Abstract Two symmetrical diacylguanidines, triophamine (1) and limaciamine (2), have been found to occur in three Polyceridae nudibranchs from Canary Islands. These compounds were previously reported from taxonomically related species collected from distinct geographical areas. Due to the peculiar occurrence of 1 and 2 in Polyceridae nudibranchs and, in particular, exclusively in members of Polycerinae and Triophinae subfamilies, it should be suggested that these diacylguanidines are distinctive chemical markers of this group of nudibranchs.
