Albia (Albiella) yorkensis n. sp.

( Figs. 5–7 View FIGURES 4 – 7 )

Material examined. Female holotype, Gordon Creek, Iron Range NP, Queensland, Australia, 7-ix-2000 (QM).

Diagnosis. Suture line of Cx-2/3 incomplete, ending at U-shaped suture line of Cx-3/4. U-shaped suture line of Cx-3/4 ending near median fusion point of Cx-1/2; palp relatively slender.

Description. Female: Idiosoma 1029 long and 693 wide. Anterior idiosoma margin rounded. Glandularia D3 and D4 close to each other. Glandularia L1 and L2 distanced from each other. Suture line of Cx-2/3 not ending near median suture line, but at U-shaped suture line of Cx-3/4. Cxgl4 extending far forward, in the U-shaped suture line of Cx-3/4; the latter suture lines ending at median suture line near fusion of suture lines of Cx-1/2. Setae of coxae not enlarged. Posterior of median suture line a somewhat triangular sclerite. Width of genital field 332. Genital plates with many acetabula. Lenghts of PI-PV: 50, 106, 83, 132, 44. Lengths of I-leg-4-6: 96, 110, 90. Lengths of IV-leg-4-6: 96, 110, 90; IV-leg-5 with eight swimming setae, IV-leg-6 ventrally with seven stout setae. Male: Unknown.

Etymology. Named after Cape York Peninsula, where the type locality is situated.

Remarks. The new species is close to Albia lundbladi Cook, 1986 from Australia and A. oenakensis Wiles, 1992 from Papua New Guinea. It differs from A. lundbladi in the suture line of Cx-3/4, which does not end at median suture line, while in A. lundbladi this suture line ends at the median suture line. The U-shaped suture line of Cx-3/4 extends more anteriorly compared to A. lundbladi , while in the latter species the U-shaped suture line is fused with the median suture line posteriorly of the fusion point of Cx-1/2 and close to the fusion point of Cx-1/ 2 in A. yorkensis . In the female of A. oenakensis the U-shaped suture line of Cx-3/4 extends also far anteriorly, but the suture line of Cx-2/3 is complete, extending at the median suture line. Furthermore, PIV of A. yorkenis is more slender compared to A. oenakensis and D3 and D4 are in one line with D 5 in A. oenakensis , while in A. yorkensis D5 are lying more posteriorly.
