Pareodinia ceratophora subsp. pachycera

"subsp. pachycera" (Sarjeant, 1959, p.337, pl.13, fig.10; text-fig.5a) Lentin and Williams, 1973, p.108.  Holotype: Sarjeant, 1959, pl.13, fig.10; text-fig.5a.  Originally Pareodinia ceratophora var. pachycera, subsequently Pareodinia ceratophora subsp. pachycera.  Taxonomic senior synonym: Pareodinia ceratophora subsp. ceratophora (as Pareodinia ceratophora var. ceratophora), according to Below (1990, p.65).  The derivation of the name was not stated in the protologue.  Since Principle 5 of the I.C.N. states that taxa names are to be treated as Latin and since compound epithets are conventionally treated as adjectives, the epithet should be rendered as "pachycera" in agreement with the feminine gender of the generic name.  Age: early Callovian.

Parent: Pareodinia ceratophora
