Notice bibliographique
Résumé
Pergalumna (Pergalumna) convergens sp. nov. (Figure 3) Type material. Holotype (male) and two paratypes (one male and one female): Northwestern Venezuela, Zulia State, El Tucaco, 200 m a.s.l., pasture meadow, 19.IV.1981 (L. Masner). The holotype is deposited in the collection of the Canadian National Collection, Ottawa, Canada; two paratypes are in the collection of the Tyumen State University Museum of Zoology, Tyumen, Russia. All specimens are preserved in 70% solution of ethanol with a drop of glycerol. Diagnosis. Body length 765–930. Body surface densely microgranulate; dorsocentral part of prodorsum with short ridges; notogaster, pteromorph, genital and anal plates striate; epimere I, lateral part of epimere II, anterior part of pteromorph foveolate. Rostrum rounded, with two lateral teeth. Anterodorsal part of prodorsum with three large longitudinal ridges. Lamellar and sublamellar lines convergent at ventral ends. Rostral, lamellar, interlamellar, and bothridial setae setiform, barbed; le longest, in shortest. Dorsosejugal porose area absent. Dorsosejugal suture complete. Notogaster with lenticulus. Octotaxic system represented by three pairs of rounded/oval porose areas; Aa located closer to lm than to la. Median pore absent. Opisthonotal gland opening and lyrifissure im located anterolaterally to A2 and distanced from it. Epimeral setal formula 2-0-3-3; setae 1a, 3a represented by alveoli. Circumpedal carina long, directed to epimere I. Anogenital setae comparatively short. Adanal lyrifissure slightly oblique, located close to posterior half of anal plate. Postanal porose area absent. Leg famulus slightly bent mediodistally, directed forwards, inserted between seta ft” and solenidion ω 2; solenidion on tibia IV inserted in anterior half of dorsal part of the segment but near to the middle. Description. Measurements. Body length 825 (holotype), 765 (male paratype), 930 (female paratype); notogaster width 690 (holotype), 645 (male paratype), 750 (female paratype). Integument. Body color dark brown to black. Body surface densely microgranulate (granules larger in basal part of prodorsum). Additionally: dorsocentral part of prodorsum with short ridges; notogaster and pteromorph heavily striate; genital and anal plates, region nearly anal aperture slightly striate; epimere I, lateral part of epimere II, anterior part of pteromorph distinctly foveolate (diameter of foveola up to 11). Prodorsum. Rostrum narrowly rounded, with two lateral teeth. Anterodorsal part of prodorsum with three large longitudinal ridges. Lamellar and sublamellar lines slightly thickened, parallel mediobasally, curving backwards and convergent at ventral ends. Rostral (97–112), lamellar (116–131), interlamellar (49–56), and bothridial (97– 116) setae setiform, barbed; ro and le thicker than in and bs; insertion of lamellar seta distanced from lamellar line; exobothridial seta not observable. Dorsosejugal porose area absent. Dorsophragma long, elongate longitudinally. Notogaster. Dorsosejugal suture complete, convex medially. Lenticulus well visible but without distinct border. Ten pairs of notogastral setae represented by setal alveoli. Octotaxic system represented by three pairs of porose areas, Aa 15–19 × 11–15, oval, transversely oriented, A2 and A3 11–15, rounded; Aa slightly distanced from pteromorphal hinge, located closer to lm than to la. Median pore absent. Opisthonotal gland opening and all lyrifissures distinct: gla and im located anterolaterally to A2 and distanced from it; ip posterolateral to A3; ih and ips slightly distanced from each other, anteromedially to p 3. Gnathosoma. Similar to Sacculogalumna zuliaensis except sizes. Subcapitulum size 195–199 × 169–172; a 26–30, m 19, h 37–41, adoral seta 26; m slightly thinner than a and h. Chelicera length 243–247; cha 77–82, chb 56–60. Palp length 165–169; postpalpal seta 11. Epimeral and lateral podosomal regions. Epimeral setal formula 2-0-3-3; setae 1a, 3a represented by alveoli, others (1b, 3b, 3c, 4c 37–41, 4a, 4b 22–30) setiform, slightly barbed. Circumpedal carina long, directed to epimere I. Anogenital region. Anogenital setal formula 6-1-2-3; genital setae (g 1 34–37, g 2 30–34, g 3 – g 6 19–30) setiform, slightly barbed; anterior edge of genital plate with two setae but third seta located near to them; aggenital, anal, and adanal setae not observable (only alveoli visible); aggenital seta located posterolateral to genital aperture; adanal setae ad 1 and ad 2 posterior, ad 3 lateral to anal plate; distance ad 1 – ad 2 shorter than ad 2 – ad 3. Adanal lyrifissure slightly oblique, located close to posterior half of anal plate. Postanal porose area absent. Legs. Similar to Sacculogalumna zuliaensis but median claw slightly thicker than lateral claws, and famulus slightly bent mediodistally. Remarks. Pergalumna (Pergalumna) convergens sp. nov. is similar to P. (P.) cubaensis Ermilov & Tolstikov, 2015 from Cuba in its main morphological traits: large body size; notogaster, pteromorphs, genital and anal plates striate; rostrum rounded; interlamellar seta medium-sized; bothridial seta setiform; dorsosejugal suture complete; three pairs of rounded/oval notogastral porose areas; dorsosejugal and postanal porose areas absent; median pore absent; adanal lyrifissure oblique. However, the new species differs from the latter by the following main traits: smaller body size (length 765–930 versus 962–1029); the presence (versus absence) of three strong longitudinal ridges on the prodorsum; convergent distally (versus parallel) lamellar and sublamellar lines; the presence (versus absence) of foveolae on the epimeres I, II and in anterior part of the pteromorphs; the presence (versus absence) of the lateral teeth on the rostrum; long (versus medium-sized) circumpedal carina. Etymology. The species name convergens refers to convergent mediodistally lamellar and sublamellar lines.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
