the
lateral oviduct
which unite to form the common (

oviduct
. The
gonopore
(opening)
of the common oviduct is usually concealed in an inflection of the body wall that typically forms a
cavity, the
genital chamber
. This chamber serves as a capulatory pouch during mating and thus
is often known as the
bursa copulatrix
. Its external opening is the
vulva
. In many insects the
vulva is narrow and the genital chamber becomes an enclosed pouch or tube referred to as the
Vagina
.
Two types of ectodermal glands open into the genital chamber. The first is the

epermatheca is single and sac-like with a slender duct, and often has a diverticulum that forms a
