Description
Table 3 (continued). Tabular key to all species of the genus Ophiuroglypha Hertz, 1927, compiled from the literature. For convenience, the second oral tentacle pore is here labelled as the 1 st pore, because it is the first visible pore along the arm, the actual first pore being placed laterally in the oral plates (= jaw) and both ventral tentacle scales and adoral shield spines in second oral tentacle pore labelled as tentacle scales. Abbreviations: ASE = arm segment; DAP = dorsal arm plate; LOP = lateral oral papillae; TS = tentacle scale; VAP = ventral arm plate; VMT = ventralmost tooth.
