Abstract
As in most other Chydoridae, Alona affinis has two juvenile instars in both sexes and development of the male is similar to that of previously studied species. Several interesting traits were found in the development of the f irst trunk limb. Males with abnormal morphology in sex-linked characters an d ephippial females with a postabdomen similar to that of the adult male ar e described.
