The complete mitochondrial genome of an orb-weaver spider Araneus angulatus (Araneae: Araneidae).

Project description:The complete mitochondrial genome of an orb-weaver spider Araneus angulatus is 14,205 bp in length and contains 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs, and a control region. The A + T content of the major strand is 75.4%. Nine of the protein-coding genes are initiated by typical ATN codons, one gene (COI) starts with TTA and other three genes (ND6, COII, and COIII) begin with TTG. The truncated stop codon (T) occurs in ND3, ND4L, and ND6, whereas the rest ten genes end with the canonical stop codon (TAA and TAG). Fifteen tRNAs lack the potential to form the typically cloverleaf-shaped secondary structure. The control region is 649 bp in length and contains a long tandem repeat region. The result of phylogenetic analysis shows that the relationship of A. angulatus was close to the species in the same family Araneidae.

Two new species of the orb-weaver genus Chorizopes from Yunnan, China (Araneae, Araneidae).

Project description:Two new species of the orb-weaver genus Chorizopes from Yunnan Province, China are described: Chorizopes albussp. n. (male and female) from the Gaoligong Mountains and Ailao Mountains, and Chorizopes longussp. n. (male and female) from the Gaoligong Mountains. Chorizopes albussp. n. can be distinguished from the related species Chorizopes shimenensis by: 1) median apophysis widest at the middle part versus widest at the base in the latter; 2) median apophysis without the dorsal spur found in that of the latter; 3) spermathecae spherical versus ovoid in the latter; 4) having one pair of large white spots on posterior lateral area of abdomen versus having two pairs of crescent white patches with dark edges on dorsal abdomen in the latter. Chorizopes longussp. n. can be separated from the similar species Chorizopes tumens by: 1) the median apophysis having a knob on the distal half versus having a knob on the basic half in the latter; 2) male palp having a spur versus absent in the latter; 3) the width of the groove between the paracymbium and cymbium as thick as the paracymbium versus two times as thick as the paracymbium in the latter; 4) copulatory duct attached on anterior ventral of the spermatheca versus on anterior dorsal in the latter. Photos of body and copulatory organs, line drawings of copulatory organs, as well as the distribution data are provided. The type specimens are deposited in the College of Life Sciences, at the Hunan Normal University (HNU) and the Museum of Tongren University (MTU).

Revision of the new Australasian orb-weaving spider genus Salsa (Araneae, Araneidae).

Project description:A new Australasian genus in the orb-weaving spider family Araneidae Clerck, 1757 is described to include seven species: Salsafuliginata (L. Koch, 1871) comb. nov. (type species; = Epeirarubicundula Keyserling, 1887) syn. nov.) (Australia, introduced to New Zealand); S.brisbanae (L. Koch, 1867) comb. nov. (Australia); S.canalae (Berland, 1924) comb. nov. (New Caledonia); S.neneba sp. nov. (Papua New Guinea); S.recherchensis (Main, 1954) comb. nov. (Australia); S.rueda sp. nov. (Australia); and S.tartara sp. nov. (Australia; Lord Howe Island endemic). Salsa gen. nov. belongs to the Australasian informal backobourkiine clade and differs from other genera of this clade by a distinct abdominal shape (single posterior abdominal tubercle) and ventral colouration (pale lateral spindle-shaped bands), male pedipalp morphology (C-shaped median apophysis that has teeth-like tubercles inside the basal arch) and the shape of the female epigyne scape (partially translucent and generally shorter than the epigyne plate). Based mainly on male pedipalp morphology within the backobourkiines, Salsa gen. nov. has closest morphological affinities with Acroaspis Karsch, 1878 and Socca Framenau, Castanheira & Vink, 2022.

Function of bright coloration in the wasp spider Argiope bruennichi (Araneae: Araneidae).

Project description:There are two major competing explanations for the counter-intuitive presence of bright coloration in certain orb-web spiders. Bright coloration could lure insect prey to the web vicinity, increasing the spider's foraging success. Alternatively, the markings could function as disruptive camouflage, making it difficult for the insect prey to distinguish spiders from background colour variation. We measured the prey capture rates of wasp spiders, Argiope bruennichi, that were blacked out, shielded from view using a leaf fragment, or left naturally coloured. Naturally coloured spiders caught over twice the number of prey as did either blacked-out or leaf-shielded spiders, and almost three times as many orthopteran prey. Spectrophotometer measurements suggest that the bright yellow bands on the spider's abdomen are visible to insect prey, but not the banding on the legs, which could disguise the spider's outline. Thus, our results provide strong support for the hypothesis that bright coloration in the wasp spider acts as a visual lure for insect prey and weak support for the hypothesis that the arrangement of the banding pattern across the spider's body disguises the presence of the spider on the web.

Orb-web spider Argiope (Araneidae) as indigenous arrow poison of G/ui and G//ana San hunters in the Kalahari.

Project description:Hunting has been crucial in early human evolution. Some San (Bushmen) of southern Africa still practice their indigenous hunting. The use of poisons is one remarkable aspect of their bow-and-arrow hunting but the sources, taxonomic identifications of species used, and recipes, are not well documented. This study reports on fieldwork to investigate recent indigenous hunting practices of G/ui and G//ana San communities in the Central Kalahari Game Reserve (CKGR), Botswana. Here we discuss their use of spider poison. The hunters use the contents of the opisthosoma ('abdomen') of a spider as sole ingredient of the arrow poison and discard the prosoma that contains the venom-glands. Using taxonomic keys, we identified the spider as the garden orb-web spider Argiope australis (Walckenaer 1805) (Araneidae). The hunters' choice of this species is remarkable given the scientific perception that A. australis is of little medical importance. The species choice raises questions about how the spider fluids could kill game, particularly when the prosoma, which contains the venom glands, is not used. Possibilities include trauma, as a source of pathogens, or abdomen-containing toxins. Based on characteristics of Argiope Audouin 1826, we hypothesize that the choice of this species for arrow poisons might have evolved from the recognition of aposematic signalling or spiritual symbolism. Indigenous knowledge (IK) is an important source for advances in biotechnology but is in decline worldwide. The study contributes to the documentation of the San people, and their ancient IK, which is threatened by marginalization, political pressures, and climate change.
