Sitalcicus gardineri is an allegedly extinct species of harvestmen in the family Podoctidae. The species was endemic to Mahe Island of Seychelles. It has not been found since originally described in 1911.
Pleorotus was a monotypic genus of Seychelloise huntsman spiders containing the single species, Pleorotus braueri. It was first described by Eugène Louis Simon in 1898, and was endemic to the Seychelles. The description was based on a single male collected on Mahe Island in 1894, but none have been found in later collections, and it has been declared extinct.

Dicrogonatus gardineri is an extinct species of mite in the order Holothyrida, endemic to the Seychelles island of Mahé, where it was found in 1909. No other sightings have been recorded since, despite efforts to find it again in 2002 and 2011–12. This species became extinct due to the deterioration of habitation following the introduction of the cinnamon tree Cinnamomum verum.
Centrobunus braueri is an allegedly extinct species of arachnids in the order Opiliones, endemic to the Seychelles island of Mahé, where it was found in 1894. No other sightings have been recorded of this species. Therefore, the species has been declared as extinct. Habitat deforestation due to the introduction of the cinnamon tree Cinnamomum verum has been determined to be the cause of extinction.
