Claws similar to those on I-L-6 but with out clawlets and with ventral blade much less developed. Palpus. Palpus with P5 long, P4 with large ventral protrusions (as found in some members of the Nica- limnesiinae), P3 with four dorsal setae, P2 with a short, thick and pointed seta on its ventral surface and PI with dorsal seta present. Cheliceme. Cheliceral claw extremely strong with the tip of the claw bent dorsally beyond the level of the dorsal border of the basal segment. Dorsal border of basal segment without elevation and with its proximal end bent strongly ventrally. Chelicerae with 220—260 pm total length. Taxonomic placement The palpus of Shivatonia ^en. nov. differs from palps of the Anisitsiellinae and Bandakiinae in having a long P5, strong ventral tubercles on P4 and a thick ven- tral seta on P2. A similar palpus shape is found in the subfamily Nicalimnesiinae. In Nicalimnesia andha, P5 is even more elongated and the ventral tubercles on P4 are even more prominent. The palpus, however, differs from that of the Nicalimnesiinae in having- D well-visible claws at the tip of P5, and in having a dor- sal seta on PI. The shape of the chelicerae is striking because of their extremely strong claw, w^hich is bent upwards beyond the level of the dorsal border of the basal part. The secondan,' sclerotization, adpressed to the medial border of the genital flaps carr}äng 3 ace- tabula each, expresses a plesiomorphic character state if compared with the situation in Nicalimnesiinae, where the basal sclerite of the acetabula is completely fused to the movable genital flaps (female), or to the genit
