status

sp. nov.

Cunaxa maculata  sp. nov.

Female ( Figs. 19–26View FIGURES 19 – 22View FIGURES 23 – 26 & 55, 56View FIGURES 54 – 58).

Gnathosoma ( Figs. 19, 20View FIGURES 19 – 22). Chaetotaxy and structure of palps ( Fig. 19View FIGURES 19 – 22) and chelicerae ( Fig. 20View FIGURES 19 – 22) as in C. gordeevae  sp. nov. Dorsal seta of basifemur filiform. The latter is more thin than dorsal setae on genu and telofemur. Apophysis of telofemur cone-like, with pointed apex, situated distally on the segment. Ventral surface of hypognathum with numerous papillae, coxal part with internal apodemes which form oval-shaped cells.

Idiosomal dorsum ( Figs. 21View FIGURES 19 – 22 & 55, 56View FIGURES 54 – 58). Chaetotaxy as in C. gordeevae  sp. nov. Main part of propodosomal plate smooth, but near bases of vi and sce some papillae occur, and there is an oval area near sci, formed by short broken striae ( Fig. 55View FIGURES 54 – 58). Central part of hysterosoma with thin, distinctly lobed (=with festoons) striae ( Fig. 56View FIGURES 54 – 58). Lateral parts of idiosoma with papillated striae.

Idiosomal venter ( Fig. 22View FIGURES 19 – 22). Ventral surface with thin, broken striae, which in the anogenital region is papillated. Chaetotaxy as in C. gordeevae  sp. nov. Borders of genital valves vaguely discernable, their surface with numerous papillae. Genital setae subequal in length.

Legs ( Figs. 23–26View FIGURES 23 – 26). 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}, {2 asl} 1 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, 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. 23View FIGURES 23 – 26). In holotype as well as in a single paratype the proximal solenidia on genu I are in a duplex association. On tibia II ( Fig. 24View FIGURES 23 – 26) of both types the dorsal simple seta and the solenidion are also in duplex association. Leg surface and structure of segments as in C. gordeevae  sp. nov.

Measurements. Length of idiosoma 328 (305); width 239 (211). Length of hypognathum 149 (141); width 82 (76). Length of palps 170 (165). Length of chelicerae 134 (126). Length of legs: I 277 (267); II 258 (256); III 296 (290); IV 319 (310). Length of setae: hg 1 15 (17); hg 2 21 (21); hg 3 33 (31); hg 4 23 (22); ve 12 (11); sci 20 (20); c 1 22 (22); c 2 18 (17); d 1 21 (20); e 1 21 (19); f 1 37 (34); h 1 39 (36); g 1–4 12–14 (12–14). Distance between setae: sci –sci 33 (30).

Male and immatures unknown.

Etymology. The specific name maculata  (from Latin: macula = stain) refers to presence of oval area of broken striae on the dorsal propodosomal plate near setae sci.

Differential diagnosis. This species differs from all known species of the genus, and the closely related C. papuliphora  sp. nov., by the presence of an oval area of broken striae on the dorsal propodosomal plate near setae sci.

Type material. Female holotype, Ukraine, Crimea, vicinity of settlement Morskoye, in soil under oak Quercus pubescens  , 15.X. 2005 (Coll. Sergeyenko, A.L.). Paratype: 1 Ψ, with same data as holotype.
