Diagnosis.
Suture lines separating Cx-I and -II well developed, suture line Cx-II/III laterally obliterated, proximally ending near IV-leg sockets. Suture lines separating Cx-III and Cx-IV obliterated, but medial, posterior and posterolateral border of Cx-IV well pronounced. Cxgl–4 shifted far anteriorly; L2 located far anteromedially, posterior to Cx-III; suture lines of Cx-III and Cx-IV obliterated.

Description.
Female: Colour yellowish, idiosoma 773 long and 551 wide. Dorsal and ventral shields present. Anterior coxal plates not extending to anterior idiosoma margin. Suture lines separating Cx-I and -II well developed, suture line Cx-II/III laterally obliterated, proximally ending near IV-leg sockets. Suture lines separating Cx-III and Cx-IV obliterated, but medial, posterior and posterolateral border of Cx-IV well pronounced. Cxgl-4 shifted far anteriorly. L1 near anterior lateral ridge, L2 shifted far medially, located near posterolateral edge of Cx- III. Genital field with numerous acetabula (approximately 34). Lengths of PI-PV: 40, 64, 50, 74, 37; PV with one long and pointed terminal claw. Lengths of I-leg-4–6: 60, 58, 46. Lengths of IV-leg-4–6: 96, 98, 72. Third and fourth legs with swimming setae, but due to mounting no reliable setae numbers can be ascertained.
Male: Unknown.
Etymology.
Named after the stream where the species has been found.
Remarks.
The medial shifting of L

the new species is unusual. In
