The Blastophagini of Taiwan (Hymenoptera: Agaonidae: Agaoninae)

Abstract

This revision of Taiwanese Blastophagini (Hymenoptera: Agaonidae: Agaoninae) covers 8 genera: Blastophaga Gravenhorst, Ceratosolen Mayr, Dolichoris Hill, Eupristina Saunders, Kradibia Saunders, Liporrhopalum Waterston, Platyscapa Motschoulsky, Wiebesia Boucek. A total 23 species belonging to these genera were reared from Taiwanese, endemic figs, whereas 1 species was reared from exotic figs. Eleven species of Blastophagini are recorded from Taiwan for the first time and 7 species are new to science. Key to the species of Taiwanese Blastophaga (Blastophaga) is presented. 榕小蜂亞科（Agaoninae）隸膜翅目、小蜂總科、榕小蜂科（Agaonidae），該亞科之種類爲榕屬植物之授粉蜂。榕小蜂與榕屬植物二者間之關係是典型共生的例子；經長期共同進化的結果，二者在形態與生態特徵上顯示出相互適應的現象；因此，彼此間有很高的專一性。榕小蜂亞科又可分爲榕小蜂族（Agaonini）與食胚容小蜂族（Blastophagini）。臺灣之榕屬植物有44種，其中26種爲自生種，但僅6種有其授粉蜂之記錄。本研究共自23種臺灣自生與1種外來引進之榕屬植物飼育得24種授粉蜂，這些種類均屬於食胚榕小蜂族；其中新種與臺灣新記錄種分別各有7與11種。文中並附臺灣食胚榕小蜂之形質圖。
