Atomoscelis onustus
(Fieber, 1861)
Atomoscelis onustus is a of plant bug in the Miridae. It exhibits a broad Holarctic distribution spanning the Palearctic and Nearctic regions. The species has been documented across diverse environments from the western Mediterranean and Middle East to western North America. Like other members of the , it is presumed to be phytophagous, though specific plant associations remain poorly documented.

Identification
Members of the Atomoscelis are small, somewhat oval plant bugs with relatively short . Specific diagnostic features separating A. onustus from require examination of male genitalia and detailed structural characters. The may be distinguished from similar mirids by the combination of its small size, general body proportions, and geographic origin in combination with structural features of the genital segment.
Habitat
Recorded from arid and semi-arid environments including Mediterranean scrub, steppe, and desert-edge . North American occur in sagebrush and desert shrub . Specific microhabitat preferences are poorly documented.
Distribution
Holarctic distribution: Palearctic records from Spain, Portugal, Canary Islands, Madeira, Morocco, Algeria, Tunisia, Spanish Sahara, Macedonia, Turkey, Israel, Iraq, Iran, and southern Siberia (Tuva). Nearctic records from western United States: California, Nevada, and Utah.
