Genus Propebrevitrichia, new genus 



Type-species, Propebrevitrichia turneri, new species. The genus 

 Propebrevitrichia closely resembles the genus Brevitrichia; it differs in 

 the point of branching of vein R4 which forks from beyond the middle 

 of the closed cell R5 and by the elongate pointed female eighth ster- 

 num which is longer than the tergum. The members of this genus are 

 found in the Ethiopian region.
