Also Philip Edward Bragg, who had already made the experience that the spines in adult Aretaon asperrimus are significantly reduced, mentioned this possibility in 2001, holding a synonymization but for too hasty.

[7] Francis Seow-Choen revalidated the species in 2016 because its syntypes match perfectly with the specimens he found from the Gunung Mulu National Park.

[1][3] Aretaeon muscosus occurs in the Malay part of Borneo, more precisely in the northwestern state of Sarawak.

[4] In July 2014 Albert Kang collected specimens in the Gunung Mulu National Park, which Thierry Heitzmann was able to bring to the Philippines.

The resulting parthenogenetic stock can now also be found in the terrariums of European breeders and was initially called Aretaon sp.

After the revalidation of Aretaon muscosus and the publication of the first pictures of adult specimens by Seow-Choen in 2016, it became clear that the breeding stock is identical to this species both in appearance and in terms of where it was found.
