Abstract

The finding of a copulating pair of Coniopteryx (Holoconiopteryx) haematica (Mc Lachlan, 1868) offers the possibility to study the position of the elements of the genitalia of both sexes to each other for the first time in Coniopterygidae by using X-ray microcomputed tomography. The genital sclerites of the male resemble largely those of Coniopteryx (Coniopteryx) pygmaea (Enderlein, 1906) treated previously. Therefore, terminology and interpretation of the genital sclerites following the “gonocoxite concept” are adopted. The dominating eye-catching sclerite of the male is sternite 9 (the hypandrium externum of diverse taxa), the dominating sclerite of the female genitalia is the sclerotized spermatheca embedded in the “copulatory cup” of the hypandrium externum of the male. There is no indication that the genital sclerites of the male, the so called intromittent sclerites, are pushed into the female during copulation. They apparently function as a track for the distal part of the long slim ductus ejaculatorius.

基于微ct成像首次描述了飞翼目（昆虫亚目：神经翅目：神经翅目）中一个完整的交配体

这对正在交配的毛翅鸟（Holoconiopteryx） haematica （Mc Lachlan, 1868）的发现，首次提供了利用x射线微计算机断层扫描研究毛翅鸟科两性生殖器元素相互位置的可能性。雄性的生殖器巩膜与先前处理过的Coniopteryx (Coniopteryx) pygmaea （Enderlein, 1906）的大体相似。因此，生殖器硬石的术语和解释采用了“淋卵石概念”。雄虫最引人注目的硬膜是胸骨9（不同分类群的外膜），雌虫生殖器最引人注目的硬膜是嵌在雄虫外膜“交配杯”中的硬化精囊。没有迹象表明雄性的生殖硬核，即所谓的内向硬核，在交配过程中被推入雌性体内。它们显然是细长射精管远端部分的轨迹。

期刊介绍： Zoologischer Anzeiger - A Journal of Comparative Zoology is devoted to comparative zoology with a special emphasis on morphology, systematics, biogeography, and evolutionary biology targeting all metazoans, both modern and extinct. We also consider taxonomic submissions addressing a broader systematic and/or evolutionary context. The overall aim of the journal is to contribute to our understanding of the organismic world from an evolutionary perspective. The journal Zoologischer Anzeiger invites suggestions for special issues. Interested parties may contact one of the editors.
