Diagnosis and Specialized Morphology
Holoptilinae are sometimes referred to as feather-legged assassin bugs. Most members of this subfamily are characterized by:
1) long to very long setae on body and legs
2) forewing membrane usually with one closed cell or two longitudinal veins
3) antennal flagellomeres sometimes fused
4) some species with trichome and associated gland on abdominal
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).
