Gregarina niphandrodes , a new species of septate eugregarine, is described from the adult mealworm, Tenebrio molitor . Measurements given are means in μm. Gamonts in association. Nuclear diameter consistent, 35.5. Primite: protomerite hemispherical; length 59.5; width 91.2; deutomerite ovoid; length 173.4; width 145.6; total length 232.9. Length of protomerite/total length index 25.7. Length of deutomerite/total length index 74.3. Length of protomerite/length of deutomerite index 35.4. Width of protomerite/width of deutomerite index 63.5. Satellite: protomerite hemispherical; length 40.2; width 81.6; deutomerite ovoid; length 177.4; width 113.9; total length 217.6. Length of protomerite/total length index 19.0. Length of deutomerite/total length index 81.0. Length of protomerite/length of deutomerite index 23.8. Width of protomerite/width of deutomerite index 76.7. Gametocysts spherical, diameter 225, producing multiple oocyst chains under dry storage in 36–52 h. Oocysts very uniform in shape and size, dorsum doliform with angles squared by enclosing sheath, length 8.8, width 5.5; flattened dorsoventrad with mesad tumidus, pleuron height 2.2. Morphological measurements, indices, and oocyst descriptions are given for G. cuneata, G. polymorpha and G. steini .
