Phymatopsallus
Knight, 1964
Phymatopsallus is a of plant bugs ( Miridae, Phylinae) to western North America. The genus was established by Knight in 1964. A 2006 revision significantly expanded understanding of the group, describing 9 new genera and 15 new within the Phymatopsallus group. These are small, soft-bodied true bugs with the typical mirid of slender bodies and with distinct membranous apices.

Identification
Members of Phymatopsallus can be distinguished from related Phylinae by genitalic characters, particularly male paramere structure and female genital chamber . The 2006 revision established new genera based on phylogenetic analysis, separating previously conflated into distinct lineages. External morphology is generally conservative within the group, making dissection and examination of genitalia necessary for reliable identification to species.
Distribution
Western North America. The is to this region, with distributed across various in the western United States and adjacent areas of Canada and Mexico.

- Other Phylinae generaPhymatopsallus was historically confused with related , leading to the 2006 revision that erected 9 new genera to accommodate phylogenetically distinct lineages previously included within Phymatopsallus sensu lato. Accurate identification now requires examination of male and female genitalia rather than external characters alone.

Taxonomic revision
The 2006 revision by Weirauch and Schuh (Bulletin of the American Museum of Natural History 301:1-115) fundamentally reorganized the Phymatopsallus group. Prior to this work, now placed in 9 additional were considered congeneric with Phymatopsallus. The revision included phylogenetic analysis, biogeographic reconstruction, and plant documentation where available.
