Plexippoides dentatus sp. nov. has a tibia with three small teeth and a cymbium with two teeth, while in P . biprocessiger the tibia is divided into two branches and the cymbium has a single tooth (compare Fig. 68C with Wesołowska 2012a : fig. 40).

Etymology The specific name is Latin, meaning ‘toothed’, and refers to the shape of the tibial apophysis.
