Chris Cohen on the 3 genera of Asilidae in NZ

Well, you only have three commonly-encountered genera in NZ, all of which are probably not congeneric with their European counterparts.

"Neoitamus": antennae ending in narrow, tapering element (=Asilinae); ovipositor consisting of multiple sclerotized segments (giving the posterior abdomen a "jagged" appearance) and ovipositor rounded in cross-section; male genitalia relatively large and bulbous; habitus relatively large and robust (compared to the other two genera).

male: https://www.inaturalist.org/observations/64002149

"Cerdistus": antennae ending in narrow, tapering element (=Asilinae); female ovipositor laterally-compressed and blade-like, consisting of only the terminal segment; male genitalia not bulbous; habitus relatively small and gracile.

male: https://www.inaturalist.org/observations/38381577

"Saropogon": terminal segment of antennae broad, cylindrical throughout; female ovipositor blunt-ended and with acanthophorite spines; male genitalia fairly nondescript; habitus robust.
