2. Empodia with small hook (om) near base; centrally, between setae c1 and d1, striae form an open “U”-pattern; setae ex narrowly lanceolate................................................................. A. smileyi Kaźmierski, 1998

- Empodia without hooks; centrally, between c1-c1 and d1-d1 sections, striae form a distinct “C”-pattern; setae ex spatulate.......................................................................................................3
