Eucarlia is a genus of spirobolidan millipedes containing six species; most of which are endemic to the island nation of Seychelles, and one native to the Indonesian island of Sulawesi. Four of the Seychelles species have been assessed by the IUCN Red List as either endangered, critically endangered, or extinct.
Thomasettia a genus of spiders in the family Sparassidae, with a single species, Thomasettia seychellana, first described in 1911. It has not been found since, and has been declared extinct. It was endemic to Mahe Island and Silhouette Island in the Seychelles.
Stipax is a genus of spiders in the family Sparassidae, with a single species, Stipax triangulifer, first described in 1898. The description was based on a male collected in 1894. No specimens have been found since and the species has been declared extinct. It was endemic to Mahe Island in the Seychelles.

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 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, despite efforts to find it again in suitable habitats. 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.
