Antimerus is a genus of rove beetles found in eastern Australia.[1][2]
Antimerus are relatively large for rove beetles, with adults reaching 13-20 mm in length. They are robust and more or less parallel-sided, with the head approximately the same width as the rest of the body. The mandibles are relatively long, falcate and usually lack distinct internal teeth. The deflexed hypomera of the pronotum are usually visible in lateral view (concealed in A. monteithi). The first four tarsomeres on all legs are broad and bear tenent setae ventrally, and all tarsi bear one pair of empodial setae. Some species have a metallic appearance.[2]
Putative larvae of three species (A. metallicus, A. punctipennis and A. smaragdinus) are known. They are 8-16 mm long with head widths of 1.5-3.0 mm. The head is large, subquadrate and well-sclerotised. The thorax is much narrower than the head. The abdomen is fusiform and, in well-fed larvae, may be wider in the middle than the head is. The surfaces of the body are generally microspinose or microtuberculate, and covered in fine simple setae. Most macrosetae and many medium-sized setae are club-shaped and have multispinose tips.[2]
