The new species Eulimnadia taoluoensis belongs to that group of species of this genus in which the hinge-line of shell is not serrate and the lower distal angle of telson produced in an acute point.The differences between this new species and the closely allied species E. braueriana ( ? ) or E. ovata ( ? ) have been discussed. A table is given to compare the main morphological characters of E. taoluoensis with that of the other nine species (such as Eulimnadia compressa; E. braueriana; E. packarPiana; E. gibba; E. similis; E. kobai; E. ovata; E. michaeli and E.gunturensis) of the genus Eulimnadia which are distributed over Asia.
