Original Description
Test moderately large in size, polygons of the cancellate pattern wide, usually pentagonal, some hexagonal; a low trochospire of two volutions; chambers ovate to subspherical; increasing rapidly in size, four in last whorl; last chamber flattened, elongate, and large, about half size of the test from which it is separated by a wide deep suture; sutures distinct, more or less radial; umbilicus narrow; primary aperture interiomarginal, extraumbilical-umbilical.

Etymology: from the Weno Formation of North Central Texas.

Extra details from original publication
Remarks: Favusella wenoensis, n. sp., differs from all other species of Favusella by its large flattened last chamber which is often half the size of the test and separated from the rest of the tste by a wide, deep suture. Generally, the elongate, flattened shape of the test is highly diagnostic.
Range: Upper Albian: lower part of the Hedbergella delrioensis Snbzone.
Occurrence: This species appears to be restricted to the Weno Formation of the North Central Texas area.
