#kwonkan

Not the spider itself, obviously, since she is staying deep underground away from the heat and daylight, but the very distinctive entrance to her burrow, disguised with fine laterite gravel and surrounded by carefully selected larger pieces. At night, she'll listen for the sound of anybody walking past, and lunge out to seize them.

Kwonkan wonganensis is a Anamid that lives in y-shaped burrows in open woodland in what is now the Avon Wheatbelt, so it's only found in the surviving reserves.  It was described in 1977 by Australian arachnologist Barbara York Main.

There were a LOT of these burrows either side of the track in Rogers Reserve.
