spec. Pierella  (teste Warren 2015)

Nymphalidae  : Satyrinae  : Haeterini  : Pierella  .

Colombia, Santander Department, copal; Holocene/Pleistocene 

Depository: FMNH.

The specimen is a remarkably well-preserved fossil, so much that A.D. Warren (pers. comm.), who saw the specimen in July, 2015, thought it was a fake. According to Warren it exactly resembles the extant Pierella helvina Hewitson  ( Nymphalidae  : Satyrinae  ), which is distributed from Nicaragua to Ecuador with Colombia being the type locality, except for the reddish color of the extant species. However, the fossil has not yet been studied in detail. In view of the young age of the fossil it is of little interest for calibration of the molecular clock, except for the evolution within the genus Pierella  .
