毛列

右区纤毛列前延至体缘并跨至背面。横纹条带整圈连续，其前部横跨背面而后部则嵌于细胞边缘。

Cross-striated band continuous , with anterior portion lying across dorsal surface and posterior portion running along cell margin .

形态学研究表明，两个品系的雌成虫在体色、触角结构、前翅毛列等26个重要形态学特征上没有明显差异。

Morphological study inferred , two strains are identical in twenty-four important morphological characteristics on body color , antenna structure , setae on fore wing , etc.

外毛细胞静纤毛副毛与列外内毛细胞。

Extra stereocilia on outer hair cell and extra inner hair cell .

横棘毛5-8根，背触毛6-7列，无尾棘毛；

- 8 transverse cirri and 6-7 dorsal kineties .

charon表面有额腹、横、尾部棘毛10、5、4根，背触毛12列，大核倒C形，小核球形。

Charon is characterized by 10 fronto-ventral , 5 transverse , 4 caudal-marginal cirri and 12 rows of dorsal bristles . The macronucleus and micronucleus are respectively " C " - shaped and spherical .

外毛细胞静纤毛束转位，静纤毛副毛与列外内毛细胞是遗传变异引起的。

The rotation of stereociliary bundles and extra stereocilia on the outer hair cell as well as the extra inner hair cell are induced by genetic variation .
