  • Stenohya curvata Zhao, Yong-Wei, 2011, Zootaxa 2834: 58-61.

Materials Examined

Type material.Holotype male (Ar.-MHBU-YN 100303), China: Yunnan Province, Dali City, Cangshan Mountain [25 ° 44 'N, 100 °05'E], alt. 2700 m, 3 March 2010, Zi-zhong Yang leg. Paratypes: three females, same data as for holotype.

Etymology

Etymology. The name curvata is from the Latin meaning “curved or bent” and refers to the form of the movable chelal finger.

Diagnosis

Diagnosis. This new species resembles S. hamata (Leclerc & Mahnert, 1988) in having a spine on the chelal hand, but it can be distinguished from the latter by: the movable chelal finger curving in basal third (Fig. 7), whereas it is straight in S. hamata; the spine being situated laterally on the hand in S. curvata (Figs. 4, 7, 8), as opposed to ventrally in S. hamata; and a tubercle present near the spine (Fig. 7), which is absent in S. hamata.
