H. coronatus Temminck & Schlegel 1850

English common names. Crowned Seahorse.

Lectotype (designated by Boeseman (1947:195–196)): RMNH D1543 (dry). Paralectotype: RMNH D 1541-42 (2, dry), D1544 (1, dry).

Type locality. Nagasaki, Japan.

Synonyms. None.

Distribution. Japan, South Korea (southeast).

Notes. Mukai et al. (2000) assessed the mtDNA 12S rRNA divergence of specimens from Sagami Bay, Japan that they identified as H. coronatus . They concluded the samples represented two different taxonomic units, 4.4–4.6% divergent from one another. It is possible that the samples were misidentified and may in fact be H. coronatus and H. sindonis (this is likely based on the photographs in the paper). The paper did not mention H. sindonis . Morphological examination of the seahorses from Sagami Bay is needed.
