Abstract: A new subspecies of the White Desert Land Snail from the

genus Sphincterochila (Class Gastropoda, Superfamily Helicoidea, Family Sphincterochilidae, Subfamily Sphincterochilinae) was found in the Umm Dimna (Dimona) Area in Al-Naqab (Negev) Desert, Occupied Palestine. The new subspecies is distinguished from the subspecies Sphincterochila boissieri boissieri which lives in Al-Naqab and Sinai by its slightly different shell structure. It is morphologically a distinct subspecies. The new subspecies was named Sphincterochila boissieri ummdimna Khalaf, 2014.

Introduction:

During a field trip to the Umm Dimna (Dimona) Area and to the North of Umm Dimna (Between Beer Al-Sabea’ [Beersheba] and Umm Dimna) in Al-Naqab (Negev) Desert, Occupied Palestine on Monday the 22nd December 2014, accompanied by the Palestinian Researcher Daoud Al-Hali; I inspected the desert area around Umm Dimna, and saw many white desert snail shells (Sphincterochila boissieri Charpentier, 1847) which was scattered over a vast area in the desert; many of these shells were covered by sand. Specimen snail shells were collected, examined, measured and photographed. Sphincterochila boissieri Charpentier, 1847 is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Sphincterochilidae. This species lives in the Palestinian Al-Naqab Desert and the Sinai Desert (Egypt). Sphincterochila boissieri is the type species of the genus Sphincterochila. The type species was subsequently designated by Dr. Sc. Henry Augustus Pilsbry in 1895.

Description and Distinctive Features:

Shell Description

The shell of Sphincterochila boissieri is covered perforate, thick, irregularly striated, somewhat effulgent, cretaceous and colored white. It has 5 slightly convex whorls. The last whorl is deflected anteriorly. The aperture has a thick lip, projecting internally above in two thick, subconfluent tubercles. The average width of the shell is 25 mm (Wikipedia).

Anatomy and Physiology

The average body mass of Sphincterochila boissieri is around 4.3 g. Such mass is divided evenly between the shell and the animals’ soft parts. Schmidt-Nielsen et al., in 1971, found that 56% of the animal’s body mass was contained in its shell. About 80 to 90% of the mass of the soft body parts is composed of water (according to the Yom-Tov 1970). In average, soft body parts contain 81% of water (nearly 1400 mg of water), 11% of proteins, 4% of ash, and little other organic matter. Sphincterochila boissieri has no energy reserves and the amount of lipids it contains is a fraction of 1%, which is considered to be extremely low (Wikipedia).

Ecology

Habitat

Sphincterochila boissieri lives in desert environments. This snail is common in areas with loess-limestone soils, and uncommon in areas that have a flint substrate.

Yom-Tov measured the maximum demographic density for Sphincterochila boissieri, encountering a value of 0.2-0.3 specimens/m² in the area of the Naqab (Negev) desert he investigated in 1970. The snail Xerocrassa seetzeni was found to be more abundant there. On the other hand, in the Northern Naqab (Negev) area investigated by Steinberger et al. in 1981 Sphincterochila boissieri was the most abundant snail.

Sphincterochila boissieri along with other snail species and algae are the most significant faunal and floral components of the Naqab (Negev) and Sinai deserts ecosystems (Wikipedia).

Adaptations for arid conditions

This species presents adaptations to arid conditions which significantly improve its desiccation tolerance. Some of those adaptations include a thick shell with a relatively reduced aperture (Machin 1967), a thick epiphragm, and slow body surface heat conduction. About 90% of its shell surface reflects the visible portion of the solar spectrum, and much over 90% of the solar spectrum itself. Sphincterochila boissieri also produces a new epiphragm after every period of activity (Yom-Tov 1971).

These snails dig themselves into the soil to depths from 1 to 5 cm while they aestivate during summer in the Negev Desert. In the vicinity of the Dead Sea, they usually either burrow to depths of up to 10 cm, or aestivate hidden under stones.

All dormant snails of this species can resist ambient temperatures up to 50 °C, but temperatures of 55 °C and above are usually lethal. The soft parts of the animal's body shelter inside the second and the third whorl of its shell, where the temperature can reach up to 50.3 °C. Temperatures of up to 56.2 °C were measured and are known to occur inside the shell's body whorl, which is mostly filled with air during aestivation (Wikipedia).

Dormant snails experience water loss of 0.5 mg per day per snail in summer, with a very low oxygen consumption rate. For these reasons, dormant Sphincterochila boissieri can survive severe droughts for several years (Wikipedia).

Life Cycle

Sphincterochila boissieri is active for a few days only after rainfall during the winter season, from November to March. At this time of the year they feed, mate, and lay eggs. Thus these snails are active for only 5-7% of the year (nearly 18 to 26 days), and aestivate during all the rest of the time (Wikipedia).

Dormant snails are known to have survived in museum collections for up to 6 years. Schmidt-Nielsen et al. in 1971 estimated their life span according to their oxygen consumption as being nearly 8 years (Wikipedia).

Feeding Habits

Sphincterochila boissieri feeds on soil, especially loess mud after rains, lichens, soil algae and surface of limestone directly. It does not eat higher plants (Wikipedia).

Predators

The known predators of Sphincterochila boissieri are rodents, namely the Cairo Spiny Mouse (Acomys cahirinus), Wagner's Gerbil (Dipodillus dasyurus) and the Asian Garden Dormouse (Eliomys melanurus) (Wikipedia).

Distribution

Sphincterochila boissieri lives in Al-Naqab (Negev) Desert in Palestine/Israel, and the Sinai Desert in the Sinai Peninsula (Egypt). The new Umm Dimna subspecies Sphincterochila boissieri ummdimna Khalaf, 2014 lives in the Umm Dimna (Dimona) Area in the Northern Al-Naqab (Negev) Desert, Occupied Palestine.
