Abstract

In examining 1000 adult ♀♀ of Varroa jacobsoni Oudemans 1904, a specimen was found with a different body shape and with clerotinized hooks on the inside of the genitoventral shield. Its size resembles the shape of less adapted ectoparasites, and the hooks indicate a different mode of copulation, which is believed to be more primitive, the tocospermy. This kind of insemination by a spermathophore is believed to be more evolved than podospermy which is injection of sperm into openings near coxae III + IV of the ♀. Therefore one may conclude that this abnormal specimen is a mutant which reflects some features of an ancient type in the genus Varroa.
