HOLOTYPE (by original designation). — MNHN-B26474, Mariana Islands, Guam, Piti Reef , 1 m, among rocks, VIII.1993, ♂ 9.7 × 11.9 mm, right P3 and left P4 missing.

Dynomene latreillii Eydoux & Souleyet, 1842 (Fig. 15A)

Dynomene latreillii Eydoux & Souleyet, 1842: 239 , pl. 3, figs 3-5 ( Dynomena latreillii ).

CURRENT STATUS. — Dynomene hispida Guérin-Méneville, 1832 .

HOLOTYPE (by monotypy). — MNHN-B23 (cited as B 235 in McLay 1999), Hawaii, 1836, specimen stuck on a piece of elder, sex undeterminable, abdomen missing, 5.5 × 6.5 mm (6.0 mm long indicated by Eydoux & Souleyet [1842: 240], 6.0 × 7.9 mm indicated in McLay [1999: 475]), McLay 1996 det. Dynomene hispida , dry, left P1 and pair of P5 missing. — Original label: “ Dynomene hispida (Latr.) , D. latreillei (Eydoux et Souleyet) , Voyage de la Bonite, Îles Sandwich”.

REMARKS

The text of Eydoux & Souleyet (1842: 240) unambiguously reveals that the taxon had been based on a single individual, consequently the term “ holotype ” was correctly used by McLay (1999: 475), followed by Davie (2002: 168).

Dynomene praedator A. Milne-Edwards, 1879 (Fig. 15B)

Dynomene praedator A. Milne-Edwards, 1879: 8 , pl. 14, figs 20-26.

LECTOTYPE (by present designation). — MNHN-B3991, selected among six specimens labelled “ Dynomene praedator A. M. Edw. , TYPES! Ann. sc. nat. (6) T. VII, pl. XII, fig. 20-26, 1878, Nouvelle Calédonie (1875), Coll. [Collection] A. Milne Edwards, 1903”, undeterminable sex, 10.0. × 12.5 mm, dry, still stuck on the original cardboard.

PARALECTOTYPES. — MNHN-B30160, same data as lectotype, 5 specimens, dry, still stuck on their original cardboard, so that the sex cannot be recognized, except for one female of the lot turned ventrally.

REMARKS

A. Milne-Edwards (1879: 9) did not designate a type specimen when describing the species based on male (10.0. × 13.0 mm) and female (8.0 × 10.0 mm) from New Caledonia and Samoa. McLay (1999:482, 486) argued that, as A. Milne-Edwards (1879: pl. 14, figs 20-26) figured the male and its measurements were presented first, then the male should be regarded as the holotype.He ( McLay 1999: 486) considered that this male collected by Balansa from the intertidal, New Caledonia, 1873 “probably no longer exists” because the figures in plate 14 (A. Milne-Edwards 1879) showed the male (10.0 × 13.0 mm) with a dismembered thorax ( McLay 1999: 486). However, McLay (1999: 486) suggested “there is a paratype female (10.2 × 8.1 mm) from the same collection, and held at the Muséum national d’Histoire naturelle, Paris, registration number MNHN-B7029” (in alcohol). According to McLay (1999: 486), his own description of D. praedator was based on this female MNHN-B7029 which “has the label Dynomene praedator A. Milne Edwards Nouvelle Calédonie. Coll. A. Milne Edwards, 1903 ”. McLay continued: “These dimensions are very close to those given by A. Milne Edwards (1879) for the female specimen that he mentions so it is likely that this is the female paratype ” (see also Davie 2002: 169).

During the preparation of this catalogue, a box with six specimens, still glued on their original cardboard and labelled “ Dynomene praedator A. M. Edw. , TYPES” (see above), was discovered in the MNHN collection (MNHN-B3991). C. L. McLay did not see these specimens during his stay at the MNHN. The largest specimen is probably the individual with dimensions similar to the male figured by A. Milne- Edwards (1879: pl. 14, figs 20-26). This specimen, which corresponds to the holotype mentioned by McLay (1999), is here designated as the lectotype for Dynomene praedator and keeps the ancient registration number MNHN-B3991. Among the other five dry specimens of the same lot there is female turned ventrally whose width is 10.0 mm, this is probably the female mentioned by A. Milne-Edwards (1879: 9). All these five specimens become paralectotypes and are now registered MNHN-B30160.

The female forming lot MNHN-B7029 (in alcohol), 8.1 × 10.2 mm, from New Caledonia but not labelled as a type and designated as paratype by McLay (1999: 482, 486), is not a paralectotype.

Dynomene ursula Stimpson, 1860 (Fig. 15C)

Dynomene ursula Stimpson, 1860: 239 .

CURRENT STATUS. — Hirsutodynomene ursula (Stimpson, 1860) .

LECTOTYPE. — MNHN B3992, Mexico, Baja California, Cabo San Lucas , ♀ 11.0 × 14.5 mm, dry. — Label: “ Dynomene ursula Stimpson , Saint Lucas, Coll. [Collection] A. M. Edwards 1903, probablement TYPE”.

REMARKS

According to Stimpson (1860: 176) the original material collected in North America was held by the Smithsonian Institution. His Dynomene ursula was represented by several male and female specimens, collected by M. J. Xantus at Cape St. Lucas. Rathbun (1937: 54) stated that the type of D. ursula was not extant. McLay(1999:511) wrote that the holotype was a male measuring 12.7× 15.2 mm,dimensions that are actually those of the female mentioned by Stimpson (0.5 × 0.6 inches). McLay added that a syntype was held by the Museum of Comparative Zoology,Harvard (MCZ 1378). The holotype designation by McLay constitutes a misuse of the Code ( ICZN 1999: Art. 74.6).The female MNHNB3992 is here designated as the lectotype of Dynomene ursula , and the MCZ 1378 specimen becomes a paralectotype.

HOLOTYPE (by original designation). — MNHN-B26602, New Caledonia, HALICAL 1, Alis , stn DW02, 18°54’S, 163°24’E, 352-397 m, 23.XI.1994, ♀ 24.0 × 23.2 mm, several legs detached.

Paradynomene diablo McLay & Ng, 2004 (Fig. 16B)

Paradynomene diablo McLay & Ng, 2004: 14 , figs 7B, 9, 14D.

HOLOTYPE (by original designation). — MNHN-B26610 (erroneously MNHN-B 26607 in McLay & Ng ), Indonesia, KARUBAR, Baruna Jaya 1, stn DW49, Tanimbar I., 8°00’S, 132°59’E, 206-210 m, 29.X.1991 (erroneously New Caledonia, Norfolk Ridge, BATHUS 3, Alis, stn

DW830, 23°20’S, 168°01’E, 361-365 m, 29.XI.1993, in McLay & Ng), ♂ 12.6 × 11.4 mm, P1 detached.

REMARKS

The specimen MNHN-B26607 was previously identified as P.tuberculata by McLay(1999).Considering the list of material identified as P. tuberculata ( McLay 1999: 543) , it appears that the holotype of Paradynomene diablo , a male 12.6 × 11.4 mm, was not collected in New Caledonia but corresponds to the male specimen, 12.5 × 11.2 mm, collected in Indonesia (KARUBAR, Baruna Jaya 1, stn DW49, Tanimbar I., 8°00’S, 132°59’E, 206-210 m, 29.X.1991, MNHN-B26610). A label in the tube indicates that this specimen was the one sent on loan to C. L. McLay. However, a sample from BATHUS 3, stn DW830 (MNHN-B26607), with a male 15.5 × 15 mm (cited as 15.8 × 14.7 mm in McLay 1999:543, as P.tuberculata ), contains an erroneously type label “ Paradynomene diablo Holotype ”. This specimen was not re-examined by McLay & Ng (2004) in their revision of Paradynomene , and its identification needs to be clarified.In conclusion, the holotype of P. diablo McLay & Ng, 2004 is a male 12.6 × 11.4 mm from Tanimbar I., Indonesia (see above), registered MNHN-B26610.
