Diversity of flower-visiting beetles associated with primitive plants and its evolution of host utilization and exploration of useful pollinators

本文首次对苏铁、棕榈、木兰等原始植物的访花甲虫进行了广泛的调查，阐明了其有用的传粉媒介。Curculionid （Molytinae）和belid （Oxycoryninae）象鼻虫分别是旧热带和新世界热带苏铁的有用传粉者。Acalyptine和Derelomine curculionid象鼻虫分别是热带亚洲和世界其他地区的棕榈树。在北半球包括热带亚洲和南半球，Ochyromerine象鼻虫和ellesine curculionid象鼻虫分别为木兰属植物。它们中的大多数是未被描述的物种或代表新属的事实表明，尽管有椰子和糖棕榈等有用的植物，它们是如何长期未被探索和未被认识的。

Flower-visiting beetles of primitive plants such as cycads, palms and magnollids were surveyed extensively for the first time, and their useful pollinators were elucidated as follows. Curculionid (Molytinae) and belid (Oxycoryninae) weevils are useful pollinators for cycads in the Old and New World tropics, respectively. Acalyptine and Derelomine curculionid weevils are for palms in the tropical Asia and other parts of the world, respectively. Ochyromerine and Ellescine curculionid weevils are for magnollids in Northern Hemisphere including tropical Asia and Southern Hemisphere, respectively. The fact that most of them were undescribed species or representing new genera indicates how they have been unexplored and unrecognized their existence for long in spite of the useful plants such as coconut and sugar palms.
