Hadronyche flindersi

Hadronyche flindersi, also known as the Flinders Ranges funnel-web spider, is a species of funnel-web spider in the Atracidae family. It is endemic to Australia. It was described in 1984 by Australian arachnologist Michael R. Gray.

Description
The carapace is a glossy brownish-black in colour, the back and sides of the abdomen a dark maroon-brown with a paler, pinkish, underside. There are four pairs of pale markings on the upper and lateral surfaces. The venom contains excitatory neurotoxins.

Distribution and habitat
The species occurs in the southern Flinders Ranges of South Australia. The type locality is on the lower slopes of Mount Remarkable, 3 km north of Melrose. The spiders are found in open forest and woodland habitats.

Behaviour
The spiders construct burrows, without surface triplines, in or beneath leaf litter. The burrows contain a side chamber and have an entrance with a soil door in a collapsible silk collar.
