H. jugumus Kuiter 2001 English common names. Collar Seahorse, collared seahorse. Synonyms. None. Holotype. AMS IA.2424. Type locality. Lord Howe Island, Australia. Distribution. Australia (Lord Howe Island). Notes. This species was described on the basis of a single specimen, however since then a second specimen has been collected from Lord Howe Island (from the gut of a kingfish Seriola lalandi Valenciennes 1833), and is now deposited at the Australian Museum in Sydney. Hippocampus jugumus looks superficially similar to the species described as H. pusillus and H. fisheri, however the meristics do not agree (Lourie et al. 1999; Kuiter 2001; Fricke 2004). Additional research is required to determine the relationships among these three species.
