Stichopogoninae
– posterior margin of compound eyes distinctly sinuate in ventral half (64)
– maxillary stipites divided medially (14)
– cornua on cibarium well developed in anteroposterior orientation (37)
– frons markedly and suddenly diverging laterally at level of antennal insertion (48)
– prosternum and proepisternum fused and prosternum broad above prothoracic coxae (74)
– anterior anepisternal setae absent (78)
– discal scutellar setae absent (99)
– proximal metathoracic tarsomere shorter than two following tarsomeres combined (122)
– female S8 plate-like and hypogynial valves separated (surrounded by membrane) (170)
– male gonocoxites fused to hypandrium (202)
– male ventral margin of dorsal aedeagal sheath strongly sclerotized (appearing entirely closed) (217)
The monophyly of Stichopogoninae has never been in doubt and has been recently corroborated by a phylogenetic analysis by Cannings (2002).
