Ossiannilssonola mcateei
Christian, 1953
Ossiannilssonola mcateei is a of leafhopper in the Cicadellidae, Typhlocybinae. It is a small, delicate insect characteristic of the Typhlocybini tribe. The species was described by Christian in 1953 and is known from scattered records across eastern North America. It belongs to a of specialized leafhoppers that feed on plant phloem.

Identification
Identification to level requires examination of male genitalia, specifically the structure of the and pygofer, which are diagnostic in Typhlocybinae. The Ossiannilssonola is distinguished from related genera by features of the shape and wing venation, particularly the reduced number of in the forewing. Separation from congeneric species such as O. nigrocincta requires detailed comparison of genitalic structures. No reliable external field characters have been established for distinguishing this species from close relatives.
Appearance
As a member of Typhlocybinae, this is extremely small and slender, with reduced wing venation typical of the . The is broadly rounded with the vertex extending forward. Coloration is likely pale or translucent, as is common in the , though specific patterning has not been documented in available sources. Wings are held roof-like over the body at rest. The hind legs bear rows of setae adapted for jumping.
Habitat
Records indicate occurrence in deciduous forest and woodland in eastern North America. Specific plant associations have not been documented, but related in the feed on woody angiosperms. The species has been collected in both upland and lowland forest settings.
Distribution
Documented from Illinois, Kentucky, Maryland, New Hampshire in the United States, and Ontario in Canada. The distribution appears to span the northeastern and north-central regions of North America, though records are sparse and the full range remains poorly characterized.
Seasonality
records span from June to September, suggesting a single with summer activity. Specific data are limited due to few collection records.
Ecological Role
As a phloem-feeding leafhopper, this contributes to nutrient cycling in forest and serves as prey for insectivorous birds, spiders, and other arthropods. densities appear low based on limited collection records.
Human Relevance
No documented economic or agricultural significance. The is not known to plant or cause damage to crops or ornamental plants.

Taxonomic History
The Ossiannilssonola was established to honor the Swedish entomologist Frej Ossiannilsson, who made significant contributions to the study of Typhlocybinae. The specific epithet mcateei honors an American entomologist, likely R. A. McAtee, who worked extensively on North American Hemiptera.
Collection Rarity
With only five observations in iNaturalist and scattered museum records, this appears genuinely rare or undercollected. The difficulty of identifying small typhlocybine leafhoppers to species level without dissection contributes to underrepresentation in biodiversity databases.
