Pilumnopeus convexus (Maccagno, 1936)

Persian Gulf. Saudi Arabia ( Apel 2001), Bahrain ( Apel 2001), UAE ( Cooper 1997; Apel 2001), Iran (present study).

Iran. Hormozgan Province: Qeshm I. (26 stations around the island), Bandar-Kolahi, Bandar-Abbas, Baghestan , Bostanu , Bandar-Pohl , Bandar-Khamir , Mahtabi , Bandar-Lengeh , Bandar-Hassineh , Chiruyeh , Moghdan . Bushehr Province: Khalij-Nayband, Bandar-Dayyer, Mond Protected Area, Chapahn, Bandargah , Bushehr (Jofreh), Chahak . Khuzestan Province: Bandar-Emam .

General distribution. Western Indian Ocean: South Africa, Red Sea, Gulf of Aden, Persian Gulf, Gulf of Oman.

Habitat. Rocky/cobble intertidal, oyster bank, muddy substrate with shells.

Remarks. Pilumnopeus convexus is one of the most common species found in a variety of habitats along the intertidal coast of the Persian Gulf. Apel (2001) stated that the records of P. vauquelini (Audouin, 1826) from the Persian Gulf by Stephensen (1946), Basson et al. (1977) and Hornby (1997) are more likely based upon misidentifications of P. convexus . Further taxonomic work is needed for being able to distinguish the different species of the genus, in particular these two closely related species.
