1. Aprostocetus nigriventris (Girault)

Bouček (1988) recorded A. gala from Australia, placed Epitetrastichus nigriventris Girault 1913 in synonymy with it, and placed Tetrastichus xanther Girault 1913 and Epitetrastichus xanther hilli Girault 1915 in Aprostocetus , where he suggested they might also be synonyms of A. gala . However, Australian specimens determined as A. gala by Bouček (in ANIC) and examined by JL differ from A. gala , and Australian records of A. gala should be referred to Aprostocetus nigriventris (Girault) , which is here removed from synonymy under A. gala and treated as a valid species. Further study will be required to determine if Aprostocetus xanther ( Girault 1913) and Aprostocetus xanther hilli ( Girault 1915) should also be synonymized with A. nigriventris .
