Coifmanniella parageia (Brattegard, 1970)

( Figs. 3 I–J, 4F, 5F, 8G)

Bowmaniella parageia Brattegard, 1970a: 17 , fig. 4, tables 7–8.

Bowmaniella sewelli Brattegard, 1970a: 14 , fig. 3, tables 7–8, 1970b: 122, 1974a: 51, 1974b: 92, 1975: 110; Modlin, 1984: 280 (new synonymy).

Material examined. 40 ♂, AMNH 13609 (paratypes— Bowmaniella sewelli ), Turtle Rocks, Bahamas, 9 May 1967, coll. T. Brattegard, night plankton.— 8 ♂, AMNH 13611 (paratypes— Bowmaniella parageia ), Turtle Rocks, Bahamas, 9 May 1967, coll. T. Brattegard, night plankton.

Diagnosis. Posterodorsal margin of carapace reflected anterodorsally ( Fig. 8 G). Abdominal somite 5 lacking articulated posterodorsal process. Uropodal endopod with 7–16 small spiniform setae distal to statocyst ( Fig. 5 F). Telson with lateral margins armed with rows of 12–25 spiniform setae, 6–8 larger interrupted by smaller ones; telsonic cleft shallow, less than 1/5 length of telson ( Fig. 4 F).

Type locality. Near Long Island, Bahamas (22°55'10"N, 74°54'35"W).

Distribution. Gulf of Mexico ( Modlin 1984), Bahamas, Florida Keys, southern and western Caribbean ( Brattegard 1970 a, b; 1974 a, b).

Remarks. Coifmanniella parageia (Brattegard, 1970) , which is the terminal form of C. sewelli Brattegard, 1970 , is designated as the senior synonym since it represents the ultimate male stage for the species. It is interesting to note that most of the paratypes chosen by Brattegard (Brattegard, 1970) for both male forms of C. parageia and C. sewelli were taken from the same sample in the Bahamas.
