(from Boudot & al. 2009:78): Pseudagrion sublacteum mortoni is endemic to the Levant and is believed to be relatively common in its small range. Like the nominal subspecies, it is interpreted as a relict of the past pluvial period.
Morton's Rotaugen-Fee, Pseudagrion sublacteum mortoni Ris & Schmidt 1936, ist bisher aus Israel, Jordanien und Syrien bekannt geworden (Quelle: IUCN) – dort finden wir auch Hinweise zur besonderen Schutzwürdigkeit dieser Art: "The Levantine subspecies is distributed along the Jordan river system and a few coastal rivers between 33° N and 31° N, with an extent of occurrence of less than 20,000 km², and severely fragmented. The species is known from about 20 locations (2002). Signs of decline were already apparent in the 1980s (Schneider 1982). The main reasons for decline were habitat destruction by water engineering, causes which have not ceased (Katbeh-Bader et al. 2002, Schneider 2004).The subspecies is important to understand the history of colonizations of the Levant by African freshwater organisms via the wadi-systems of Arabia (in this case not the Nile)."
