Echelus polyspondylus McCosker & Ho, 2015:73, figs. 1–3. (type locality: Dong-gang, southwestern Taiwan).

Remarks. Some specimens of this species were previously misidentified as Myrophis microchir, which indicates the similarity between these two groups. This is a deepwater species, occasionally collected by bottom trawl off northeastern and southwestern Taiwan.
