Espèce Paralubbockia longipedia - Planche 1 de figures morphologiquesissued from : G.A. Boxshall in Brit. Mus. nat. Hist., Zool., 1977, 31 (3). [p.106, Fig.1].
Female (from 18°N, 25°W): a, habitus (dorsal); b, A2; c, A1 (ventral); d, Md (posterior); e, Mx1 (posterior); f, Mx2 (posterior); g, Mxp (anterior); h, anterior of urosome (ventral).
Nota: Prosome longer than urosome. Rostrum small and rounded. Relative lengths orosome somites and caudal rami 15:33:15:12:14:11. Caudal rami about 1.5 times longer than broad. A2 2-segmented. Mxp 4-segmented with a long claw-like distal segment; 2nd segment with a continuous row of spinules along inner margin and 2 naked setae; P5 a free segment with 2 naked apical setae and a lateral seta located on surface of somite near base. P6 probably represented by unarmed cuticularized plate located near genital aperture.

Espèce Paralubbockia longipedia - Planche 8 de figures morphologiquesissued from : G.A. Boxshall & R. Huys in Biol. Oceanogr., 1988/1989, 6. [p.167].

Roman numeral = spine; arabic numeral = seta.


Espèce Paralubbockia longipedia - Planche 9 de figures morphologiquesissued from : G.A. Boxshall & R. Huys in Biol. Oceanogr., 1988/1989, 6. [p.168, Fig.4].
Male: A, A1 (ventral); B, labrum (ventral view); C, P1 (anterior); D, P1 (detail of distal part of exopod segment 3).
Nota: Labrum: a small flattened plate, unarmed but with a large apical pore.


Espèce Paralubbockia longipedia - Planche 10 de figures morphologiquesissued from : G.A. Boxshall & R. Huys in Biol. Oceanogr., 1988/1989, 6. [p.170, Fig.6].
Female & Male: A, P2 (anterior); B, P4 (anterior); C, Md (of second female paratype showing variation in spinulation pattern.


Espèce Paralubbockia longipedia - Planche 11 de figures morphologiquesissued from : G.A. Boxshall & R. Huys in Biol. Oceanogr., 1988/1989, 6. [p.171, Fig.7].
Male: A, A2 (lateral); B, Md (anterior); C, Mx1 (ventral); D, Mx2 (possibly incomplete); E, Mxp (lateral).
Nota: Claw of Mxp apparently representing an endopodal segment plus terminal claw, with trace of suture between them; inner margin of incorporated endopodal segment bearing a row of spinules and an apical seta. The reduction in the Md and in the praecoxal endite of Mx1 suggests that the adult male is nonfeeding. This is quite a common strategy among planktonic \"poecilostomatoids\", also found in males of the sapphirinid genus Copilia for example. In both sexes the palp ot Mx1 is separated from the proximal segment by a complete structure. This is another unique plesiomorphy within the \"Poecilostomatoid\", since Mx1 is typically reduced to a bilobed orocess in \"Poecilostomatoids\".
