Hr3904443 spermathecae (SP). (A) Sperm remain in
lumen (L) but cell death (asterisk) is increased; gland cell, red outline.
Scale bar: 10 µm. (B) Lumen with sperm (S) surrounded by
extracellular material (M). Scale bar: 2 µm. (C) Secretion appears
absent from end apparatus (EA). Scale bar: 1 µm. (D)
Hr3904443 parovaria. Secretion (arrows) appears to fill
the end apparati (EA). Scale bar: 10 µm. N, nucleus.
