Satomi’s Pygmy Seahorse . Synonyms. H . waleananus Gomon and Kuiter 2009 . Distribution. Brunei , Indonesia ( Kalimantan ), Malaysia ( Sabah ). Holotype. NMV A25420-001. Paratype : NMV A25420-002. Type locality. Derawan Island , Kalimantan , Indonesia. Notes. Hippocampus waleananus was described based on a single specimen. Differences cited included tail rings (32 vs. 27–28 for H. satomiae ) and dorsal fin rays (12 versus 13-14), however a lack of other differences, and its apparent distribution entirely encompassed within the distribution of H. satomiae , lead us to synonymize it under H. satomiae (Appendix M). Further surveys and molecular studies in the region are needed to confirm this.
