Apiculatasporites plicatus was named by Visscher (1966) [Diagnosis: Spores trilete, azonal, with approx. circular equator; diameter55-65 μ (holotype 61 μ). Exine, 1.5-2 μ thick, with a rather regular but not very dense ornamentation of small echinae (basis diameter 1-2 μ, height max. 1 μ). Trilete rays approx. 2/3 of spore radius, accompanied by indistinct labra (2.5-3 μ). Usually many compression folds. Remarks and comparisons: Because of the strong folding the Y-mark is only occasionally recognizable. The holotype of A. plicatus, however, shows a rather distinct Y-mark. Apiculatasporites spinulistratus (Loose 1932) Ibrahim 1933 differs by the more densely placed echinae of which the height exceeds the diameter.]. It is not extant. It is considered to be a form taxon. Its type specimen is Single grain slide 31-HV-109, a microspore (spore).
