Augochlora leptoloba is a species of sweat bee in the genus Augochlora and the extinct monotypic subgenus Electraugochlora. [1]
The species is known from a single female specimen, the holotype, currently in the private collection owned by Ettore Morone [2] of Turin, Italy, as number "M-2521", and which was first studied by Dr. Michael S. Engel. Dr. Engel published his type description in the Bulletin of the American Museum of Natural History volume 250 published in 2000. [1] The subgenus name is a combination of the Latin electrum meaning "amber" and Augochlora , the type genus of the tribe Augochlorini. The species name is derived from a combination of the Greek words leptos which means "small" and lobos which means "lobe". [1]
The type specimen is well preserved in early Miocene [3] (Burdigalian stage) [4] Dominican amber from deposits on the island of Hispaniola. [1] The presence of an epistomal sulcus, the groove defining the lateral and dorsal margin of the clypeus, places A. leptoloba within the large genus Augochlora. However, due to the lack of a preoccipital carina, the ridge behind the simple eyes on the top of the head found in the living member of the genus, A. leptoloba was placed in a new subgenus, Electraugochlora. [1] Overall the holotype has a total length, not including antennae, of 8.5 millimetres (0.33 in) and a forewing length of 4.6 millimetres (0.18 in). [1] As a whole the female has a dull metallic green coloration with faint metallic copper highlights to the head, with the region above the mouth being brown. The legs are brown with no discernible highlights, and the wings are hyaline with brown veins. The thorax, like the head, is dull metallic green coloration with faint metallic copper highlights and the underside of the abdomen brown and the upper side brown with metallic green highlights. [1] The legs and terga possess a coating of short gold colored hair. [1]
Halictidae is the second-largest family of bees with nearly 4,500 species. They are commonly called sweat bees, as they are often attracted to perspiration. Halictid species are an extremely diverse group that can vary greatly in appearance. These bees occur all over the world and are found on every continent except Antarctica. Usually dark-colored and often metallic, halictids are found in various sizes, colors and patterns. Several species are all or partly green and a few are red, purple, or blue. A number of them have yellow markings, especially the males, which commonly have yellow faces, a pattern widespread among the various families of bees. The family is one of many with short tongues and is best distinguished by the arcuate basal vein found on the wing. Females in this family tend to be larger than the males. They are the group for which the term 'eusocial' was first coined by entomologist, Suzanne Batra.
Fibla carpenteri is an extinct species of snakefly in the Inocelliidae genus Fibla. F. carpenteri is named in honor of the paleoentomologist Dr Frank Carpenter, for his vast knowledge and interest in Raphidioptera.
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.
Nesagapostemon is an extinct monotypic genus of sweat bee in the Halictidae subfamily Halictinae. At present, it contains the single species Nesagapostemon moronei.
Eickwortapis is an extinct monotypic genus of sweat bee in the Halictidae subfamily Halictinae which contains the single species Eickwortapis dominicana.
Leptofoenus pittfieldae is an extinct species of wasp in the family Pteromalidae. It is known from early Miocene Burdigalian stage Dominican amber deposits on the island of Hispaniola. The species is known from a single 8.8 millimetres (0.35 in) male specimen excavated from the La Toca mine group northeast of Santiago de los Caballeros in 2008 and deposited in the Insect Fossil Collection at the University of Kansas Natural History Museum in Lawrence, Kansas, where it was studied and described by Dr. Michael S. Engel. The species name pittfieldae honors Ms. Morgan Pittfield, niece of the specimen donor.
Leptofoenus is a genus of wasp in the family Pelecinellidae found in South America, Central America, and southern North America. The genus contains five living species and one extinct species known from early Miocene Burdigalian stage Dominican amber deposits on the island of Hispaniola. With body sizes ranging from 11–27 millimetres (0.43–1.06 in) Leptofoenus species are larger than nearly all other species in Chalcidoidea. The genus bears a notable resemblance to the wasp families Pelecinidae, Gasteruptiidae, and Stephanidae.
Termitaradus mitnicki is an extinct species of true bug in the family Termitaphididae known only from early Miocene Burdigalian stage Dominican amber deposits on the island of Hispaniola.
Roystonea palaea is an extinct species of palm known from fossil flowers found in the early Miocene Burdigalian stage Dominican amber deposits on the island of Hispaniola. The species is known from a single staminate flower and a single pistillate flower both preserved in the same piece of amber. The amber specimen bearing the holotype and paratype is currently deposited in the collections of the Oregon State University in Corvallis, Oregon, as number "Sd–9–101", where it was studied and described by George Poinar. Poinar published his 2002 type description for R. palaea in the Botanical Journal of the Linnean Society, Volume 139. The species' second name is taken from the Greek word palaios meaning "ancient". The amber specimen bearing the flowers was excavated from the La Toca mine northeast of Santiago de los Caballeros, Dominican Republic.
Protosialis casca is an extinct species of alderfly in the Sialidae subfamily Sialinae. The species is solely known from the early Miocene, Burdigalian stage, Dominican amber deposits on the island of Hispaniola. Protosialis casca is one of only two known alderfly species present in the West Indies, the only other species is the living Protosialis bifasciata native to Cuba.
Aureofungus is an extinct monotypic genus of gilled fungus in the order Agaricales. At present it contains the single species Aureofungus yaniguaensis.
Protomycena is an extinct monotypic genus of gilled fungus in the family Mycenaceae, of order Agaricales. At present it contains the single species Protomycena electra, known from a single specimen collected in an amber mine in the Cordillera Septentrional area of the Dominican Republic. The fruit body of the fungus has a convex cap that is 5 mm (0.2 in) in diameter, with distantly spaced gills on the underside. The curved stipe is smooth and cylindrical, measuring 0.75 mm (0.030 in) thick by 10 mm (0.39 in) long, and lacks a ring. It resembles extant species of the genus Mycena. Protomycena is one of only five known agaric fungus species known in the fossil record and the second to be described from Dominican amber.
Tainosia is an extinct monotypic genus of planthopper in the Nogodinidae subfamily Nogodininae and at present, it contains the single species Tainosia quisqueyae. The genus is solely known from the early Miocene, Burdigalian stage, Dominican amber deposits on the island of Hispaniola.

Anthophorula (Anthophorula) persephone is an extinct species of bee in the subfamily Apinae known from a pair of possibly Miocene fossils 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.
Augochlorella aurata is a primitively eusocial species of sweat bee in the family Halictidae. It is one of three species of Augochlorella found east of the Rocky Mountains in North America. The body is a brilliant green metallic color, diffused to varying extents with a copper, red, or yellow color. A. aurata is a generalist pollen feeder and likely an important pollinator for some horticultural crops. A common name is golden green sweat bee.
