Fundamental reassessment of the taxonomy of five Normapolles pollen genera
Résumé
Diagnoses of the Normapolles pollen genera Hungaropollis,
Krutzschipollis, Longanulipollis, Oculopollis and Trudopollis and
56 of their species are emended and many specimens illustrated in
order to provide a basis for more successful and consistent identification
than has been possible hitherto. These taxa were recovered
from palynological preparations of selected samples from Late Cretaceous
deposits in Europe, southern Sweden and eastern USA.
As indicated on an accompanying range chart the majority are encountered
in Santonian and/or Campanian deposits. Eleven of the
species described have been transferred from other genera and are
therefore in new combinations, namely: Hungaropollis granulatus
(Kedves et Herngreen), Longanulipollis coronatiformis (Góczán
et Siegl-Farkas), L. orbicularis (Góczán), L. ornatus (Kedves et
Diniz), L. parvoculus (Góczán), L. skarbyae (Kedves et Diniz),
Oculopollis artifex (Weyland et Krieger), O. rector (Pflug), O.
triceps (Skarby), Trudopollis cuneolis (Góczán et Siegl-Farkas),
and T. spinulosus (Skarby). Six are new: Hungaropollis pinguis,
Krutzschipollis cucullus, K. immanis, Longanulipollis amabilis, L.
lobus and Oculopollis viriosus. Thirteen genera are regarded as
synonyms of Hungaropollis (Aveiropollenites and Romeinipollenites),
Longanulipollis (Coronatipollis, Intercalaripollis, Portaepollenites
and Verruoculopollis), Oculopollis (Druggipollenites, Pseudoculopollis
and Semioculopollis) and Trudopollis (Cuneipollis,
Felderipollenites, Hofkeripollenites and Kriegeripollenites) respectively.
As a result of some of these nomenclatural changes 14 other
species are in new generic combinations but are not otherwise considered.
Seven morphotypes are identified in open nomenclature
and four placed in comparison.
