Purshivora brevistigmata
Purshivora brevistigmata is a of jumping plant louse in the Psyllidae. It belongs to a associated with plants in the genus Purshia, commonly known as bitterbrush or cliffrose. The species has been documented in western North America. Like other psyllids, it is a small sap-feeding insect with host-specific associations.

Identification
Distinguishing P. brevistigmata from other Purshivora requires examination of genitalia and wing venation patterns. The specific epithet 'brevistigmata' suggests reduced or short wing stigma (a thickened colored area on the forewing), which may serve as a diagnostic character. Identification to species level generally requires taxonomic knowledge and reference to original species descriptions.
Appearance
Small insect, typical of Psyllidae, with body length likely under 5 mm. Winged possess membranous wings held roof-like over the body. Coloration and detailed require specimen examination; specific distinguishing features from are not well documented in accessible literature.
Habitat
Associated with Purshia plants, which grow in arid and semi-arid shrublands, sagebrush steppe, and pinyon-juniper woodlands of western North America. are characterized by well-drained soils and moderate to low precipitation.
Distribution
Western North America, with records from the United States. Specific range boundaries are poorly documented due to limited survey effort and taxonomic study.
Seasonality
activity likely coincides with plant , particularly during periods of new leaf growth. Exact timing undocumented; psyllids in similar climates often show spring to early summer activity peaks.
Diet
Feeds on phloem sap of Purshia (Rosaceae). plant specificity is inferred from name and known of related Purshivora species.

Taxonomic Status
The was described by Crawford in 1914. It has received limited subsequent taxonomic attention, and modern redescriptions or phylogenetic studies are lacking. The Purshivora contains multiple species, most poorly known.
Research Needs
Basic including precise range, geographic distribution, and seasonal remain undocumented. Molecular data and modern morphological redescriptions would improve identification capacity.
