A new species of Proceroplatus Edwards (Diptera: Keroplatidae) in Miocene amber from the Dominican Republic.

Keroplatid fungus gnats (Diptera: Keroplatidae) were hitherto known from the Caribbean island of Hispaniola from a single named species in Miocene amber from the Dominican Republic. Here we describe the new fossil species Proceroplatus preziosii Evenhuis & Penney based on a mature male specimen, which differs markedly from both fossil and extant taxa in the structure of its gonostyli and U-shaped wing pattern. We also document the first record of extant Keroplatidae, Proceroplatus pictipennis (Williston), from Hispaniola.

A new fossil cricket of the genus Proanaxipha in Miocene amber from the Dominican Republic (Orthoptera, Gryllidae, Pentacentrinae).

A new species of the cricket genus Proanaxipha Vickery & Poinar (Orthoptera: Gryllidae: Pentacentrinae) from Early Miocene Dominican amber is described and illustrated. Proanaxipha madgesuttonaesp. n.

Ancient Ephemeroptera-Collembola symbiosis fossilized in amber predicts contemporary phoretic associations.

X-ray computed tomography is used to identify a unique example of fossilized phoresy in 16 million-year-old Miocene Dominican amber involving a springtail being transported by a mayfly. It represents the first evidence (fossil or extant) of phoresy in adult Ephemeroptera and only the second record in Collembola (the first is also preserved in amber). This is the first record of Collembola using winged insects for dispersal.
