A record of Randiella from New Caledonia,the first known occurrence of the marine interstitial family Randiellidae (Annelida; Oligochaeta) in the South Pacific Ocean

Five specimens morphologically indistinguishable from Randiella caribaea Erséus and Strehlow, 1986, previously known only from the Caribbean in the Atlantic Ocean, are reported from a sandy beach at Touhou, New Caledonia. The new material reveals that R. caribaea and probably also the closely related R. minuta Erséus and Strehlow, 1986 have dorsal spermathecae, an assumedly apomorphic condition vis-à-vis the lateral spermathecae of the other species of Randiellidae. The number and position of the gonads in this family are unclear, but the new material of R. caribaea appears to have at least one testis in segment X and one ovary in segment XII.
