(608) long. Integument lineated, eyes and integument without pigment. Dorsal shield 575 (526)

long and 421 (373) wide, with five pairs of glandularia and the postocularia. Dorsal furrow with three pairs of glandularia. Gnathosomal bay posteriorly ending in a slit, gnathosoma elongated,

Cxgl­4 lying in the middle, Cxgl­4 not on the coxae but posterior to Cx­III. A ridge present anterior to insertion of fourth legs. Genital field 162 long and 156 wide, with three pairs of acetabula. Length of P1­5: 20, 80, 53, 114, 30. P2 ventrally with a pointed seta, P3 anteroventrally with a long seta, P4 ventrally with a small setal tubercle with a curved seta.

Remarks. The only other species with five pairs of glandularia on the dorsal shield is L.

conroyi Cook, 1983, but this species has four pairs of glandularia in the dorsal furrow, the gnathosoma is attached to a protrusible tube and Cxgl­4 is lying near the suture line of Cx­III/IV.
