Remarks. Otostigmus diringshofeni was the last species of centipede to be described by Wolfgang Bücherl and the most recently described species of Parotostigmus. In the original description of O. diringshofeni, the type locality was cited as São Paulo, but the label of the holotype states São Paulo de Olivença, northwestern Brazil, near the border of Colombia (Figure 42). This Otostigmus species resembles O. pococki by the rugose dorsal integument, the presence of median longitudinal keel and longitudinal keels on each side of the paramedian sutures on the tergites and a digitiform appendix which emerges from the base in dorsomedian position in the prefemur of the ultimate pair of legs. The shape and length of the digitiform appendix and position of the tuft of hairs are similar to O. rex also, but O. diringshofeni differs from the latter in the absence of paramedian keels on tergites and the presence of two tarsal spurs on first three pairs of legs. Bücherl (1969) stated that O. diringshofeni was related to O. insignis, O. silvestrii, O. lavanus and O. mesethus by the similarity of the digitiform appendix in male of O. diringshofeni, but it was distinct from those by the absence of a distal prolongation of the coxa of legs 19 and 20.
