Iboyella cubensis Boxshall & Jaume, 2003 (F) | |
| | | | | | | Ref.: | | | Boxshall & Jaume, 2003 (p.86, figs.F) |  issued from : G.A. Boxshall & D. Jaume in Org. Divers. Evol., 2003, 3.[p.87, Fig.1]. Female (from Cuba): A, habitus (dorsal); B, genital double-somite; C, detail of 3rd abdominal somite, anal somite and caudal rami (dorsal); D, A2; E, Mx1. Scale bars 0.100 mm, unless otherwise stated. Nota: Length ratio of prosome to urosome 2.3:1. Nauplius eye absent. Urosome 4-segmented. Genital operculum located medially; paired, crescent-shaped gonoporal slits visible internally. A2 with exopod longer than endopod; coxa and basis separate; exopod 9-segmented but proximal segments not completely defined on all surfaces; Mx1 with well-developed praecoxal arthrite bearing 11 marginal spines; coxal epipodite with row of 6 long setae; coxal endite with 3 unequal setae; outer basal seta lacking; proximal basal endite, elongate, with 2 long and 2 short setae; distal basal endite represented by single seta; exopod unsegmented, long and slender, armed with 7 sparsely plumose setae; endopod elongate, unsegmented, setal formula 1 + 1+ 4. Anal somite extremely short and almost completely concealed by telescoping within the 3rd abdominal somite. Caudal rami symmetrical, about 2.8 times longer than wide, with patch of setules distally on inner margin; caudal seta VI asymmetrical, with setular tuft present prosimally on inner margin of seta on left ramus; seta I absent.

 issued from : G.A. Boxshall & D. Jaume in Org. Divers. Evol., 2003, 3.[p.88, Fig.2]. Female: A, proximal part of A1, segments 1 ( I) to 15 ( XVIII); B, distal part of A1, segments 16 ( XIX) to tip; C, Mxp (drawn with free endopodal segments separated for clarity). Scale bars 0.100 mm. Nota: A1 23-segmented, extending beyond posterior margin of cephalosome. Mxp 7-segmented; syncoxal endites developed, setal formula 1, 2, 4, 4; basis about as long as syncoxa, with 3 unequal setae, 1 brush-like, plus margnal row of spinules proximally on inner margin; 1st endopodal segment partially incorporated into basis, bearing 2 unequal setae; free endopod 5-segmented, setal formula 4, 4, 3, 3 +1, 3; apical segment minute, offset on distal margin of subapical segment.

 issued from : G.A. Boxshall & D. Jaume in Org. Divers. Evol., 2003, 3.[p.90, Fig.4]. Female: A, rostrum (anteroventral view); B, Md; C, P4; D, P5. Scale bars 0.100 mm. Nota: Rostrum weakly developed, forming broad shallow plate with large rostral filaments located subdistally at each outer corner. Md strongly developed, with coxal gnathobase cutting edge bearing bicuspidate ventralmost tooth, row of 5 multicuspidate subsimilar teeth, plus pinnate dorsalmost seta, row of short spinules located subdistally, close to tooth row; palp biramous, with large basis bearing single minute seta about midway along medial margin; endopod with proximal segment incorporated into basis, bearing single tiny seta, distal segment with 3 unequal setae; exopod 5-segmented, setal formula 1, 1, 1, 1, 2.
