Type material. Holotype: female, bark of Zelkova abelicea trees, slope of Mt. Kedros near Gerakari village (35.194829 N, 24.606713 E), 1255 m a. s. l., Crete, Greece, 11.X.2018, leg. D.J. Gwiazdowicz. GoogleMaps
Description. General. Habitus typical of genus. Dorsal tubercles present and well developed. Body length of holotype (without antennae): 1.25 mm. Colour of the body white in alcohol. 2 + 2 large black eyes, in a typical arrangement for the genus ( Fig. 37 View FIGURES 37–42 ).
Chaetal morphology. Dorsal ordinary chaetae of four types: long macrochaetae (Ml), short macrochaetae (Mc), mesochaetae and microchaetae. Long macrochaetae long, relatively thin, distinctly arc-like ( Anthrenus -like) or straight, narrowly sheathed, feebly serrated, apically pointed ( Figs 37, 41 View FIGURES 37–42 ). Macrochaetae Mc morphologically similar to long macrochaetae, but shorter and usually straight. Mesochaetae similar to ventral chaetae, thin, smooth and pointed. Microchaetae similar to mesochaetae, but apparently short. S–chaetae of tergites thin, smooth and short, notably shorter than nearby macrochaetae ( Fig. 37 View FIGURES 37–42 ).
Antennae. Typical of the genus. Dorsal chaetotaxy of Ant. III–IV as Fig. 44 View FIGURES 43–51 and Tab. 3b View TABLE 3 . S-chaetae of Ant. IV long and relatively thin, sensillum sgd relatively long and straight. Apical vesicle distinct, trilobate. Ventral chaetotaxy of Ant. III and Ant. IV as Tab. 3b View TABLE 3 , sensillum sgv long and slightly curved ( Fig. 43 View FIGURES 43–51 ).
Mouthparts. Buccal cone relatively long and wide, labral sclerifications nonogival ( Figs 38, 40 View FIGURES 37–42 ). Labrum chaetotaxy: 0/2, 2 ( Fig. 40 View FIGURES 37–42 ). Labium as in Fig. 38 View FIGURES 37–42 . Maxilla massive, maxillary capitulum with two apical teeth ( Fig. 48 View FIGURES 43–51 ). Mandible strongly developed with four basal and numerous (more than 10) apical teeth ( Fig. 47 View FIGURES 43–51 ).
Dorsal chaetotaxy and tubercles. Central area of head without chaetae C and O ( Fig. 37 View FIGURES 37–42 , Tab. 3a View TABLE 3 ). Microchaetae D on head free. Tubercles Cl and Af separate. Tubercles Dl and (L+So) on head with 5 and 7 chaetae respectively. Tubercles Di on Th.I with1chaeta each ( Fig.37 View FIGURES 37–42 ).Tubercles Di on Th.II and III with3chaetae,chaetae Di3free( Fig.37 View FIGURES 37–42 ). Tubercles De on Th. II and III with 2+s and 3+s chaetae respectively. Tubercles Di and De on Abd. elongate and weakly prominent. Tubercles L on Abd. III and IV with 3 and 5 chaetae respectively. Tubercles Di on Abd. V with 3 chaetae each. Cryptopygy present and strongly developed, Abd. VI not visible from above ( Fig. 41 View FIGURES 37–42 ).
Ventral chaetotaxy. On head, groups Vea, Vem and Vep with 3–4, 3, 4 chaetae respectively. Group Vi on head with 6 chaetae ( Fig. 38 View FIGURES 37–42 ). On Abd. IV, furca rudimentary with 5 mesochaetae and without microchaetae ( Fig. 49 View FIGURES 43–51 ). On Abd. V, chaetae Vl present.
Legs. Chaetotaxy of legs as in Tab. 3C View TABLE 3 . Claw with strong inner tooth. On tibiotarsi, chaeta M present and chaetae B4 and B5 relatively long and pointed ( Fig. 42 View FIGURES 37–42 ).
Etymology. Dedicated to dr. Willem N. Ellis, who initiated the research on Collembola of Crete.
Remarks. Within the genus Cryptonura , Cryptonura ellisi sp. nov. most closely resembles C. anthrenoidea ( Ellis, 1976) , species described from Crete ( Ellis 1976). In order to compare morphology of both species two paratypes of Ellis’ taxon were examined. The examination showed that the new species and C. anthrenoidea clearly differ in set of many characters: the shape of labral apex (in C. ellisi sp. nov. arc-like, Fig. 40 View FIGURES 37–42 ; in C. anthrenoidea truncated, Fig. 39 View FIGURES 37–42 ), the shape of mandibles (in C. ellisi sp. nov. very strong and thick, Fig. 47 View FIGURES 43–51 ; in C. anthrenoidea slightly thickened, Fig. 46 View FIGURES 43–51 ), the number of mandibular teeth (in C. ellisi sp. nov. four basal and at least ten apical teeth, Fig. 47 View FIGURES 43–51 ; in C. anthrenoidea two basal and four apical teeth, Fig. 46 View FIGURES 43–51 ), the shape of maxillae (in C. ellisi sp. nov. notably thickened, Fig. 48 View FIGURES 43–51 ; in C. anthrenoidea needle-like, Fig. 45 View FIGURES 43–51 ), the number of chaetae d on Ant. III (in C. ellisi sp. nov. three chaetae, Fig. 44 View FIGURES 43–51 ; in C. anthrenoidea four chaetae, Fig. 50 View FIGURES 43–51 ), the number of chaetae (L+So) on the head (in C. ellisi sp. nov. 7 chaetae, in C. anthrenoidea 8 chaetae), the shape of abdominal tubercle Di and De (in C. ellisi sp. nov. elongate and prominent, Fig. 41 View FIGURES 37–42 ; in C. anthrenoidea rounded) and the number of chaetae Vei on Abd. IV (in C. ellisi sp. nov. 2 + 2 chaetae, Fig. 49 View FIGURES 43–51 ; in C. anthrenoidea 1 + 1 chaetae, Fig. 51 View FIGURES 43–51 ).
