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.
