Scymnus (Neopullus) camptodromus Yu and Liu

( Fig. 2)

Scymnus (Neopullus) camptodromus Yu and Liu 1997 , in Yu et al. 1997 (Yunnan, Sichuan).

Distribution. China (Yunnan, Sichuan).

Specimens Examined. Types (22 total), Yunnan: Lijiang: Heyuan (5), Ninglang (5); Sichuan: Baoxing (2). Others (84 total), Yunnan: Lijiang : Heyuan (40), Yunshanping (6); Sichuan: Baoxing : Nibagou (38) .

Remarks. The illustrations for this species are reproduced here. Yu et al. (1997) stated that the head is brown in the male and dark brown or black in the female. Having examined specimens in addition to the two male types, the head color does not seem sufficient to distinguish the gender, but the shape of the abdominal apex can separate the sexes. This species has been imported into the United States for evaluation as a biological control agent of Adelges tsugae .
