Hooge MD & Smith JPS 2004 (citation). Mature specimens ~510 µm long and ~100 µm wide (Figs. 9A, 10A). Body cylindrical. Anterior and posterior ends rounded; posterior more blunt. Body color gold by transmitted light. Epidermis completely ciliated. Many large rhabdoid glands present; mostly concentrated at anterior end (Fig. 9A). Frontal organ well developed; cell bodies of frontal glands positioned ~80 µm behind frontal pore (Fig. 9A). Mouth opening on ventral surface, middle of body. Ovary unpaired, ventral; extends ~150 µm posteriorly from level of mouth (Fig. 9A). Testes paired, lateral to ovary, compact; separate from ovary. Testes extend from level of mouth posteriorly to seminal vesicle. Female gonopore, seminal bursa, and female accessories all absent. Male gonopore terminal at posterior end of body; gonopore closer to ventral side. Proximal opening of long (~60 µm) ciliated antrum surrounded by ring of large mucoid glands whose tips open into antrum (Figs. 9, 10B). Antrum body-wall musculature composed of circular and longitudinal muscles; antrum musculature surrounded by darkly staining nuclei-perhaps insunk nuclei of antrum epithelium. Large unwalled seminal vesicle positioned at proximal end of male antrum (Figs. 9B, 10B).[From Hooge MD, Smith JPS (2004)]
