Abstract

The spermathecae of four species of asilid genus Dysmachus (D. fuscipennis, D. picipes, D. praemorsus, and D. transcaucasicus) were studied with both light and scanning electron microcopy (SEM). There are three spermathecae in all the species examined. The spermathecae consists of a receptaculum seminis, a ductus receptaculum, an ejection apparatus, a furca, and an apodeme. Spermathecae of D. picipes, D. praemorsus, and D. transcaucasicus have just swollen at base but they extend apically like a duct; the spermatheca of D. fuscipennis is long and cylindrical. In all species; the receptacular surface and the spermathecal duct are covered by chitin layer. The ejection apparatus is generally located in the middle of spermathecal ducts, cotrolling the passage of spermatozoa. The surroundings of the ejection apparatus are covered by strong muscles that regulate its opening and closing.
