Schizohelea :

- Male frontoclypeus with dorsolateral flange of cuticle attached to anterior tentorial pit short, strongly-developed, darkly pigmented (longer, weaker and unicolourous with frontoclypeus in all other earlier lineages; see character 26 for further developments).

- Male gonocoxite with medial lobe (distal but near the ventral apodeme) bearing setae. The feature, unique within at least Ceratopogonidae , was discussed by Borkent & Picado (2008). Although Remm (1967, 1980, 1993) shows the lobe in his illustrations of S. pekae (Remm) and S. armata (Remm) , it is not shown for S. spathulata (Remm) and S. lampropeza (Remm) is shown with an apparently bare lobe. The male of S. incert a (Clastrier) is unknown. As such it is possible that this feature is a synapomorphy of only some species of Schizohelea . There are significant differences in the male genitalia of S. leucopez a (Meigen) as presently understood, indicating the presence of more than one species and all of these had the derived condition. I have undescribed species of Schizohelea from New Zealand with a strongly developed and setose gonocoxal lobe.
