Figure 12 in The phylogeny and diversification of the western Eurasian Phaedusinae (Gastropoda: Stylommatophora: Clausiliidae)

Figure 12. Correlation of the morphological traits and habitat preferences with the phylogenetic positions. Dark squares denote species with: A, semi-apostrophic aperture; B, presence of basal crest; C, non-marginally ending subcolumellar lamella; D, dorsal lunella; E, high-ending inferior lamella; F, palatally serrate peristome; G, interrupted subcolumellar lamella; H, non-marginally ending inferior lamella; I, decollated shell; J, proximal insertion of the penis retractor muscle at the epiphallus; K, bipartite penis with rhomboidal papillae; L, short and muscular distal penis; M, presence of penial caecum; N, presence of penial verge; and O, subterranean habitat. Solid bars identify the two major groups of the western Phaedusinae.
