Allomalia cf. quadrivirgata (COSTA, 1863)

The high number of synonyms of A. quadrivirgata listed by Alonso-Zarazaga (2011) already points out that this species shows a considerable morphological variability. On the other hand, the various forms described do not show relevant differences concerning the shape of the apex of the penis as was shown by Giordani-Soika (1937) and Alonso-Zarazaga (1989).

In the present case of the specimens from Samos, the habitus is not different from the general variability of the species ( Figs 5A ), but the shape of the apex of the penis is interestingly very different ( Figs 5B–D ). Only a revision of the genus Allomalia Alonso-Zarazaga, 1989 will show the significance of this trait.
