螨虫的生殖生物学是多种多样的，并且具有系统发育的重要性。在这里，我们描述了卵形毛足动物（C.L. Koch，1839）的交配阶段，并在已知的寄生形交配序列的背景下进行了讨论。使用IP（互联网协议）摄像机观察螨虫。我们确定了 T. ovalis 交配的六个阶段。在T. ovalis中，我们发现：（1）交配起始、精囊形成以及利用雄性螯肢的转移与其他寄生形目相似； (2) 与大多数寄生螨相似，标本在交配过程中采取腹对腹的位置。然后，它们的身体被重新定位，腹侧以一定角度设置，为精囊的生长提供足够的空间，迄今为止，这种情况仅在一种尾足类动物中发现； (3)精囊形成时间比其他尾足类群要短得多，但与目前研究的一些其他寄生螨类似； (4)与迄今为止研究的其他尾足纲相比，精囊转移时间和精液摄取时间(精子泵送)更短； (5)精液摄取机制与其他尾足类群不同，因为两个交配标本均使用腹侧挤压，而其他尾足类在精子泵送过程中使用外雌器运动或触肢/螯肢。尾足纲在精囊转移过程中使用非特化螯肢已得到证实，这表明这种行为是寄生形目的拟形特征。
Reproductive biology of mites is diverse and of phylogenetic importance. Here, we describe the mating phases of Trichouropoda ovalis (C.L. Koch, 1839) and discuss them in the context of known mating sequences of Parasitiformes. Mites were observed using IP (internet protocol) video camera. We identified six phases of mating in T. ovalis. In T. ovalis we found that: (1) mating initiation, formation of spermatophore, and transfer using male’s chelicerae, were similar to that described for other Parasitiformes; (2) similar to most of the parasitiform mites, specimens assumed venter-to-venter position during mating. Then their bodies were repositioned and ventral sides were set up at an angle to provide sufficient space for growing of the spermatophore, as found only in one uropodine species so far; (3) time of spermatophore formation was considerably shorter than in other uropodine taxa, but similar to some of other parasitiform mites studied up to now; (4) time of spermatophore transfer and semen uptake time (sperm pumping) were shorter, compared to other Uropodina studied till now; and (5) semen uptake mechanism differed from other uropodine taxa because of use of ventral side pressing of both mating specimens, while other Uropodina use epigynial movements or palps/chelicerae during sperm pumping. The use of unspecialized chelicerae during spermatophore transfer in Uropodina was confirmed, which suggests that this behaviour is a plesiomorphic character of Parasitiformes.
