Description
Plagiogramma minor (W.Gregory) Chunlian Li, Ashworth & Witkowski Figs 85, 86
Basionym: Denticula minor W.Gregory
Ref. illus.: Kaczmarska et al. 2017, p. 27, figs 13A–D.
Samples: GU52O-4, GU52X-5 (biofilm on calcareous sand)
Dimensions: Length 11–12 µm, width 5 µm; striae 17 in 10 µm
Diagnostics: rhomboidal valves with central elevation and two elevated apical pore fields; large flaps on the four most-apical spines.
Comments: Kaczmarska et al. (2017) compared their specimens to similar species and concluded that there was no match. Our specimens are very close to their fig. 13A. In their nomenclatural note, Kaczmarska et al. claimed that the correct epithet is minus, since Dimeregramma is a neuter noun, and Li et al. (2020, p. 13) used this transferring the species to Plagiogramma (also neuter). However, minus is an adverb and the correct adjective here is minor, which has the same ending across all genders in the nominative singular (Stearn 1973), as used by Gregory (1857) in the basionym.
