tly elongated segmlents; the long setae

Issued from : G.A. Boxshall & S.H. Halsey in An Introduction to Copepod Diversity. The Ray Society, 2004, No 166, Part. I. [p.202].
Armature formula of swimming legs P1 to P4. Outer spines on all exopodal segments of legs 2 to 4 fused to segment; outer spines on 3rd exopodal segment of leg 1 distinct at base.

Nota : P5 female comprising broad transverse plate formed by fusion of coxae and intercoxal sclerite. Each leg 3-segmented and uniramous ; comprising unarmed basis and 2-segmented exopod. 1st exopodal segment unarmed, 2nd tapering distally, slightly curved and claw-like ; outer margin strongly serrated on right side only.
- Male P5 asymmetrical ; intercoxal sclerite and protopodal segments fused to form robust trnsverse plate ; right leg with muscular basal pedestal carrying curved, claw-like unsegmented exopod distally and 3 processes on inner margin, one of which probably representing endopod. Left leg uniramous, lobate, indistinctly subdivided into robust, muscular proximal part and rounded distal part armed with 1 to 3 setae.
- Eggs released into water.

Remark: Apparently there is a mistake in the formula on P1: the seta is on inner of coxa and not on inner of basis.

Issued from : J.M. Bradford-Grieve in NIWA Biodiversity Memoir, 111, 1999. [p.211].
Setal formula of swimming legs P1 to P4.
- P5 uniramous, 3-segmented, and slightly asymmetrical in female.
- Left P5 male uniramous and right leg biramous, with both strongly modified.

Note on the distal inner part of basipod 1 (= coxa) the presence of one seta.

Remarques sur les dimensions et le sex-ratio:

The mean female size is 1.5 mm (1.6-1.4 mm), and the mean male size is 1.55 mm (1.5-1.6 mm)

Issued from : G.A. Boxshall & S.H. Halsey in The Ray Society, , 2004, N° 166.[p.203, Fig.51, C, D].
Sulcanus conflictus Female: C, A2; D, Mx1.

Nota: A2 uniramous; with no trace of exopod; 3-segmented, proximal segment (coxa) very short, unarmed; middle segment (allobasis) extremely elongated and armed with single seta (basal in origin) near midlength, distal segment (fused 2nd and 3rd endopodal segment) slender, not bilobed, with 6 long setae apically.
Mx1 reduced, 2-segmented; 1st segment armed with 11 elements along inner margin (possibly representing praecoxal arthrite); 2nd segment small, bearing 3 elements distally.
