sp. nov.

Cunaxa papuliphora   sp. nov.

Female ( Figs. 27–34 View FIGURES 27 – 30 View FIGURES 31 – 34 & 57 View FIGURES 54 – 58 ).

Gnathosoma ( Figs. 27, 28 View FIGURES 27 – 30 ). Chaetotaxy and structure of palps ( Fig. 27 View FIGURES 27 – 30 ) and chelicerae as in C. gordeevae   sp. nov. Dorsal setae on basifemur filiform, telofemur and genu with slightly incrassate dorsal setae. Apophysis of telofemur cone-like, with pointed apex and attached to the distal margin of segment. Ventral surface of hypognathum papillated; coxal region with internal apodemes ( Fig. 28 View FIGURES 27 – 30 a). There is a smooth area in the region of setae hg 3, separated into two parts by stripes of small papillae.

Idiosomal dorsum ( Fig. 29 View FIGURES 27 – 30 & 57 View FIGURES 54 – 58 ). Chaetotaxy and structure of propodosomal plate as in C. gordeevae   sp. nov. Length of setae sci more than half the distance between their bases. Relative length of dorsal hysterosomal setae: f 1 = h 1 ˃ c 1 = d 1 = e 1 ˃ c 2. Hysterosomal striae thin and distinctly lobed (=with festoons) ( Fig. 57 View FIGURES 54 – 58 ).

Idiosomal venter ( Fig. 30 View FIGURES 27 – 30 ). Chaetotaxy of idiosomal venter as in C. gordeevae   sp. nov. Propodogastral setae situated on small platelets. Genital valves with small papillae which form longitudinal rows.

Legs ( Figs. 31–34 View FIGURES 31 – 34 ). 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, 3 — 3 — 3 — 1 sts; telofemora I –IV, 4 — 4 — 4 — 4 sts; genua I –IV, {1 asl, 1 sts}, 3 asl, 4 sts — 2 asl, 5 sts — 1 asl, 5 sts —asl, 5 sts; tibiae: I –IV, {1 asl, 1 sts}, 1 bsl, 4 sts —{1 bsl, 1 sts}, 4 sts — 1 bsl, 5 sts — 1 T, 4 sts; tarsi I –IV, {1 bsl, 1 peo, 1 sts}, 3 bsl, 1 dtsl, 2 tsl, 23 sts — 1 bsl, 1 dtsl, 1 tsl, 25 sts — 1 tsl, 26 sts — 21 sts. One of two proximal solenidia on genu I is extremely short, its length as long as the diameter of its alveoli ( Fig. 31 View FIGURES 31 – 34 ). Leg surface and structure of segments as in C. gordeevae   sp. nov.

Measurements. Length of idiosoma 352 (330–390), width 253 (230–270). Length of hypognathum 154 (144–157), width 87 (82–87). Length of palps 175 (170–177). Length of chelicerae 141 (139–146). Length of legs: I 263 (258–286); II 244 (244–258); III 272 (277–291); IV 296 (296–319). Length of setae: hg 1 14 (13–16), hg 2 20 (17–20), hg 3 33 (29–35), hg 4 21 (16–22), ve 12 (11–14), sci 24 (21–24), c 1 22 (21–23), c 2 18 (19–21), d 1 22 (20–23), e 1 23 (20–24), f 1 36 (35–39), h 1 40 (34–40), g 1–4 11–14 (11–14). Distance between setae: hg 4 –hg 4 32 (30–33), sci –sci 34 (30–34), ve –ve 103 (96–106), sce –sci 38 (36–40).

Remarks. In some specimens the proximal solenidia on genu I are in a duplex association.

Male and immatures unknown.

Etymology. The specific name papuliphora   (from Latin: papuli = heat-spots and Hellenic: phor = bearing) refers to characteristic lobed structure of striae on hysterosomal dorsum.

Differential diagnosis. This new species closely resembles С. maculata   sp. nov., but differs by the absence of an oval area of broken striae on dorsal propodosomal plate near setae sci.

Biology. Some of the biological peculiarities C. papuliphora   sp. nov. were studied in the laboratory on leaves of violet Viola   sp. In laboratory this mite species could feeding on tetranychid mites, Tetranychus   sp. ( Tetranychidae   ). Cunaxa papuliphora   were actively searching for prey. Cannibalism were observed in C. papuliphora   .
