description
Female (Figure 4). Length of idiosoma in holotype 461, width 309. Measurements in female paratypes: mean length 458 (447 – 469), mean width 309 (298 – 309) (n = 10). Dorsum (Figure 4). Nineteen pairs of setae present on podonotum: j-row with six pairs, z-row with two pairs, s-row with five pairs and r-row with six pairs. All setae on podonotum smooth. Seta s 1 absent. Setae in r series slightly longer than other setae on podonotum. Twenty-two pairs of setae present on opisthonotum: J-row with six pairs, Z-row with five pairs, S-row with four pairs and R-row with seven pairs. All setae on opisthonotum smooth. Only setae J 4 and J 5 reach beyond base of following setae in the series. Seta Z 3 reach to base of seta Z 4, seta Z 4 reach beyond base of seta Z 5. Seta S 2 reach to edge of opisthonotum, seta S 3 reach beyond opisthonotum. Podonotum and opisthonotum covered with indistinct pattern. Dorsal cavities distinct, equal in size, well sclerotised, axes parallel to that of the body. Pores (Figure 4). Pore po 1 located on line connecting setae j 2 - s 2, pore po 2 inside line connecting setae j 4 - s 4 (closer to seta s 4) and pore po 3 outside of line connecting setae j 5 - s 6 (closer to seta j 5) on podonotum. Pore Po 1 above the base of seta Z 1, pore Po 2 outside line connecting setae Z 2 - S 1 (closer to seta Z 2), pore Po 3 located on line connecting setae J 4 - Z 4, pore Po 4 above the base of seta Z 5 on opisthonotum. Venter. Shapes of ventral shields and peritremes, chaetotaxy are typical for genus Zercon. Two pairs of setae present on ventral side of podosoma. Setae p 1 short, smooth and needle-like, seta p 2 markedly elongated and smooth (not finely barbed, without hyaline ending). Peritremes slightly bent. Lateral ends of peritremal shields reach seta R 1. Adgenital shields present (with 3 – 5 opening valves). Ventrianal shield with nine pairs of setae. Anterior margin of ventrianal shield with four setae and unpaired postanal seta, all short, smooth and needle-like. Male (Figure 5). Mean length of idiosoma 376 (371 – 382), mean width 243 (236 – 248) (n = 10). Dorsal side, ventral side, shape of setae on idiosoma, sculpture of podonotum and opisthonotum, size and appearance of dorsal cavities basically similar to those of female. Deutonymph. Mean length of idiosoma 403 (392 – 412), mean width 252 (243 – 265) (n = 10). All setae smooth on podonotum and opisthonotum. Protonymph. Mean length of idiosoma 326 (316 – 336), mean width 195 (187 – 202) (n = 2). All setae smooth on podonotum and opisthonotum.
discussion
Remarks. Average lengths of opisthonotal setae and distances between setae within longitudinal rows of females, males, deutonymphs and protonymphs specimens: see Table 1. Zercon filiformis sp. nov. is closely related to Z. bulgaricus Balogh, Z. cabylus Athias-Henriot and Z. bercziki Ujvári. The distinguishing characters of these four species are shown in Table 2.
etymology
Etymology. The name of this new species, filiformis, refers to the shapes of the setae on the opisthonotum.
