Meisch et al. 2007). It has previously been reported from Korea, including Jeju Island, by Kim and Min (1991a). In our surveys, it was collected from 10 localities (4, 10, 14, 17, 25, 26, 28, 29, 32 and 35) from a wide range of habitats, including marshes, seeps, irrigation ponds, natural pools, and rivers.
