No accessory glandular organ. The prostate vesicle is anteriorly oriented and the seminal vesicles enter the vesicle at its anterior side.

[From Martens PM, Curini-Galletti MC (1993): 85]

Filiform Meidiamidae with the prostate vesicle curved over about 180°, and with the proximal pole directed forwards, where the paired seminal vesicles enter; the distal pole, where the stylet is attached, is also directed forwards. The stylet is directed forwards and accompanied by the atrial needles. Accessory glandular organ absent. Genito-intestinal duct leading backwards from the female pore to a resorbing bursa in the gut. Female duct with a prepenial vagina, and functioning as a (prepenial) copulatory bursa.
Emended after Martens & Curini-Galletti (1993).
