Adults are dark red-brown to almost black and about 3-5 mm in body length; sometimes adult is shining and glabrous, dull and coarsely granulate, densely pubescent or covered with scales. Elytra terminate in a rounded or blunt slope (the declivity) which is concavely excavated with lateral margins dentate, all teeth on summit (I. grandicollis belongs to a group with 4 spines on the elytral declivity). They are distinguished from other bark beetles by their scooped-out posterior with 4 to 6 spines on each side; Australia: 67km N Brisbane, 8 Nov 1982, M. DeBaar & F.R. Wylie.
