- This study describes the fauna of the marine enchytraeid genus Grania at two locations on the Australian Great Barrier Reef: Lizard and Heron Islands. Collections were made from 1979 to 2006, yielding four new species: Grania breviductus sp. n., Grania regina sp. n., Grania homochaeta sp. n. and Grania colorata sp. n.. A re-description of Grania trichaeta Jamieson, 1977 based on new material is also included, along with notes and amendments on G. hyperoadenia Coates, 1990 and G. integra Coates & Stacey, 1997, the two latter being recorded for the first time from eastern Australia. COI barcode sequences were obtained from G. trichaeta and G. colorata and deposited with information on voucher specimens in the Barcode of Life database and GenBank; the mean intraspecific variation is 1.66 % in both species, while the mean interspecific divergence is 25.54 %. There seem to be two phylogeographic elements represented in the Great Barrier Grania fauna; one tropical with phylogenetic affinities to species found in New Caledonia and Hong Kong, and one southern (manifested at the more southerly located Heron Island) with affinities to species found in Southern Australia, Tasmania and Antarctica.

Seven new species of Grania (Annelida: Clitellata: Enchytraeidae) from New Caledonia, South Pacific Ocean

Ingår i: Zootaxa. - 1175-5326. ; 1426, s. 27-50

Tidskriftsartikel (refereegranskat)abstract
- In meiofauna of the intertidal and subtidal zones (to 20 m depth) of New Caledonia seven species of the marine enchytraeid genus Grania were found, all of which were previously undescribed: G. novacaledonia sp.n., G. cinctura sp. n., G. galbina sp. n., G. curta sp. n., G. fustata sp. n., G. papillata sp. n. and G. fiscellata sp. n. On the basis of morphology, these new species seem to have a phylogenetic affinity to congeners in Australia and possibly Antarctica, although little is known about the enchytraeid fauna of the surrounding areas.
