Genus Ascaloptynx

Right, however I have seen Haplogenius appendiculatus as a synonym for the one North American species, I think, see for instance this excerpt of a book from TAMU. (That is what I meant to say in the guide, not that the genera were synonymous.) Can you clarify the synonymy in a comment on the guide page for the species?

The combination "Haploglenius appendiculatus" for this species dates back to at least 1842. However, the currently-accepted combination for this species by neuropteran specialists is "Ascaloptynx appendiculata". The matter of a full synonymy for the species is complicated, and one that is, I think, beyond the scope of the BugGuide. The species-group name "appendiculatus" [-us, -a, -um] has been used in the literature in combination with at least five genus-group names over the years, often with an incorrect gender ending. In addition, there are at least two synonymous species-group names -- furcifer and juvenilis -- which have themselves been placed in other genera -- that would also figure in the synonymy. Incidently, there is only one extant species in this genus, which is widespread in the southern USA and Mexico. A second fossil species has been described from France.
