Type material. Damaged male lectotype, cw 5.9 mm ( MNHN-B8733 ; Guinot 1969b: fig. 2); 1 male, 1 female, and 1 juvenile paralectotypes ( MCZ 9155 ) .

Type locality. Gulf of Mexico, north of Yucatán Channel , 23°13’N, 89°16’W, 151 m.

Material examined. Gulf of Mexico. North of Yucatán Channel , 23°13’N, 89°16’W, 151 m: damaged male lectotype, cw 5.9 mm ( MNHN-B8733 ) .

Diagnosis. See Remarks for Frevillea .

Remarks. In the original description, A. Milne-Edwards (1880b) did not designate a holotype specimen so all his material are technically syntypes. A male designated as “cotype” (MNHN-B8733) is damaged, with the chelipeds missing, only the right outer orbital angle remaining, and the ambulatory legs (except left P5, right P4) detached. A. Milne-Edwards & Bouvier (1923: 336), in a more complete treatment than the short description by A. Milne-Edwards (1880b: 15), referred to a male “type”, plus two adult females, one pre-adult male, and two pre-adult females; a male was illustrated and referred to as “type” (A. Milne-Edwards & Bouvier (1923: fig. 2, pl. 7, figs. 1, 2). The MNHN “cotype”, clearly an adult male, was referred to as the “ holotype ” by Rathbun (1918: 26), who listed it in her list of material examined. Although damaged, it does show the diagnostic characters of the species according to the description and the more complete treatment afterwards. As all of A. Milne-Edwards’ specimens are syntypes, the selection of a “type” by A. Milne-Edwards & Bouvier (1923) actually makes this specimen the lectotype of Frevillea barbata A. Milne-Edwards, 1880 . A female specimen referred to as a “co-type” and whose photograph was given by Guinot (1969b: fig. 2) could not be located in the MNHN. It must be part of the type material currently deposited in MCZ: one male, one female and one juvenile, plus many broken appendages (A. Baldinger, personal communication). These three specimens (MCZ 9155) therefore are paralectotypes.

Distribution. Western Atlantic from the Gulf of Mexico and Florida to Grenada, West Indies. Depth: subtidal to 300 m
