Figure 7 in To be or not to be a tibial comb: A discussion on the (past) use of tibial armature in tribal/subtribal organization in Cholevinae (Coleoptera: Leiodidae)

Figure 7. Apex of protibiae. (A-B) Ptomaphaminus chapmani (Peck), right leg (mirrored image), (A) ventral and (B) dorsal views; (C) Proptomaphaginus puertoricensis Peck, ventral view (used with permission and modified from fig. 19 in Perreau, 2000); (D-E) Eucatops sp., (D) dorsal (note the serrate nature of the external margin of the protibia in this species) and (E) ventral views; (F-H) Eucatops (Napocatops) giganteus Salgado, (F) lateral-external, (G) ventro-lateral-external, and (H) lateral-internal views. gp = 'gap' on the apical crown of spines around base of spur; is = inner spur; os = outer spur; the arrow shows the point where the spines stop circling the apical margin of the protibia and start to follow the external margin of the protibia, instead of making a complete apical crown; the rectangle highlights the presence of a series of small spines that extends from the internal portion of the apical crown of spines (to the left of the figure) towards the external comb of spines (to the right of the figure); the circle highlights the series of spines at the inner face of the protibia; the ellipse highlights the longitudinal row of strong spines along the outer margin of the protibia.
