The purpose of this application, under Article 81.1 of the Code, is to conserve the name Antheraea roylei Moore, 1859 believed to be the progenitor of Bombyx (Saturnia) pernyi Guérin-Méneville, 1855 (currently Antheraea pernyi). Tussah silk is second only to mulberry silk (from Bombyx mori) in world production and consumption. Recently compiled evidence indicates that the tussah silkmoth, also called the Chinese oak silkmoth, Antheraea pernyi Guérin-Méneville, 1855, was derived thousands of years ago in China from the Himalayan Antheraea roylei Moore, 1859, which would place the latter in synonymy under the former, since the two names refer to the same biological species. Although there are no significant and consistent differences in wing pattern and genitalia, both names have had wide usage for more than 150 years, and the two entities differ in their chromosome numbers and cocoon structure. The name A. roylei has been applied by almost all authors to wild collected material in India, Burma, Nepal, Thailand, etc., while the name A. pernyi has been used by Chinese and Korean authors for sericultural populations and wild collected specimens in southern China, although the wild collected material does not differ from that of countries that share borders with southern China. The authors propose that the name Antheraea roylei be conserved and added to the Official List of Specific Names in Zoology.
