English: Zygiella

Zygiella is a genus of orb-weaver spiders first described by F. O. Pickard-Cambridge in 1902.[2] In 2015, Parazygiella was determined to be a taxonomic synonym of Zygiella, and its species were moved to Zygiella.[3]
Identification

Zygiella species are distinguished by the structure of the web, which has a missing sector containing a signaling thread leading to a retreat.[4] Zygiella x-notata, a species in the Zygiella genus, is well-researched for its missing-sector web construction behaviors.[5]
