FIGURE 43 in Monographic revision of the endemic Helix mazzullii De Cristofori & Jan, 1832 complex from Sicily and re-introduction of the genus Erctella Monterosato, 1894 (Pulmonata, Stylommatophora, Helicidae)
FIGURE 43. Autographic note by Monterosato (Civic Museum of Natural History, Milan) commenting on several mazzullii specimens caught on Monte Pellegrino in 1912: "… Appartiene al genere Erctella, Monts.. da me pubblicato e adottato da Pilsbry. Pei suoi caratteri anatomici differisce notevolmente dal Cryptomphalus (aspersa)" (for English translation see Discussion section).

Maximum Likelihood consensus tree inferred from the 16S rDNA sequence alignment representing a in Monographic revision of the endemic Helix mazzullii De Cristofori & Jan, 1832 complex from Sicily and re-introduction of the genus Erctella Monterosato, 1894 (Pulmonata, Stylommatophora, Helicidae)
FIGURE 42. Maximum Likelihood consensus tree inferred from the 16S rDNA sequence alignment representing a possible reconstruction of Helicidae phylogeny. Initial trees for the heuristic search were obtained automatically. A GTR + Γ model (alpha= 0.29) was employed. The analysis involved 58 nucleotide sequences. All positions containing gaps and missing data were eliminated.
