  • Autapomorphies:
    – posterior margin of compound eyes distinctly sinuate in ventral half (64)
  • Additional apomorphic character states:
    – 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)
  • Notes:
    The monophyly of Stichopogoninae has never been in doubt and has been recently corroborated by a phylogenetic analysis by Cannings (2002).
  • Stichopogonini: Lissoteles, Stichopogon

  • Autapomorphies:
    – male hypandrium and epandrium fused and connected by a narrow sclerite proximally (201)
    – male subepandrial sclerite with short, stout macrosetae on the distal margin ventrally (209)
  • Additional apomorphic character states:
    – mystacal setae tightly packed and forming a distinct shield (8)
    – postpedicel tapering distally (54)
    – one seta forming notopleural setae (88)
    – medial setae on posterior scutum erect and directed dorsally to anteriorly (96)
    – setae on anteroventral prothoracic tibiae absent (105)
    – prothoracic and mesothoracic coxae directed distinctly posteriorly (109)
    – blunt protuberance on anterior metathoracic coxae (113)
    – male cerci fused to a single sclerite (212)
