Diagnosis and Specialized Morphology
Emesinae are sometimes referred to as thread-legged bugs. Species of this subfamily are characterized by:
1) elongate, slender body
2) thread-like legs
3) absence of fossula spongiosa
4) pretarsal claws of front legs often asymmetrical
5) foreacetabulum opens anteriorly
Wygodzinsky (1966) produced a monographic revision of the subfamily and recognized six tribes (86 genera): Collartidini, Leistarchini, Emesini, Ploiariini, Deliastini, and Metapterini. Wygodzinsky considered the Emesinae as the sister group of the Saicinae.
Emesinae diversity is highest in the tropics and on Pacific islands (Schuh & Slater 1995).
