Step | Features and species | |
---|---|---|
1 (8) | Roundish fully grown gametocytes (Fig. 31e, f) are absent | |
2 (9) | The nuclei of macrogametocytes usually are in subterminal position and do not locate close to the erythrocyte nuclei (Fig. 31a, b, d, i) | |
3 (10) | Fully grown gametocytes, which are closely appressed to the nuclei of erythrocytes but do not touch the envelope of the erythrocytes along their entire margin (Fig. 31h, i), are absent | |
4 (5) | The average number of pigment granules in fully grown gametocytes is greater than 15 (Fig. 31a) | |

5 (4) | The average number of pigment granules in fully grown gametocytes is less than 15 (Fig. 31b) | |
6 (7) | Dumbbell-shaped gametocytes are present among growing advanced macrogametocytes (Fig. 31c), and such forms are common | |

7 (6) | Dumbbell-shape gametocytes (Fig. 31c) are absent | |

8 (1) | Fully grown gametocytes are roundish; they markedly deform infected erythrocytes, markedly displace their nuclei, and can even enucleate the host cells (Fig. 31e, f) | |
 | …………………………………………………………………………………………………………………. | |
9 (2) | The nuclei of macrogametocytes are median or submedian in positions; they usually adhere to the erythrocyte nuclei (Fig. 31g) | |

10 (3) | Fully grown gametocytes are closely appressed to the nuclei of erythrocytes but do not touch the envelope of the erythrocytes along their entire margin (Fig. 31h, i) | |
