Type Locality. Kef Azigza Cave (or Tazzouguert Cave), 5.7 km S of Ksar Tazougart, 19 km W-NW of Boudenib, Er Rachidiyah Province, Morocco (32 °01’ 46.6” N, 03° 47’ 16.7” W, 1060 m a. s. l); for a detailed description of the site see Aulagnier and Destre (1985).
Description and Diagnosis. Miniopterus maghrebensis sp. nov. is a medium-sized member of the genus Miniopterus Bonaparte, 1837 in most respects similar to M. schreibersii (Kuhl, 1817) s.str. (Figs. 2, 3, 4, 5). Forearm length 45–48 mm, condylobasal length of skull 14.7–15.3 mm, zygomatic width of skull 8.4–9.1 mm, length of upper tooth-row (canine to third molar, incl.) 5.7–6.2 mm (for all measurements, n = 25).
The dorsal pelage in M. maghrebensis sp. nov. is chestnut brown to dark greyish-brown, the ventral pelage is pale brown (Fig. 2). Ventral hairs are bicoloured, dark brown on the proximal parts, pale brown to buffy in the distal parts. The dorsal skin of ears and the naked parts of face are pale greyish-brown, the ventral skin of ears is almost without pigments, fleshy pale to pinkish (Fig. 2). Wing membranes are dark brown to dark greyish-brown.
Based on the skull size (cf. Fig. 3), M. maghrebensis sp. nov. conforms to the Central European representatives of M. schreibersii s.str., however, is slightly larger than most of the south-European and Levantine specimens, exceeding them on average by ca. 0.3–0.5 mm in largest skull measurements. The rostrum of M. maghrebensis sp. nov. is wide, the width across the infraorbital foramina is large, 4.0– 4.4 mm; the relative width of rostrum (infraorbital width of rostrum / largest length of skull) is very large in comparison to M. schreibersii s.str.: 0.27–0.28 in M. maghrebensis sp. nov. versus 0.24–0.27 in M. schreibersii s.str. from Europe and the Levant. The braincase in M. maghrebensis sp. nov. is high, the height of braincase (incl. the tympanic bullae) 7.7–8.4 mm; the relative height of braincase (largest height of braincase / largest length of skull) is large in comparison to M. schreibersii s.str.: 0.51–0.53 in M. maghrebensis sp. nov. versus 0.45–0.52 in M. schreibersii s.str. from Europe and the Levant. Mandibular molar-row is relatively short in M. maghrebensis sp. nov., its relative length (lower molar-row / mandible length) is 0.326 –0.331 (while 0.336 –0.359 in M. schreibersii s.str. from Europe and the Levant). M. maghrebensis sp. nov. has very distinct tubercle on the dorsal surface of the ramus mandibulae between the third molar and the coronoid process and on the zygomatic arches (cf. Fig. 3 & Šrámek et al., 2013).
*IBP: Interval Between Pulses.
Compared to M. schreibersii s.str. from Europe and the Levant (see Šrámek et al., 2013) unicuspidal teeth are more robust in M. maghrebensis sp. nov. The cingulum on the palatal side of the first upper molar has a very distinctive concave fold between the protoconus and the hypoconus in M. maghrebensis sp. nov.
Measurements of the Holotype (in mm). External: Forearm length 45.8; head and body length 60; tail length 63; ear length 13.4; tragus length 6.3. Cranial: greatest length 15.15; condylobasal length 15.12; zygomatic width 8.59; width of interorbital constriction 3.58; neurocranium width 8.17; neurocranium height 6.31; largest horizontal diameter of tympanic bulla 2.97; rostrum width across upper canines 4.53; rostral width across third upper molars 6.27; length of upper tooth-row (canine to third molar, incl.) 5.93; condylar length of mandible 10.74; coronoid height of mandible 2.57; length of lower tooth-row (canine to third molar, incl.) 6.26.
Genetic Characters. Mitochondrial DNA. The GenBank sequence (partial Cytochrome b, tRNA-Threonine, tRNA-Proline, HV1) of the holotype corresponds to the accession numbers KJ535784 & KJ535824. M. maghrebensis sp. nov. and M. schreibersii s.str. are sister groups, each species forming a strongly supported monophyletic clade (Fig. 6). The average K2P distance between M. schreibersii s.str. and Miniopterus maghrebensis sp. nov. sequences was 1.2%. Nuclear DNA. The microsatellite data are congruent with the mitochondrial DNA signal and provide clear evidence of two strongly isolated and differentiated gene pools which are represented by Miniopterus schreibersii s.str. and M. maghrebensis sp. nov. (Figs. 7 & 8). The Fst between the Miniopterus maghrebensis sp. nov. and M. schreibersii s.str. colonies ranged between 0.44 and 0.49 (significant values).
Etymology. The name maghrebensis refers to the region (the Maghreb; the region of northern Africa located between the Atlantic Ocean, the Mediterranean Sea, and the Sahara) where the new species was discovered. The proposed vernacular names are Maghrebian bent-wing bat (English), Minioptère du Maghreb (French), Murciélago de cueva magrebí (Spanish), létavec maghrebský (Czech), ặ-----ǘdb*Jl Įặ----×ṣ÷لأ d³ ẕ÷ƆƖ-------è*Jl lỪƖ-------ậķJ (Arabic ⵜ ⵙ ⴰ ⵢ ⵍ ⴰ ⵍ ⴰ ⵎ ⴰ ⴼ ⵔ ⵉ ⵡ ⴻ ⴱ ⵢ ⴻ ⵜ ⵉ ⵏ ⵏ ⵜ ⴼ ⵔ ⵉ ⵇ ⵜ ⵓ ⴳ ⴰ ⴼ ⴰ (Berber).
Distribution. Genetic analyses confirmed its presence from northern Morocco to south of the High Atlas Mountains and northern Tunisia (Fig. 10) (Šrámek et al., 2013; Puechmaille et al., 2012b; this study); however, these individuals were originally referred to as M. schreibersii. Based on these data and the current extent of Miniopterus distribution in the region (Aulagnier & Destre, 1986; Kowalski & Rzebik-Kowalska, 1991; Dieuleveut et al., 2010; Puechmaille et al., 2012b), we present a hypothetical distribution map of both species. Nevertheless, all previous records of M. schreibersii from the Maghreb need to be re-evaluated as they could potentially belong to M. maghrebensis sp. nov. since both species are found in the region (Bilgin et al., submitted).
