Postembryonal development of male and abnormal sexual individuals of Alona affinis (Leydig, 1860) (Anomopoda, Chydoridae)

  • Artem Y. Sinev


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 first trunk limb. Males with abnormal morphology in sex-linked characters and ephippial females with a postabdomen similar to that of the adult male are described.
