oa Journal of the Entomological Society of Southern Africa - Meiosis in a number of South African Euryphyminae grasshoppers (Orthoptera: Acrididae)

Volume 54, Issue 2
  • ISSN : 0013-8789



Meiosis in five species of Euryphyminae, Amblyphymus adspersus, Am. roseus, Aneuryphymus erythropus, Calliptamicus semiroseus and Euryphymus tuberculatus is descriptionbed. The karyotypes are typically acridid with all chromosomes acrocentric and of different lengths. Bivalent type profiles of the five species were constructed and comparisons of chiasma positions and frequencies made. The positions of chiasmata were not localized. The mean chiasma frequencies for the five species varied between 13.93 (Am. adspersus) and 17.5 (An. erythropus) .
