A new species of Paragrillotia Dollfus, 1969, P apecteta n. sp., is described from the spiral valve of Hexanchus nakamurai Teng, 1962, from Lifou, New Caledonia, South Pacific. The new species differs from congeners in its distinctive basal armature with characteristic enlarged hooks, the presence of seven hooks Per principal row and the presence of two or three rows of intercalary hooks. Pseudogrillotia spratti Campbell and Beveridge, 1993 is redescribed from specimens collected from Negaprion acutidens (Ruppell, 1837) from New Caledonia. The fully mature segment is described for the first time. The presence of a chainette on the external surface of the tentacle indicates that the species belongs Paragrillotia rather than to Pseudogrillotia Dollfus, 1969 as Paragrillotia spratti (Campbell and Beveridge, 1993) n. comb. Both species represent the first records of the genus Paragrillotia from the southern hemisphere.
