Spathantheum is a genus of flowering plants in the family Araceae.
 The genus contains two species, "Spathantheum fallax" and "Spathantheum orbignyanum".
 "Spathantheum" is believed to be closely related to "Spathicarpa".
 The genus is endemic to the Andes of Peru, Bolivia, and northern Argentina and is found growing in grasslands in rocky soil.
Ameliella is a genus of lichenized fungi in the Lecanoraceae family.
 Described in 2008, the genus contains two species, "A. andreaeicola" and "A. grisea", that were collected from high elevations in the Scottish Highlands.
 The two species have also been found in single instances in British Columbia and Northern Norway.
 The generic name is derived from the Greek "ameleo", meaning "neglected" or "overlooked"; it was originally intended to be "Amelia", which is also the first name of the daughter of one of the authors, but this name had previously been used for another genus and was therefore ineligible for use according to the rules of mycological nomenclature.
 "Ameliella" appears to have some similarity with the lichen genus "Miriquidica".
Oedistoma is a genus of longbill in the bird family Melanocharitidae (berrypeckers and longbills).
 The genus, like the family, is endemic to New Guinea.
 The genus contains two species, both of which are sometimes placed in the genus "Toxorhamphus".
Macrotus is a genus of bats in the Neotropical family Phyllostomidae.
 This genus contains two species, "Macrotus californicus" commonly known as California Leaf-nosed Bat and "Macrotus waterhousii" commonly known as Mexican or Waterhouse's Leaf-nosed Bat.
 The range of this family includes the warmer parts of the southwestern United States, Mexico, Central and South America, and the Bahama Islands.
 Characteristic for the genus are large ears and the name giving triangular skin flap above the nose, the "leaf".
 The California Leaf-nosed Bat inhabits the arid deserts of the southwestern United States as far north as Nevada, south to Baja California and Sonora, Mexico.
 The California Leaf-nosed Bat is of medium size, with a total length between 9 and 11 cm Its most distinctive features are the large ears, connected across the forehead.
 The body is pale grayish brown dorsally with whitish under parts.
 The pelage (fur) on the body is silky, the hairs on the back about 8 mm, on the front about 6 mm long.
 The posterior base of the ears are covered with hair of a woolly texture while the interior surface and most of the anterior border shows scattered long hairs.
 The flight membranes are thin and delicate; the wings are broad and the tail is slightly shorter that the long hind limbs and extends several millimeters beyond the uropatagium (see Bat).
 "Macrotus waterhousii" is also a big eared Bat which has ranges from Sonora to Hidalgo Mexico, south to Guatemala and the Greater Antilles (excluding Puerto Rico) and Bahamas.
 This species roosts primarily in caves, but also in mines and buildings.
 This species is also insectivorous (see insectivore), primarily consuming insects of the order Lepidoptera and Orthoptera.
 The mating and parturition times of M. "waterhousii" vary from island to island with 4–5 months gestation.
Mirocaris is a genus of shrimp associated with hydrothermal vents. Sometimes considered the only genus of the family Mirocarididae, "Mirocaris" is usually placed in the family Alvinocarididae.
 The genus contains two species, "M. fortunata" and "M. indica"; the former species "M. keldyshi" is now considered synonymous with "M. fortunata".
 The two species are found in different oceans, and can be distinguished by the pattern of setation on the claw of the first pereiopod.
Disanthus is a genus containing two species of flowering plants in the family Hamamelidaceae.
 The type species, "Disanthus cercidifolius", was the only known species until 2017, when a second species, "Disanthus ovatifolius" was described.
Bombyx is the genus of true silkmoths or mulberry silkmoths of the family Bombycidae.
 For a few thousand years, people only recognised two species, but then several other less important species were discovered, and the genus contains two tested hybrid species, a semi-natural cross between a female Bombyx mori and a male Bombyx mandarina, and another hybrid the other way around from the first.
Hyphodontiella is a genus of two species of wood-inhabiting corticioid fungi.
 The genus contains two species found in Nordic countries.
 "Hyphodontiella" was circumscribed by Swedish mycologist Åke Strid in 1975.
 Originally classified in the family Corticiaceae along with most other corticioid fungi, it was moved to the Clavariaceae in 2007 .
Leucospermum (Pincushion, Pincushion Protea or Leucospermum) is a genus of about 50 species of flowering plants in the family Proteaceae, native to Zimbabwe and South Africa, where they occupy a variety of habitats, including scrub, forest, and mountain slopes.
Peltops is a genus of bird in the family Artamidae.
 The genus contains two species endemic to the island of New Guinea.
 The genus was once placed with the monarch flycatchers, but molecular and morphometric studies place it closer to the butcherbirds, possibly as a sister taxon to this group.
 The genus is named for the Greek "pelte" meaning small shield and "ops" meaning face.
 The species have also had the common name of shieldbill.
