Araneae

Tholia tuberculata, copyright Ed Nieuwenhuys.


Belongs within: Tetrapulmonata.
Contains: Drassus, Arthrolycosidae, Liphistiidae, Mygalomorphae, Araneomorphae.

The Araneae, spiders, are a diverse group of arachnids in which the chelicerae are modified to bear venomous fangs. Silk is produced from an array of spinnerets at the end of the abdomen. In most living spiders, forming the clade Opisthothelae, all trace of external segmentation has been lost from the abdomen; segments are still visible on the abdomen of the remaining spiders in the Mesothelae.

Characters (from Jocqué & Dippenaar-Schoeman 2007): Body divided between cephalothorax (prosoma) and abdomen (opisthosoma), connected by narrow pedicel. Cephalothorax with cephalic and thoracic regions sometimes clearly demarcated by cervical groove; fovea often present behind cervical groove. Eight or fewer eyes present in cephalic region. Venter of cephalothorax with undivided sternal plate, usually marked anteriorly by labiosternal junction. Chelicerae consisting of stout basal section (paturon) and movable distal fang; fang usually resting in groove (cheliceral furrow); duct opening at tip of fang leading to venom gland in cephalothorax. Chewing mouthparts (endites) form from expansion of coxae of pedipalps; rim of endites bearing cuticular serrated ridge (serrula); promargins of endites fringed with scopulae; labium present between endites. Pedipalps six-segmented, metatarsus absent; female pedipalps simple, usually bearing single tarsal claw; male pedipalps with distal segments modified into secondary copulatory organ, with genital bulb consisting of more or less sclerotised tegulum, with winding sperm ducts, and intromittant embolus. Four pairs of seven-segmented legs present; leg tarsi bearing two or three claws. Abdomen bearing usually three pairs of spinnerets in front of anal opening. Respiratory system comprising one or two pairs of booklungs, and one or two pairs of tubular tracheae. Genitalia opening externally within epigastric groove running transversely across venter of abdomen close to pedicel.
