  Missing-sector Orbweb Spiders

  Zygiella is a genus of orb-weaver spiders distinguished by their distinctive webs, which feature a missing sector containing a single signaling thread that leads to a tubular retreat. First described by F. O. Pickard-Cambridge in 1902, the genus underwent taxonomic revision in 2015 when Parazygiella was synonymized with Zygiella. The genus has a global distribution, with species found across Europe, North America, Asia, and introduced populations in South America and elsewhere.
