|Scientific Name:||Acritodon nephophilus|
|Red List Category & Criteria:||Critically Endangered B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v) ver 3.1|
|Reviewer/s:||Bergamini, A. & Gärdenfors, U.|
This species has an extremely restricted range with an extent of occurrence of only 16 km² and an area of occupancy of less than 8 km². The population is known from only two widely separated and isolated locations hence it is considered to be severely fragmented. There is continuing decline in a number of parameters due to a variety of threats operating across the whole range of the species. It is therefore listed as Critically Endangered. Attempts are required to look for this species again as it was last observed in 1966 and could potentially have gone extinct because of all the threats.
|Range Description:||Known only from two localities (one collection from each locality): First the type locality: Southern Mexico, Oaxaca, Sierra Juarez above Valle Nacional, Route 175, cloud forest near km 96. Here it was reported as an epiphyte in cloud forest, on tree branches and trunk of Clethra. Last observed year: 1964.
The second locality is: southern Mexico, Oaxaca, slopes at the pass above Llano de las Flores, on the road between Ixtlán de Juárez and Tuxtepec. Trunk of Clethra, 2,743 m a.s.l. Last observed year: 1966.

|Population:||Probably there are less than 100 trees (=phorophytes) which have this species as an epiphyte. Species like Acritodon usually grow in very small patches on the mossy lower part of the tree trunk.|
|Habitat and Ecology:||Grows on the tree bark of Clethra sp. in forested ravines in cloud forest belt (2,700 to 3,000 m.asl).|
|Major Threat(s):||The whole area where the two localities are located are still continuously disturbed by timber-cutting, road construction and cattle raising. The species was last seen in 1966.|
|Conservation Actions:||Protection of the forest at the two known localities is needed. Attempts are required to relocate this species and to survey the population to get more up-tio-date information on its status.|
