Box 9517, NL-2300 RA, Leiden, <[email protected]> 2 LIMOS, CNRS, UMR 7137, Université Henri Poincaré Nancy I, Faculté des Sciences, B.P. 70239, F-54506, Vandoeuvre-lès-Nancy Cedex, <[email protected]> Abstract Twenty-four species of Odonata were found in the Egyptian Nile Valley and Western Desert in May 2009, which represents 71 % of the fauna confirmed for African Egypt. Agriocnemis sania Nielsen, 1959 was recorded in the lower valley and delta of the Nile. This suggests that a doubtful old record of a damaged Agriocnemis exilis Selys, 1872 from Port Said referred to A. sania, and that A. exilis should be removed from the checklist of Egyptian, North African and Mediterranean Odonata. Agriocnemis sania is new to African Egypt and should be downgraded from «Regionally Extinct» to «Endangered»on the IUCN North African Red List. Orthetrum machadoi Longfield, 1955 was discovered in the Siwa Oasis and is new for Egypt and the Palaearctic at large. The site is over 2600 km from the nearest known locality in Ethiopia, and, like the sympatric and sometimes syntopic Acisoma pan orpoides Rambur, 1842, can be considered as a tropical relict from (a) pluvial period(s), more than 6,000 years ago, when the Sahara was considerably wetter. The over- all proportion of observed Afrotropical species was 71 %, whereas the Palaearctic element was only 25 %. Zusammenfassung Erste Aktualisierung des «Atlas of the Odonata of the Mediterranean and North Africa»: Orthetrum machadoi neu für die Paläarktis und Agriocnemis sania neu für das ägypti- sche Niltal – Im Mai 2009 wurden im nördlichen Niltal und in der Westlichen Wüste 24 Libellenarten nachgewiesen, was 71 % der aus dem afrikanischen Teil Ägyptens eindeu- tig nachgewiesenen Arten entspricht. Agriocnemis sania Nielsen, 1959 wurde im Unteren Niltal und im Nildelta nachgewiesen. Damit sollte ein alter Nachweis eines beschädigten Exemplars von Port Said, das bisher als Agriocnemis exilis Selys, 1872 angesehen wurde, A. sania zugeordnet werden und A. exilis von den Check-Listen Ägyptens, Nordafrikas und Libellula 29 (1/2) 2010: 107-125 ©Ges. deutschspr.

Agriocnemis sania ist neu für die Fauna des afrikanischen Teils von Ägypten und sollte entsprechend in der Roten Liste der nordafrika- nischen Libellen des IUCN unter «gefährdet» statt unter «regional ausgestorben» geführt werden. Orthetrum machadoi Longfield, 1955 wurde in der Oase Siwa entdeckt und ist damit sowohl neu für Ägypten als auch für die gesamte Paläarktis. Diese Stelle liegt mehr als 2600 km vom nächsten bekannten Fundort in Äthiopien entfernt. Zusammen mit der sympatrisch und manchmal syntop vorkommenden Libelle Acisoma panorpoides Rambur, 1842 kann O. machadoi als tropisches Relikt einer bzw. mehrerer niederschlagsreicher Pe- rioden vor mehr als 6.000 Jahren angesehen werden, als die Sahara bedeutend feuchter war. Bei der Untersuchung betrug der Anteil der afrotropischen Arten 71 %, während die paläarktischen Elemente nur 25 % ausmachten. Introduction Egypt has been rather poorly investigated for Odonata and in this respect is hard- ly known better than nearby Libya. Major papers are those by (1928), (1950), (1974, 1978a, 1980), (1990) and (1994). This situation is surprising considering the touristicAndres attractiveness Kimmins Dumont Dumont & Fossati Geene of the country that results from its archaeological heritage. Following an IUCN workshop in Cairo dedicated to the evaluation of red lists of African Odonata in- May 2009, we undertook a field trip south of Cairo with Jens Kipping and Frank Suhling, subsequently proceeding to the Nile Delta and, with Kevin Smith and Sar inah aFerriss, depression to Siwa that Oasis is largely in the below Western sea Desert. level and The was latter visited lies 50with km the east purpose of the ofLibyan updating border data and obtained 255 km bysouth of the (1950).Mediterranean As a result coast of (29°12’N these efforts, 21°31’E) the knowledge presented in the recent «Atlas of the Odonata of the Mediterranean et Kimminsal. 2009) must be updated for some species.
