( Figs. 387 View FIGURE 387 , 388 View FIGURE 388 )
Typematerial. Holotype (intact ♀, MNHN-IU-2014- 21423 ) anddissectedparatype (♀, figured) from Botryllus planus (Van Name, 1902) (MNHN-IT-2008-1729 = MNHNS 1/ BOT.B/21), W. Îleta Cochons, Guadeloupe Stn 13, depth 5-10 m, Monniot coll., 23 December 1980.
Etymology. The name of the new species is derived from the Caribbean.
Descriptionoffemale. Body ( Fig. 387A View FIGURE 387 ) resembling that of C. magellanica sp. nov., but segmentation of prosome more obscure. Body length 2.05 mm. Cephalosome indistinctly defined from metasome. Urosome 4-segmented ( Fig. 387B View FIGURE 387 ), distinctly narrower and shorter than prosome; first urosomite (genital complex) notarticulated from prosome; genital apertures not discernible. Three free abdominal somites indistinctly articulated. Caudalramus ( Fig. 387C View FIGURE 387 ) small, lobate, about twiceaslongas wide (55×25 μm),fusiform, notarticulated from anal somite, ornamented with many setules: caudal setae absent.
Rostrum ( Fig. 387D, E View FIGURE 387 ) large, smooth, tapering in distal two-thirds towards rounded apex. Antennule ( Fig. 387E View FIGURE 387 ) lobate, unsegmented, shorter than rostrum, blunt tipped, sparsely ornamented with minute setules over distal surface; setae apparently absent. Antenna ( Fig. 387F View FIGURE 387 ) robust, 4-segmented; coxa, basis, and first endopodal segment unarmed, each much wider than long; distal endopodal segment about 1.4 times longerthan wide (45×33 μm): armedwith 4 smallsetae, 2 inserted into basal part of terminal claw; terminal claw strong, straight, aslongas segment.
Labrum convex posteriorly. Mandible ( Fig. 387G View FIGURE 387 ) with broad coxal gnathobase bearing 3 major teeth and several minute denticles on medial margin, and bluntly produced, spinulose proximal corner; 3 major teeth each bearing 3 or 4 spinules on proximal margin; distalmost tooth with 1 minute denticle at base of distal margin: palp consisting of obscurely defined exopod bearing 5 short, naked setae and basis-endopod complex bearing 3 small, naked setae, one originating from basis region and remaining 2 more distally. Maxillule ( Fig. 387H View FIGURE 387 ) bearing 8 setae on arthrite, 1 broad seta on coxal endite, 2 on epipodite; exopod and endopod fused with basis, bearing 4 setae each on exopodal region and endopodbasis complex; all setae pinnate. Maxilla ( Fig. 387I View FIGURE 387 ) 3- segmented; syncoxa bearing 2 endites, each tipped with 2 setae; basiswith 1 setaplusmassive clawbearing 2 rows of thick setules distally; endopod 1-segmented, rudimentary, tipped with 2 thin setae. Maxilliped ( Fig. 387J View FIGURE 387 ) lobate, armed with 4 unequal, naked setae (2 subdistal and 2 distal).
Legs 1–4 ( Fig. 388 View FIGURE 388 A-D) biramous; both rami fused with protopod in all legs. Leg 1 with protopod retaining trace of articulation and bearing inner distal setaon basis region. Exopods of legs 1–4 larger than endopods. Exopod of leg 1 incompletely 2-segmented, but endopod and both rami of other legs unsegmented, lobate. Minute setae present: 6, 10, 7, and 5 on exopods of legs 1–4, respectively, and 4, 4 (or 5), 6, and 3 (or 4) on endopods of legs 1–4, respectively. Legs 5 and 6 absent.
Male. Unknown.
Remarks. Campopera caribbensis sp. nov. differs from itstwo congeners in havingan unsegmentedantennule compared to the 2-segmented limb present in both C. michaelseni and C. magellanica sp. nov. In addition, the maxillary syncoxa has 2 endites in the new species in contrast to 3 endites in both of its congeners, and the maxillary endopod has only 2 setae, in contrast to 3 setaein C. michaelseni and 4 setaein C. magellanica sp. nov.
