Anteriorly with two pairs of lateral ciliary furrows, bordering a pair of almost horizontal wings. With frontal glands and glands connected with the ciliary furrows. Pharynx plicatus. Ovarial follicles without concentration to a distinct part of the female gondads. Follicular testicles ventrolaterally. Common genital pore (almost) terminally. Common oviduct feebly glandular, opening from the dorsal side into the atrium. Thin-walled globular prostatic vesicle. Ejaculatory duct tubiform, in resting condition forming a short cylindrical proximal penis, with penial glands discharging in a broad distal girdle. Mostly with nematocysts derived from the food and in adult condition with egg-capsules or embryoes in the gut.
