Type species. Allenbycimbex morrisae n. sp.

Diagnosis. Distinguished from Cenocimbex by R lacking dark triangular sclerite before base of pterostigma reaching 1-Rs+M near 1m-cu; wing narrower (length/width ca. 3.0 as reconstructed) [ Cenocimbex : 2.5]; cell 3rm long (2rm to 3r-m distinctly longer than length of 3r-m); hind wing with m-cu placed much basally than in Cenocimbex ; distinguished from Leptostigma by pterostigma broad, maximum height distinctly exceeding height of C to R basal to pterostigma.

Locality and age. Vermilion Bluffs Member of the Allenby Formation south of the village of Princeton, British Columbia, Canada; mid-Ypresian.

Species included. Type only.

Etymology. Named for the Allenby Formation, where its only specimen was found. The name is to be treated with masculine grammatical gender since it is derived from Cimbex (see Taeger et al. 2010: 188).
