Gonatopodinae is a of dryinid comprising 17 , including the diverse genus Gonatopus. Females are wingless and -like in appearance, while males possess wings. A defining feature of females is the presence of a chela (pincer-like structure) on each foreleg, used to capture . All known are of leafhoppers (Cicadellidae).

Identification
Females distinguished from other dryinid by the combination of winglessness, -like body form, and chelate forelegs bearing a pincer-like structure. Males are winged and do not possess the chelate forelegs of females. is pronounced, making association of males with females difficult without molecular or rearing evidence.
Habitat
Blackwater floodplain forests (igapó) in Amazonia; wetlands including Tamarix stricta stands in arid regions (Sistan, Iran).
Distribution
distribution including: Brazil (Amazonas, São Paulo), Iran (South-Eastern Iran, Hamoon international wetlands), Japan, and broader Palearctic, Neotropical, and Oriental regions.
Host Associations
- Cicadellidae - All Gonatopodinae are of leafhoppers. Specific records include: Amplicephalus sp., Copidinomus vittulatus, Stirellus picinus, Graminella striatella, Metadelphax argentinesis, and leafhoppers associated with Tamarix stricta.
Life Cycle
Postembryonic development documented for Gonatopus lunatus; stages develop within leafhoppers.
Behavior
Females use chelate forelegs to grasp and capture leafhoppers. poses challenges for associating males with females, often requiring or rearing from hosts for confirmation.
Ecological Role
of leafhoppers (Cicadellidae); contributes to of these herbivorous insects in diverse including wetlands and floodplain forests.
