Clavariadelphus is a genus of fungi in the family Clavariadelphaceae in the order Gomphales. Morphologically its members can be described as club fungi with simple, erect and unbranched basidiomata, even if the clavarioid fungi are today not seen as a systematic group. Numbers of described and currently accepted species are constantly rising, this might be connected both to applied new techniques and due to previously understudied areas like China. As of March 2026 there are, depending on the source, either 31, 34 or 35 accepted species currently recognized.

Curvularia is a genus of hyphomycete (mold) fungi which can be pathogens but also act as beneficial partners of many plant species. They are common in soil. Most Curvularia species are found in tropical regions, though a few are found in temperate zones.

Pieriballia is a genus of butterflies in the family Pieridae erected by Alexander Barrett Klots in 1933. Its only species, Pieriballia viardi, the painted white or viardi white, was first described by Jean Baptiste Boisduval in 1836. It is found from Mexico to Bolivia and Paraguay. Strays can be found in southern Texas in the United States. The habitat consists of rainforests and transitional cloud forests.

Tuckermannopsis is a genus of lichen-forming fungi in the family Parmeliaceae. The genus contains about twelve species of foliose (leafy) to somewhat fruticose (bushy) lichens with brownish or greenish thalli. Species in Tuckermannopsis are found primarily in temperate and boreal regions of the Northern Hemisphere, with centres of diversity in western North America and East Asia. Members of the genus are distinguished by their growth form, with reproductive structures largely restricted to the margins of the , and the absence of usnic acid in their upper .

Solpuguna is a genus of solpugid camel spiders, first described by Carl Friedrich Roewer in 1933.

Proxiuber is a genus of sea snails, marine gastropod molluscs in the family Naticidae, the moon shells. The genus is endemic to New Zealand, with fossils dating back to the early Eocene, found in primarily in New Zealand, with one fossil species in Australia.

Pleisticanthoides is a genus of crabs found in the western Pacific Ocean.

Parapleisticantha is a genus of crabs in the family Oregoniidae. It has been found in Japan, the Philippines and the Indian Ocean, but the depth of this genus is not recorded.

Eudentalium is a genus of molluscs belonging to the family Dentaliidae.

Dodecolopoda is a monotypic genus of sea spider (class Pycnogonida) in the family Colossendeidae. The only species in this genus is Dodecolopoda mawsoni. This species is notable as one of only two species of sea spider with six pairs of legs in adults (instead of the usual four leg pairs) and the first such species to be discovered.
