fine and divergent (? Aprotheca). Intermediate abdominal tergites with or 

 without discal setae ........... 14 



13 Upper half of parafacials with stiff setulose hairs. Facial ridges bare and widely 



visible in profile. Eyes densely haired. Vibrissae well above level of epistomal 

 margin. Upper occiput with an irregular row of black setulae behind the

AUSTRONILEA Crosskey

TERETROPHORA Macquart 



* The genus Aprotheca is known only from Macquart's types that are in very bad condition. They 

 appear to have only three postsutural dorsocentral pores and the dc complement in Aprotheca may 

 be 3 + 3.
