Pseudagrion arabicum has been reported from nine records in six localities in southwest Saudi Arabia and west Yemen. Its extent of occurrence has been calculated (minimum convex polygon of the point localities where the species has been recorded) in approximately 12,800 km², and its area of occupancy is 6 km² (sum of 1 km² grids for each of the known localities), or 12 km² (if a 2 km² grid size is used). The species lives in an arid to sub-arid area of low precipitation (≤ 200 mm/yr) in which agriculture develops using surface and underground water for irrigation. The water table of the Sanaa area is presently at a worrying low level due to over exploitation. The number of locations has been estimated as five. Future degradation of the habitats may be expected in this area, with a predicted population growth in Yemen from 18 million to over 30 million inhabitants between 2000 and 2015 (FAO 2006). This increase will increase the demand of water resources and consequently will cause a reduction of suitable habitats, and therefore an overall decline of the species. In the future, global climate change may have additional negative impacts too. The species is therefore listed as EN B2ab(iii).

Geographic Range [top]

Range Description:Pseudagrion arabicum is a rare endemic species of southwestern Arabia with a rather small range in the Red Sea mountain chains of Saudi Arabia and Yemen. The estimated extent of occurrence is 12,800 km², and the area of occupancy (based on a 1 km² grid size) is 6 km² (or 12 km² if a 4 km² grid size is used). According to published information, this is a high mountain species ranging from 2,000 to 3,000 m asl. Nine records are available from six different localities (five locations). Fifty five percent of the records date from 1990-1996 and no further record has been published since 1996.
