I that enter the male atrium ventrally. The double-walled prostate stylet is 17–23 µm high (= 21; n = 6). Distally the funnel widens and forms a relatively large collar, which, at one side, projects widely beyond the stylet proper. This collar is 14–17 µm broad (= 15; n = 5, the distal part of the stylet in one specimen is oriented in a way that prevents correct measurements) and has no slit. Its distal rim is only partly provided with delicate teeth.
