Zygiella is a genus of orb-weaver spiders that can be found globally. They are notable for their webs having a missing sector with it having only a single tread.
It was first described by F. O. Pickard-Cambridge in 1902. In 2015, Parazygiella was determined to be a taxonomic synonym of Zygiella, and its species were moved to Zygiella.
Identification
Zygiella species are distinguished by the structure of the web, which has a missing sector containing a signaling thread leading to a retreat. Zygiella x-notata, a species in the Zygiella genus, is well-researched for its missing-sector web construction behaviors.
