A 123.2 mm TL female of Iksookimia longicorpa with a laminar circularis at the base of its pectoral fin was collected in the Hoeya River, Korea, on May 5, 2008. The specimen had full-grown ovaries like those of normal females. Its pectoral fins were larger than those of normal females, but was smaller than those of males. The laminar circularis of the pectoral fin base was more similar to normal males in its shape but was less developed. The ovaries in the individual had about 3,148 mature eggs, with egg sizes approximately $1.26{\pm}0.11mm$.
