E. Gray, 1838 , Nile Valley, Egypt . Two subspecies are recognized.	P.c.christiiJ.E.Gray,1838—EgyptandNSudan. P. c. petraeus Benda, 2008 — S Israel , SWJordan, and NE Egypt ( Sinai ).	Head-body 42-54 mm , tail 42-48 mm , ear 32-39 mm , hindfoot 8-9 mm , forearm 36-4—41- 3 mm ; weight 6-8 g . Race petraeus has larger body and skull than nominate. Dorsal fur very pale umber brown or greyish brown (hairs 8:5-9- 3 mm long; tricolored, with basal onehalf rusty brown, terminal one-half pale brownish grey with umber brown or pale brown at tip); ventral pelage whitish (hairs 8:5-9- 3 mm long; dark rusty brown with creamy or white tip). Face pale and almost naked; forehead covered with short white hairs; muzzle long and narrow. Long ears are translucent, unpigmented except for pale brown tips; typically have numerous horizontal furrows, and inner margins joined by low band at base; tragus mostly translucent but brownish around distal margins, moderately long (one-half ear height), and tapering to blunt point. Wings are thin, semi-translucent, pale gray, and apparently unpigmented. Compared to other long-eared bat species, thumb is rather short (5:5- 5-6 mm ). The speciesis morphologically different from other sympatric Plecotus in pale color, small, narrow baculum, and medium-large tympanic bullae (4:3—4- 6 mm ). Skull smaller than in other congeners (condylo-basal length 14:9-15- 6 mm ), with broad braincase. Mandible proportionally short and muzzle blunt. Chromosomal complement has 2n = 32 and FNa = 50.	Occurs in various habitats of subtropical desert and semi-desert belt of Sahara. Reported foraging in mesic habitats close to rivers such as the Nile, in oases close to seashore, in open areas around water, and inland in mountains; also beach resort buildings, monasteries, gardens, other buildings, and natural pools.	Feeds mainly on Lepidoptera (100% moths, in feces from Israel ), although grasshoppers and beetles have also been reported. In Dead Sea area, this species consumed Lepidoptera , but also Trichoptera, Coleoptera , and Diptera .	In the Negev Desert, southern Israel , a female was in early stages of pregnancy in early March. In Dead Sea area, 50% of females captured in mid-April were lactating, with one still lactating in mid-June. Nursery colonies can harbor up to 40 individuals in rock crevices, tunnels, and caves.	Roosts in caves and underground sites. Echolocation only recently described, but is almost identical to that of the Gray Long-eared Bat ( P. austriacus ). Christie’s Long-eared Bat uses broadband, low-intensity FM-QCEFpulses at 20-30 kHz, with second harmonic at 45-60 kHz, which is usually fairly intense. Frequencies of maximum energy are 31-4-35-6 kHz, start frequencies 42-5-48-7 kHz, end frequencies 20-8-25-7 kHz, and durations 1:3-1-7 milliseconds. It is considered a “whispering” species due to general weak intensity of pulses.	Usually forms colonies, but has also been reported roosting solitarily.	Classified as Data Deficient on The IUCN Red List. Locally abundant within its very small range. No population estimates exist, but its natural habitat is reduced and heavily fragmented; probably affected by anthropic disturbance, especially at roosts.	Aloufi et al.

The species is confirmed as Data Deficient.	Roosts in remote buildings outside urban areas and crevices in rocks, caves and mines. Found in mesic habitats along the Nile River and in open arid habitats around oases in the desert (is not found in cultivated habitats).	The species is affected by human disturbance.	Probably very small population, only scattered and isolated records.	Unknown	Known only from a few localities in NE Africa, including eastern Libya (S. Aulagnier pers. comm. 2007), Egypt including Sinai and Sudan. A specimen from Eritrea may belong to this species or to P. balensis (Kruskop and Lavrenchenko 2000).		Terrestrial	None in place.

Not listed.	Data Deficient	 austriacus species group. Gray (1838) described Plecotus christii in honor of John Turnbull Christie. The species epithet was later altered by Thomas (1911) to  christiei . Thomas (1911) made no comment on the change. This spelling ( christiei ), attributed to the original describer (Gray, 1838), remains in use today and was the "prevailing usage" from 1911 until roughly 2004. Spitzenberger et al. (2006) argued that Thomas' (1911) change in spelling was a "corrected subsequent spelling," apparently assuming that the stem for the epithet would be 'christie-' however, as Benda et al. (2014) later pointed out, the latinized name 'Christius' yields 'christi-' as the stem rather than 'christie-'. Benda et al. (2014: 112) go on to suggest that the correct form of the name is christii , the original spelling, rather than christiei , since "The use of original spellings originating from latinised personal names currently absolutely prevails over the emended spellings (comp. e.g. Ellerman & Morrison-Scott 1951 and Simmons 2005)." However, this suggestion ignores sections 33.2.3.1 and 33.3.1 of the ICZN, which state that spellings in prevailing use and attributed to the original describer should be considered "justified emendations" and preserved as the "correct original spelling". Thus the correct form is  christiei , which we preserve here since it has been in prevailing use for more than a century and its preservation is in accordance with the Code. We further suggest that conserving these names following the Code's own guidelines not only helps stabilize taxonomy, but simplifies and improves data management in the digital age.

However, since the Spitzenberger et al. (2006) and Benda et al. (2014) papers, christii has become widely used. We admit the difficulty of maintaining "prevailing usage," except in extremely rare cases (see Dubois, 2010), and as a consequence accept the original spelling of christii.
