Description "This species is the only one known which is nude or smooth in the terminal regions on the carapace, and in the same adult stage has coarse reticular elements over the rest of the carapace. This difference in development in the reticulum is known in early instars of Poseidonamicus, new genus (whose fossae are filled in), but not observed to such an extreme degree before in Bradleya. The earlier ins tars of Bradleya dictyon (Figure 15) have the reticulum somewhat incompletely developed near the anterior margin, suggesting that B. japonica, new species, may be neotonous. The pattern of the reticulum is irregular, especially anterior to the muscle-scar region. The species appears to be transitional in form between the boldly reticular species Bradleya albatrossia, new species, and the smooth B. nuda, new species. All three of these species are common to the western Pacific. Attention is called to a murus that extends downward and slightly toward the anterior from the high peak of the dorsal carina. This same murus, one of the more prominent on the central carapace of B. japonica is clearly identifiable on B. nuda. Both species also have a posteriorly directed process on the posterior cardinal angle, as also does B. paranuda, new species." (Benson, 1972: 40) [details]

Description "This species is the only one known which is nude or smooth in the terminal regions on the carapace, and in the same adult stage has coarse reticular elements over the rest of the carapace. This difference in development in the reticulum is known in early instars of Poseidonamicus, new genus (whose fossae are filled in), but not observed to such an extreme degree before in Bradleya. The earlier ins tars of Bradleya dictyon (Figure 15) have the reticulum somewhat incompletely developed near the anterior margin, suggesting that B. japonica, new species, may be neotonous. The pattern of the reticulum is irregular, especially anterior to the muscle-scar region. The species appears to be transitional in form between the boldly reticular species Bradleya albatrossia, new species, and the smooth B. nuda, new species. All three of these species are common to the western Pacific. Attention is called to a murus that extends downward and slightly toward the anterior from the high peak of the dorsal carina. This same murus, one of the more prominent on the central carapace of B. japonica is clearly identifiable on B. nuda. Both species also have a posteriorly directed process on the posterior cardinal angle, as also does B. paranuda, new species." (Benson, 1972: 40) [details]

Diagnosis "Distinguished from other species of Bradleya by the incomplete development of the reticulum in the anterior and posterior regions near the margin, the confused pattern of the reticulum in the anterior, its broad ventrolateral carina, and its foreshortened and peaked dorsal carina." (Benson, 1972: 40) [details]
