In both phorozooids and gonozooids, M6 ventrally continuous, although narrowing substantially. Endostyle extending from M21/4 to M43/4. Neural ganglion at M31/3. Gill-septum extending dorsally to M3 and ventrally behind M5, its posterior bend surpassing M6. Ovary at M6. Testis opening near the ovary, running forward to about M51/2 on the left side, then looping back behind and above the intestine, ending towards the right side, where it usually becomes slightly enlarged. Gonozooids up to 8 mm long.
