Asteroid specimens of the genus Diplopteraster were collected by trawling nets at a depth of 93 m on 05 November 2016 from the Korea Strait ($33^{\circ}41^{\prime}N$, $127^{\circ}26^{\prime}E$). The specimens were identified as Diplopteraster multipes(M. Sars, 1866), which belongs to the family Pterasteridae, order Velatida. This species is similar to other Diplopteraster species in its pentagonal stellate shape, but is distinguished by having each paxilla composed of a protruded spine, more than eight spiracles, and regularly reticulated muscular bands. It is not commonly found in shallow water. This is the first report of the genus Diplopteraster and D. multipes in Korea.

An asteroid specimen was collected from Jumunjin, Gangwon-do in the East Sea, Korea at a depth of 50 m using fishing nets on 26 May 2013. It was identified as Pteraster militaris (O.F. $M{\ddot{u}ller$, 1776) belonging to the family Pterasteridae of the order Velatida based on morphological characteristics. This species is usually distributed in the cold boreal zone around northern Pacific and Atlantic, and is distinctly distinguished from P. tesselatus which was reported in Korean fauna: body form, length ratio of arm to disc and surface of dorsal membrane.
