Featured "In the news" on the Main page of the English (originally without image, later with) as well as - with image - Thai (WebCite) Wikipedia on January 12, 2012, less than 24 h after the taxonomic description had been published by Eric Rittmeter et al. in PLoS ONE. By that time, the respective entries in the Dutch, Finnish, Portuguese, Russian, French, Bulgarian, Hungarian, Thai, Spanish and German Wikipedias, at Wikispecies and Wikimedia Commons had all been started, too - with images imported from the paper. Since then, the Paedophryne amauensis articles in the respective languages have also been featured on the Main pages of the French, German, Chinese, Finnish and Norwegian Wikipedias.
