Harpactira differences

[Ceratogyrus]

Quick difference between Harpactira and other genera found in Southern Africa:





Basically Harpactira have a patch of bristles (scopulae) on the inside and outside if the chilecerae whereas Ceratogyrus, Harpactira, Pterinochilus and Idiothele only have on the outside margin of the chelicerae. Brachionopus and Harpactirella don't have any scopulae on the chelicerae.
