Hippocampus sindonis


H. sindonis  Jordan & Snyder 1901

English common names. Sindo’s Seahorse, Shiho’s seahorse. Synonyms. None.

Holotype. USNM 47930.

Type locality. Totomi Bay, off Hamamatsu , Japan. 

Distribution. Japan.

Notes. Genetic data (714bp, 12S rRNA) from specimens identified by Mukai et al. (2000) as H. coronatus  from Sagami Bay, Japan, separated into two distinct clades that differed by 4.4–4.6%. Photographs from that same paper, however, appear to be H. sindonis  and H. coronatus  , which would explain the observed genetic divergence.
