Podomeres lengths (1>7): 0.89; 1.33; 2.84; 1.18; 1.59; 1.99; 0.45. Gonopod aperture, length 1.55, width 3.03. Telson, length 1.68. Gonopod: length 3.17, width 1.88. Gonocoxae: length 0.90, width 1.03. Telopodite: length 3.04, width 0.90. Prefemoral region 1/3 the size of telopodite. Prefemoral process (Fig. 7D) length, broad and without indentations, presenting a dorso-basal lobe, starting from an angle of 135°, ascending parallel to the solenomere and partially covering it in mesal view, in the middle part of the process presents a short trianguliform secondary process, acute apex (Fig. 7D). Solenomere long and narrow (Fig. 7F). Cingulum positioned centroposteriorly (Fig. 7F). Apex of the solenomere acute and abruptly descending (Fig. 7F).
