Eight Newly Recorded Species of the Subfamily Allantinae (Hymenoptera: Symphyta: Tenthredinidae) from South Korea
The subfamily Allantinae is one of the large subfamilies within the family Tenthredinidae with about 900 described species in the world. All of the species are worldwide distributed and 322 of them are from Eastern Palaearctic region. Also, in the neighboring countries, it has been recorded that 275 species in China, 90 species in Japan and 131 species in Russia. But only 15 species have been reported in South Korea. Generally subfamily Allantinae can be easily recognized from other subfamilies by the following characters in fore wing: Veins M and Rs+M meeting Sc+R at or very near the same point; vein 2A+3A complete, always separated from 1A by an anal crossvein; veins M and 1m-cu parallel; vein 2r present. Moreover, all larvae of Allantinae are phytophagous and external feeders on the foliage of the host. In this study, we report eight species belonging to the five genera (Allantus, Ametastegia, Apethymus, Asiemphytus and Taxonus) from South Korea for the first time. As a total of 11 genera and 24 species in Allantinae were identified to occur in South Korea. A key, diagnoses and photographs of the diagnostic characters are provided.
