摘要: Agglomerata lacrima n. sp. is the first species of genus described from a copepod host ( Acanthocyclops vernalis .) It was studied using light- and electron-microscopy. All stages life-cycle had isolated nuclei. The earliest found were uninucleate merozoites. Sporogony produced 4–12 (mostly 8) pyriform spores by rosette-like budding within fragile sporophorous vesicle. Live measured 4.4 ± 0.2 × 2.6 μm, fixed 3.7 1.6 μm. exospore constructed 4 layers. anisofilar polar filament made 5–6 coils in posterior half spore. polaroplast an anterior part with wide lamellae (chambers), followed second zone narrow lamellae. Tubule-like structures which might constitute third region present immediately to coil. Cytological characteristics generic position are discussed, it compared related or resembling species, all previously reported microsporidian copepods.
