Regional Records: Medaeus noelensis - Forest & Guinot, 1961: 56, fig. 42-43, 44a-b, pl. 1, fig. 1 (Tahiti); 1962: 62 (Biogeography "Tahiti-Tuamotu"). - Monteforte, 1984: 171, annex 1, tab. a (Moorea, Tahiti); 1987: 9 (Moorea). - Paramedaeus noelensis - Serène, 1984: 90, fig. 51, pl. 12f (Syn.). - Guinot, 1985: 451 (List). - Poupin, 1996a: 41 (Checklist). - Danielea noelensis - Ng & Clark, 2003: 142, fig. 1c, 4a-e (new generic comb.). - AAMP, Marquesas, 2012, Leg 2, coll. Evans, sample 0336, St 19, Ua Huka, 20 m; Leg 3, St. MQ21-R, Ua Pou, 6-10 m, coll. Starmer et al., sample LC276, LC288, St. MQ24-GR-R, Ua Pou, 6-12 m, coll. Starmer et al., sample LC309, LC312, LC315. In the field Marquesan specimens have been first identified to Jacforus cavatus, a species very similar to Medaeus noelensis; they are here attributed to D. noelensis based on careful examination of photographs and photo & characters cited by Ng & Clark (2003), including carapace with weak grooves and ridges (higher, deeper in J. cavatus), postero-lateral margin of carapace almost straight (strongly concave in J. cavatus), and suture between sternite 2 and 3 still distinct (thoracic sternites 1-3, completely fused in J. cavatus).
