First records of Truncatellina species from Arabia (Gastropoda: Vertiginidae)

There were no records of Truncatellina species from the Arabian Peninsula so far. We report two Truncatellina species from the ’Asir Mountains in southwestern Saudia Arabia. Truncatellina asirensis n. sp. is characterised by a very small, finely striate shell of 4.5—5 whorls, a callous palatalis that is visible in frontal view and low, deeply situated parietal and columellar denticles. The second Truncatellina species is a very small, edentate, ribbed form that resembles T. brandti Zilch 1960 from the Cyrenaica and T. linearis (Lowe 1852)from Madeira in size and sculpture.
