Cunaxa violaphila   sp. nov.

Female ( Figs. 35 View FIGURES 35 – 40 –44 & 58).

Gnathosoma ( Figs. 35–38 View FIGURES 35 – 40 ). Chaetotaxy and structure of palps ( Fig. 35 View FIGURES 35 – 40 ) and chelicerae ( Fig. 36 View FIGURES 35 – 40 ) as in C. gordeevae   sp. nov. Basi- and telofemur of palps with filiform dorsal setae, genu with incrassate dorsal setae. Apophysis of telofemur cone-like with dull apex, situated proximomedially on joint. Dorsally the hypognathal coxal region possesses an oval-shaped papillated area which joins with the broken striae of ventral surface of hypognathum ( Fig. 37 View FIGURES 35 – 40 ). Ventral surface of hypognathum as in Fig. 38 View FIGURES 35 – 40 .

–. Cunaxa violaphila   , female. Genu, tibia and tarsus (without ambulakrum) of: leg I (); leg II (42); distal part of telofemora, genu, tibia and tarsus (without ambulakrum) of: leg III (43); leg IV (44). Scale-bar— 50 μm.

Idiosomal dorsum ( Fig. 39 View FIGURES 35 – 40 & 58 View FIGURES 54 – 58 ). Chaetotaxy as in C. gordeevae   sp. nov. Propodosomal plate mainly smooth, and only near the bases of setae vi and laterally to sce provided with some papillated regions. Also, the anterior region of the plate with faint striae ( Fig. 39 View FIGURES 35 – 40 ). Length of setae sci much longer than the half distance between their bases. Setae f 1 and h 1 distinctly setose. Relative length of dorsal hysterosomal setae: f 1 = h 1 ˃ c 1 = d 1 = e 1 ˃ c 2. The hysterosomal dorsum with thin, long striae without lobes and papillae ( Fig. 58 View FIGURES 54 – 58 ).

Idiosomal venter ( Fig. 40 View FIGURES 35 – 40 ). Striae of the idiosomal venter are long, thin and smooth. Chaetotaxy as in C. gordeevae   sp. nov. Genital valves with longitudinal striae. Genital setae subequal in length. Distance between setae g 2 –g 3 longer than distance g 1 –g 2 and g 3 –g 4.

Legs (Fig. 41–44). Leg chaetotaxy: coxae I –IV, 3 sts, 1 peg — 1 sts — 3 sts — 2 sts; trochanters I –IV, 1 — 1—2 — 1 sts; basifemora I –IV, 4 — 4 — 3 —0 sts; telofemora I –IV, 4 sts — 4 sts — 3 sts, 1 ms — 3 sts, 1 ms; genua I –IV, {2 asl, 1 sts}, {2 asl}, 4 sts — 2 asl, 5 sts — 1 asl, 5 sts — 1 asl, 5 sts; tibiae I –IV, {1 asl, 1 sts}, 1 bsl, 4 sts — 1 bsl, 5 sts — 1 bsl, 5 sts — 1 T, 4 sts; tarsi I –IV, {1 bsl, 1 peo, 1 sts}, 3 bsl, 1 dtsl, 2 tsl, 21 sts — 1 bsl, 1 dtsl, 1 tsl, 22 (21) sts — 1 tsl, 22 (23) sts — 19 (20) sts. The surface of basifemora with transverse broken striae; that of other segments with elongate papillae which are dorsally longer and less dense than ventrally.

Measurements. Length of idiosoma 338 (338–408); width 225 (235–272). Length of hypognathum 131 (131–136); width 77 (77–83). Length of palps 185 (185–203). Length of chelicerae 118 (118–130). Length of legs: I 244 (239–253); II 228 (225–239); III 253 (249–267); IV 281 (272–295). Length of setae: hg 1 17 (17–19); hg 2 21 (21–25); hg 3 34 (33–40); hg 4 20 (19–22); ve 12 (11–13); sci 32 (30–37); c 1 34 (30–37); c 2 28 (23–30); d 1 32 (23–33); e 1 31 (24–33); f 1 55 (53–61); h 1 54 (51–57); g 1–4 14–15 (13–17). Distance between setae: sci –sci 34 (35–39).

Remark. Number of simple setae on tarsi II –IV may vary between 22 – 21, 22–23 and 19–20 respectively.

Male and immatures unknown.

Etymology. The specific name violaphila   (from Latin: viola   = violet, and Hellenic: phila = to like) refers to the distribution of this new species on the leaves of violets.

Differential diagnosis. See differential diagnosis of Cunaxa yaylensis   sp. nov.

Biology. In laboratory on leaves of violet Viola   sp. C. violaphila   could ambush in web on tetranychid mites, Tetranychus   sp.
