Diagnosis "Carapace subrectangular to subquadrate with broadly rounded anterior margin and squared posterior margin without noticeable caudal process; dorsal and ventrolateral carinae. Surface smooth to grossly reticulate with celate overgrowth (in the type-species); the reticular pattern is grid like rather than radiate and consistent within species, with variation due to increased coarseness of some muri and loss of others. Most species have traces of a bridge or box-girder construction (Figure 9) within the pat- tern of the anterior field of the reticulum, extendirg from the region of the suppressed muscle-scar node (absent in smooth forms) to the ocular ridge, which extends from the position of the eye tubercule (absent in blind species) to join with the ventrolateral ridge. In some species a median ridge, postjacent to muscle-scar node, is formed from emphasis of one set of longitudinal muri and may be joined with the dorsal carina at the posterior to form a posterodorsal loop. This feature becomes well developed as the lower element of the bridge decreases in size. Several species having this feature are considered together as the new subgenus Quasibradleya. Hinge hemi- to holamphidont commonly with a lobed posterior tooth; vestibule absent, duplicate broad. Muscle-scar pattern thaerocytherid with two frontal scars. First antennae with five segments (IV and v fused), epipodite with five "fingers," knee apparatus in thorassic legs, exopodite large in second antennae (Figures 15 and 16)." (Benson, 1972: 30)

Lectotype The lectotype of Bradleya arata is a juvenile and lacks morphologcial characters typical of the genus Bradleya, as can be seen in the SEM attached to this species. This is a very unfortunate situation, since this species is the type species of the genus. [details]
