Abstrack: Forty-two species of Cossidae representing 27 genera are reported for Socialist Republic of Vietnam. Three species (Paracossus zyaung Yakovlev sp. nov., Phragmacossia laklong Yakovlev sp. nov., Butaya auko Yakovlev sp. nov.) are described as new to science. Five species (Paracossus indradit Yakovlev, 2009, P. griseatus Yakovlev, 2009, Aholcocerus ihleorum Yakovlev & Witt, 2009, Skeletophyllon puer Yakovlev, 2011, Azygophleps scalaris (Fabricius, 1775) are new country records. A brief biogegraphical overview of the Cossidae of Vietnam is given.
Introduction: The Cossidae of the Socialist Republic of Vietnam have been studied extensively in recent years. Yakovlev & Witt (2009) have provided a synopsis of the fauna, and Yakovlev (2006, 2011) recorded additional species and new species. A total of 34 species had been reported so far. Recently collected material by the staff of the Ulyanovsk Pedagogical University, Russia during expeditions in 2009–2013 has been become available for study. This material included new records of genera and species for
Vietnam in addition to three new species, which are described below. An updated annotated checklist of the
Cossidae of Vietnam is provided.
Biogegraphical overview: The cossid fauna of Vietnam includes 27 genera and 42 species placed in three subfamilies. Thirteen species are considered to be endemic, Catopta tropicalis, Paracossus zyaung, Hollowiella chanwu, Roepkiella loeffleri, Chinocossus vjet, Streltzoviella owadai, Phragmacossia fansipangi, P. laklong, Roerichiora bachma, Butaya auko, Lakshmia sirena, Bergaris ruficeps, and B. solovievi. The Vietnamese Cossidae includes five assemblages: (1) endemic Indochine species (16 species); (2) species distributed from India or Central China to Indochina (nine species); (3) species distributed from Indochina through Malacca to the Greater Sunda Islands; (4) Panoriental species (8 species); and (5) widely distributed panpalaeotropical species (1 species).It is significant to note that the two species of the Vietnamese fauna that have Palearctic affinities, namely C. tropicalis and Streltzoviella owadai, are restricted to northern Vietnam. The genus Catopta is widely distributed in major mountain ranges of Palearctic Asia, from Central Yakutia of eastern Siberia. The genus Streltzoviella includes two species which are known from southern areas of the Russian Far East through Central and eastern China to northern Vietnam. The other 40 cossid species known from Vietnam are members of 25 genera distributed throughout the Old World Tropics.
