Diagnosis and Specialized Morphology
Holoptilinae are sometimes referred to as feather-legged assassin bugs. Most members of this subfamily are characterized by:
- long to very long setae on body and legs
- forewing membrane usually with one closed cell or two longitudinal veins
- antennal flagellomeres sometimes fused
- some species with trichome and associated gland on abdominal sternum 3
According to Wygodzinsky & Usinger (1963), Holoptilinae is comprised of about 80 species (15 genera) in three tribes: Holoptilini, Dasycnemini, and Aradellini. Wygodzinsky & Usinger also produced a key to the genera in the same publication.
Most holoptiline species occur in the southern Palearctic, Old World tropics, and Australia (Malipatil 1985, Schuh & Slater 1995. One genus, Neolocoptiris Wygodzinsky & Usinger, is found in Guyana (Schuh & Slater 1995).
