Taxa described in 1833

Coeligena is a genus of South American hummingbirds.

Blumea is a genus of flowering plants of the family Asteraceae.

Anthocharis is a holarctic genus of the butterfly tribe Anthocharini, in the family Pieridae. These are typically small, white-hued butterflies that have colorful marks just inside the tips of the forewings. The tip colors are usually a red-orange hue, hence the name "orange tip". The larvae of these butterfly often consume cruciferous plants containing chemicals called glucosinolates. This genus is characterized by two of the five subcostal veins branching off before the apex of the cell, by the upper radial being only little united with the subcostal, and by the central discocellular being r

Wikstroemia is a genus of 93 species of flowering shrubs and small trees in the mezereon family, Thymelaeaceae. Hawaiian species are known by the common name ‘ākia.

Tristagma is a genus of South American plants in the onion subfamily with the Amaryllis family. It includes 17 species native to Peru, Argentina, and Chile in South America.

Raspailiidae is a family of sponges belonging to the order Axinellida.

Leuconia is a genus of calcareous sponges in the family Baeriidae. It was described by English anatomist and zoologist Robert Edmond Grant in 1833.

Aphelocheirus is a genus of true bugs, the only genus belonging to the family Aphelocheiridae.

Lamproptera is a genus of butterflies in the family Papilionidae and the tribe Leptocircini.

Stemphylium is a genus of fungal plant pathogen.

Apollonias is a genus of flowering plants belonging to the laurel family, Lauraceae. The genus includes from zero to 10 species of evergreen trees and shrubs, depending on circumscription. Recent studies transferred the majority of species to Beilschmiedia. A recent phylogenetic study found that Apollonias barbjuana, native to the Canary Islands and Madeira, is nested in genus Persea, and has been renamed Persea barbujana. Apollonias arnottii, which is endemic to the Western Ghats of India, is considered an unplaced taxon by Plants of the World Online.

Hyphoderma is a genus of crust fungi in the family Hyphodermataceae. It was circumscribed by German botanist Karl Friedrich Wilhelm Wallroth in 1833.

Telenomus is a genus of parasitoid wasps belonging to the subfamily Telenominae. The genus was first described by Alexander Henry Haliday in 1833. Species in this genus parasitise the eggs or immature stages of other insects.

genus of plants

Mathewsia is a genus of flowering plants in the family Brassicaceae. It includes six species native to Peru and northern and central Chile.

Endlicheria is a neotropical plant genus consisting of approximately 60 species, occurring mostly in northern South America and the Amazon region. Most species are medium-sized trees, sometime up to 40 metres in height, but a few species are shrubs. DNA molecular data shows that it is closely related to Rhodostemonodaphne and Ocotea.

Spirostomum is a genus of ciliated protists in the class Heterotrichea. It is known for being very contractile. Having been first identified by Christian Gottfried Ehrenberg in 1834, further research has identified eight additional true morphospecies. This bacterivore genus mainly lives in the sediment deposits at the bottom of various aquatic habitats, and members possess rquA genes that could be responsible for their ability to survive in these hypoxic and anoxic environments. They are identifiable by their relatively (to other ciliates) large tubular/flat vermiform bodies. Their life cycle
