Palpophria aestheta  Boxshall & Iliffe, 1987   (F)
Boxshall & Iliffe, 1987 (p.240, Descr.F, figs.F); Boxshall, 1989 (p.524); Boxshall & Halsey, 2004 (p.220: figs.F); Vives & Shmeleva, 2010 (p.139, figs.F, Rem.)
Species Palpophria aestheta - Plate 1 of morphological figuresissued from : G.A. Boxshall & T.M. Iliffe in Zool. J. Linn. Soc., 1987, 91. [p.241, Fig.10].
Female (from Lanzarote, Canary Islands): A, habitus (dorsal); B, urosome (ventral); C, A1 (dorsal); D, A2 (posterior).
Scale bars = 0.050 mm except for A (0.100 mm).

Nota: Prosome 5-segmented; no carapace-like extension present on maxilliped-bearing somite so 1st pedigerous somite completely exposed. Nauplius eye absent.Rosytum bilobed, ventrally directed and just visible in dorsal view. Urosome 5-segmented, with genital and 1st abdominal somites fused although a partial suture is present ventrally. Caudal rami about 1.4 times longer than wide; armed with a long inner seta on distal margin, a short distal seta, a lateral seta and a dorsal seta. A1 25-segmented; aesthetasc on ventral surface of segment VII, with a right angled bend. A2with unarmed coxa and basis; endopod 2-segmented; exopod 6-segmented. P5 reduced to a ventrally directed, conical lobe bearing 1 apical seta; legs connected by bar representing intercoxal sclerite. P6 represented by 1 seta on each of the plates closing off the genital openings.

Species Palpophria aestheta - Plate 2 of morphological figuresissued from : G.A. Boxshall & T.M. Iliffe in Zool. J. Linn. Soc., 1987, 91. [p.242, Fig.411.
Female : A, ventral view of oral area, showing labrum (la), rostrum (r), paragnath (pg), maxillulary arthrite (ar), mandibular gnathobase (gn) and mandibular palp (mp); B, distal margin of mandibular gnathobase (anterior); C, Mx1 (anterior); D, Mx2 (posterior); E, Mxp (posterior).
Scale bars = 0.050 mm except for B (0.025 mm).
Nota: Labrum a large lobe with a medially incised posterior margin. Md remarkable with the palp extremely long, reaching almost to posterior margin of prosome, and is capable of considerable rotation around its articulation with the coxa.

Female: A-D, P1 to P4 (anterior views).
Scale bars = 0.050 mm.

According to Boxshall & Iliffe (1987, p.245) the species is probably a raptorial predator. The Mx1, Mx2 and Mxp are adapted for grasping and manipulating prey; in particular, the long praecoxal arthrite and coxal endite of the maxillule are held in such a way as to be able to grip prey and hold it near to the mouth. This arrangement is similar to that found in some cyclopoids, and Mx1 may be used as in the predatory Macrocyclops albidus studied by Fryer (1957). The robust, spinous nature of the armature of the maxillae and maxillipeds also resembles that of M. albidus and the feeding mechanism as a whole is probably the same.
