无花果授粉是一个众所周知的专性互利共生的例子，涉及专门的无花果小蜂（Hyattera，Agaonidae）和无花果（桑科）。然而，授粉是知之甚少的Castilleae，最近确定的姐妹组榕。在这里，我们报告的第一个记录蓟马授粉的古热带Castilleae的成员。我们采用物候测量，昆虫诱捕和传粉者排除实验，调查在Antiaropsis decipiens，一个单型雌雄异株树的低地雨林在新几内亚的授粉模式。我们记录了一个新种，在这里描述为蓟马antiaropsidis（Thysanoptera，蓟马科），吃Antiaropsis花粉，在雄花花序中繁殖，并为心皮花序授粉。看来，蓟马是通过欺骗从雄花花序引诱到心皮花序的。我们结合联合收割机这些观察与证据，从新热带区Castilleae的建议，蓟马授粉可能是常见的姐妹组无花果。我们推测，在榕和Castilleae的共同祖先的虫媒早于无花果授粉互惠的起源。
Fig pollination is a well‐known example of obligate mutualism involving specialized fig wasps (Hymenoptera, Agaonidae) and Ficus (Moraceae). However, pollination is poorly understood in Castilleae, the recently identified sister group to Ficus. Here we report the first record of thrips pollination in a member of the paleotropical Castilleae. We used phenological measurements, insect trapping, and pollinator exclusion experiments to investigate the mode of pollination in Antiaropsis decipiens, a monotypic dioecious tree of lowland rainforests in New Guinea. We recorded a new species, described here as Thrips antiaropsidis (Thysanoptera, Thripidae), feeding on Antiaropsis pollen, breeding in the staminate inflorescences, and pollinating the carpellate inflorescences. It appears that thrips are lured from staminate to carpellate inflorescences by deceit. We combine these observations with evidence from the Neotropical Castilleae to suggest that thrips pollination may be common in the sister group to figs. We speculate that entomophily in the common ancestor of Ficus and Castilleae predated the origin of the fig pollination mutualism.
