NEW SPIDERS (ARANEAE: MESOTHELAE), FROM THE CARBONIFEROUS OF NEW MEXICO AND ENGLAND, AND A REVIEW OF PALEOZOIC ARANEAE
The fossil record of Paleozoic spiders is sparse, but, herein, the number actually belonging to that arachnid order is reduced to 24, and changes are presented of species in the Arthrolycosidae.
The oldest haplogyne spider (Araneae: Plectreuridae), from the Middle Jurassic of China
New fossil spiders from Middle Jurassic strata of Daohugou, Inner Mongolia, China are described as Eoplectreurys gertschi gen. et sp.
RESISTANCE OF SPIDERS TO CRETACEOUS‐TERTIARY EXTINCTION EVENTS
- Geography, Environmental ScienceEvolution; international journal of organic evolution
It is provided the first evidence that spiders suffered no decline at the family level during these mass extinction events, and it is shown that they increased in relative numbers through the Cretaceous and beyond the CRETaceous—Tertiary extinction event.
Phylogenomic Analysis of Ultraconserved Elements Resolves the Evolutionary and Biogeographic History of Segmented Trapdoor Spiders.
- BiologySystematic biology
The important role of major tectonic events in shaping the evolutionary history, present-day diversity, and geographical distribution of mesothele and liphistiid spiders is highlighted.
The Fossil Arachnida
It was concluded that the position of Phalangiotarbida and Haptopoda remains obscure and Kustarachnida, according to Dunlop (1996a, b), represents misidentified opilionids.
Cretaceous arachnid Chimerarachne yingi gen. et sp. nov. illuminates spider origins
- BiologyNature Ecology & Evolution
A new Cretaceous arachnid fossil encased in Burmese amber sheds light on the evolution of spiders, as it preserves both primitive and derived features, suggestive of a basal Araneae position.
Pre‐Pleistocene geological events shaping diversification and distribution of primitively segmented spiders on East Asian margins
This work explored biogeographical histories and population genetic structures of the primitively segmented spiders, Heptathela and Ryuthela (Liphistiidae), broadly codistributed across EAM islands, and looked for geohistoric events that may have shaped their distributional patterns.
A genus-level taxonomic review of primitively segmented spiders (Mesothelae, Liphistiidae)
This work revises liphistiid genus level taxonomy based on original sampling throughout their Asian range, and on the evidence from a novel molecular phylogeny, and provides strong support for the monophyly of Liphistiidae, and the two subfamiliesliphistiinae and Heptathelinae.
Changes in the chemical profile of cephalic salivary glands of Scaptotrigona postica (Hymenoptera, Meliponini) workers are phase related
- BiologyThe Journal of Experimental Biology
The chemical composition of cephalic salivary (labial) glands of Scaptotrigona postica varies according to the worker's life phase and tasks performed, increasing as the individual moves from intra- to extra-colonial activities.
