In the largest comparative study of coniopterygid wax gland head morphology to date, we used scanning electron microscopy to illustrate the ultrastructure of gland heads found in 2 subfamilies (Aleuropteryginae and Coniopteryginae), 5 tribes (Aleuropterygini, Coniocompsini, Coniopterygini, Conwentziini, and Fontenelleini), 9 genera (, , , , , , , , and ), and 28 species of Palearctic and Oriental dustywings collected from a variety of sites across China. We propose a new descriptive terminology to concisely characterize the major elements of gland head ultrastructure and then identify similarities and differences among them and provide detailed descriptions of the wax gland heads found in each of the nine genera examined. Based on the range of taxa examined, we propose hypotheses about the functional morphology of some of the ultrastructural elements examined and relate them to wax ring formation in dustywings. An identification key for the examined genera based on gland head morphology is also presented.
在迄今为止最大规模的粉蛉蜡腺头部形态比较研究中，我们利用扫描电子显微镜展示了在2个亚科（粉蛉亚科和粉蛉亚科）、5个族（粉蛉族、粉蛉族、粉蛉族、粉蛉族和粉蛉族）、9个属（、、、、、、、、和）以及从中国各地不同地点采集的28种古北区和东洋区粉蛉中发现的腺头超微结构。我们提出了一种新的描述性术语，以简洁地描述腺头超微结构的主要元素，然后识别它们之间的异同，并对所研究的九个属中每个属的蜡腺头进行详细描述。基于所研究的分类单元范围，我们对所研究的一些超微结构元素的功能形态提出假设，并将它们与粉蛉蜡环的形成联系起来。还给出了基于腺头形态的所研究属的鉴定检索表。
