Espèce Pleuromamma xiphias - Planche 20 de figures morphologiquesissued from : T.N. Weatherby, K.K. Wong & P.H. Lenz in J. Crustacean Biol., 1994, 14 (4). [p.672, Fig.1].
Line drawing of P. xiphias and right A1.
a, dorsal view of female showing relative length and normal position of antenna as seen in live animals; b, dorsal view of distal segment (XXIII to XXVII-XXVIII) and setae of first antenna of male, showing normal position of setae as seen in live animals.
Segment nomenclature follows Huys & Boxshall (1991).
Numbering of setae used throughout this text: c, highter magnification drawing of (b) showing two most distal segments.
The morphological results indicate the presence of 9 identifiable setae on the distal tip of A1; these include 5 dually innervated and 2 singly innervated mechanoreceptive setae.

The setae of the distal tip as a single sensory element reflect in physiological and behavorial specialization. Seta number 1 is the only long posteriorly pointing seta.
Seta number 2 clearly has an associated function, being closely apposed to number 1 and, secondarily shortened (indicating that its original length has become superfluous).
Seta number 3 is unlike any other seta in its remarkable flattened whiplike shape, the function of which is still obscure.
Seta 4 is the only chemosensilla within 0.200 mm of the tip, and we have as yet no information as to its chemical sensitivity.
Seta 5 is the only pure mechanosensory seta of a length which seems to be a part of the sequence of declining lengths running out the antennular shaft and is one of only three singly innervated setae (numbers 6 and 7 being the other two).
Seta number 6 appears vestigial and is probably completely within the boundary layer for most hydrodynamic stimuli.
Seta 7 appears to be only bimodal mechano-chemosensory seta on the tip.
Seta number 8 is the second longest seta, the longest anteriorly pointing one on the antenna and the only one which appears to be controlled by a discrete muscle.
Seta number 9 is the only \\\\\\\"feathered\\\\\\\" seta on the tip, sharing the feathered attribute with only two other setae in the distal region (segments XXV and XXIV), which may suit them well for monitoring direction of water flow.

Basic structure of mechanoreceptors in distal tip of A1.
a, dorsal view of distal subsegments with schematic drawing of longitudinal section of sensory and scolopale cell structures for seta number 8. Bipolar sensory cell bodies (scb) are located in segment XXVI, extending their proximal dendites (pd) distally. A peridentritic accessory cell containing scolopale material (sc) forms tube, enclosing distal dendrite(s) (dd) in liquor-filled cavity. Scolopale is elaborated from ciliary (basal body, bb) region of dendrite nearly to point at which seta segments antennal shaft. Bands of microtubules (mtb) appear at intervals, anchoring scolopale cell to cuticle. Only one distal dendrite shown for clarity.
Dashed lines labeled 6a and 6b correspond to antennal cross sections shown in Fig.6. b-d, cross sections through distal dendrites of mechanoreceptive sensory structures. Location of these cross sections shown by corresponding letter on left of antennular shaft in a.
magnifications of micrographs and expanded views as shown in (d).

b, pair of distal dendrites (dd) containing arrays of microtubules having both electron-dense and electron-lucent centers. Pair of dendrites loosely wrapped by thin processes of 2 or 3 accessory cells. Expanded view shows magnification of microtubules ;

c, distal dendrites within scolopale tube (sc) show proliferation of microtubules with electron-dense cores. Microtubules arise in rows from 9 electon-dense crescents in each dendrite. Expanded view shows magnification of crescents and microtubules.
d, ciliary region of sensory structure, showing pair of dendrites running through liquor cavity (lc), enclosed by thin scolopale tube. Left dendrite sectioned at level of basal body ; other just distal to its basal body, showing 9 + 0 circlet of microtubules with electron-dense centers in distal dendrite (see expanded view). Desmosomes formed between scolopale cell and attachment cell (*) mark sites of attachment of bands of microtubules which extend ti cuticle.

Nota: The receptor organs are characterized by well)developed scolopale tubes and large numbers of microtubules within the dendrites. The scolopale, which acts as a supporting structure, forms a complete tube around the liquor cavity and dendrites.

Distribution of identified sensory setae on A1 of P. xiphias female.

Nota: Table 1 shows a segmental account of all setal types on A1 females: of the 80 identified setae on A1, 60% are mixed-modality, possessing a distal pore and innervated by both mechano- and putative chemosensory neurons.
Aesthetasc-like chemosensory setae account for 29% of the total. Pure mechanosensory setae showing no evidence of chemosensory dendrites within the setae and lacking a distal pore, account for 11% of the setae. The latter are primarily found distally and they include hree posteriorly-pointing feathered setae.

Frequencies of nonsingleton mtCOI haplotypes in population samples of P. xiphias.
Haplotypes are labeled by color, as sampling in the North Atlantic, Pacific and Indian Ocean.
Singleton haplotypes are pooled and labeled in green, black and red for Clades 2, 3 and 4 respectively. White indicates the frequency of H11. Circles indicate population structure as infered from popûlation graph, principal coordinate, and Barrier (see text).

Nota: The species showed high levels of genetic differentiation among samples throughout its global biogeographic range, both within and among ocean basins. Limited dispersal among distinct pelagic provinces seems to have played a major role in population differentiation in this species, with strong genetic breaks observed across known oceanographic fronts or current systems in all three ocean basins.
The Indo-West Pacific (IWP) holds a highly distinct genetic population of this species that was sampled in both the western and eastern Indian Oceans. This suggests that the IWP does not act as a strong barrier to gene flow between basins, despite the relatively shallow water depth (<200 m) and vertically extensive (>400 m) diel migration. A pattern of isolation by distance was observed in the Indian Ocean with genetic differentiation among samples down to spatial scales of ± 800 km, indicating that realized dispersal in P. xiphias occurs over much smaller spatial scales than in previously reported oceanic holoplankton. Given its highly regionalized population genetic structure, P. xiphias may have some capacity to adapt to local oceanographic conditions, and it should not be assumed that populations of this species in distinct pelagic biomes will respond in the same way to shared physical or climatic forcing.

Distribution of prosome lengths (mm) for adult females (A) and males (B) of P. xiphias from genetic clades 3 and 4.
Mean body size in clade 4 is signuficantly smaller in both cases (t-test, P <0.001).

Nota: The author interprets the differences in prosome length among mt clades as being ptrimarily environmental in origin, and does not consider these results to be sufficiently strong evidence for distinct species-level status between clades 3 and 4 animals. Comparisons of animals from clades 3 and 4 collected in the same plankton tow, and which presumably experienced the same sea-water temperature during development, show a similar, but non significant, trend toward smaller body size in clade-4 animals (females only).

The mean female size is 4.530 mm (n = 41; SD = 0.6423), and the mean male size is 4.685 mm (n = 30; SD = 0.7786). The size ratio (male : female) is 1.004 (n = 15; SD = 0.0776).
Rem.: épi (rare), méso-bathypélagique.
Sampling depth (Antarct., sub-Antarct.) : 0-50-750 m. Les différences de taille observées au NW de l’Indien (Sewell, 1947) résulteraient des positions bathymétriques des populations, donc de l’origine des masses d’eau (eau intermédiaire tropicale et eau intermédiaire sud polaire).
