Abstract(s)
Five marine arthrotardigrade species are recorded from Moorea, Society Islands, French Polynesia. Four were collected
from coral sand; two, Dipodarctus anaholiensis Pollock, 1995 and Florarctus kwoni Chang & Rho, 1997, are new records
for the region, and two, Halechiniscus perfectus Schulz, 1955 and Styraconyx kristenseni kristenseni Renaud-Mornant,
1981, have been previously reported. The fifth, a new species Styraconyx turbinarium sp. nov., is described and was collected
from the drifting brown alga Turbinaria ornata. The new species is characterized by the presence of peduncles on
all digits, an elongate primary clava, and the lateral cirrus A arising from a common pedestal and enveloped by a common
membrane extending almost to the claval tip. The new species differs from the most similar species, Styraconyx tyrrhenus
D’Addabbo Gallo, Morone De Lucia & de Zio Grimaldi, 1989, by having longer and differently shaped primary clavae
which are elongated in the new species and club-shaped in S. tyrrhenus. By having a dorsal cuticle that is coarsely punctated
but without folds or other ornamentations, the new species can be easily distinguished from S. craticulus (Pollock,
1983), a species with similar primary clavae, but with cuticular dorsal folds ornamented with a grid-like pattern.
