Zeugophora

Kunze, 1818

Zeugophora is a of in the , established by Kunze in 1818. The genus contains multiple distributed across the Northern Hemisphere, with particularly well-documented diversity in China. Species are , with and feeding on foliage of specific families. The genus is divided into subgenera based on morphological traits and host associations: subgenus Zeugophora primarily associated with Salicaceae, and subgenus Pedrillia with Celastraceae, Symplocaceae, and Lamiaceae. Male serves as a critical diagnostic tool for species identification.

Identification

-level identification relies heavily on examination of external male , including the lobe, median struts, , internal sac, and (9th abdominal ). Subgenus assignment can be inferred from : Salicaceae associates indicate subgenus Zeugophora, while Celastraceae, Symplocaceae, or Lamiaceae associates indicate subgenus Pedrillia. Detailed morphological comparison with described species is necessary for accurate determination.
