Albia (Albiella) ilikensis n. sp.

(Figures 56–58)

Material examined. Holotype female, stream Ilik, near lake Gita, Anggi Lakes, West Papua Province, New Guinea, Indonesia, 1° 21.423 S 133° 58.553 E, alt. 1912 m asl., 17.xi.2011 (RMNH).

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 2 in the new species is unusual. In A. wauensis Wiles, 1992, which is close to the new species in Cxgl–4 shifted anteriorly, L1, but not L2 have shifted medially and the suture lines separating Cx-III from Cx-IV are not obliterated.
