Figs 38–49, Tab. 4
Material examined. Type material. Holotype, adult female on slide, leaf litter on mountain meadow, Nikits’kyi Pereval, ca. 1450 m a.s.l., neighborhood of Jalta, Crimea, Ukraine, 12.ix.1997, leg. R. J. Pomorski, D. SkarŻyński, I. Kaprus’. Paratypes: 3 males, 2 females and juvenile on slides, the same data as holotype (holotype and 2 paratypes ZIWU, 4 paratypes MNHL).
Number of other cephalic chaetae: Vi, 6; Ve, 10–11; labrum, 4/2, 4; labium, 11, 0x; ant. I, 7; ant.II, 11; ant. III, 18+5s; ant. IV, 8S+i +or+12mou.
b) Postcephalic chaetotaxy.
Diagnosis. Habitus typical of the genus Endonura. Dorsal tubercles present, well developed. 2+2 eyes present. Buccal cone elongated. Labral chaetotaxy 4/2, 4. Mandible thin with 5 teeth. Head with 3 chaetae Oc, chaetae A, B, C, D, E (chaeta O absent). Tubercle (L+So) on head with 10 chaetae. Tubercles De on thoracic terga II and III with 3 and 4 chaetae respectively. Tubercles L on abd. III and IV with 4 and 8–9 chaetae respectively. Claw with inner tooth. Tibiotarsi I, II with long chaetae B5 and B4. Tibiotarsus III with only one long chaeta B4.
Etymology. The species name is derived from the Latin words “dens”–tooth and “fero”–wear. The new species has a claw with distinct internal tooth.
Description. Habitus typical of the genus. Body length (without antennae) 1.45–1.95 mm. Colour of the body greyish-blue of variable intensity. 2+2 large, dark-pigmented eyes.
and ventral guard sensillum in antennal III-organ; 32, antennal segments III–IV of right antenna (dorsal view).
Types of dorsal ordinary chaetae: macrochaetae Ml and Mc thickened, narrowly sheathed, feebly serrated and not pointed (Figs 38, 42–44); mesochaetae thin and pointed.
Head. Buccal cone rather long and rounded at apex. Labrum chaetotaxy 4/2, 4, ventral sclerifications nonogival. Chaetotaxy of labium as in Fig. 40 and Tab. 4. Maxilla styliform, mandible thin with 2 basal and 3 apical teeth (Fig. 39). Chaetotaxy of antennae as in Tab. 4. Apical vesicle distinct, trilobed. S-chaetae subequal, long and moderately thickened. Chaetotaxy of head as in Figs 38, 40–41 and Tab. 4. Tubercle Af narrow (Fig. 38), chaeta O absent. Tubercle (L+So) with 10 chaetae (chaeta So2 present, Fig. 41).
Thorax, abdomen, legs. Chaetotaxy of th. and abd. as in Figs 42, 44–45 and Tab. 4. Tubercles Di on th.I not differentiated. Tubercles L on abd. III and IV with 4 and 8–9 chaetae respectively (Fig. 45). Cryptopygy absent. Chaetotaxy of legs as in Figs 46–49 and Tab. 4. Claw with distinct inner tooth (Figs 46–49). Tibiotarsi I and II with elongate and slightly clavate chaetae B5 and B4. Tibiotarsi III with elongate and slightly clavate chaeta B4.
Discussion. The new species is the most similar to E. quadriseta Cassagnau et Péja, 1979, but differs from it in the following characters: tubercle (L+So) on head with chaeta So2 (in quadriseta absent), chaeta O absent (in quadriseta present), claw with inner tooth (in quadriseta absent) and tibiotarsi with elongate and slightly clavate chaetae B4 and B5 (in quadriseta short and not clavate).
Number of other cephalic chaetae: Vi, 6; Ve, 10–11; labrum, 4/2, 4; labium, 11, 0x; ant. I, 8; ant.II, 11; ant. III, 18+5s; ant. IV, 8S+i +or+12mou.
b) Postcephalic chaetotaxy.
