Abstract
The pontoniine shrimp genus Ancylomenes Okuno & Bruce, 2009 now includes 17 Indo-West Pacific species (Okuno & Bruce 2009). With a few exceptions, such as A. aesopius (Bate, 1863) and A. longicarpus (Bruce & Svoboda, 1983), these present a highly consistent morphology, differing at species level principally in details of the rostrum, third abdominal somite, ophthalmic process, dentition of the second pereiopod chelae, and ambulatory propods and dactyls. This consistency renders detailed descriptionsrepetitive and largely redundant. Some specimens of Ancylomenes collected in the northern Kimberley region of Western Australia during the Western Australian Museum 2010 Kimberley Survey, were found to belong to an undescribed species, which is now described and illustrated. Specimens are deposited in the collections of the Western Australian Museum, Perth (WAM) and the Queensland Museum, Brisbane (QM).
