We recently reported that most of the Drosophila species of the obscure group were unable to mount cellular capsules and no lamellocyte was ever found in the hemolyraph of any of the tested species. Only three species were able to encapsulate, despite lacking lamellocytes. Their encapsulation ability was always associated with the presence of an unpreviously described kind of capsule-forming immunocytes designated as «atypical hemocytes». Here, we describe the ultrastructural and functional characteristics of this type of hemocyte. We show that these cells share many ultrastructural and morphological features with Drosophila melanogaster plasmatocytes, although they are involved in the formation of the external layers of the cellular capsule, a functional property exhibited by lamellocytes in D. melanogaster. Due to the high number of pseudopodes in these cells, we suggest to name them «pseudopodocytes». After structural and functional characterization of these atypical hemocytes, their ambiguous status between plasmatocytes and lamellocytes is discussed.
