Coloradoa nodulosa Zhang et Zhong, 1980: 56–57 ( holotype : apterous viviparous female, China : Bejing , in the collection of Institute of Zoology , Academia Sinica , Bejing ), syn. n . NOTES. It is impossible to distinguish Coloradoa nodulosa from C. viridis according to the morphological characteristics available in the descriptions, because the measurement data are included in the amplitude of variability of these characters ( Table 2 ). Both taxa live on the same plant ( Artemisia annua ). Thus, C. nodulosa is considered here as a junior synonym of C. viridis . Table 2.
