Type material. Holotype: adult female on slide: Israel: Nahal Keziv, Quercus calliprinos forest, litter, N slope, 16.ii. 1999, leg. T. Pavliček, ZIWU. Paratype: juvenile on slide, same data as holotype, MNHL.
Etymology. The species name refers to the historic name of the Near East.
Diagnosis. Habitus typical of the genus Endonura . Dorsal tubercles present and well developed, except tubercles Di on th. I. 2 + 2 dark-pigmented eyes. Buccal cone rather short. Head with chaetae A, B, C, D and E. Chaeta O present or absent. Tubercles Dl and (L+So) on head with 6 and 8 chaetae respectively. Tubercles De on th. II and III with 3 and 4 chaetae respectively. Tubercles L on abd. III and IV with 3 and 5–6 chaetae respectively. Abd. IV and V with 8 and 3 tubercles respectively. Claw without inner tooth. Tibiotarsi with chaetae B 4 and B 5 short.
Description. Habitus typical of the genus. Body length (without antennae): holotype 0.84 mm, paratype (first instar) 0.77 mm. Colour of the body white. 2 + 2 medium dark-pigmented eyes ( Fig. 1 View Figure ).
Types of dorsal ordinary chaetae. Macrochaetae Ml relatively long, strongly thickened, almost cylindrical, arclike or straight, narrowly sheathed, feebly serrated, apically rounded or rarely pointed (mostly in lateral part of body) ( Figs 1, 5, 8–10 View Figure ); macrochaetae Mc and Mcc thickened, straight and blunt; mesochaetae and microchaetae short, thin, feebly serrated and pointed.
Head. Buccal cone short. Labrum rounded, with ventral sclerifications as in Fig. 4 View Figure . Labrum chaetotaxy 0?/ 2, 4, prelabral chaetae not seen. Labium with four basal, three distal and four lateral chaetae, papillae x absent. Maxilla styliform ( Fig. 3 View Figure ), mandible thin tridentate ( Fig. 2 View Figure ). Chaetotaxy of antennae as in Tab. 2 c and in Fig. 6 View Figure . Apical vesicle distinct, trilobed. S–chaetae of ant.IV of medium length and moderately thickened, S 3 thinner than others ( Fig. 6 View Figure ). Chaetotaxy of head as in Tab. 1 a, b, and Fig. 1 View Figure . Tubercles Cl and Af separate ( Fig. 1 View Figure ). Chaeta O present or absent. Chaetae D and E free. Tubercle Dl with 6 chaetae, chaeta Dl 3 present ( Fig. 1 View Figure ). Tubercle (L+So) with 8 chaetae, chaetae So 3 and L 3 absent ( Fig. 1 View Figure ). Elementary tubercle BE absent. Chaeta A shorter than B.
Thorax, abdomen, legs. Body s-chaeta thin and smooth, distinctly shorter than nearby macrochaetae ( Figs 5, 8 View Figure ). Chaetotaxy of th. and abd. as in Tab. 1 d and in Figs 5, 7–10 View Figure . Tubercles Di on th.I not differentiated. Chaetae De 3 on th. III and abd. I–III as minute microchaetae. Chaetae De 2 on th. II–III and De 3 on th. III connected with tubercle De. Chaetae De 3 on abd. I–III connected with tubercle De ( Fig. 8 View Figure ). The line of chaetae De 1 –chaeta s perpendicular to the dorsomedian line on abd. I–IV. Tubercle L on abd. III and IV with 3 and 5–6 chaetae respectively ( Fig. 5 View Figure ). Furca rudimentary with 7–8 microchaetae ( Fig. 7 View Figure ).Tubercles Di on abd. V fused, with chaetae Di 2 as Mc and Di 3 as very small mi ( Fig. 9 View Figure ). Chaetae L' and Vl on abd. V present. No cryptopygy. Chaetotaxy of legs as in Tab. 1 d. Tibiotarsi with chaetae B 4 and B 5 short. Claw without inner tooth.
Discussion. In general appearance (shape of dorsal chaetae, chaetotaxy of central area of head and dorsal side of thorax and abdomen), E. levantica resembles two Spanish species, namely E. gladiolifer ( Cassagnau, 1954) and E. alavensis ( Pozo & Simón, 1981) . Differences beetwen E. levantica and the outlined taxa include the number of chaetae on head tubercle (L+So) (in levantica 8, in gladiolifer 10, in alavensis 8–9), number of chaetae L on abd.
III (in levantica 3, in gladiolifer and alavensis 4), number of chaetae L on abd. IV (in levantica 5–6, in gladiolifer and alavensis 7), number of ordinary chaetae on tubercle (De+Dl+L) of abd. V (in levantica 5, in gladiolifer and alavensis 6–7), number of microchetae on furca rudimentary (in levantica 8, in gladiolifer 2–4, in alavensis 6) and the lenght ratio of chaetae Di 1:Di 2:Di 3 of abd. V (in levantica 44: 11: 2, in gladiolifer 18: 10: 2, in alavensis 37: 10: 3–7, Jordana et al. 1997).
