A: pp). The copulatory organ is 70 µm long (measured on one specimen) and is provided with a conical pouch. Several groups of small, basophilic prostate glands end in the cirrus, which is 30 µm long (measured on one specimen). The length of the copulatory organ mentioned by

is much shorter than that measured by us, and at 30 µm, corresponds more to the length of the cirrus of our specimens. Therefore, it is likely that Reisinger in this case used the term &quot;copulatory organ&quot; as a synonym of what is normally referred to as the &quot;cirrus&quot;. The cirrus is mostly straight, although in some specimens it bends in the proximal half. Moreover, in one of our specimens it became strongly bent after fixation (

BE). Its distal half is lined with sclerotized warts, which increase in size towards the most distal end and become somewhat pointy. A bursa is lacking. The oviduct forms a seminal receptacle.

mentions a cirrus that becomes much wider proximally and bears 11.5 µm long hooks. Finally, Luthers (1963) figure 3F shows a copulatory bursa, which is absent in Reisingers (1924a) and our specimens. Based on these findings it seems plausible that the specimens studied by Luther might represent a different species.
