spermatheca

(spûr′mə-thē′kə)
n. pl. spermathe·cae (-sē)
A receptacle in the reproductive tract of many female or hermaphrodite invertebrates and certain female vertebrates, in which spermatozoa are received and stored until needed to fertilize the ova.

sper′ma·the′cal adj.

spermatheca

a sac for the storage of sperm, a ‘seminal receptacle’ as occurs in the female reproductive tract of many lower animals, such as insects and PLATYHELMINTHS.

spermatheca

accessory organ opening into the common oviduct in female insects; stores spermatozoa delivered by the male during copulation; the sperm may remain viable for the life of the female.

Epigynal teeth long, slender, arising from slightly anterior to atrium, with contiguous bases and widely separated apices; atrium large, wider than long, situated anteriorly, separated from epigastric furrow by more than its length, with distinct, continuous, arch-shaped anterior margin; copulatory ducts broad, originating anteriorly; spermathecae broad, slightly extended anteriorly, widely separated by about their width; spermathecal heads arising distally on spermathecae (Figs.

Structurally, the spermathecae, associated ducts, and the ventral receptacle are innervated with muscle fibers surrounding the spermathecal capsule, indicating that females may regulate sperm location and use (Fritz 2002; Fritz & Turner 2002).
