Parastremma is a genus of characins endemic to western Colombia. There are currently three species in this genus.
The Thomisidae are a family of spiders, including about 170 genera and over 2,100 species. The common name crab spider is often linked to species in this family, but is also applied loosely to many other families of spiders. Many members of this family are also known as flower spiders or flower crab spiders.
Wolf spiders are members of the family Lycosidae, named for their robust and agile hunting skills and excellent eyesight. They live mostly in solitude, hunt alone, and usually do not spin webs. Some are opportunistic hunters, pouncing upon prey as they find it or chasing it over short distances; others wait for passing prey in or near the mouth of a burrow. Wolf spiders resemble nursery web spiders, but wolf spiders carry their egg sacs by attaching them to their spinnerets, while the Pisauridae carry their egg sacs with their chelicerae and pedipalps. Two of the wolf spider's eight eyes are large and prominent; this distinguishes them from nursery web spiders, whose eyes are all of roughly equal size. This can also help distinguish them from the similar-looking grass spiders.
Latrodectus is a broadly distributed genus of spiders with several species that are commonly known as the true widows. This group is composed of those often loosely called black widow spiders, brown widow spiders, and similar spiders. However, the diversity of species is much greater. A member of the family Theridiidae, this genus contains 34 species, which include several North American "black widows". Besides these, North America also has the red widow Latrodectus bishopi and the brown widow Latrodectus geometricus, which, in addition to North America, has a much wider geographic distribution. Elsewhere, others include the European black widow, the Australian redback spider and the closely related New Zealand katipō, several different species in Southern Africa that can be called button spiders, and the South American black-widow spiders. Species vary widely in size. In most cases, the females are dark-coloured and can be readily identified by reddish markings on the central underside (ventral) abdomen, which are often hourglass-shaped.
Linyphiidae, spiders commonly known as sheet weavers, or money spiders is a family of very small spiders comprising 4706 described species in 620 genera worldwide. This makes Linyphiidae the second largest family of spiders after the Salticidae. The family is poorly understood due to their small body size and wide distribution; new genera and species are still being discovered throughout the world. The newest such genus is Himalafurca from Nepal, formally described in April 2021 by Tanasevitch. Since it is so difficult to identify such tiny spiders, there are regular changes in taxonomy as species are combined or divided.
Gasteracantha is a genus of orb-weaver spiders first named by Carl Jakob Sundevall in 1833. Species of the genus are known as spiny-backed orb-weavers, spiny orb-weavers, or spiny spiders. The females of most species are brightly colored with six prominent spines on their broad, hardened, shell-like abdomens. The name Gasteracantha is derived from the Greek gaster (γαστήρ), meaning "belly, abdomen", and akantha (άκανθα), meaning "thorn, spine". Spiny-backed orb-weavers are sometimes colloquially called "crab spiders" because of their shape, but they are not closely related to the true crab spiders. Other colloquial names for certain species include thorn spider, star spider, kite spider, or jewel spider.
Xenorhina is a genus of microhylid frogs. The genus is endemic to New Guinea. They are sometimes known as the snouted frogs or fanged frogs, the latter referring to the now-synonymized genus Xenobatrachus.
Orchestia is a genus of amphipods in the family Talitridae. Species in Orchestia are parasitized by the Filozoan species Txikispora philomaios.
Helogenes is a genus of whale catfish found in tropical South America.
Schultzichthys is a genus of pencil catfishes native to South America.
Brycon is a genus of fish in the family Bryconidae and order Characiformes found in freshwater habitats in Central and South America, ranging from southern Mexico to northern Argentina. Despite not being closely related to true trout, they are sometimes called South American trout. Members of the genus may be referred to by a number of other different common names in various languages. They reach a maximum length of 11.9–79.5 cm (4.7–31.3 in) depending on the species involved. Some species perform seasonal breeding migrations.
The Metopininae are a subfamily of flies in the family Phoridae.
Dolichancistrus is a genus of suckermouth armored catfishes native to South America.
Synema is a genus of spider in the family Thomisidae, found in most parts of the world.
Xerolycosa is a small genus of wolf spiders in the family Lycosidae, subfamily Evippinae, consisting of three species which have a Palearctic distribution and one with an Afro-tropical distribution.
Artoria is a genus of spiders in the family Lycosidae. It was first described in 1877 by Tamerlan Thorell, and the type species is Artoria parvula. In 1960, Roewer erected the genera Artoriella and Trabeola. However, in 2002, Volker Framenau reviewed Artoria and synonymised both these genera with Artoria.
Geolycosa is a genus of wolf spiders first described in 1904.
Micrargus is a genus of dwarf spiders that was first described by Friedrich Dahl in 1886.
The 1960 North Dakota gubernatorial election was held on November 8, 1960. Democratic nominee William L. Guy defeated Republican nominee and Lieutenant Governor Clarence P. Dahl with 49.44% of the vote.
Harpiniopsis is a genus of crustaceans in the family Phoxocephalidae. Species of this genus are found throughout the world. It was first described by Knud Stephensen in 1925.
