Ploiaria

Ploiaria is a cosmopolitan genus of thread-legged bugs (Emesinae). There are presently about 130 described species.

== Description == Ploiaria can be recognised by the head without ventral spine-like setae, the medially emarginated posterior margin of the prosternum, the posterior pronotal lobe covering only the extreme base of the mesonotum, the scutellum and metanotum lacking spines, the profemora lacking a process with several spine-like setae, and three-segmented protarsi. There is great variation in wing development between different species and within species, with macroptery (developed wings), brachyptery (reduced wings) and aptery (winglessness) all occurring in the genus.
