Hippocampus zosterae


H. zosterae  Jordan & Gilbert 1882

English common names. Dwarf Seahorse.

Synonyms. H. rosamondae Borodin 1928  , H. regulus Ginsburg 1933  .

Syntypes. MNHN 1887-0515, CAS-SU 1671 (2), USNM 30852 (2 or 1, not found in 1980).

Type locality. Laguna Grande, Pensacola   , Florida  .

Distribution. Bahamas, Mexico, USA (Gulf of Mexico).

Notes. The type specimen of H. lichtensteinii  is thought to possibly be H. zosterae  and to have been mistakenly labelled as being from the Red Sea ( Kaup 1856—See Appendix P and Species Inquirenda below). Although populations throughout the Floridian portion of the species’ range exhibit gene flow, mtDNA evidence (1,450 bp, ND4, D-loop, CO1) suggests four distinct subpopulations (overall F ST = 0.47, average nucleotide diversity within populations = 0.49%) ( Fedrizzi et al. 2015).
