Labidognatha
Quick Summary
Labidognatha is a taxonomic synonym for araneae verae, which refers to araneomorph spiders. This suborder is one of three within the order Araneae (spiders), alongside Mesothelae (segmented spiders) and Orthognatha (mygalomorph spiders). Araneomorph spiders are distinguished by their labidognath chelicerae, which move sideways and together, unlike the orthognath movement (forward and down) seen in mygalomorphs.123
Key characteristics of araneomorph spiders include:
* Chelicerae attached below the carapace.2
* Pedipalpal coxae with endites.2
* Typically one pair of book lungs, though sometimes replaced by tracheae.2
* The heart usually has three ostia.2
This infraorder encompasses a vast majority of known spider species and includes numerous families such as Salticidae (jumping spiders), Linyphiidae (sheet-web weavers), and Araneidae (orb weavers).2
