Description Small to medium. Elongate, sub-ovate to subrectangular. Anterior margin broadly rounded, posterior truncate to weakly caudate. Dorsal margin straight without prominent hinge ears; ventral margin straight to gently convex. Sexually dimorphic males lower than females. Reticulate. Ventro-Iateral carina of high relief, narrowing posteriorly and terminating in a prominent laterally directed spine. Remainder of valve surface non-spinose. Ocular ridge well-developed, sinous. Dorsal carina of equivalent relief to remainder of reticulum. Muri of moderate relief rounded, equally developed both anteriorly and posteriorly. Posterior reticulum with a subquadrate group of 4 fossae, the bounding muri of this group being of equal horizontal and vertical emphasis. Fossae subdivided by virtually aligned secondary muri. Bridge sub-rectangular. Weakly foveolate. Normal pore canal distribution as for the genus, solar sieve pores celate. Juvenile ins tars lightly calcified with highly developed secondary reticulation. All internal details as for the genus, posterior terminal tooth of RV only indistinctly lobate. [details]

Description Small to medium. Elongate, sub-ovate to subrectangular. Anterior margin broadly rounded, posterior truncate to weakly caudate. Dorsal margin straight without prominent hinge ears; ventral margin straight to gently convex. Sexually dimorphic males lower than females. Reticulate. Ventro-Iateral carina of high relief, narrowing posteriorly and terminating in a prominent laterally directed spine. Remainder of valve surface non-spinose. Ocular ridge well-developed, sinous. Dorsal carina of equivalent relief to remainder of reticulum. Muri of moderate relief rounded, equally developed both anteriorly and posteriorly.

All internal details as for the genus, posterior terminal tooth of RV only indistinctly lobate. [details]

Diagnosis Elongate, subrectangular to subovate and weakly caudate species of Bradleya with welldeveloped reticulum. Muri distinct, rounded, of approximately equal development across both the anterior and posterior reticular fields. Dorsal carina of equivalent relief to the other muri; bridge strong, sub-rectangular. Juvenile instars lightly calcified with subdued primary but well developed secondary reticulation. [details]

Etymology L. Referring to the close similarity of this species to B. dictyon (Brady) 1880 [details]
