Sara A. Lourie, Riley A. Pollom & Sarah J. Foster, 2016, A global revision of the Seahorses Hippocampus Rafinesque 1810 (Actinopterygii: Syngnathiformes): Taxonomy and biogeography with recommendations for further research, Zootaxa 4146 (1), pp. 1-66 : 16

H. barbouri Jordan & Richardson 1908

English common names. Barbour’s Seahorse, zebra-snout seahorse.

Holotype. USNM 61683. Paratypes: CAS-SU 20205 (2).

Type locality. Cuyo , Philippines.

Synonyms. H. arnei Roule 1916 (in part) (and its misspellings H. aimei and H. airnei ).

Distribution. Indonesia (Java, Sulawesi and Borneo), Malaysia (Sabah), Philippines.

Notes. H. arnei is synonymized, in part, with H. barbouri on the basis of the original morphological description, illustrations, and photographs of the type specimens ( Lourie et al. 1999). Note that the specimens of H. arnei are both female, and apparently of two different species, and are not male and female as Roule indicates. Genetic variation (648 bp, CO1) within H. barbouri is approximately 1.1% while the distance to the closest members of the H. angustus clade (from the Torres Strait) is approximately 6.1% (BOLD 2016).
