Emesopsis infenestra is a species of thread-legged bug in the family Reduviidae, subfamily Emesinae. It was described by the entomologist Pedro Wygodzinsky in 1966.

Description
As a member of the genus Emesopsis, E. infenestra is characterized by a slender, elongated body form typical of the Emesinae (thread-legged bugs). Specific diagnostic features separating E. infenestra from congeners include details of the genital capsule structure, antennal segment proportions, and leg spination patterns documented in the original description and subsequent taxonomic keys. The specific epithet infenestra is derived from Latin (in- + fenestra, meaning "without a window"), likely referencing a morphological feature such as an absence of a fenestra (window-like opening or transparent area) on the hemelytra or another sclerite, though the exact etymological reasoning is specified in the original publication.
Distribution
The type locality for Emesopsis infenestra is in Argentina (specifically the province of Misiones). Its known distribution is primarily restricted to this region in South America.
Ecology and Behavior
Like other members of the subfamily Emesinae, E. infenestra is presumed to be predatory, feeding on small arthropods. Emesinae are often associated with spider webs (kleptoparasitism) or found on vegetation, rocks, or in leaf litter, where they walk on their elongated mid and hind legs while using the raptorial forelegs to capture prey. Specific behavioral observations for E. infenestra are limited in published literature.
