Vgl-4 lying on a separate platelet. Length of P1-P5: 24/ 13, 38/26, 28/22, 60/18, 20/8. Length of I-leg-4-6: 50, 57, 36. Length of IV-leg-4-6: 58, 62, 46.

Etymology. Named for its occurrence in the mountains.

Remarks. The following species have similar long glandularia platelets in the dorsal furrow and three pairs of acetabula: J. elliptica K. Viets, 1935 , (Java), J. antama Cook, 1967 ( India) , J. punya Cook, 1967 ( India) and J. sunyi Wiles, 1991 (mainland Malaysia). Of these, the only with an indentation in the anterior part of the dorsal shield, J. sunyi , has only two elongated platelets in the dorsal furrow.
