pubmed:abstractText
The haplogyne spider D. erythrina possesses two distinctly different sperm storage organs: a bilobed anterior spermatheca and a large, sac-like posterior diverticulum. The glandular equipment of both storage types is markedly different: the glandular tissue of the spermatheca is composed of complicated glandular units comprising a cuticular ductule and three canal cells (class 3 cells) whereas the glandular tissue of the posterior diverticulum is composed of simple gland cells that discharge their product through the cuticle (class 1 cells). Thus, the glandular products produced differ, leading to different storage conditions for the spermatozoa from copulation to egg laying. It is suggested that multiple organ types have evolved to facilitate specialization in short-term and long-term storage and to allow (posterior diverticulum) or prevent (spermatheca) males from accessing previously stored sperm.
