Riodinidae is the family of metalmark butterflies. The common name "metalmarks" refers to the small, metallic-looking spots commonly found on their wings. The 1,532 species are placed in 146 genera. Although mostly Neotropical in distribution, the family is also represented both in the Nearctic, Palearctic, Australasian (Dicallaneura), Afrotropic, and Indomalayan realms.
Butterfly evolution is the origin and diversification of butterflies through geologic time and over a large portion of the Earth's surface. The earliest known butterfly fossils are from the mid Eocene epoch, between 40-50 million years ago. Their development is closely linked to the evolution of flowering plants, since both adult butterflies and caterpillars feed on flowering plants. Of the 220,000 species of Lepidoptera, about 45,000 species are butterflies, which probably evolved from moths. Butterflies are found throughout the world, except in Antarctica, and are especially numerous in the tropics; they fall into eight different families.
Neocorynura electra is an extinct species of sweat bee in the Halictidae genus Neocorynura.
Oligochlora is an extinct genus of sweat bee in the Halictidae subfamily Halictinae. The genus currently contains six species, all of which are known from the early Miocene Burdigalian stage Dominican amber deposits on the island of Hispaniola.
Paleoleishmania is an extinct genus of kinetoplastids, a monophyletic group of unicellular parasitic flagellate protozoa. At present it is placed in the family Trypanosomatidae. The genus contains two species, the type species Paleoleishmania proterus and the later described Paleoleishmania neotropicum.
The Lepidoptera fossil record encompasses all butterflies and moths that lived before recorded history. The fossil record for Lepidoptera is lacking in comparison to other winged species, and tending not to be as common as some other insects in the habitats that are most conducive to fossilization, such as lakes and ponds, and their juvenile stage has only the head capsule as a hard part that might be preserved. Yet there are fossils, some preserved in amber and some in very fine sediments. Leaf mines are also seen in fossil leaves, although the interpretation of them is tricky. Putative fossil stem group representatives of Amphiesmenoptera are known from the Triassic.
Vetufebrus is an extinct genus of haemospororida in the family Plasmodiidae. At the time of its description the new genus comprised a single species Vetufebrus ovatus known from a single Miocene Dominican amber fossil found on Hispaniola. V. ovatus was vectored by Enischnomyia stegosoma, the first fossil streblid bat fly described from a fossil, and the only member of the subfamily Nycterophiliinae described from Hispaniola. V. ovatus is the first instance of a Streblidae bat fly as a host for a malarial parasite.
Lithopsyche is a genus of fossil butterflies known from Oligocene-aged strata of the Isle of Wight, England. The sole specimen is too incomplete to allow a certain assignment of a family, but it was placed on its description as a geometrid and more recently in the Riodininae.
Termitaradus dominicanus is an extinct species of termite bug in the family Termitaphididae known from a Miocene fossil found on Hispaniola. T. dominicanus is the third species in the genus Termitaradus to have been described from fossils found in Dominican amber after Termitaradus avitinquilinus and Termitaradus mitnicki.
Termitaradus protera is an extinct species of termite bug in the family Termitaphididae known from several Late Oligocene to Early Miocene fossils found in Mexico. T. protera is the only species in the extant genus Termitaradus to have been described from fossils found in Mexican amber and is one of four species from new world amber; the others are Termitaradus avitinquilinus, Termitaradus dominicanus and Termitaradus mitnicki. T. protera was also the first termite bug described from the fossil record.
Termitaradus avitinquilinus is an extinct species of termite bug in the family Termitaphididae known from several possibly Miocene fossils found in the Dominican Republic. T. avitinquilinus is the first species in the genus Termitaradus to have been described from fossils found in Dominican amber and is one of four species from New World amber, the others being Termitaradus protera, Termitaradus dominicanus and Termitaradus mitnicki.
Acanthostichus hispaniolicus is an extinct species of ant in the subfamily Dorylinae known from a group of possibly Miocene fossils found on the Caribbean island of Hispaniola. A. hispaniolicus is the first species of the ant genus Acanthostichus to have been described from fossils found in Dominican amber, and is the only species of Acanthostichus found in the West Indies.
Acropyga glaesaria is an extinct species of ant in the subfamily Formicinae known from a group of possibly Miocene fossils found on Hispaniola. A. glaesaria is the first species of the ant genus Acropyga to have been described from fossils found in Dominican amber and is the one of several species of Acropyga found in the West Indies. As with other members of the genus, A. glaesaria was most likely trophobiotic.
Acanthognathus poinari is an extinct species of ant in the subfamily Myrmicinae known from a single possibly Miocene fossil found on Hispaniola. A. poinari is the first species of the ant genus Acanthognathus to have been described from fossils found in Dominican amber and is one of several species of Acanthognathus found in the Greater Antillas.
Anochetus brevidentatus is an extinct species of ant in the subfamily Ponerinae known from two possibly Miocene fossils found on Hispaniola. A. ambiguus is one of eight species in the ant genus Anochetus to have been described from fossils found in Dominican amber and is one of a number of Anochetus species found in the Greater Antillies.
Anochetus corayi is an extinct species of ant in the subfamily Ponerinae known from one possibly Miocene fossil found on Hispaniola. A. corayi is one of eight species in the ant genus Anochetus to have been described from fossils found in Dominican amber and is one of a number of Anochetus species found in the Greater Antillies.
Anochetus lucidus is an extinct species of ant in the subfamily Ponerinae known from two possibly Miocene fossils found on Hispaniola. A. lucidus is one of eight species in the ant genus Anochetus to have been described from fossils found in Dominican amber and is one of a number of Anochetus species found in the Greater Antillies.
Parastemmiulus is an extinct genus of millipede in the family Stemmiulidae known from a fossil found in Mexico. There is one described species in the genus, Parastemmiulus elektron. The species is one of three millipedes described from Mexican amber, and the oldest Stemmiulidae fossil species as of 2013.
Enischnomyia is an extinct genus of bat fly in the family Streblidae. At the time of its description the new genus comprised a single species, Enischnomyia stegosoma, known from a single Miocene fossil found on Hispaniola. E. stegosoma was the first fossil streblid bat fly described from a fossil, and the only member of the subfamily Nycterophiliinae described from Hispaniola. The species is host for the plasmodiid Vetufebrus ovatus preserved in its salivary glands and midgut.
Styx is a monotypic genus of butterflies in the metalmark family Riodinidae. It consists of one species, Styx infernalis, described by Otto Staudinger in 1875. It is endemic to Peru, where it inhabits tropical montane cloud forests between the elevations of 1000-1600 meters.
