Abstract

The anatomy and functions of the male and female reproductive organs of Allothrombium lerouxi Moss are described in detail. In the male, the reproductive organs consist of paired testes, paired vasa diferentia, a median seminal vesicle, a median ejaculatory duct, bursa expulsatoria, a penis, and a median accessory gland; in the female, they consist of paired ovaries, paired oviducts, a median uterus and a vagina. The function of the parts in the male differs from that reported in other species of Trombidiformes, and in females fertilization takes place in the spongy epithelium of the uterus instead of in the oviducts as in oribatids. Females also lack a receptaculum seminis and accessory glands.
