Adelea
The name is derived from the Greek word adēlos (meaning unseen).Adelea together with the genera Adelina and Ithania form the subfamily Ithaniinae.This subfamily was created in 1947 by Ludwig to accommodate these genera of eimeria that share certain morphological features and infect the digestive tracts of insects.[1] The genus Adelina was created by Hesse in 1911 because of morphological differences between the species.The species in this genus are parasitic on arthropods and have two sporozoites in each sporocyst.
