Taxa described in 1873

The Cheirogaleidae are the family of strepsirrhine primates containing the various dwarf and mouse lemurs. Like all other lemurs, cheirogaleids live exclusively on the island of Madagascar.

Amborella is a monotypic genus of understory shrubs or small trees endemic to the main island, Grande Terre, of New Caledonia in the southwest Pacific Ocean. The genus is the only member of the family Amborellaceae and the order Amborellales and contains a single species, Amborella trichopoda. Amborella is of great interest to plant systematists because molecular phylogenetic analyses consistently place it as the sister group to all other flowering plants; as a result, it is critical for understanding angiosperm evolution. It is understood to be the most basal extant flowering plant, and is on

Bhutanitis is a genus of swallowtail butterflies that contains four species.

Aphrissa is a genus of butterflies in the family Pieridae found in Central and South America.

Pupisoma is a genus of minute, air-breathing land snails, terrestrial pulmonate gastropod molluscs or micromollusks in the family Valloniidae.

Circinella is a genus of fungi belonging to the family Syncephalastraceae. It was first described by Philippe Édouard Léon Van Tieghem & (Alexandre Alexis) George Le Monnier in 1873.

Lichinella is a genus of lichen-forming fungi in the family Lichinellaceae. The genus is morphologically diverse, including species that form crusts, small scales, or tiny shrub-like tufts. Its members grow on rock surfaces and in biological soil crusts, mainly in warm-temperate to arid tropical regions worldwide. It was described by William Nylander in 1873, and was placed in the newly erected family Lichinellaceae following a 2024 molecular reclassification of the Lichinomycetes.

Steinia is a genus of lichen-forming fungi in the family Aphanopsidaceae. The genus was established in 1873 by Gustav Wilhelm Körber and contains three recognised species. These lichens grow on disturbed soil and form very thin, powdery crusts that are often barely visible to the naked eye. They produce small, dark brown to black fruiting bodies that contain unusually large numbers of ascospores—up to 16 in each spore-bearing structure.

Tentegia is a genus of weevils native to Australia. It is the only genus of weevils known to engage in coprophagy.

Ceratocnemum is a genus of flowering plants belonging to the family Brassicaceae. It includes four species endemic to Morocco. Ceratocnemum aphanoneurum Ceratocnemum ballii Ceratocnemum × mirabile Ceratocnemum rapistroides Coss. & Balansa
