Structure of spermatophore. a Content of bursa copulatrix immediately after copulation (light microscopy). b Details of collum and corpus of spermatophore (the same sample from a, SEM). c Longitudinal section of spermatophore fixed immediately after copulation with spermatozoa in the sperm sack (brown material removed). d Partially digested spermatophore (sectioned tangentially) in the bursa of a female captured from nature. Spermatozoa have been transported to the spermatheca and the sperm sack looks empty. e Detail of c. f Detail of d showing spermatozoa in the spermatheca. g Couple fixed at 80 min, cross-section of the transversal part of the ductus bursae at the moment of transfer of the collum. h Couple fixed at the 20 min, parasagittal section in the area of signum; the brown material and corpus are not shaped yet. i Couple fixed at 60 min, parasagittal section in the area near the signum; the brown material has been displaced peripherally, the sperm sack is a compact fibrillar mass. 1 corpus, 2 collum, 3 white material, 4 aperture (obturated with white material), 5 brown material, 6 sperm sack, 7 sperm bundles. Scales: a–d, g–i 200 μm; e, f 50 μm
