  • N. N. Smirnov
Article

Summary

  1. 1.

    The obtained morphological data demonstrate that there are essential differences between Alonopsis elongata and A. ambigua.

     
  2. 2.

    The relocation of A. elongata in the genus Acroperus and of A. ambigua in the genus Alona is based.

Основные результаты

  1. 1.

    Изучено строение Alonopsis elongata и A. ambigua, в результате чего получны новые данные, указывающие на существенные различия между этими видами.

     
  2. 2.

    Обосновывается перенесение A. elongata в род Acroperus и перенесение Alonopsis ambigua в род Alona.

     
  3. 3.
