环纹硬结线虫的配子体发生在硬体硬结线虫若虫的肠道内。第5天后补给(p.r.)肠道细胞内有球状和卵形寄生虫。这些阶段被认为代表受精的大配子。它们经历了一个转化过程，最终导致运动阶段的分化，在第14-17天离开肠道细胞。并穿透了唾液腺的小泡。静止细胞转变为活动细胞的过程是由一个生长的突起形成一个内部增大的液泡而发生的。在这个过程中，液泡的界膜作为发育运动期的外膜，而膜的2个内膜是新形成的。环状毛霉的这一分化步骤与红孢子菌的动粒形成过程进行了比较。
Gamogony of T. annulata occurs within the intestine of nymphs of the tick Hyalomma anatolicum excavatum Koch. After the 5th day post repletionem (p.r.) of the ticks, spherical and ovoid parasites were found within the intestinal cells. These stages were thought to represent fertilized macrogametes. These underwent a transformation process leading ultimately to the differentiation of a motile stage, the kinete, which left the intestinal cells on the 14th-17th day p.r. and penetrated the alveoles of the salivary glands. The transformation of the stationary into a motile stage took place by formation of a growing protrusion (= anlage) into an inner, enlarging vacuole. During this process the limiting membrane of the vacuole served as the outer membrane of the developing motile stage, whereas the 2 inner membranes of its pellicle were newly formed. The steps of this differentiation in T. annulata were compared to the process of ookinete formation in Haemosporina.
