The Red-jawed Spider is a rare species in an uncommon genus. There are five Australian species in the genus Xamiatus erected by Dr Robert Raven in 1981 Including the big Xamiatus magnificus. The Red-jawed is found in South East Queensland near creeks. Its name comes from its very red to dark-pink chelicerae, or jaws. It is a dark brown spider, usually about 4cm in body length, robust and heavy and quite aggressive. It has a straight burrow with no offshoot, possibly due to its relative size, aggression and strength, making it unnecessary to retreat from intruders. The species name rubifrons means red-fronted. Little is known of its biology or venom, but its large fangs suggest it is capable of delivering painful and possibly dangerous bites.
