Male A2 with t-setae transformed into sensory setae, z-setae transformed into claws. Female A2 with G2-claw as long as G1 or G3. Exopod of A2 consisting of small plate and three setae of which one long. Male prehensile palps asymmetrical and both with hook-like fingers, but right palp with shorter, stockier and considerably less hook-like finger. L6 with basal seta and with one seta on each endopodal segment, except last, which carries two setae and one claw. L7 with only d1- and dp-seta on basal segment, e- and f-setae missing, g-seta long; terminal segment with short h1-seta and h2- and h3-setae equally long; penultimate segment fused without any notable subdivision. UR with both claws and setae present. Zenker organ with 4+2 whorls of spines. The anterior part (cap) more hemispherical and margin not sclerotized, lattice-like structure not well-developed; cap also with long radiating spine-like projections. Hemipenis with relatively large a-lobe not projecting laterally. M-peace terminally foot-like; ejaculatory process (bursa copulatrix) not terminally pointed, and with broad, rounded, finger-like extension; this process also with lateral thorn-like ornamented part.</paragraph>

We also noted some other morphological characters that improve the genus diagnosis, such as a very short finger on the right prehensile palp, a short basal seta (d1) on the walking leg, undivided penultimate segment of the cleaning leg, a foot-like shape of the M-peace of hemipenis, and ejaculatory process finger like and pronounced. Females also seem to have a long G2-claw on the second antenna, and Zenker organ has long spine-like projections on anterior end. Based on the redescription of two
