The bird family Petroicidae includes 51 species in 19 genera. All are endemic to Australasia: New Guinea, Australia, New Zealand and numerous Pacific Islands as far east as Samoa. For want of an accurate common name, the family is often called the Australasian robins. Within the family species are known variously as robins, scrub-robins and flyrobins. They are only distantly related to the European robin of Europe, north Africa and western Asia, a member of family Muscicapidae.
The jellynose fishes or tadpole fishes are the small order Ateleopodiformes. This group of ray-finned fish is monotypic, containing a single family Ateleopodidae. It has about a dozen species in four genera, but these enigmatic fishes are in need of taxonomic revision.
The family Cisticolidae is a group of about 160 warblers, small passerine birds found mainly in warmer southern regions of the Old World. They were formerly included within the Old World warbler family Sylviidae.
Gymnophthalmidae is a family of lizards with at least 250 species, sometimes known commonly as spectacled lizards or microteiids. They are called "spectacled" because of their transparent lower eyelids, which allow them to still see with closed eyes. As in most lizards, except geckos, these eyelids are movable. The Alopoglossidae have been recently moved from this family.
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa.
The family Gryllidae contains the subfamilies and genera which entomologists now term true crickets. Having long, whip-like antennae, they belong to the Orthopteran suborder Ensifera, which has been greatly reduced in the last 100 years : taxa such as the spider-crickets and allies, sword-tail crickets, wood or ground crickets and scaly crickets have been elevated to family level. The type genus is Gryllus and the first use of the family name "Gryllidae" was by Walker.
The Acrididae are the predominant family of grasshoppers, comprising some 10,000 of the 11,000 species of the entire suborder Caelifera. The Acrididae are best known because all locusts are of the Acrididae. The subfamily Oedipodinae is sometimes classified as a distinct family Oedipodidae in the superfamily Acridoidea. Acrididae grasshoppers are characterized by relatively short and stout antennae, and tympana on the side of the first abdominal segment.
Ptychopariida is a large, heterogeneous order of trilobite containing some of the most primitive species known. The earliest species occurred in the second half of the Lower Cambrian, and the last species did not survive the Ordovician–Silurian extinction event.
The Aphididae are a very large insect family in the aphid superfamily (Aphidoidea), of the order Hemiptera. These insects suck the sap from plant leaves. Several thousand species are placed in this family, many of which are considered plant/crop pests. They are the family of insects containing most plant virus vectors with the green peach aphid being one of the most prevalent and indiscriminate carriers.
Eremiaphilidae is a small Old World family of praying mantids, based on the type genus Eremiaphila. As part of a major revision of mantid taxonomy, this family now contains the subfamily Tarachodinae, which includes tribes and genera previously placed in the now obsolete Tarachodidae.
Armadillidiidae is a family of woodlice, a terrestrial crustacean group in the order Isopoda. Unlike members of some other woodlice families, members of this family can roll into a ball, an ability they share with the outwardly similar but unrelated pill millipedes and other animals. This ability gives woodlice in this family their common names of pill bugs or roly polies. Other common names include slaters,potato bugs, and doodle bugs. Most species are native to the Mediterranean Basin, while a few species have wider European distributions. The best-known species, Armadillidium vulgare, was introduced to New England in the early 19th century and has become widespread throughout North America.
The Pyxicephalidae are a family of frogs currently found in sub-Saharan Africa. However, in the Eocene, the taxon Thaumastosaurus lived in Europe.
Coreinae is a subfamily in the hemipteran family Coreidae. They have been shown to be paraphyletic with respect to Meropachyinae.
The Crowsoniellidae are a monotypic family of beetles, in the suborder Archostemata. So far, only a single species, Crowsoniella relicta, has been attributed to this family. Known only from three male specimens collected in 1973 in Italy by Roberto Pace. In a degraded pasture, the beetles were found among the roots of a large hawthorn tree, in deep calcareous soil. No other specimens have been found since.
The Cultrinae are one of at least 13 subfamilies of cyprinid fish. It contains ten genera.
The Solanaceae, or nightshades, are a family of flowering plants that ranges from annual and perennial herbs to vines, lianas, epiphytes, shrubs, and trees, and includes a number of agricultural crops, medicinal plants, spices, weeds, and ornamentals. Many members of the family contain potent alkaloids, and some are highly toxic, but many—including tomatoes, potatoes, eggplant, bell and chili peppers—are used as food. The family belongs to the order Solanales, in the asterid group and class Magnoliopsida (dicotyledons). The Solanaceae consists of about 98 genera and some 2,700 species, with a great diversity of habitats, morphology and ecology.
Podismini is a tribe of "spur-throated grasshoppers" in the family Acrididae. This tribe is unlike others in the subfamily Melanoplinae in that a substantial number of genera occur outside the Americas.
Gryllini is a tribe of crickets and typical of the family Gryllidae. Species are terrestrial, carnivorous or omnivorous and can be found in all continenents except Antarctica.
The Hierodulinae are a subfamily of praying mantids, originally used by Brunner von Wattenwyl. It was restored as part of a major revision of mantid taxonomy, and now contains genera previously placed elsewhere in the family Mantidae.
Aepophilus is a monotypic genus of bugs, containing the species Aepophilus bonnairei in the monotypic subfamily Aepophilinae in the monotypic family Aepophilidae of the infraorder Leptopodomorpha. It is found on the Atlantic coast of Europe.
