Two new Italian species of the genus Islamia (Prosobranchia: Hydrobiidae), one living in eastern Sicily (I. cianensis), and one on Elba Island (Tuscan Archipelago, Italy) (I. gaiteri) are described. The two species are distinguished on the basis of shell and anatomical characters, mainly those of the male genitalia. I. cianesis n. sp. is characterized by a valvatoid shell and a penial lobe with internal band of glandular tissue not distinct in its lower portion from the penis body but bulging apically as a small knob. I. gaiteri n. sp. is characterized by a planispiral shell and a small lateral penial lobe without internal glandular tissue. © 1995 The Malacological Society of London.

Abstract

Two new Italian species of the genus Islamia (Prosobranchia: Hydrobiidae), one living in eastern Sicily (I. cianensis), and one on Elba Island (Tuscan Archipelago, Italy) (I. gaiteri) are described. The two species are distinguished on the basis of shell and anatomical characters, mainly those of the male genitalia. I. cianesis n. sp. is characterized by a valvatoid shell and a penial lobe with internal band of glandular tissue not distinct in its lower portion from the penis body but bulging apically as a small knob. I. gaiteri n. sp. is characterized by a planispiral shell and a small lateral penial lobe without internal glandular tissue. © 1995 The Malacological Society of London.
