Delosia ornata is a species of cockroach in the family Ectobiidae. It is endemic to Desroches Island in Seychelles.
In its latest assessment for The IUCN Red List of Threatened Species in 2007, the species was categorized as Critically Endangered. [1]
Described in 1924, the species was known only from the holotype male until a female and two nymphs were discovered in 2006. [2]
The species is endemic to Desroches Island in Seychelles. A 1997 article published in Oriental Insects notes that the species has also been reported from Sri Lanka. [3] It inhabits coastal woodland fragments, thriving in deep leaf litter dominated by Hernandia nymphaefolia and Guettada speciosa . [1]
Threats to its habitat include historical deforestation for coconut plantations in 1906, leaving only small woodland fragments (<100 m2) for its survival. An extensive fire in 2007 damaged woodland habitat, and the potential impact of this on the coastal woodland remnant remains uncertain. While some areas have regenerated to 1000 m2, in 2012, it was reported to be facing a severe threat from a planned hotel development jeopardizing its entire range. The island, all less than 1 m above sea level, faces further threats from rising sea levels. [1]
In 2006, it was estimated that there were fewer than 300 adult individuals and 600 juveniles of the species. [1]
The species was classified as Critically Endangered in its most recent assessment for The IUCN Red List of Threatened Species in 2007. [1]
The Seychelles palm frog is a species of frog that is endemic to Silhouette Island in the Seychelles. It is closely related to Gardiner's frog, Sechellophryne gardineri.
The Seychelles skink also known as the Mangouya, is a species of skink in the family Scincidae. It is endemic to the Seychelles.
The blue-winged racket-tail or Sulu racquet-tail is a species of parrot in the family Psittaculidae. It is endemic to Tawi-Tawi island in the Philippines and is one of the most endangered parrots in the world. It is threatened by habitat loss and the poaching for the cage-bird trade.
The Fijian mastiff bat, also known as the Fijian free-tailed bat, is a species of bat in the family Molossidae. It is found in Fiji and Vanuatu. In 2013, Bat Conservation International listed this species as one of the 35 species of its worldwide priority list of conservation. This species is currently listed as endangered and considered a species of special concern due to habitat fragmentation and cave disturbance. The Fijian free-tailed bat is endemic to Fiji and Vanuatu. This species was previously documented on the islands of Taveuni and Vanua Levu, current research indicates possible small fragmented populations inhabiting both islands. Only two insectivorous bats occupy Fiji, the Pacific sheath-tailed bat and the Fijian free-tailed bat. Both species consume night flying insects, foraging high above the canopy.
The Aldabra flying fox is a species of megabat in the genus Pteropus. It is endemic to the Aldabra Atoll in the Seychelles, like Chaerephon pusilla, though the latter may be the same species as the little free-tailed bat.
The Seychelles sheath-tailed bat is a sac-winged bat found in the central granitic islands of the Seychelles. They are nocturnal insectivores that roost communally in caves. The species was previously abundant across much of the archipelago, but has since seen a substantial loss of habitat. The International Union for Conservation of Nature has listed the species as being critically endangered, due to population decline. This is mainly due to an increase in land development and the introduction of invasive species.
The tiger chameleon, also known as the Seychelles tiger chameleon, is the only species in the resurrected genus Archaius. Initially placed into Chamaeleo, it was for some time moved to the genus Calumma by some. It is an endangered species of chameleon, found only on the Seychelles islands of Mahé, Silhouette and Praslin.
Anapistula seychellensis is a species of araneomorph spider that is endemic to the islands of Silhouette, Praslin and Curieuse in the Seychelles. It can be found in woodland habitats in leaf litter. It is threatened by habitat degradation caused by invasive plant species, especially Cinnamomum verum.
Andasta benoiti is a species of ray spider that is endemic to the Seychelles. It is found on the islands of Mahé, Conception, Thérèse, North, Praslin, Marianne, Felicite and Denis. It is found in coastal woodlands. It is threatened by coastal development and habitat degradation from invasive plants, especially Cinnamomum verum.
Argyrodella is a monotypic genus of Seychelloise comb-footed spiders containing the single species, Argyrodella pusillus. It was first described by Michael I. Saaristo in 2006, and is found on the Seychelles.
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.
The Mangareva kingfisher, also known as Tuamotu kingfisher, is a species of kingfisher in the family Alcedinidae, endemic to Niau in French Polynesia. It is classified as critically endangered.
The Seychelles giant millipede is a species of millipede endemic to Seychelles.
Seycellesa is a genus of spiders in the family Theridiidae. It consists of only its type species: Seycellesa braueri, which is endangered and endemic to the Seychelles.
The Mahé boulder cricket is an insect species endemic to Mahé island in Seychelles. This species of cricket is only found in two localities, the Morne Seychellois National Park and "La Reserve". The species had not been recorded since 1909, until its rediscovery in 2014. It is a restricted range species, with an area of occupancy less than 10 square kilometres (3.9 sq mi) and with a very fragmented population.
Afrolychas braueri, commonly known as the Seychelles forest scorpion, is a species of scorpion in the family Buthidae. It is currently thought to survive only on Silhouette Island, Seychelles, although the species was historically found on two additional Seychellois islands. This scorpion lives in leaf litter in forests that are largely unaffected by invasive plant species. It is a small yellowish-brown scorpion with three prominent keels on the dorsal surface of its mesosoma, which distinguishes it from other scorpions. While not much is known about the Seychelles forest scorpion's ecology due to the paucity of sightings, it is known to rely solely on its venom to capture its prey and defend its young. Its venom is not dangerous to humans.
Carausius scotti, or Scott's stick insect, is an insect species endemic to Silhouette Island in the Seychelles. It was assessed as critically endangered in The IUCN Red List of Threatened Species in 2007 as a restricted range species with an area of occupancy of 10 square kilometres (3.9 sq mi) with an estimated extent of occurrence (EOO) of 18 square kilometres (6.9 sq mi). The species is primarily threatened with declining woodland habitats due to invasive plants and also climactic factors such as droughts. It is present in the protected area of Silhouette National Park as a part of conservation efforts, however more conservation actions are needed, as well as further research to determine population sizes and trends.
Ideoblothrus seychellesensis is a species of pseudoscorpion. It is found in the Seychelles on Felicite Island and Silhouette Island. As of 2012, the species has been considered endangered and is listed on the IUCN red list.
