Patella­tibia I length 5.4, II 3.0, III 1.3, IV 2.6. Abdomen 2.4 long, 0.8 wide. Patellar apophysis bifid, with a large and a short pointed branch. Paracymbium concave in ventral view and with a prolateral branched swelling. TTA with a ventral and an apical process, the latter with a curved, pointed projection (Figs. 15–16).
