Entre los 129 capitulos que versan sobre la sistematica de Arthropoda, tres se refieren a taxones afines al grupo de artropodos: "Pentastomida", "Onychophora" y "Tardigrada"; en tanto que 126 resenan los taxones caracteristicos de Arthropoda, asi los grupos de Chelicerata se incluyen en 14 capitulos relativos a "Xiphosura", "Pycnogonida", "Palpigradi", "Schizomida", "
Uropygi", "Amblypygi", "Solifugae", "Ricinulei", "Araneae" "Scorpiones", "Pseudoscorpionida", "Opiliones", "Acari" y "Oribatei (Acari)"; y en cuatro capitulos de Myriapoda se discuten "Symphyla", "Pauropoda", "Geophilomorpha" y "Diplopoda".
Shultz, "Evolution of locomotion in arachnida: the hydraulic pressure pump of the giant whip scorpion, Mastigoroctus giganteus (
Uropygi)," Journal of Morphology, vol.
We now report that the giant whip scorpion, Mastigoproctus giganteus (Lucas) (Arachnida:
Uropygi) consumes Floridobolus, even if the quinone-based secretion is released upon attack.
They were inadvertently caught in pitfall traps used to capture large arthropods including theraphosid spiders (Orthognatha, Aphonopelina hentzi), wind scorpions (Solifugae, Eremobatidae, Eremobates sp.), scorpions (Scorpiones, Buthidae, Vaejovidae), whipscorpions (
Uropygi, Thelyphonidae, Mastigoproctus giganteus), orthopteran insects (Acrididae) and millipedes (Diplopoda).
First global molecular phylogeny and biogcographical analysis of two arachnid orders (Schizomida and
Uropygi) supports a tropical Pangean origin and mid-Cretaceous diversification.
New and rare fossil Arachnida in Cretaceous Burmese amber (Amblypygi, Ricinulei and
Uropygi: Thelephonida).
As far as we know, nothing similar to that has been reported in other arachnid orders, suggesting that these gland openings could be synapomorphic for the clade
Uropygi (sensu Shultz 1990).
Uropygi.--Nine species of fossil whip scorpion are listed by Harvey (2003:73-74, 79-80); and one further Pennsylvanian species was overlooked.
We attempted to address the problems outlined above by making a comprehensive and robust evaluation of the value of primary, secondary, and plantation forests for a Neotropical epigeic arachnid fauna (encompassing the orders Amblypygi, Araneae, Opiliones, Scorpiones, and
Uropygi).
Three arachnid orders, Amblypygi,
Uropygi, and Palpigradi share a narrow pedicel with Araneae, but the pro/ opisthosoma connection in spiders is especially flexible, probably to promote mobility of the spinnerets.
