Some asteroid specimens of genus Henricia were collected at a depth of 50-90 m near waters of Moseulpo, Jeju Island, Korea using fishing nets on September 2015. The specimens were identified as Henricia elachys Clark and Jewett, 2010 belonging to the family Echinasteridae of order Spinulosida. This small species can be distinguished from other Henricia species by short arms, moderately inflated arm base, and slightly broad disk. The morphological characteristics of this species were described with illustrations. Up to date, there are nine species of genus Henricia reported in Korean fauna.
