Fig. 3. Light micrographs of an Acromyrmex rugosus spermatheca: (A) General appearance of the spermatheca with regions of columnar (Ce) and flat (Fe) epithelia in the reservoir and spermathecal gland (Gl) containing cells with a well-developed nucleus (black arrow). Scale bar: 30 μm. (B) The reservoir epithelium and transition between columnar (Ce) and flat epithelia (Fe). Scale bar: 10 μm. (C) The spermathecal gland (Gl) containing cells with a well-developed nucleus (black arrow) and cytoplasm with granules. Scale bar: 10 μm. (D) The spermathecal pump with muscles (Mu) associated with the spermathecal duct (D). Scale bar: 10 μm. Lu, lumen; Mu, muscles.
