Name
Chydaeus satoi Ito, 2003 – Wikispecies link – Pensoft Profile
Material examined
A total of 14 specimens (9 males and 5 females, including 4 males and 2 females in CAS, 4 males and 2 females in IOZ; and 1 male and 1 female in ZIN) were examined from the following localities: China. Yunnan Province. Lushui County: 5 males, 2 females, Luzhang, Yaojiaping, riverside, 25.97722°N, 98.71091°E, 2527 m, 20.V.2005, D. Kavanaugh & D.Z. Dong leg. (CAS, IOZ); 1 male, same data, but 19.V.2005 (IOZ); 3 males, 3 females, Luzhang, Yaojiaping, roadside, 25.97526°N, 98.71000°E, 2515 m, 20.V.2005, H.B. Liang leg. (CAS, IOZ, ZIN).
Distribution
Fig. 58. Chydaeus satoi was previously known only from the type locality (Zhonghe Feng) at an elevation of 2620 m in the Diangcang Shan (Mountains), situated north of Dali, western Yunnan Province, China (Ito, 2003). The additional material listed above was also collected in western Yunnan, but in the Gaoligong Shan, about 150 km to the west of the type locality.
Habitat
Specimens were collected in roadside and road cut open areas (Fig. 64) and on open, disturbed stream banks, hidden under stones and other debris during daylight hours.
Remarks
This species belongs to the semenowi group (Kataev and Schmidt 2006[1]). Male members are very similar in their appearance to those of Chydaeus baoshanensis, but easily distinguished from them by the peculiar median lobe with the terminal lamella very long and markedly bent ventrad (Figs 44–46).
In male specimens from the Gaoligong Shan, the terminal lamella is slightly narrower in dorsal aspect than in males from the Diangcang Shan as illustrated by Ito (2003)[2]. The significance of this difference should be tested by examination of additional material. One of us (HBL) examined the type specimens of Chydaeus satoi at Ito’s home (Kawanishi City, Japan) and found no differences between the type and specimens from the Gaoligong Shan.
