Résumé :	Information on carapace morphology of eight Recent ostracod species of the genus Cryptocandona (Candoninae, Candonidae, Cypridoidea), living in surface and groundwater habitats in Europe and Japan, allows to appreciate their pattern of disparity (i.e. morphological diversity). A morphometric analysis of the outlines of adult female valves using Elliptic Fourier Analysis is performed on individuals belonging to geographically separated populations. The data, displayed in a multidimensional morphospace, is analysed using Principal Component Analysis. It is shown that carapace shape patterns of the various species overlap within the Cryptocandona morphospace. The degree of morphological change of the carapaces of Cryptocandona species is evaluated within the context of their geographical and ecological distribution. Comparative data on various Candoninae lineages facilitate discussion on the limits of allocation of fossil candonines to the genus Cryptocandona using only carapace-shape criteria.
