Geographic range
This species has a wide distribution in central Asia but on the Arabian Peninsula it has been recorded only in Oman and Socotra (Collingwood 1985; Collingwood and Agosti 1996; Collingwood et al. 2004).
Ecological and biological notes
Lepisiota spinisquama was collected from dry soil under a date palm tree by sifting. A colony was found nesting under a stone in Dixam Plateau. A nest was collected from under a dead palm tree where the soil had a high degree of humidity and was rich in organic material. Another colony was found under a stone where exoskeletons of minor workers of a yellow Camponotus sp. were present. Workers were observed foraging on the trunk of Boswellia carteri Flueck. (Burseraceae) where many worker of Trichomyrmex mayri (Forel) were also found at the trunk base and the soil was dry. Several mealybugs (Hemiptera: Pseudococcidae) were observed under the bark of the tree. The species was also found nesting under a stone with several dead tenebrionid beetles and a species of the family Lygaeidae (Hemiptera). Several workers of L. spinisquama were foraging on ground where soil was sandy and dry. Several individuals were collected from a dry leaf litter by sifting. A nest was located in a relatively moist, compact clay soil under a stone. Previous observations indicate that this species apparently prefers dry habitats.
