The ultrastructure of the spermathecae in the Collembola Symphypleona (Hexapoda)

Journal of Morphology, 2008
AbstractThe fine structure of the paired spermathecae of two Symphypleona Collembola, Sminthurus viridis and Allacma fusca, was studied. The spermathecal epithelium is rich in pigment granules, while secretory organelles are scarce, consisting of a few mitochondria and microtubules, scattered cisterns of endoplasmic reticulum and Golgi systems.
