Ceanothus is a genus of about 50–60 species of nitrogen-fixing shrubs and small trees in the buckthorn family (Rhamnaceae). Common names for members of this genus are buckbrush, California lilac, soap bush, or just ceanothus. "Ceanothus" comes from Ancient Greek: κεάνωθος (keanōthos), which was applied by Theophrastus to an Old World plant believed to be Cirsium arvense.
Coral snakes are a large group of elapid snakes that can be divided into two distinct groups, the Old World coral snakes and New World coral snakes. There are 16 species of Old World coral snakes, in three genera, and over 65 recognized species of New World coral snakes, in two genera. Genetic studies have found that the most basal lineages have origins in Asia, suggesting that the group originated in the Old World. While new world species of both genera are venomous, their bites are seldom lethal; only two confirmed fatalities have been documented in the past 100 years from the genus Micrurus. Meanwhile, snakes of the genus Micruroides have never caused a medically significant bite.
Micrurus is a genus of venomous coral snakes of the family Elapidae.
Huayqueriana is an extinct genus of South American litoptern, related to Macrauchenia, and belonging to the same family, Macraucheniidae. It was formerly known as Macrauchenidia latidens, described in 1939 by Cabrera, but redefined as Huayqueriana in 2016 based on the earlier name convention of Rovereto 1914. The genus is named after the Huayquerías Formation and the eponymous Huayquerian South American land mammal age defined at the formation.
Carnivoramorpha is a clade of placental mammals that includes the modern order Carnivora and its extinct stem-relatives.
Pseudagrion is the largest genus of damselfly in the family Coenagrionidae, with over 140 species. Its range includes most of Africa, much of Asia, and Australia. Africa holds most of the diversity with almost 100 species. It has occupied most of the freshwater habitats in its range, and dominates damselfly communities in habitats as different as desert pools, equatorial rainforests and montane streams.
Neotragus is a genus of dwarf antelope, native to Africa. The genus includes only a single species without any dispute, namely Neotragus pygmaeus. Neotragus pygmaeus is the smallest antelope in the world, they usually weigh around 5 to 7 pounds. This animal lives in conditions that are warm and moist, they are found in the tropical forests of Western Africa. The Neotragus pygmaeus diet consists of high nutrients food sources, such as leaves, flowers, plants, fruits, and the growing tips of shoots. Recent nucleic acid studies now suggest that the other two species formerly included in the genus are not closely related, and should be assigned to the genus Nesotragus. Members of the Nesotragus genus are the only surviving members of the subfamily Nesotraginae or tribe Nesotragini and are more closely related to the impala, while the royal antelope is still a member of the subfamily Antilopinae or tribe Antilopini.
Pachycondyla is a ponerine genus of ants found in the Neotropics.
The subfamily Aphaeninae is a group of hemipteran insects, especially abundant and diverse in the tropics. They belong to the Fulgoridae (fulgorids), though they are not among the better-known members of that family that are called "lantern bugs" or "lanternflies". In 2009, the first molecular analysis of the Fulgoridae challenged the existing structure of eight currently recognized subfamilies and eleven tribes.
Cercopidae are the largest family of Cercopoidea, a xylem-feeding insect group, commonly called froghoppers or spittlebugs. They belong to the hemipteran suborder Auchenorrhyncha.
Pterygotrigla is a genus of genus of marine ray-finned fishes belonging to the family Triglidae, the gurnards and sea robins, one of two genera belonging to the subfamily Pterygotriglinae. These gurnards are found in the Indian and Pacific oceans.
Chydaeus is a genus of beetles in the family Carabidae. Members of this genus are distributed mainly over mountainous regions of southeastern Asia, from the Himalayas and China to the Sunda Islands; however, three species are known from New Guinea and one from Australia.
Chondrilla is a genus of sea sponges belonging to the family Chondrillidae.
Parachaetolopha is a genus of moths in the family Geometridae. Most species were previously included in the genus Chaetolopha.
Rossellidae is a family of glass sponges belonging to the order Lyssacinosa. The family has a cosmopolitan distribution and is found at a large range of depths.
Hebius is a genus of snakes in the family Colubridae.
Trachelas is a genus of araneomorph spiders originally placed with the Trachelidae, and later moved to the Corinnidae.
Protolestes is a genus of flatwings in the damselfly order Odonata. There are about eight described species in Protolestes.
Polymorphis is an extinct genus of litopterns belonging to the family Macraucheniidae. It lived during the Middle Eocene of Argentina.
