扇形触角在几个昆虫群体的雄性身上进化了无数次，它们携带着嗅觉感受器神经元，使个体能够远距离定位雌性昆虫。在最近的膜翅目中，扇形触角是动物中辐射最大的物种之一，相对较少。这里我们描述了Atefia rasnitsyni gen.ET sp.11月来自巴西的下白垩世Crato组，代表了第一个具有双扇形触角的膜翅目化石。这块化石表明，膜翅目的长距离寻找配偶的行为在下白垩世已经得到了很好的证实。这一新化石在分类学上具有挑战性，并具有与最近的Pergidae和Diprionidae相同的形态特征。然而，它缺乏任何一个家族的明确诊断特征，在这里没有被定位为叶蜂总科的早期谱系。从系统发育的角度讨论了扇形触角在新叶蝉目中的出现和结构多样性。Http://zoobank.org/urn:lsid:zoobank.org:pub:D69866FA-831C-4B72-8E18-1CFA5B87D3DA
Flabellate antennae have evolved numerous times in males of several insect groups where they carry olfactory receptor neurons enabling the individuals to locate females over long distances. In Recent Hymenoptera, one of the largest species radiations among the Animalia, flabellate antennae are relatively uncommon. Here we describe Atefia rasnitsyni gen. et sp. nov. from the Lower Cretaceous Crato Formation of Brazil, representing the first fossil hymenopteran with a biflabellate antenna. The fossil indicates that long-distance mate finding behaviour in Hymenoptera was already well established in the Lower Cretaceous. The new fossil is taxonomically challenging and shares morphological characters with Recent Pergidae and Diprionidae. However, it lacks definite diagnostic features of either family and is here left unplaced as an early lineage of Tenthredinoidea. The occurrence and structural diversity of flabellate antennae in Recent Tenthredinoidea is discussed in a phylogenetic framework. http://zoobank.org/urn:lsid:zoobank.org:pub:D69866FA-831C-4B72-8E18-1CFA5B87D3DA
