Without body pigmentation or eyespots. Glassy in appearance. Statocyst 10–12 µm in diameter located ~50 µm from anterior end. Frontal organ present and large. Two large vacuoles present at the posterior end; smaller vacuoles present laterally and in the anterior, though more numerous in the posterior body. Epidermis 4 µm thick, uniformly covered with cilia. Cilia ~4 µm long. Rhabdoids absent. Mouth located at the secondquarter of the body, 15 µm long in fixed specimens. Ovaries paired. Female pore clearly separate from male pore, ciliated, opening ventral, ~9 µm long. Female atrium present, ~11 µm deep in fixed specimens leading to a short vagina and bursa. Bursa present 75 µm from posterior end, 28 µm long and 34 µm wide, with a single ventrofrontally directed cellular appendix. Sperm was not observed in the bursa of any specimen examined. Testes paired, located laterally approximately onequarter of the way from the anterior end of the body. Vas deferens large and clearly evident toward male copulatory organ, with evident sperm. Male copulatory organ present ~45 µm from posterior end, spheroid, ~35 µm long and ~30 µm wide in living specimens. Penis present as a simple inpocketing of the epidermis, 17 µm in fixed specimens, with a shallow male atrium. Male pore large, 15 µm long, ciliated.
