Cixidia fusiformis
(Van Duzee, 1910)
Cixidia fusiformis is a of planthopper in the Achilidae, described by Van Duzee in 1910. It belongs to a family of fulgoroid insects commonly known as achilid planthoppers. The species has been recorded from western North America including British Columbia, Washington, Oregon, and California. Like other members of Achilidae, it is presumed to feed on fungal , though specific biological details remain poorly documented.

Identification
Achilidae can be distinguished from other planthopper by their reticulate wing venation, hind tibiae with prominent spines, and reduced ovipositor. Within the Cixidia, C. fusiformis is characterized by its (spindle-shaped) body form as indicated by its specific epithet. Definitive identification to level requires examination of male genitalia and comparison with type material.
Habitat
Recorded from mesic to semi-arid environments in western North America. Associated with woody vegetation in forested and scrubland where fungi occur.
Distribution
British Columbia, Canada; Washington, Oregon, and California, USA.
Diet
Presumed to feed on fungal , as is characteristic for the Achilidae; specific fungi unknown.
Ecological Role
Member of the decomposer , facilitating nutrient cycling through consumption of fungal .
Human Relevance
No known economic or agricultural significance. Occasionally encountered in general insect surveys and biodiversity assessments.
Similar Taxa
- Other Achilidae genera (e.g., Plectoderes, Bebaiotes)Similar reticulate wing venation and overall planthopper ; distinguished by differences in shape, wing proportions, and male genitalia structure.
- Cixiidae (cixiid planthoppers)Superficially similar body plan and size; distinguished by Achilidae having more extensively reticulate wing venation and different hind tibial spine arrangement.

Taxonomic Notes
The Achilidae has undergone significant taxonomic revision, with many historically misplaced in Cixiidae. Cixidia fusiformis was described from western North American material and has remained in Cixidia, though generic boundaries in Achilidae require continued study.
