oa Journal of the Entomological Society of Southern Africa - Meiosis in the Eastern Cape grasshopper Phymateus leprosus (Orthoptera: Pyrgomorhphidae)
The meiotic process in Phymateus leprosus is descriptionbed for the first time. The diploid chromosome number in males and females is 19 (18 + XO) and 20 (18 + XX) respectively. Chromosomal analysis of field-collected grasshoppers revealed no meiotic abnormalities, thus suggesting that chromosomal rearrangements have played a minor role in the karyotype evolution of this species.
