HISTORY. — Frevillea rosaea View in CoL was described from Blake ’s station 232 off St. Vincent, Lesser Antilles, from a depth of 88 fathoms (161 m) (A. Milne-Edwards, 1880: 15). He provided measurements for one female, 20.0 × 15.0 mm, but no type was indicated. For the species, Rathbun (1918: 27) stated: “type-locality, St. Vincent, 88, correctly 87, fathoms, station 232, Blake; holotype in Paris Mus.” and although she did not examine the specimen, her action constitutes the first valid designation of a name-bearing specimen or lectotype for the species. Alphonse Milne-Edwards & Bouvier (1923: 337) later commented that they had one type ovigerous female (has to be the one with the measurements 20.0 × 15.0 mm) and one juvenile. They figured the dorsal features, including the carapace for the type female (A. Milne-Edwards & Bouvier 1923: pl. 6, fig. 1) ( Fig. 3A). In addition, they wrote: “A part quelques différences très légères, tous les autres caractères sont identiques à ceux de cette dernière espèce, du moins dans le type chargé d’oeufs et dans le très jeune exemplaire qui m’ont été soumis.” [Apart from a few very slight differences, all the other characters are identical to those of the latter species, at least in the egg-bearing type and in the very young specimen passed to me.] (A. Milne-Edwards & Bouvier 1923: 337). These comments also constitute a name-bearing or lectotype designation, even if done after Rathbun (1918). Both Rathbun (1918) and A. Milne-Edwards & Bouvier (1923) apparently selected the same specimen to be the lectotype.

Chace (1940: 47) subsequently recorded the species from Cuba. Castro & Ng (2010: 56) listed one female “ lectotype ” (22.7 × 15.7 mm), one “ paralectotype ” male (16.3 × 10.1 mm) and one pre-adult female “ paralectotype ” (7.9 × 5.0 mm) (MNHN-B10152) for the species.

During the examination of material by the first author in May 2023, in the MNHN bottle labelled as “ Frevillea rosaea ” (MNHN-B10152), he found three specimens: a male (16.5 × 10.0 mm, without pleon and gonopods), a female (22.7 × 15.7 mm), and a juvenile female (7.9 × 5.0 mm) ( Figs 1 View FIG F-H; 2A, B, E, F). The adult female (22.7 × 15.7 mm) ( Figs 1G View FIG ; 2E View FIG ) is labelled as the “ lectotype ” of the species, with the other two “ paralectotypes.”. In the card catalogues in MNHN, three specimens are listed from St. Vincent, of which one juvenile is listed as the cotype (MP B10152). The locality labels in the bottle match those given by A. Milne-Edwards (1880), but there are no original labels from the Blake cruise. As discussed earlier under F. barbata , we are certain that these three specimens do not belong to F. rosaea but to F. barbata instead. The material in MCZ consists of only one ovigerous female specimen (22.1 × 15.4 mm) (MCZ-IZ-CRU-9167) ( Fig. 3 A-D) and is labelled as a “ syntype ” in the database.

TYPE MATERIAL. — On the basis of the published information, the 20.0 × 15.0 mm female reported by A. Milne-Edwards (1880) is the lectotype of F. rosaea . This specimen is clearly the MCZ ovigerous female specimen measuring 22.1 × 15.4 mm (MCZ-IZ-CRU-9167) ( Fig. 3 A-D). The discrepancies in measurements are minor and can easily be accounted for by differences in how the measurements were made. Morphologically, it agrees very well with the original figures in A. Milne-Edwards & Bouvier (1923: pl. 6 fig. 1). The juvenile specimen reported by A. Milne-Edwards & Bouvier (1923) should be regarded as a paralectotype.

MATERIAL EXAMINED. — Lectotype (by inference of holotype by Rathbun 1918: 27, as Goneplax rosaea ; A. Milne-Edwards & Bouvier 1923: 337 as F. rosaea ). Saint Vincent and the Grenadines • ovigerous ♀ (22.1 × 15.4 mm); station 232; off St. Vincent; 88 fathoms (= 161 m); 13°06’45”N, 61°06’55”W; coll. USCGS; George S. Blake cruise; 21.II.1879; MCZ-IZ-CRU-9167.

Paralectotype. Saint Vincent and the Grenadines • 1 juvenile ♂ (7.8 × 5.9 mm); same data as lectotype; MNHN-IU-2014-19822 (= MNHN-B10152) .

GEOGRAPHICAL DISTRIBUTION. — Western Atlantic region: Cuba and St. Vincent.
