"Triblastula quasicribrata" O. Wetzel, 1961, p.340, pl.2, fig.3.

TYPE: Holotype: O. Wetzel, 1961, pl.2, fig.3; Sarjeant, 1985b, pl.2, fig.1; Jan du Chêne et al., 1986a, pl.46, figs.9-10.

HISTORY: NOW: Hystrichosphaeropsis. Originally Triblastula, subsequently (and now) Hystrichosphaeropsis.

SYNONYM(S): Taxonomic junior synonyms: Triblastula nuda and Triblastula tubulata, both according to Marheinecke (1992, p.44); (at specific rank) Deflandrea (as Amphidiadema) rectangularis subsp. samuelsonii, according to Gocht (1976, p.322).

COMMENTS: Contrary to the opinion of Stover and Evitt (1978, p.94), Gocht (1976, p.322) did not consider this species to be the taxonomic senior synonym of Amphidiadema rectangularis, but only the specimen identified by Kjellström (1973, p.17).
