Description "Small, moderately robust. Sub-quadrate. Anterior margin broadly rounded, asymmetrically so in LV. Posterior truncate. Dorsal margin straight with anterior hinge ear and postero-dorsal spine in LV. Ventral margin straight to slightly convex. Dimorphic, males longer than females. Reticulum well-developed. Ventro-lateral ridge strong, continuous around anterior margin into ocular ridge without sudden decrease in relief. Dorsal ridge moderately well
developed, spinose. Bridge prominent, rectangular. Remainder of reticulum with relatively few bold, strong muri bounding large, open fossae. Posterior reticulum arranged into a box-like mural network with prominent sub-quadrate group of central fossae. Muri of equal horizontal and vertical emphasis. Fossae large, open and without secondary muri. Normal pore canal distribution as for the genus, solar sieve pores open. Inner lamella wide; details as for the genus. Paired, rounded frontal scars. Hinge holamphidont with posterior terminal tooth of the RV distinctly lobate." (Whatley et al., 1984: 276) [details]

Diagnosis "A small, well calcified species of Bradleya with a robust and well developed reticulum. Muri bold, of moderate to high relief, bounding large open fossae. Central pattern of posterior reticulum a quadrate group with muri of equal horizontal and vertical emphasis. Fossae lacking secondary subdivision. Non-foveolate. Bridge rectangular."
