( Figs. 23 A –CView FIGURES 23 A – C)

Type series. Holotype male, Kemantis stream, Sayap, Mt Kinabalu, Borneo, Malaysia, 6 º 0 9.841 N 116 º 33.936 E, alt. 928 m asl, 16 -ix- 2012 ( RMNH).

Diagnosis. Glandularia platelets in dorsal furrow relatively short, dgl- 1 close to lateral margin of dorsal shield far distanced from postocularia, gonopore relatively wide.

Description. Male: Colour yellowish, idiosoma 486 long and 348 wide. Dorsal shield 462 long and 300 wide, with three pairs of glandularia and posteriorly a pair of setae without glandularia; slightly indented anteriorly; embracing Lgl- 1 positioned in dorsal furrow. Eyes and structures on anterior part of dorsal shield hardly visible. Dgl- 1 lying close to lateral margin of dorsal shield, and relatively far away from postocularia. Dorsal furrow with four pairs of glandularia platelets, the second and third ones boat-shaped, and three pairs of slit organs. Gonopore enlarged, 42 long and 36 wide. Cxgl- 4 fused with ventral shield. Length/height of P 1 -P 5: 22 /13, 38/24, 38/19, 54/ 18, 24/ 8; P 3 long, P 5 slender. Length of I-leg- 4-6: 56, 50, 56. Length of IV-leg- 4-6: 60, 64, 50. Legs without swimming setae.

Female: Unknown.

Etymology. Named for the sole occurrence of the new species.

Remarks. Javalbia montana  n. sp. differs from the new species in having cxgl- 4 on a small platelet separated from the ventral shield. Moreover, the glandularia platelets in the dorsal furrow of J. montana  are much longer, while the gonopore is less wide. Also Javalbia elliptica K. Viets, 1935  from Java has elongated glandularia platelets in the dorsal furrow; furthermore, dgl- 1 are away from the lateral margin, lying much closer to the postocularia than in the new species. In the holotype, the genital field is aberrant, with one left acetabulum reduced.

Distribution. Borneo; known only from the locus typicus.
