Cyrtolobus vanduzii

Distinguished from other Cyrtolobus species by specific configuration of pronotal projections and tubercles; exact diagnostic characters require examination of type specimens and comparison with congeners. The pronotal shape differs from the more widely distributed Cyrtolobus discoidalis and other eastern North American species.

Pronotum with distinct elevated projections; body form compact with enlarged pronotum covering much of thorax and abdomen. Coloration and specific pronotal morphology consistent with genus Cyrtolobus, which exhibits diverse pronotal shapes among species.

Associated with woody vegetation in arid and semi-arid regions; specific host plant associations not well documented but likely tied to desert scrub and chaparral vegetation typical of its range.

Southwestern United States: documented from Arizona and California. Distribution appears restricted to this region based on available collection records and iNaturalist observations.

Adult activity period not precisely documented; likely active during warmer months when host plants are in active growth, consistent with patterns observed in related Membracidae.

Phloem-feeding herbivore; likely contributes to nutrient cycling through honeydew production and serves as prey for parasitoid wasps and other natural enemies, as documented for other Membracidae.

• Cyrtolobus discoidalisOverlaps in some western range areas; differs in pronotal shape with more disc-like central elevation versus the projection structure in C. vanduzii
• Other Cyrtolobus speciesGenus members share general body plan but differ in specific pronotal tubercle arrangement, size, and geographic distribution
• Genera in Smiliinae (e.g., Heliria, Glossonotus)Similar compact body form with enlarged pronotum; distinguished by genus-specific pronotal morphology and taxonomic placement
