urn:lsid:zoobank.org:act:B3F9DB50-0DAA-41C6-9407-A7E9EAC9D4CC

Figs 67–68

Diagnosis

The species is similar to Plexippoides biprocessiger ( Lessert, 1927) from Congo, but differs by the dentition of the tip of the tibia and the retrolateral basal edge of the cymbium. 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.
