FIGURES 22–26 in Temnocephala pignalberiae Dioni, 1967 (Platyhelminthes, Temnocephalida) from two allopatric populations of Dilocarcinus pagei Stimpson, 1861 (Crustacea, Decapoda) — first record for Brazil

FIGURES 22–26. Temnocephala pignalberiae, photomicrographs of seminal vesicle, prostatic bulb, and cirrus, dissected from specimens from Poconé, mounted in Faure´s mounting medium, observed with Nomarski´s DIC microscopy. 22. seminal vesicle, prostatic bulb, and cirrus. Scale bar = 50 µm. 23. prostatic bulb and cirrus. Scale bar = 50 µm. 24. cirrus, showing the proximal end of the shaft curving in (black arrow). Scale bar = 10 µm. 25–26. cirrus introvert observed in two different focusing planes, indicating the proximal limit of the spineless introvert (white head arrow) and the retractor muscles (black arrows). Scale bar = 10 µm.
