Etymology Not stated. The specific epithet oculata (masculine: oculatus) is a Latin adjective meaning 'having eyes', and refers presumably to the presence of irregular rows of dark eyespots on the peristomial ring of the species: ''S. oculata differs from S. pacifica, the only known species in the genus, in having numerous peristomial eyespots'' (Hartman, 1944: 275). [details]

Taxonomy According to Nogueira & Hutchings (2003) Spinosphaera oculata probably does not belong to this genus, as it lacks some important morphological features typical of Spinosphaera. This way, on the posterior thoracic chaetigers it lacks (against having) alimbate and serrate chaetae with blade at an angle with the shaft, and 'spinosphaera chaetae', on the anterior and posterior tier of the bundle, respectively, it has 41 pairs of notopodia (against 20-23), and the uncini arranged in double rows end close to the pygidium (against ending near segment 44, where notopodia end). The correct taxonomic placement of the species is subordinate to an ongoing phylogenetic analysis of the group, in preparation by the same authors. [details]
