Araneomorphae - Haplogynae
Labidognatha
The Araneomorphs comprise the majority of spiders. In these spiders the fangs are convergent and thus usually cross or come close to crossing. In addition, there is usually only one pair of book lungs (exception Hypochilidae) and a tracheal opening is present. In most araneomorphs this spiracle is located just anterior to the spinnerets, but in the Anyphanidae the spiracle may be located near the middle or even in front of the middle of the ventral abdomen. Many species spin webs. All are predators.
