Two specimens from SANCI are associated with isolated host puparia that were identified by F.C. Thompson (Smithsonian Institution) as belonging to Ischiodon aegyptius (Weidemann). Label data on another specimen, collected in Uganda and deposited in the BMNH, reads “parasite on syrphid larval predator of psyllid”; another specimen in the BMNH collected in Uganda has label data recording the host as “Ischiodon sp.”; these specimens lack host remains. A third specimen, collected in Senegal and deposited in the BMNH, reads “ex Ischiodon aegypticum”; this specimen lacks host remains.


This species closely resembles A. nicknacki, but can be differentiated from that species by the lack of well-developed antero-admedial signum struts (distinctly larger than surrounding rugae in A. nicknacki); distinct from A. pallida by the presence of rugae over the entire mesoscutum (shagreened in A. pallida); distinct from A. quadrus and A. paragi by the lack of additional antero-admedial signum struts (at least 2 in both A. paragi and A. quadrus); distinct from A. stygius by the lack of horizontal strigae on the mesoscutum.

Quinlan (1979) described six species that, in the present work, are considered synonyms of A. striaticeps. As with A. pallida, the morphology of this species is particularly difficult to interpret if insufficient lighting is used. Two key character systems employed by Quinlan (1979) are the sculpture of the mesoscutum and the shape of the scutellar acetabulum (referred to as the ‘apical depression of the scutellum’). In the case of the mesoscutal morphology, directional and non-directional light will reveal very different character states on the same specimen; careful examination of the mesoscutum of Quinlan’s (1979) holotypes revealed that several species described in that work were merely representing the morphological variation within A. striaticeps. A similar situation occurs with the scutellar acetabulum: the shape of the anterior and posterior margins of this structure vary from distinctly round to nearly straight, in the same specimen, solely dependent upon examination angle. In the preparation of the present study, this character was originally employed only to be excluded upon the discovery of this artifact.
