quasicribrata (Wetzel, 1961, p.340, pl.2, fig.3) Gocht, 1976, p.322. Holotype: Wetzel, 1961, pl.2, fig.3; Sarjeant, 1985b, pl.2, fig.1; Jan du Chêne et al., 1986a, pl.46, figs.9-10; Dietz et al., 1999, fig.10, no.9. Originally Triblastula, subsequently (and now) Hystrichosphaeropsis. Taxonomic junior synonyms: Deflandrea rectangularis var. samuelsonii (as Amphidiadema rectangularis subsp. samuelsonii), according to Gocht (1976, p.322); Triblastula nuda and Triblastula tubulata, both according to Marheinecke (1992, p.44). 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, fig.17). Age: ?Late Cretaceous (erratic).
