Its genitalia also differs from other " Dialictus " since its gonostylus is nearly equal in length to its gonocoxite with the additional shape and position of the hairs.
2.
The phylogeny casts significant doubt upon the monophyly of the subfamily Octolepidoideae, and upon the monophyly of the informal " Octolepis " and " Gonostylus " groups, but this result had only weak statistical support.

Additionally, the " Amegilla " genus is strongly characterized by several autapomorphies, including a gonostylus, the male phallic organ, that is fused to the gonocoxite, or interior region of copulation, and a curved maxillary palpus with distinctive surrounding fringe.
4.
Corydalinae is distinguished from closely related clades by the following synapomorphies ( with exceptions in a few species ) : quadrate head with a postocular spine, ridge, and plane, non-pectinate antennae, four crossveins between the radius and the radial sector, and distinctive male terminalia with a well developed ninth gonostylus.
