Description and diagnosis

Small bat and medium-sized to small representative of the genus Asellia Gray, 1838 . It is in most respects very similar to the other species of the genus, including the structure of the nose leaf (Fig. 11). In body and skull size, A. arabica sp. nov. clearly differs from both the largest and the smallest species of the genus, A. tridens (Geoffroy, 1813) and A. patrizii De Beaux, 1931 , respectively, but it partly overlaps with A. italosomalica De Beaux, 1931 ( Table 1 , Figs. 2 and 4 ). Forearm length 43.1–46.5 mm, condylocanine length of skull 14.2–15.3 mm, length of the upper tooth- row 5.7–6.1 mm. Asellia arabica sp. nov. has a relatively narrow skull (width across the zygomatic arches 8.7–9.3 mm; relative zygomatic width, LaZ/LCc, 0.589 –0.622) and a relatively narrow and short ros-trum (width of rostrum across canines 4.4–4.8 mm; relative width of rostrum across canines, CC/LCc, 0.297 –0.324) in comparison to the other Asellia species; the skull and rostrum of A. arabica sp. nov. are, on average, the narrowest, and the rostrum is the shortest, relatively speaking. The braincase is low (height of braincase 4.7–5.1 mm; relative height of braincase, ANc/LCc, 0.320 –0.342) and the tympanic bullae are rather large (largest horizontal diameter of bulla 2.6–2.9 mm; relative size of bulla, LBT/LCc 0.181 –0.214).

The baculum of A. arabica sp. nov. is a tiny bone, 1.0– 1.3 mm long, with a very narrow distal epiphysis, 0.1–0.2 mm wide (<18% of the baculum length) and a rather narrow proximal epiphysis that is 0.3–0.4 mm wide (<30% of the baculum length) ( Fig. 6l–n ).

The colouration of the dorsal pelage of A. arabica sp. nov. is beige or pale-brownish grey (Fig. 11) with yellowish or pale rusty tinges; the ventral pelage is somewhat paler than the dorsal colouration. The nose leaf is almost unpigmented to very pale brownish; often the anterior leaf is slightly pigmented while the posterior leaf and supplementary leaflets are unpigmented. The wing membranes are pale brownish-grey.

Dimensions of the holotype: see Table 3 .

Genetics: Asellia arabica sp. nov. showed unique base positions within the mitochondrial gene for cytochrome b (1140 bp) at 24 sites: 486, 636, 681, 696, 750 (A→G), 201, 507 (C→A), 1092 (C→G), 145, 282, 492, 504, 690, 915, 958, 963, 1020, 1044 (C→T), 981, 1080, 1093 (T→C), 510, 717 (A/T→C), and 498 (G/T→C). At two sites, 324 and 609, uniquely different positions of Ginstead of A (A→G, A→A/G, and A→G/A) were present in three known haplotypes (DF1, DF2, DF3; see Appendix II). Asellia arabica sp. nov. was found to share identical unique base positions within the gene for cytochrome b with A. tridens (Geoffroy, 1813) at 88 sites: 18, 27, 105, 153, 237, 330, 357, 466, 582, 697, 709, 720, 807, 870, 933, 936, 945, 996, 1038, 1057, 1119 (A), 45, 57, 81, 84, 114, 165, 195, 204, 297, 315, 321, 329, 435, 438, 465, 477, 480, 519, 546, 564, 567, 589, 592, 618, 621, 624, 648, 687, 693, 699, 708, 713, 774, 789, 804, 831, 834, 840, 852, 858, 882, 888, 894, 916, 1126 (C), 129, 178, 372, 476, 591 (G), 66, 121, 126, 246, 285, 288, 345, 351, 399, 474, 528, 792, 897, 906, 999, 1077, and 1122 (T); and with A. italosomalica De Beaux, 1931 at 16 sites: 123, 864, 909, 984, 1023, 1116 (A), 174, 441, 447, 555, 663, 921, 1110 (C), 1017 (G), 684, and 828 (T).

Derivatio nominis

The name arabica (Arabian) reflects the area of occurrence of the new species, i.e. the southern part of Arabia.

Distribution

Coastal areas of southern Arabia stretching from the Hadramaut Province in south-eastern Yemen (ca. 49°E) to the Dhofar Province in south-western Oman (ca. 55°E), i.e., ca. 650 km of a narrow coastal strip.
