The Simodactylus Candèze, 1859, of French Polynesia (Coleoptera, Elateridae). While only two species of Simodactylus were known from French Polynesia, Simodactylus cinnamomeus (Boisduval, 1835) and Simodactylus perraulti Chassain, 2001, a third species has been collected on the island of Raiatea, in the Society Islands, Simodactylus delfini Fleutiaux, 1907. A key to the three Simodactylus species of French Polynesia is proposed as well as figures of the discriminating characters.

A Helorid wasp, Helorus ruficornis Förster, 1856, is reported for the first time on Tahiti (Society Islands), which is also the first record of both Proctotrupoidea and family Heloridae in French Polynesia. The potential hosts of Helorus ruficornis in French Polynesia are discussed.

A survey was carried out to identify the viruses infecting vanilla in French Polynesia and to assess their incidence. Virus identification was based on enzyme-linked immunosorbent assay (ELISA) and, for potyviruses, on the sequence of part of the coat protein and inoculation assays. Between 1998 and 1999, 3,610 vanilla plants from 49 plots in the Society Islands were indexed. Cymbidium mosaic virus (CymMV) was detected in 500 vines from 10 plots in the Leeward Islands. The data suggest that this virus has spread widely since its first detection in French Polynesia in 1986, most likely through the dissemination of symptomless infected cuttings. Viruses belonging to the Potyvirus genus were found in 674 plants from 27 plots in the four islands surveyed. Three distinct potyviruses have been identified: (i) Vanilla mosaic virus, (ii) Watermelon mosaic virus, and (iii) and a virus related to Bean common mosaic virus. The symptoms induced on Vanilla tahitensis by the three potyviruses can be differentiated from each other and from those due to CymMV. A significant proportion of the plants surveyed (97/476) were symptomatic but tested negative by ELISA for CymMV and the Potyvirus group. Odontoglossum ringspot virus was not detected in any sample tested.

Using Data

Small boat surveys were organized to study cetaceans of the Marquesas (9°S and 140°W) and the Society Islands (17°S and 150°W) in French Polynesia. Prospecting took place from 12–15 m sailboats, between 1996 and 2001 with systematic visual searching. Boats moved according to sea conditions, at a mean speed of 10 km/h. Effective effort of 4856 km in the Marquesas and 10,127 km in the Societies were logged. Relative abundance indices were processed for odontocetes using data obtained with Beaufort 4 or less. In the Marquesas, 153 on-effort sightings were obtained on 10 delphinids species including the spotted dolphin, spinner dolphin, bottlenose dolphin, melon-headed whale and rough-toothed dolphin. In the Societies, 153 sightings of 12 odontocetes included delphinids (spinner, rough-toothed and bottlenose dolphins, short-finned pilot and melon-headed whales, Fraser's dolphin, Risso's dolphin and pygmy killer whale) and two species of beaked whales, the sperm whale and dwarf sperm whale. Relative abundance indices were higher in the Marquesas than in the Societies both inshore (0.93 ind/km2 against 0.36 ind/km2) and offshore (0.28 ind/km2 against 0.14 ind/km2). Differences in remote-sensed primary production were equally important, the Marquesas waters featuring an annual average of 409 mgC.m−2 · day−1 and the Societies of only 171 mgC · m−2 · day−1. The presence of a narrow shelf around the Marquesas also accounted for differences in odontocete populations, in particular the delphinids.

AbstractThe emergence of DNA barcoding and metabarcoding opened new ways to study biological diversity, however, the completion of DNA barcode libraries is fundamental for such approaches to succeed. This dataset is a DNA barcode reference library (fragment of Cytochrome Oxydase I gene) for 2,190 specimens representing at least 540 species of shore fishes collected over 10 years at 154 sites across the four volcanic archipelagos of French Polynesia; the Austral, Gambier, Marquesas and Society Islands, a 5,000,000 km2area. At present, 65% of the known shore fish species of these archipelagoes possess a DNA barcode associated with preserved, photographed, tissue sampled and cataloged specimens, and extensive collection locality data. This dataset represents one of the most comprehensive DNA barcoding efforts for a vertebrate fauna to date. Considering the challenges associated with the conservation of coral reef fishes and the difficulties of accurately identifying species using morphological characters, this publicly available library is expected to be helpful for both authorities and academics in various fields.

New Host Records

Spirocamallanus monotaxis is redescribed from Monotaxis grandoculis (Lethrinidae) and reported from 10 other species of coral reef associated fishes from both the Society Islands and the Tuamotu Islands. This represents a new locality for S. monotaxis and 10 new host records. Spirocamallanus colei n.sp. is described from Acanthurus achilles (Acanthuridae) and from Acanthurus guttatus, Acanthurus lineatus, Acanthurus triostegus, and Zebrasoma scopas from both the Society Islands and the Tuamotu Islands. Spirocamallanus chaimha n.sp. is described from Ctenochaetus striatus and Acanthurus olivaceous (Acanthuridae) from Moorea in the Society Islands. The number of buccal capsule ridges in Spirocamallanus varies and minor differences have no taxonomic importance. Marine Spirocamallanus species appear to belong to a single clade characterized by 3 preanal papillae and 5 postanal papillae. This clade may be subdivided on the basis of the shape of the female tail. In French Polynesia, ecological factors as opposed to phylogenetic factors appear to determine host specificity for Spirocamallanus. A new system of reporting the positions of the caudal papillae, based on the position of the papillae relative to the length of the alae, is used.
