Trefusialaimus idrisi Leduc 2013, sp. nov.
No full text<i>Trefusialaimus idrisi</i> sp. nov. <p>Figs 3-4; Table 1</p> <p>urn:lsid:zoobank.org:act: 56BD1B40-542A-4FE2-BB84-F8FC7C5C2667</p> Diagnosis and relationships <p> <i>Trefusialaimus idrisi</i> sp. nov. is characterised by relatively short body length, presence of numerous golden inclusions in the chords, cephalic setae 0.65-0.80 cbd long, spicules 2.3 abd long, 4 pairs of pericloacal papillae, and long, gradually tapering tail.</p> <p> Until now, only two <i>Trefusialaimus</i> had been described, viz., <i>T. magnus</i> (Filipjev, 1946) and <i>T. monorchis</i> Riemann, 1974. <i>Trefusialaimus idrisi</i> sp. nov. is similar to <i>T. magnus</i> in the shape of the copulatory apparatus and tail, but can be differentiated from the latter by the shorter body length (4540 <i>vs.</i> 7700 <b>M</b> m), lower value of c (7 <i>vs.</i> 21), longer cephalic setae (0.65-0.80 <i>vs.</i> 0.4 cbd), longer spicules (2.3 <i>vs.</i> 1.7 abd), and longer tail (38 <i>vs.</i> 11 abd). <i>T. idrisi</i> sp. nov. can easily be differentiated from <i>T. monorchis</i> by the markedly longer cephalic setae (0.65-0.80 <i>vs.</i> 0.26 cbd), absence of pre- and post-cloacal papillae (present in <i>T. monorchis</i>), and tail shape (gradually tapering <i>vs.</i> conico-cylindrical).</p> Etymology <p>The species is named after Idris Matai Kljucanin Brun, the author’s godson.</p> Material examined <p> <b>Holotype</b></p> <p>♂, collected on 20 Feb. 2011 (NIWA cruise TAN1103, station 69), central Chatham Rise (43.331° S, 178.288° E), water depth 350 m, sediment depth 1-5 cm, mean grain size 55-59 µm, %sand 55-57%, particle sorting (geometric) 4.1-4.3 (NIWA 88349).</p> <p> <b>Paratype</b></p> <p>1 juvenile, same data as holotype (NIWA 88350).</p> Description <p> <b>Male</b></p> <p> Body cylindrical, slender, tapering slightly towards anterior extremity (Fig. 4D), with slight golden colouration due to the presence of numerous round, <i>ca.</i> 1 µm diameter, golden inclusions in the chords (i.e., longitudinal thickenings of the hypodermis protruding internally between the sectors of the longitudinal muscles; Chitwood & Chitwood 1974) (Fig. 4E). Cuticle smooth, thin, <i>ca.</i> 0.7-0.9 µm thick, except in head region (anterior to cephalic setae) where it is slightly thicker, 1.0- 1.6 µm. Head rounded, slightly set-off from body due to thickened cuticle, with three lips, each bearing two small, conical inner labial papillae 1.0- 1.5 µm long (Fig. 3B). Six outer labial setae and four cephalic setae in one circle, double-jointed; cephalic setae slightly longer than outer labial setae (0.75-0.80 cbd <i>vs.</i> 0.65 cbd). Sub-cephalic and somatic setae absent. Amphid pocket-shaped with oval aperture, <i>ca.</i> 6 µm wide by 2 µm high (Fig. 3A). Buccal cavity funnel-shaped, without teeth. Pharynx cylindrical, slightly swollen at posterior extremity, completely surrounds buccal cavity. Pharyngeal lumen lightly but distinctly cuticularised at anterior extremity (Figs 3B, 4B). Nerve ring situated at <i>ca.</i> 50% of pharynx length. Secretory-excretory system not observed. Cardia small.</p> <p> Reproductive system monorchic with single outstretched testis, <i>ca.</i> 1960 µm long. Position of testis relative to intestine difficult to ascertain. Elongated sperm cells, ca 3-5 µm wide by 13-16 µm long, with central rod and nucleus at one extremity (Fig. 3G); vas deferens <i>ca.</i> 520 µm long, without muscular ejaculatory duct. Paired, equal spicules, 2.3 abd long, slightly bent near distal one third, with broad proximal end and narrow pointed distal end; velum present (Fig. 3D). Gubernaculum with two pairs of narrow, pointed lateral crurae (Fig. 3E). Four pairs of small, conical peri-cloacal papillae (Fig. 3F). Precloacal supplements absent. Tail long, <i>ca.</i> 14% of total body length, narrow, gradually tapering, without setae (Fig. 3H).</p> <p> <b>Juvenile</b></p> <p> Similar to male, but with shorter and narrower body, shorter cephalic setae (Figs 3C, 4B), and smaller amphid. Numerous sperm cells are present throughout the pseudocoelom from <i>ca.</i> 90 µm posterior to pharynx to <i>ca.</i> 200 µm anterior to anus (Fig. 4C). Genital and copulatory (i.e., cloacal or vulval) primordia not observed.</p> Discussion <p> The presence of sperm cells in the pseudocoelom of the juvenile <i>Trefusialaimus idrisi</i> sp. nov. specimen is unusual. Some nematode species, such as <i>Oncholaimus oxyuris</i>, can transfer sperm through traumatic insemination (Coomans <i>et al</i>. 1988), a process whereby the male injects sperm directly into the body of a female (or potentially even a male or juvenile) by piercing the cuticle with the spicules. The presence of sperm cells in the juvenile specimen could be explained if a similar process occured in <i>T. idrisi</i> sp. nov. The existence of such a reproductive strategy, however, is highly conjectural because no <i>Trefusialaimus</i> females have ever been observed and (to my knowledge) traumatic insemination has not been described in the suborder Trefusiina.</p> <p> <i>Trefusialaimus idrisi</i> sp. nov. was rare at the study site, with only four specimens (the two type specimens and two juveniles in poor condition, each from a different subcore) recorded out of the 4412 individuals that were identified by Leduc & Pilditch (2013). All individuals were found in the surface (0-1 cm) sediment layer (D. Leduc, unpublished data). A single juvenile specimen (out of 4550 specimens identified from 30 locations on the New Zealand continental margin) was recorded from a site on the northern flank of Chatham Rise at a depth of 1000 m (178.500° E, 44.333° S; silt/clay content 95%) (Leduc <i>et al</i>. 2012a; D. Leduc unpublished data).</p>Published as part of <i>Leduc, Daniel, 2013, Two new free-living nematode species (Trefusiina: Trefusiidae) from the Chatham Rise crest, Southwest Pacific Ocean, pp. 1-13 in European Journal of Taxonomy 55</i> on pages 8-12, DOI: 10.5852/ejt.2013.55, <a href="http://zenodo.org/record/3822945">http://zenodo.org/record/3822945</a>
Violette Leduc, veuve d’Isabelle P.
No full textInternational audienceIsabelle P. est le premier amour dont Violette Leduc parle dans Ravages, publié en 1955. Cependant, après la censure éditoriale de Gallimard, la partie d’Isabelle est enlevée et ses apparitions dans la suite du roman sont presque toutes effacées. Il faut attendre 1966, puis 2000, pour voir cet amour republié, sous le titre Thérèse et Isabelle ; mais si l’édition de 2000 porte la mention « Texte intégral », il s’agit d’une version postérieure à la censure de Gallimard et donc incomplète. Avec la redécouverte des cahiers de Ravages de Simone de Beauvoir en 2015, il est à présent possible de voir l’importance d’Isabelle, au sein de sa partie, mais aussi dans l’ensemble du roman de Violette Leduc.Isabelle et Violette vivaient plus qu’une amourette de lycée, elles furent fiancées, mariées et mères ensemble, constituant une famille complète et harmonieuse. Malheureusement, avec l’exclusion du pensionnat de Douai de Violette, la rupture est brutale et elle se sent veuve à partir de ce moment. Par la suite, elle rencontre Cécile et Marc, mais ces amours n’arrivent pas à remplacer la première épouse. Le roman devient alors écriture du deuil de cette première relation, en en montrant les différentes étapes, du choc à l’acceptation d’être seule et indépendante.Dans ma communication, j’expliquerai l’aspect subversif du couple lesbien de Violette Leduc¬ et Isabelle P., en dépit du parcours de couple ordinaire qu’elles ont eu. Puis, suite à la rupture entre les deux mariées, j’exposerai le deuil de cet amour que fait Violette Leduc dans son manuscrit

Aulostomonema Leduc 2023, gen. nov.
No full textGenus <i>Aulostomonema</i> gen. nov. <p>urn:lsid:zoobank.org:act: E4C34AE7-53F3-4B0A-9C5F-6BF6A7668A8E</p> Type species <p> <i>Aulostomonema abyssum</i> gen. et sp. nov.</p> Diagnosis <p>Cuticle finely striated. Six outer labial setae and four cephalic setae of similar length and located in one circle; additional setae and subcephalic setae absent. Amphids circular. Mouth opening narrow, followed by elongated constriction of the anteriormost portion of the pharyngostome separating the lip region from the cuticularized, cylindrical buccal cavity. Pharynx not surrounding buccal cavity anteriorly; posterior bulb present. Cardia well developed. Male reproductive system with single anterior outstretched testis. Gubernaculum with dorsal apophyses. Tail conical.</p> Differential diagnosis <p> The new genus is tentatively placed within the Linhomoeidae, as it matches almost all aspects of the diagnosis of the family, including the arrangement of the cephalic sensilla, amphid shape, elongated cardia, and copulatory apparatus. However, <i>Aulostomonema</i> gen. nov. is characterized by a unique feature not found in other genera of the family, i.e., a constriction in the anteriormost portion of the buccal region (pharyngostome) separating the cylindrical buccal cavity from the lip region. This feature should not be confused with the inner soft skinned pad of the lip region (cheilostome) narrowing the buccal aperture of many Linhomoeidae. The constriction in the anteriormost portion of the buccal region of <i>Aulostomonema</i> is similar to the constriction found in the Siphonolaiminae (family Siphonolaimidae), anteriorly to the spear-like siphon. The new genus, however, lacks the siphon which characterizes the Sipholaiminae and possesses six outer labial setae and four cephalic setae in one circle instead of two separate circles as in the Siphonolaiminae.</p> <p> The new genus is tentatively placed within the Linhomoeinae due to the arrangement of the cephalic sensilla (i.e., six outer labial setae and four cephalic setae in one circle) and the cuticularised buccal cavity. <i>Aulostomonema</i> gen. nov. differs from all genera within the Linhomoeinae in having an elongated cylindrical buccal cavity, compared to a cup-shaped buccal cavity in all other genera within the Linhomoeinae.</p> <p> <i>Aulostomonema</i> gen.nov. differs from the genera in the subfamily Desmolaiminae which are characterized by a minute or conical buccal cavity, and which never have setiform outer labial sensilla and cephalic setae in a single circle. Within the Desmolaiminae, <i>Aulostomonema</i> gen. nov. is most similar to the genus <i>Terschellingoides</i> Timm, 1967 (subfamily Desmolaiminae) in having an elongated cylindrical buccal cavity and a single anterior outstretched testis, but differs from the latter in the arrangement of the cephalic sensilla, i.e., a single circle of six outer labial setae and four cephalic setae vs four cephalic setae only in <i>Terschellingoides</i>.</p> <p> The new genus has some affinities with the closely-related Eleutherolaiminae Filipjev, 1922 due to the cylindrical buccal cavity. However, <i>Aulostomonema</i> gen. nov. differs from all genera in this subfamily in having an elongated buccal cavity (vs short buccal cavity in the other genera) and in the arrangement of the cephalic sensilla, which in Eletherolaiminae consists of a 4 + 2 + 4, 4 + 6 or 6 + 4 arrangement.</p> Etymology <p> The genus name is derived from the Greek ʻ <i>aulos</i> ʼ meaning ʻfluteʼ, ʻpipeʼ, ʻtubeʼ, ʻ <i>stoma</i> ʼ for ʻmouthʼ and ʻ <i>nema</i> ʼ for ʻthreadʼ and refers to the shape of the buccal cavity in this genus of nematode.</p>Published as part of <i>Leduc, Daniel, 2023, New nematode species and genera (Nematoda: Chromadorea) from cold seeps on Hikurangi Margin, New Zealand, pp. 1-45 in European Journal of Taxonomy 856</i> on pages 16-17, DOI: 10.5852/ejt.2023.856.2025, <a href="http://zenodo.org/record/7522913">http://zenodo.org/record/7522913</a>
