Table 3 in Deepest known novel species of the genus Ophiuroglypha Hertz, 1927 (Echinodermata: Ophiuroidea) from the central rift zone, Philippine Sea

Table 3 (continued on next two pages). 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.
