MEIDIAMA MARCUS, 1946 Diagnosis (emended after Martens & Curini-Galletti, 1993): 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. Type species: Meidiama lutheri Marcus, 1946. There are three species that are very similar, except for the hard parts of the copulatory organ and the number of testes. They are described together, mainly based on material of Meidiama uruguayensis sp. nov.
