Remarks. Thus far, the male was unknown and a description is given below. The male matches the description of the female well, but P4 has a ridge which was not mentioned by Smit (2017) for the female.

Description. Male: Idiosoma dorsally 431 long and 272 wide, ventrally 431 long. Dorsum as typical for the genus. Anterodorsal margin of ventral shield with a few serrations. Length/width of anterodorsal plate 141/181, length/width of posterodorsal plate 156/124,

length of anterolateral dorsal plate 169. Projections associated with insertions of fourth leg truncate. A ridge present posterior to the insertions of the fourth leg. Posterior margin of venter with a large indentation, gonopore not visible in ventral view. Length of P1­5: 22, 41, 27, 53, 20. P2 with a short anteroventral extensions without papillae (one pennate seta located dorsally on P2), P4 with a ridge over almost its entire length. Length of I­leg­4­6: 50, 58, 57. Length of

IV­leg: 55, 93, 41, 51, 50, 64. Fourth leg typical for the genus, with IV­leg­2 being the longest segment.
