(Paykull, 1800)

Eutrichapion viciae is a small pear-shaped weevil in the Brentidae. The was described by Paykull in 1800. It belongs to a of weevils characterized by their distinctive body form and elongated rostrum. The specific epithet 'viciae' suggests an association with Vicia (vetch) plants, though this relationship requires confirmation.

Identification

Distinguished from other small weevils by its pear-shaped body and membership in Brentidae (formerly often placed in Apionidae, now treated as Apioninae within Brentidae). The Eutrichapion is separated from related genera by rostral and antennal characters, though specific diagnostic features for E. viciae versus are not detailed in available sources. Examination of genitalia may be required for definitive identification.

Similar Taxa

  • Other Eutrichapion species share the pear-shaped body form and elongated rostrum; require detailed examination of rostral proportions, antennal insertion points, and genitalia for separation.

Family placement

NCBI lists this under Apionidae, while GBIF and other sources place it in Brentidae. This reflects ongoing taxonomic debate: Apionidae is now widely treated as Apioninae within Brentidae, though some databases maintain separate family status.
