Distribution. Determining the distribution of this species is problematical, mainly because of its past confusion with L. pulex. Material in the USNM is mainly from the N. W. Atlantic Ocean, as might be expected. Considering the above synonymy, more reliable records are as follows. In the Atlantic Ocean: from about 40 ° N, throughout the tropical regions, and as far south as 31 ° S, off Brazil. In the Pacific Ocean: mainly from the tropics off Chile and Peru, the Gulf of California, the China Sea and near Japan, and the Tasman Sea, off eastern Australia. In the Indian Ocean: mainly from the tropical south-west and also the Red Sea. The SAMA also has several specimens collected from off the north-western coast of Western Australia. It has also been recorded from the Mediterranean Sea. Most of these records are from near the surface.
