According to distribution maps (IUCN, http://www.iucnredlist.org/details/183882/0) this species has been restrictively allocated to specific sites in the eastern Pacific including the Gulf of California (Mexico), Cocos Island National Park (Costa Rica), Galapagos (Ecuador) and Lobos de Afuera Island (Peru). I was wondering if there is any other unofficial/unpublished report for H. fossatus in the eastern Pacific
