Centroclisis sp. (27-7-19 Harvard MNH)

Description:

This antlion was on display at Harvard natural history museum, Boston, Massachusetts. After consulting several experts, the expert in African antlions Marvyn Mansell concluded that it belongs probably to genus Centroclisis. Tags are written with "Ainsworth, W. T. July 20, 82". I failed to locate any place called Ainsworth in Africa, and this is most probably the surname of the collector. A second tag is handwritten with something that reads like "Conge..." or "Congi..." (cannot read the full word). I supposed that is an identified species with the specific epithet of congensis, congica, congicus or congolensis, but every search of antlions with matching specific epithets, and found none. I also checked one by one all species of Centroclisis, most have not images in Internet but all those what have images are not coincident with the strange club-shaped, not falcated antennae of this specimen.So, any help will be very welcome for get the specific ID.
