Phrurotimpus

Phrurotimpus is a genus of araneomorph spiders first described by R. V. Chamberlin and Wilton Ivie in 1935. The name is a compound adjective meaning "guarding the stone". Originally added to the Liocranidae, it was moved to the Corinnidae in 2002, then to the Phrurolithidae in 2014. They have red egg sacs that look like flattened discs, often found on the underside of stones.
