Material. Samples Pb-9343, Pb-9340, and Pb- 9334, Palynology Laboratory, IGLUNAM.
Description. Monad pollen, isopolar, radiosymmetric, amb triangular. Triporate, annulate, annulus 7 P m thick, pores aspidate with granulate structure. Exine tectate, 1–1.6 P m thick, psilate, with microreticular endopattern.
Dimensions. Equatorial diameter 24–38.4 µm, four specimens measured.
Comparisons. Corsinipollenites . sp. 1 (in this paper) shows smaller dimensions and more aspidate pores compared to Corsinipollenites sp. 2 and Corsinipollenites sp. 3 of the Cuayuca assemblage. Corsinipollenites sp.1 has a more protruding pore and annuli thicker than those reported by Jaramillo and Dilcher (2001) which have annulus 2 P m thick, as well as that recovered from middle Eocene of Florida, with annulus 2–4 P m wide ( Jarzen and Klug, 2010).
Other occurrences. In Mexico, the genus is reported to be from late Eocene to early Oligocene Pie de Vaca Formation ( Martínez-Hernández and Ramírez-Arriaga, 1999); Oligocene San Gregorio Formation (Martínez-Hernández and Ramírez-Arriaga, 2006). Jaramillo and Dilcher (2001) reported Corsinipollenites in the Paleocene of Colombia; it is also mentioned in the Paleocene of Merida Andes, western Venezuela ( Pocknall and Jarzen, 2009) and in the early to middle Eocene from Pine Island, Florida ( Jarzen and Klug, 2010) and Oligocene of Germany ( Thiergart, 1940). More data on the distribution of this genus in the U.S.A. and northern South America is in Jarzen and Klug (2010).
