For a discussion on the generic placement of this species in Suchonellina, see the Remarks section under S. globosa (above). The diagnosis of S. stricta follows Jones (1894) and Anderson (1964). The original proposal of the species, however, is from Brodie (1843), although the species was not formally described or illustrated in that monograph. Due to major morphological similarity between the type specimens of S. stricta and Darwinula xinpingensis Jiang in Wei et al. (1983), these are herein synonymized, as also are specimens of D. cf. D. liassica of Ye et al. (1977). Synonymy with the present species is tentative for: (1) D. liassica of Dadlez and Kopik (1963), because no size measurements for the illustrated specimens were given; and (2) Gerdalia sp. of Kietzke (1989a), also figured by Swain (1999), for having a very similar, but not equal, general layout.
