Chevreux (1925a) described the new species L. serratum. However, this name is a homonym of L. serratum Stephensen, 1925. In an erratum slip, issued with his second paper on the amphipods collected during the voyages of the schooner Melita, Chevreux (1925b) recognised this homonymy and proposed the new name L. crenulatum. Gurjanova (1938), apparently unaware of Chevreux' s correction, introduced the replacement name L. chevreuxi which has been used since. Based on priority, Lepidepecreum
crenulatum is the valid name for the species.
