Fig. 5. Hr39⁰⁴⁴⁴³ spermathecae lack secretory material and parovaria contain extra secretory material. (A-C) 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.
