Fig. 2 in Reinstatement of the New Zealand cave wētā genus Miotopus Hutton (Orthoptera: Rhaphidophoridae) and description of a new species

Fig. 2. Apical spines on the left hind tibia of Pleioplectron simplex Hutton, 1896 (MPN CW3459), numbered as in Fig. 1 (from Fitness et al. 2015). Dorsal view of posterior distal section of left hind tibia including part of first tarsal segment. Four pairs of 'apical' spines are commonly present: the inferior subapical pair S19 & S20 (not visible here); inferior apical pair S17 & S18 (S17 obscured here); superior apical pair S15 & S16; superior subapical pair S21 & S22. Some taxonomists have treated S21 & S22 as the first pair of superior linear spines, resulting in recording of three pairs of 'apical' rather than four.
