Paracycloppina sacklerae Boxshall & Jaume, 2012 (F,M) | |
| | | | | | | Ref.: | | | Boxshall & Jaume, 2012 (p.37, Descr. F,M, figs.F,M) |  Issued from : G.A. Boxshall & D. Jaume in Zootaxa, 2012, 3150. [p.39, Fig.1]. Female (from 5°11.052'S, 122°35159'E): A: habitus ovigerous (dorsal); B, urosome (Ventral; with caudal seta omitted); C, A1. Scale bars: 100 mm (A); 50 µm (B, C). Nota: 1st pedigerous somite free, but partly concealed by posterior extension of dorsal cephalic shield. Epimeral angles of free 2nd to 4th pedigerous somites rounded. Rostrum rounded, well developed. Nauplius eye not observed. Ratio of prosome to urosome length (including caudal rami) about 1.5:1. Urosome 5-segmented, comprising 5th pedigerous somite, genital double-somite (formed by fusion of genital and 1st abdominal somites, and 3 free abdominal somites. Genital apparatus comprising paired copulatory pores located within dorsolateral gonopores: seminal receptacles paired. Egg sacs paired, with 7 to 9 eggs. Caudal rami about 1.3 times longer than wide and bearing 6 caudal setae (seta I absent). A1 17-segmented

All scale bars = 50 µm. Nota: Labrum ovoid, with entire posterior margin; surface ornamentation of spinules on raised anterior zone. Mandible comprising coxa with well developed gnathobase bearing numerous blades along oblique margin. Endopod: 2-segmented with 3 + 5 setae. Exopod: 4-segmented bearing 5 sparsely plumose setae. Mx1 with large praecoxal arthrite bearing 8 marginal setal elements; coxal endite bearing single seta; coxal epipodite represented by long plumose seta; basis produced into 2 endites medially bearing 3 (proximal) and 2 (distal) spinulose setae; endopod comprising single expressed segment bearing 1, 1, 5 spinulose setae; exopod 1-segmented with 4 long plumose setae. Mx2: well developed, 5-segmented; praecoxa and coxa incompletely separated, bearing 4 inner margin endites, armed with 3, 1, 3, 2 spinulose setae (from proximal to distal); basis bearing powerful claw-like element and spinulose seta, ornamented with spinule rows; endopod 3-segmented, bearing 4, 1, 3 setal elements (from proximal to distal). Mxp: smaller than Mx2; 4-segmented; 1st segment (syncoxa) produced into 2 endites, proximal endite with 3 spinulose setae, distal endite armed with 2 setae, ornamented with row of spinules; 2nd segment (basis) with 2 spinulose setae and row of spinules; endopod 2-segmented, 1st endopodal segment with 2 unequal spinulose setae and 2nd endopodal segment with 4 spinulose setae.

Nota: Ratio of prosome to urosome length (including caudal rami) about 1.7:1. Epimeral angles of free 3rd pedigerous somites slightly produced. Urosome 6-segmented, comprising 5th pedigerous somite, genital somite and 4 free abdominal somites. Genital somite bearing paired genital openings ventrally.
