Review of the Genus Malayaxenos Kifune (Strepsiptera: Corioxenidae) with the Description of Four New Species

Abstract. Although the generic name implies that the genus Malayaxenos Kifune is from Southeast Asia, the current distribution is more cosmopolitan. Species are now known from Germany, United States of America, Dominica, Colombia, Australia, and Malaysia. As part of this distribution, four new species are named: Malayaxenos baileyi new species, Malayaxenos dominicensis new species, Malayaxenos kogani new species, and Malayaxenos platycephala new species. Additionally, Australoxenos Kathirithamby is proposed here as a junior synonym of Malayaxenos, making its only species Malayaxenos yetmaniensis new combination. All species in Malayaxenos are herein described or reviewed and a world key is provided for species identification.
