CYCLASPIS RICHERI View in CoL SP. NOV. ( FIGS 3–5 View Figure 3 View Figure 4 View Figure 5 )
Type material: Holotype: adult female dissected in two slides, New Caledonia, BIOCAL, stn DW44, 22°47.3′S, 167°14.3′E, 440–450 m, 30.viii.1985 (MNHN-Cu1074) GoogleMaps . Paratypes: same station as holotype, 1 adult female, 15 preadult females, 13 preadult males, 2 juveniles (MNHN-Cu1075); stn DW46, 22°53.05′S, 167°17.08′E, 570–610 m, 30.viii.1985, 3 preadult males (MNHN-Cu1076); stn DW51, 23°05.27′S, 167°44.95′E, 700– 680 m, 31.viii.1985, 1 preadult male, 5 preadult females (MNHN-Cu1077), stn CP75, 22°18.65′S, 167°23.30′E, 825–860 m, 5.ix.1985, 2 mancas (MNHN-Cu1078); stn DW77, 22°15.32′S, 167°15.40′E, 440 m, 5.ix.1985, 3 preadult males, 4 preadult females (MNHN-Cu1079).
Diagnosis: Carapace globose and smooth, finely reticulate at high magnification. Pseudorostral lobes not meeting in front of the eyelobe. Uropod peduncle shorter than half length of pleonite 6; endopod nearly twice as long as peduncle; exopod of similar length as endopod, inner margin smooth without setae.
Description: Adult female 8.73 mm total length. Carapace ( Fig. 3 View Figure 3 ) slightly shorter than one-third total length, globose, finely reticulate at high magnification ( Fig. 4B View Figure 4 ); produced backwards dorsally hiding pereonite 2 in dorsal view (in preadult especimens it is more produced hiding part of pereonite 3; see Fig. 4A View Figure 4 ). Pseudorostral lobes not meeting in front of eyelobe. Eyelobe without lenses. Antennal notch deep, anterolateral angle acute.
Antennule ( Fig. 3B View Figure 3 ), peduncle article 1 longer than combined length of articles 2 and 3; article 3 as long as article 2; main flagellum 2-articulate, with two aesthetascs, accessory flagellum rudimentary. Left mandible ( Fig. 3C View Figure 3 ) with four teeth on the pars incisiva, 17 setae between pars incisiva and pars molaris (18 setae on right mandible). Maxillule ( Fig. 3D View Figure 3 ) palp with two unequal filaments, inner endite with four setae, three simple and one trifid. Maxilla ( Fig. 3E View Figure 3 ), endites with simple and serrulate setae.
Maxilliped 1 ( Fig. 3F View Figure 3 ), basis with six setae on inner margin, distally produced reaching carpus; carpus with six bi-dentate flattened setae on the inner margin and a long pappose seta on distal outer corner. Maxilliped 2 ( Fig. 3G View Figure 3 ) basis longer than rest of appendage, with two plumose setae on inner distal corner; carpus longer than merus, with seven plumose setae on inner margin; propodus with a long pappose seta on proximal half, a simple seta on distal outer corner and three simple setae on distal inner corner. Maxilliped 3 ( Fig. 5A View Figure 5 ), basis expanded distally over mero-carpal articulation, with a row of plumose setae on inner margin of projection; merus produced distally not reaching the carpo-propodial articulation with a plumose seta on its tip. Pereopod 1 ( Fig. 5B View Figure 5 ), basis shorter than rest of appendage; ischium and merus short; carpus shorter than propodus; dactylus shorter than carpus and half length of propodus. Pereopod 2 ( Fig. 5C View Figure 5 ), basis longer than rest of appendage; ischium short; merus three times as long as ischium, with a plumose seta distally; carpus shorter than merus, with two cuspidate setae on distal corner; dactylus nearly twice as long as propodus, with three cuspidate setae terminally. Pereopod 3 ( Fig. 5D View Figure 5 ), basis longer than rest of appendage, with simple seta on distal margin; merus three times as long as ischium and as long as carpus; propodus with a long simple seta on distal corner. Pereopod 4 ( Fig. 5E View Figure 5 ), basis as long as rest of appendage; merus nearly as long as carpus; carpus and propodus with two and one long simple setae on distal corner, respectively. Pereopod 5 ( Fig. 5E View Figure 5 ), basis shorter than rest of
DEEP-SEA PACIFIC BODOTRIIDAE 231
appendage; merus nearly as long as carpus; carpus and propodus with two and one long simple setae on distal corner, respectively.
Uropod peduncle ( Figs 4C View Figure 4 , 5G View Figure 5 ) shorter than half length of pleonite 6; endopod nearly twice as long as peduncle, inner margin crenulate; exopod of similar length than endopod, inner margin without setae.
Etymology: This species is named after Bertrand Richer de Forges ( IRD, New Caledonia) in recognition of his efforts in collecting deep-sea fauna in the Indo- West Pacific.
Remarks: Resembles C. globosa Hale, 1944 but differs from it by the lack of lenses in the eyelobe, the lack of plumose setae on the basis of pereopods, the shortness of uropod peduncle and the rami that lack plumose setae. C. pinguis Hale, 1944 also has affinities with C. richeri , but the peduncle of the uropod is nearly as long as the telsonic somite and the carapace does not hide the second pereonite in dorsal view.
