Ophiuroidea note details
The species name galapagensis has the incorrect ending (m/f), which led to a mandatory change to galapagense (n.) by Okanishi & Fujita (2018). However, the stem of Galapagos should be galapago and consequently the name should probably be galapagoense, which may not be mandatory though.
