Albia crocker n. sp.

( Figs. 38A–D )

Type series. Holotype male, small stream Waterfall Trial, Inobong, Crocker Range, Borneo, Malaysia, 5º 51.306 N 116º 0 8.292 E, alt. 482 m asl, 19-ix-2012 ( RMNH). Paratype: female, same data as holotype ( RMNH).

Diagnosis. Cxgl-4 shifted anteriorly, beyond level of suture lines of Cx-I and Cx-II; (indistinct) suture lines of Cx-II and Cx-III reaching midline, but laterally obsolete; Cx-II and Cx-III with relatively strong setae.

Description. Colour yellowish. Dgl3, dgl-4 and lgl-3 almost on same level in posterior quarter. Suture lines Cx-I/ -II, Cx-II/-III and Cx-III/-IV fused with midline. Cxgl-4 shifted anteriorly beyond suture line fusion point of Cx-I and Cx-II. Lgl-1 shifted medially, located near posterior beginning of anterolateral ridge. Cx-II and Cx-III with thickened setae. Posterior to fourth legs sockets two pairs of small setae and a pair of much longer setae. IVleg-5 with 7 swimming setae, III-leg-4 and -5 with 5 and 3 swimming setae, respectively.

Male: Idiosoma 818 long and 570 wide. Dorsal shield 818 long and 530 wide. Suture lines of coxae laterally indistinct, not extending to lateral coxae margins. Genital plates with 40–42 acetabula. Outer margin of gonopore 53 long. Length of P1-P5: 38, 82, 54, 104, 34. Length of I-leg-4–6: 72, 78, 64. Length of IV-leg-4–6: 110, 122, 88. IV-leg-5 with 7 swimming setae, III-leg-4 and -5 with 5 and 3 swimming setae, respectively.

Female: Idiosoma 974 long and 680 wide; dorsal shield 974 long and 664 wide. Gonopore 74 long, genital field 320 wide. Length of P1–P5: 50, 110, 72, 124, 42. Length of I-leg-4–6: 84, 86, 76. Length of IV-leg-4–6: 130, 150, 112.

Etymology. The species is named after the Crocker Range and is a noun in apposition.

Remarks. The following Albiella species have anteriorly shifted Cxgl–4: A. suvarna Cook, 1967 , A. nesiotes Lundblad, 1971 , A. lundbladi Cook, 1986 , A. juliae Wiles, 1992 , A. oenakensis Wiles, 1992 , A. wauensis Wiles, 1992 , A. wewakensis Wiles, 1992 , A. alexae Wiles, 1992 and to a much lesser extent A. australica Cook, 1986 and A. vanimoensis Wiles, 1992 . Two of these species, A. alexae and A. juliae , have Cxgl–4 shifted much further anteriorly than the new species, and two species ( A. australica and A. vanimoensis ) have Cxgl-4 shifted much less anteriorly. From the remaining species listed above, the new species differs in the presence of thickened setae on the second and third coxae and the presence of an elongated seta posterior to the fourth leg sockets. Moreover, A. lundbladi and A. nesiotes have the suture lines Cx-II/-III and Cx-III/-IV reaching the lateral coxal margin.

Distribution. Borneo; known only from the locus typicus.
