Epidermis completely ciliated. Uncolored rhabdoid glands uniformly scattered across body, very small, appearing white in incident light, not visible in sections (Fig. 4 AB). Body colorless in transmitted light, except some light brown coloration of digestive syncytium in some specimens (Fig. 4 A). Statocyst located 50 μm behind anterior end, at U 12.

One specimen with large needle-like structures, 40–50 μm long, located around middle of body which is the same location as digestive syncytium thus possibly food material (Fig. 4 C). Ovaries paired, ventral; each lateral band with up to 7 oocytes, extending from middle of body to bursal nozzle, U 50 to U 80 (Fig. 4 A). No female gonopore detected. Well-developed seminal bursa, at U 85, with well-defined ~ 18 μm long bursal nozzle directed ventrally to the anterior (Fig. 4 AB, 5 CD). Testes paired, dorsal; separate from ovary. Testes extend anterior from middle of body to copulatory organ, from U 40 to U 80.
