Diagnosis
ReferenceDiagnosis
T. Van der Hammen and C. Garcia de Mutis 1966The holotype (Slide V-I-70, Col. S.G.N., Santa Rosita, Maestrichtian, base of Zone C) is tricolpate and micro-reticulate. The reticulum is finer towards the colpi, and has a ± psilate zone bordering the colpi; but at the ends it is lacking. Polar area small. Size ± 20 μ, in polar view. The specimens from the Paleocene exactly correspond with the description; the size in polar view can be up to 25 μ. Has been encountered in the samples RL-7 (near the limit of Zones A and B), RL-13 (in Zone C) and Cat.-472 (in Zone B).
