Parancistrocerus bicornis ceanothi

(Rohwer, 1912)

Parancistrocerus bicornis ceanothi is a of mason wasp in the Eumeninae. It belongs to a of small, solitary cavity-nesting that provision their nests with paralyzed caterpillars. The subspecies name "ceanothi" suggests a potential association with Ceanothus plants, though this relationship requires verification. Like other Parancistrocerus , it likely nests in pre-existing cavities such as hollow twigs or borings.

Identification

This is distinguished from other P. bicornis subspecies by subtle morphological features, though specific diagnostic characters are not documented in the provided sources. The Parancistrocerus is notoriously difficult to separate from the closely related genus Stenodynerus based on images of live specimens; even microscopic examination of actual specimens presents identification challenges.

Host Associations

Ceanothus - potential plant epithet 'ceanothi' suggests association, but not confirmed in sources

Similar Taxa

More Details

Taxonomic note

The epithet 'ceanothi' (derived from Ceanothus) appears in the Catalogue of Life and GBIF as an accepted subspecies, but no detailed description or diagnostic features were found in the provided sources. The parent Parancistrocerus bicornis was originally described by Rohwer in 1912.

Identification challenges

According to Eric's observations, Parancistrocerus and Stenodynerus are so similar that live specimens photographed in the field cannot be reliably separated to , and even microscopic examination of collected specimens presents difficulties.
