Table 4 in Sky islands of the Cameroon Volcanic Line support the westernmost clade of five new Typoderus weevils (Coleoptera: Curculionidae: Molytinae)

Table 4. Character matrix with discrete morphological characters for diagnostics of new Cameroonian Typoderus weevils (see also Discussion). - Characters: 1. - Body, colour of darkest specimens (Fig. 3, that is of a beetle at least a few days old, because specimens freshly emerged from the pupa are much paler): greyish: 0; brownish: 1; blackish: 2. 2. - Elytra at middle in cross-section: triangular (Figs 5A-H, 6A-H); elytral disk flat, ridge in interstriae 6-7 forming elytral lateral contour in dorsal view: 0; cylindrical (Figs 7A-H, 8A-H, 9A-H); elytral disk evenly rounded laterally, ridge in interstriae 6-7 positioned inside lateral contour in dorsal view: 1. 3. - Hind tibiae, additional apical projection near inner apical spur (in at least some males): absent (Figs 7B, 8B, 9B): 0; present (Figs 5B, 6B): 1. 4. - Pilosity on elytral declivity (excluding that on elytral protuberances), whether similar to that on the rest of elytra; similar: 0; dissimilar, notably denser and longer (Fig. 9A, except abraded specimens): 1. 5. - Ratio of length to width of sclerotized part of aedeagus, dorsal view: one (aedeagus subquadrate as in Figs 5E, 6E, 9E or notably unsclerotized, as in Fig. 8E): 1; two (aedeagus elongate, Fig. 7E): 2. 6. - Numerous (about 10) “teeth” inside internal sac of aedeagus: absent (Figs 5E-F, 6E-F, 8E-F, 9E-F): 0; present (Figs 7E-F): 1. 7. - Tegminal apodeme: absent (Figs 6F, 8F) or indistinguishably short (Figs 5F, 9F): 0; present, consisting of two rods (Fig. 7F): 1.
