Macropeza :

- The posterior tentorial pit attached by short extension to the postoccipital foramen (also in Austroconops ) (posterior tentorial pit on postoccipital foramen or more ventral from postoccipital foramen).

- Male flagellomeres 1–8 each with two elongate spines or short plume setae.

- Female flagellomeres 1–9 with numerous and thick setae. The feature is nearly unique in the family but is also known in Stenoxenini (see under “Uncertain Character States”).

- Male with lateral scutal apodemes elongate. This feature is unique within the group Echinoheleini + Heteromyiini + Hebetulini + Johannsenomyiini + Sphaeromiini + Palpomyiini + Stenoxenini . Those of females are very short and widely spaced (see character 65).

- Female wing with 6–8 elongate costal setae basal to the level of the arculus, significantly longer than those more distally and with few on the costa just distal to the level of the arculus. Otherwise, only female Jenkinshelea have elongate more basal setae but in that genus, there is a dense row of costal setae distal to the level of the arculus.

- Larva with dorsal and lateral setae on last abdominal segment plumose ( Szadziewski & Dominiak 2007). The feature is unique in the family but is known for only one species.
