“The Newcastle funnel-web, Atrax christenseni— dubbed Big Boy—is a totally new species. The ‘true’ Sydney Funnel-web, Atrax robustus centres on the North Shore of Sydney and the Central Coast, and the Southern Sydney Funnel-web, Atrax montanus, is a resurrected species name from 1914,” Loria explained.

“The Newcastle funnel-web, Atrax christenseni – ‘Big Boy’ – is a totally new species. The ‘true’ Sydney funnel-web, Atrax robustus, centres on the North Shore of Sydney and the Central Coast while the Southern Sydney funnel-web is a resurrected species name from 1914,” Dr Loria said.

Australian scientists have discovered a bigger, more venomous species of the Sydney funnel-web spider, one of the world's deadliest.
