Revision der Spinnenfamilie Psechridae (Arachnida: Araneae): Biodiversitätsforschung und Phylogenie mithilfe morphologischer und molekularer Methoden
No full textDie vorliegende, publikationsbasierte Dissertation, bestehend aus den drei Einzelpublikationen Bayer (2011, 2012) und Bayer und Schönhofer (2012), verfolgte das Ziel, die Spinnenfamilie Psechridae zu revidieren. Weiterhin sollten die phylogenetische Position dieser Familie im System der höheren Webspinnen (Araneomorphae) sowie die phylogenetischen Beziehungen der einzelnen Arten innerhalb der beiden Gattungen der Psechridae untersucht werden. In Form von morphologisch-taxonomischen Bearbeitungen wurden die beiden die Psechridae bildenden Gattungen Psechrus und Fecenia revidiert, wobei sämtliches Typus-Material sowie reichhaltiges, weiteres Material eingehend beschrieben, illustriert und diagnostiziert wurde. Hierbei wurden auch intraspezifische Variabilität sowie die Prä-Epigynen subadulter Weibchen, die in taxonomischen Arbeiten bislang nur eine unwesentliche Rolle gespielt haben, beschrieben, illustriert und taxonomisch ausgewertet. Zudem wurden im Rahmen dieser Untersuchungen bereits Überlegungen über mögliche Verwandtschaftsbeziehungen innerhalb der beiden Gattungen angestellt. ..

Measurements of palp and legs. Palp 10.5–12.1 [3.5 –4.0, 1.8–2.2, 1.4–1.6, 3.7–4.3], I 64.0– 80.7 [16.7–21.5, 3.9–4.6, 17.7–23.3, 18.2 –23.0, 7.5–8.3], II 48.1–58.7 [13.0– 16.7, 3.4–4.2, 13.0– 15.8, 13.1–15.9, 5.5–6.1], III 33.3–47.8 [9.6–10.8, 2.6–2.9, 7.9–9.4, 9.2–10.5, 4.0– 4.2], IV 49.6–62.3 [13.6–17.4, 3.1–3.6, 12.5–16.3, 14.3–18.1, 6.1–6.9]. Leg formula: 1423. FEM-I+MTT-I/CL= 4.31–4.54, legs in relation to other species-groups short and generally within the range for species of the sinensis -group. Palpal femur ventrally modified with a quite strongly extended, rounded bulge. Macrosetae ventrally on coxa of leg I present, but inconspicuous and only as apical row, none on trochanter of leg I. Female (measurements and spination patterns listed in Bayer 2012 are here partly included; for spination, leg formula, cheliceral dentition etc. the most common patterns are listed first, the less common ones in parentheses with the most uncommon rightmost): Body and eye measurements: Carapace length 8.7–10.9, maximal carapace width 4.2–7.9, anterior width of carapace 3.7–4.8, opisthosoma length 12.9–15.5, opisthosoma width 6.8–11.6. Eyes: AME 0.41–0.51, ALE 0.50–0.57, PME 0.48–0.58, PLE 0.49–0.57, AME–AME 0.27–0.28, AME–ALE 0.08–0.11, PME–PME 0.39–0.43, PME–PLE 0.43–0.52, AME–PME 0.66–0.86, ALE–PLE 0.61–0.76, clypeus height at AME 1.31–1.51, clypeus height at ALE 1.03–1.27. Cheliceral furrow with three promarginal and five (four) retromarginal teeth. Palpal claw with 15–16 (14) teeth. Spination: Palp: 131, 110, 1101, 1014. Legs: femur I 546 (536,535), II 545 (556,536), III 545 (555,536,556), IV 554 (555); patella I–IV 000; tibia I 3036 (3026,2036), II 3036 (3026), III 2022 (2032), IV 2023 (2022,2032,2033); metatarsus I 3035 (3033), II–III 3035, IV 3034 (3024,3014). Measurements of palp and legs: Palp 10.2–12.8 [3.5–4.4, 1.5–1.8, 1.8–2.3, 3.4–4.3], I 48.0– 58.6 [12.7–15.9, 3.7–4.9, 13.4–16.9, 12.6–14.8, 5.6–6.1], II 37.3–45.8 [10.3–13.6, 3.2–4.3, 10.3–12.5, 9.2–10.7, 4.3–4.8], III 26.8–32.3 [8.0– 9.9, 2.3–3.2, 6.6–7.9, 6.6–7.8, 3.3–3.5], IV 38.2–47.1 [10.5–13.7, 2.9–3.8, 10.1–12.5, 10.0– 11.9, 4.7–5.2]. Leg formula: 1423. FEM-I+MTT-I/CL= 2.81–2.91, thus legs short in relation to females of other speciesgroups. The legs range within the spectrum listed in Bayer (2012, p. 96) for females of the sinensis -group. Colouration of male and female (see also description for sinensis -group and Psechrus in Bayer 2012): Median bands on carapace hardly to slightly serrated, lateral bands hardly to slightly serrated and rather narrow (ca. 0.7–0.9 diameter of PME) or absent. Light longitudinal line ventrally on opisthosoma subdistally broken or if continuous, then subdistally constricted. Distal section (patch) broader than pre-subdistal section. Longitudinal line broad, width (measured centrally on opisthosoma) is 0.70–0.9 x the width of one half of the cribellum. Intraspecific variation of copulatory organs: Males: Intraspecific variation is low. The prolatero-distal part of embolus base differs slightly between SB 1236 (Fig. 15 A), SB 1234 (Fig. 15 C) and the holotype (Bayer 2012, fig. 57 b). The most proximal part of the tegulum may show an inconspicuous proximal bulge in retrolateral view (Fig. 15 B, 26 F). In SB 1236 and SB 1234 the central section of the tegulum seems slightly stouter than in the holotype. Consequently, in the former the subtegulum is more clearly visible beneath the tegulum (Figs 15 A,C, 25 F). Females: As illustrated in Bayer (2012, figs 58 a, 58 f) epigynes of this species are relatively variable in basic shape, sometimes broader and shorter (fig. 58 a), sometimes rather slim and elongated (fig. 58 f). The newly collected female shows an intermediate character state in this context (Figs 16 A, 29 B). The transversal section of the initial part of the copulatory duct that represents the dorsal part of the twisted section of the copulatory duct seems to be slightly broader in SB 1238 (Fig. 16 B) than in the paratypes (Bayer 2012, figs. 58 b,g). Additionally the spermathecal head may exhibit a small outgrowth (Fig. 16 B, left half of vulva). Distribution. Vietnam (Fig. 34).Published as part of Bayer, Steffen, 2014, Seven new species of Psechrus and additional taxonomic contributions to the knowledge of the spider family Psechridae (Araneae), pp. 1-54 in Zootaxa 3826 (1) on pages 26-28, DOI: 10.11646/zootaxa.3826.1.1, http://zenodo.org/record/28642

Material examined (1 ♂, 1 s.a. ♂): LAOS: Champasak Prov.: Bolaven Plateu, Muang Bachieng, Ban Lak 35, That I-Tou, 15 ° 11 ' 37.7 ''N, 106 °06'06.3''E, 810 m, coffee plantation with remnants of secondary forest, in vegetation, P. Jäger leg. at night, 16.XI. 2012, ♂ (SB 1248), s.a. ♂ (SB 1249), SMF 64074. Remarks. In Bayer (2012) only one male of this species was available for examination. To provide readers with some appreciation of the intraspecific variation a description of the male listed above and images of its copulatory organ (Figs 25 C, 26 C) are given. Description. Male: Body and eye measurements: Carapace length 7.0, maximal carapace width 4.8, anterior width of carapace 2.9, opisthosoma length 10.2, opisthosoma width 3.6. Eyes: AME 0.37, ALE 0.43, PME 0.44, PLE 0.44, AME–AME 0.16, AME–ALE 0.04, PME–PME 0.22, PME–PLE 0.34, AME–PME 0.61, ALE–PLE 0.39, clypeus height at AME 0.86, clypeus height at ALE 0.76. Cheliceral furrow with three promarginal and four retromarginal teeth. Spination: Palp: 131, 0 10, 1101 (all spines less than half as long as those on palpal femur); legs: femur I 566 {555}, II 556 {566}, III–IV 555; patella I–IV 000; tibia I–II 3038, III 3034, IV 3036 {3035}; metatarsus I–IV 3035. Measurements of palp and legs: Palp 8.5 [3.2, 1.4, 1.1, 2.8], I 57.4 [15.1, 3.2, 15.7, 16.5, 6.9], II 46.3 [12.7, 2.9, 12.2, 13.0, 5.5], III 32.2 [9.5, 2.2, 7.9, 8.8, 3.8], IV 48.5 [13.2, 2.6, 12.6, 14.2, 5.9]. Leg formula: 1423. FEMI+MTT-I/CL= 4.51. Thus, legs short to medium-sized. In males of the himalayanus -group this value is usually slightly higher (on average ca. 5). Palpal femur without modification and virtually straight. Intraspecific variation of male copulatory organs: This male only shows slight differences to the paratype male (Bayer 2012, figs 48 a–d, 50 f, 85 n). In comparison to the paratype male the position of the conductor of the present male seems slightly shifted retrolaterally (Figs 25 C). The shape and position of the embolus is similar to that of the paratype male. Colouration. As described in Bayer (2012, p. 94), but in the new male the lateral bands on carapace are not distinctly narrow (ca. 1.25 diameter of PME). Distribution. Laos, Thailand.Published as part of Bayer, Steffen, 2014, Seven new species of Psechrus and additional taxonomic contributions to the knowledge of the spider family Psechridae (Araneae), pp. 1-54 in Zootaxa 3826 (1) on pages 20-21, DOI: 10.11646/zootaxa.3826.1.1, http://zenodo.org/record/28642

Les deux voyages de F. Pérez Bayer au Portugal: 1782, 1783
No full textFrancisco Pérez Bayer accomplit deux voyages au Portugal. Le premier, qui fit suite à une mission archéologique en Andalousie effectuée à l\u27instigation de l\u27Académie d\u27Histoire de Madrid, se déroula du 31 octobre au 8 décembre 1782. L\u27érudit parcourut les régions à l\u27ouest de Badajoz et séjourna à Lisbonne, terminant par une visite de Mafra. Le second eut lieu au mois de juillet 1783 et lui permit de visiter Coimbre et son université réformée, ainsi que Porto. J’ai cherché à montrer avec quelle précision Pérez Bayer nous renseignait sur les conditions matérielles du voyage à son époque, dans une optique péninsulaire qui donne à l\u27Espagne et au Portugal des traits communs, parfois comparables à ceux qui caractérisent les nations en voie de modernisation, mais le plus souvent décalés par rapport à elles, et fait aussi ressortir leur mutuelle autonomie, dans le domaine de la législation, du niveau de vie, ainsi que leurs différences, au plan des moeurs ou simplement du climat
