The coccidian from the black beetle, Heteronychus arator (Fabricius), in New Zealand was identified as Adelina tenebrionis Sautet 1930. Its development occurs in the fat body of the host. Merogony produces bundles of 8–19 vermiform merozoites, which range in length from 12.0 to 24.1 Μm. Spherical macrogametocytes and small, vermiform microgametocytes fuse to form a zygote. Sporogony produces an oocyst 29.2–45.0 Μm in diameter, containing 3–13 sporocysts, 12.3–14.0 Μm in diameter. The life cycle takes about 46 days in an alternative host, Planotortrix excessana (Lepidoptera: Tortricidae), at 22‡ C. Electron micrographs of merozoites and gametocytes are presented.
