Henricia aspera robusta Djakonov, 1949: 30 ; 1958: 310. — Chang et al., 1964: 66.— Xu, 1994: 637. — Liao & Sun, 1996: 467, fig. 18 – 17.

Henricia aspera Liao, 2008: 852 [Non H. aspera Fisher, 1906 ].

Material examined. Yellow Sea. One (R 37 – 33 mm, r 9.9 mm, R: r 3.7 – 3.3), Dry specimen, Xiaoping Island, SW Dalian; Two (R 39 – 35 mm, r 10.5 mm, R: r 3.7 – 3.3; R 39 – 34 mm, r 12.4 mm, R: r 3.1 – 2.7), MBM 175718, CN Y 36 B-32, 28 Jan 1959; One (R 36 – 34 mm, r 10.2 mm, R: r 3.5 – 3.3), Dry specimen, 54m, sandy mud, 28 Jan 1959; One (R 31 – 29 mm, r 8.5 mm, R: r 3.6 – 3.4), Dry specimen, CN Y 0205, Stn. Y 205, 38° 26 ʹN, 121 ° 34 ʹE, 54m, 26 Jul 1957.

Distribution. Yellow Sea, Okhotsk Sea, Sakhalin, Kurile Island, 54– 300m.

Remarks. This subspecies is recognized by its sturdy body form ( Fig. 4 A). Arms are short and swollen, constricted at base; abactinal skeletons ( Fig. 4 E) form a wide meshwork with large and sunken papular area; 3 to 8 small and sharp spinelets are generally arranged in comb-shape ( Fig. 4 C) along the ridge surrounding papular areas. Specimens examined exactly agree with the description of Henricia aspera robusta by Chang et al. (1964).
