Habrotrocha is a genus of bdelloid rotifers.
Late Eocene fossils of Habrotrocha in Dominican amber are among the oldest known fossil rotiferans. [2]
The rotifers, commonly called wheel animals or wheel animalcules, make up a phylum of microscopic and near-microscopic pseudocoelomate animals.
Bdelloidea is a class of rotifers found in freshwater habitats all over the world. There are over 450 described species of bdelloid rotifers, distinguished from each other mainly on the basis of morphology. The main characteristics that distinguish bdelloids from related groups of rotifers are exclusively parthenogenetic reproduction and the ability to survive in dry, harsh environments by entering a state of desiccation-induced dormancy (anhydrobiosis) at any life stage. They are often referred to as "ancient asexuals" due to their unique asexual history that spans back to over 25 million years ago through fossil evidence. Bdelloid rotifers are microscopic organisms, typically between 150 and 700 µm in length. Most are slightly too small to be seen with the naked eye, but appear as tiny white dots through even a weak hand lens, especially in bright light. In June 2021, biologists reported the restoration of bdelloid rotifers after being frozen for 24,000 years in the Siberian permafrost.
Dominican amber is amber from the Dominican Republic derived from resin of the extinct tree Hymenaea protera.
Rotaria is a genus of asexual, microscopic animal known as a bdelloid rotifer. Analysis published in 2007 of morphology and DNA sequence data of species form the genus confirmed that despite their asexual mechanism of reproduction, two fundamental properties of species, independent evolution and ecological divergence by natural selection occurred. This demonstrates that sex is not a necessary condition for speciation.
David A. Grimaldi is an entomologist and Curator of Invertebrate Zoology at the American Museum of Natural History in New York. He received his graduate training at Cornell University, where he earned his doctorate in Entomology in 1986. Dr. Grimaldi is an authority in many fields of insect systematics, paleontology, and evolutionary biology.
Habrotrocha rosa is a bdelloid rotifer that has been found in leaf litter, soil, and moss in Europe and New Zealand and also in North America within the pitchers of Sarracenia purpurea, the purple pitcher plant. It is one of many species that make up the inquiline community that thrives within the water-retaining pitcher-shaped leaves of S. purpurea.
Gnathifera is a clade of generally small spiralians characterized by complex jaws made of chitin. It comprises the phyla Gnathostomulida, Rotifera, Micrognathozoa, and Chaetognatha. It may also include the Cycliophora.
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.
Syndesus ambericus is an extinct species of stag beetles in the subfamily Syndesinae known from a single possibly Miocene fossil found on Hispaniola. S. ambericus is the first species of stag beetle to have been described from fossils found in Dominican amber and is one of four species from amber, and the only stag beetle species known from the Caribbean.
Adineta ricciae is a species of freshwater rotifers in the family Adinetidae. It was first described in 2005 after being discovered by chance in dry mud beside a billabong in Australia. It is used as a model organism as it is easy to keep in culture.
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.
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.
Apterostigma electropilosum is an extinct species of ant in the subfamily Myrmicinae known from a single possibly Miocene fossil found on Hispaniola. A. electropilosum is one of only two species of the ant genus Apterostigma and one of five attini species to have been described from fossils found in Dominican amber.
Apterostigma eowilsoni is an extinct species of ant in the subfamily Myrmicinae known from a single possibly Miocene fossil found on Hispaniola. A. eowilsoni is one of only two species of the ant genus Apterostigma and one of five attini species of to have been described from fossils found in Dominican amber.
Azteca alpha is an extinct species of ant in the subfamily Dolichoderinae known from possibly Miocene fossils found on Hispaniola. A. alpha is one of only two species in the genus Azteca to have been described from fossils, both found in Dominican amber. It is the host for a fossil nematode, and has been preserved with scale insects.
Azteca eumeces is an extinct species of ant in the subfamily Dolichoderinae known from possibly Miocene fossils found on Hispaniola. A. eumeces is one of only two species in the ant genus Azteca to have been described from fossils, both found in Dominican amber.
Philodina acuticornis is a species of freshwater bdelloid rotifers.
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.
