【 摘 要 】

The morphological structure of the venom apparatus of Allopecosa fabrilis was studied using scanning electron microscopy (SEM). The venom apparatus is situated in the prosoma and is composed ofa pair of chelicerae and venom glands. Each chelicera consists of 2 parts, a stout basal part covered by hair, and a movable fang. A venom pore is situated on the subterminal part of the fang. Just below thefang, there is a cheliceral groove next to the teeth. Each side of the groove is coveredwith cuticular teeth. The venom glands are large and roughly cylindrical. Each gland is surrounded by completely striated muscular fibers. The venom produced in the venom glands by contraction of these muscular fibers is ejected into the fang through a canaland the venom pore.
