D��nyi, L., Erőss, Z., Feh��r, Z., Kontsch��n, J., Mur��nyi, D. (10 females, 2 males). Diagnosis. Peritrematal shield with posterolateral tips reaching level of R 5. Podonotal central and submarginal setae smooth except j 1. Setae S 1 pilose, other marginal R-setae smooth, thorn-like. Setae J 1, Z 1 and S 2 smooth and needle-like, other opisthonotal setae variably pilose. Setae S 2 inserted on a line connecting S 1 and Z 1, equidistantly. Glands gdS 2 (Po 2) situated on a line connecting S 2 and Z 2, gdZ 3 (Po 3) medial to line connecting Z 3 and Z 4. No opisthonotal setae reaching bases of the following setae. Opisthonotum covered by small, distinct alveolar pits, anterior surface reticulate. Outer pair of dorsal cavities twice as big as inner pair. Description. Female. Length of idiosoma: 332���350 ��m (342 ��m); width: 262���274 ��m (267 ��m) (n = 10). Holotype: length: 338 ��m; width: 268 ��m. Dorsal idiosoma (Fig. 16). Podonotum with 20 pairs of setae, j 1-6, z 2-6, s 1-6, r 2 and r 4-5 inserted dorsally, r 1 and r 3 inserted ventrally, on peritrematal shields. Podonotal setae j 1, z 3, s 2-3, r 2, r 4-5 and s 6 densely plumose, brush-like, other setae on the shield short, smooth and needle-like. Glands gds 1 (po 1) situated anteromedial to insertions of s 1; gdj 4 (po 2) situated on line connecting j 4 and z 4; gds 4 (po 3) lateral to line connecting s 4 and s 5. Podonotal shield covered by reticulate pattern, with small pits on its central and posterior surface. Opisthonotum with 21���23 pairs of setae, J 1-5, Z 1-5, S 1-5, marginal R-series with six to eight pairs of setae, seven pairs in majority of specimens. Setae J 1, Z 1 and S 2 similar in shape and length, short, smooth and needlelike. Setae J 2-5 and Z 2-4 short, finely pilose and pointed. Setae S 1 similar to marginal setae of podonotum, densely pilose. Setae S 3-5 and Z 5 twice as long as central opisthonotal setae, brush-like and plumose. Setae S 3���5 reaching beyond margin of opisthonotum. Setae S 2 situated on line connecting S 1 and Z 1, equidistantly. Marginal R-setae short, smooth and thorn-like. No opisthonotal setae reaching bases of the following setae of the series. Setae S 2 situated near Z 1, in posterolateral position. Length of opisthonotal setae and distances between their insertions as in Table 6. Glands gdZ 1 (Po 1) situated anterolateral to insertions of Z 1; gdS 2 (Po 2) situated on line connecting S 2 and Z 2, closer to S 2; gdZ 3 (Po 3) medial to line connecting Z 3 and Z 4; gdS 5 (Po 4) near S 5, in medial position. Whole opisthonotal shield covered by small, alveolar pits, anterior surface with reticulate pattern to level of J 2 -Z 2. Dorsal cavities well-developed, lateral pair strongly sclerotised, twice as large as less-sclerotised medial pair. Ventral idiosoma (Fig. 17). Slit between peritrematal shield and dorsal shields inconspicuous. Peritrematal shield with posterolateral tips reaching level of R 5, covered by fine reticulation. Peritremes slightly bent anteriorly. Chaetotaxy and poroidotaxy of ventral shields typical for genus Prozercon. Sternal shield well sclerotised, 50 ��m long and 40 ��m wide at the level of setae st 2, with straight posterior margin and reticulate ornamentation. Ventrianal shield with short, smooth and needle-like preanal and adanal setae, setae ZV 1 absent. Postanal seta longer than preanal and adanal setae, smooth or finely serrate distally, setae JV 5 brush-like, plumose. Anal valves with vestigial euanal setae. Glands gv 3 situated anterolateral to adanal setae. Anterior surface of ventrianal shield covered by squamous pattern to level of JV 3 -ZV 4 -JV 4. Male (Figs 18���19). Length of idiosoma: 257���268 ��m (263 ��m); width: 200���208 ��m (203 ��m) (n = 10). Chaetotaxy, poroidotaxy and sculptural pattern of dorsal, ventrianal and peritrematal shields similar to those of female, except setae j 2 often delicately barbed. Length of opisthonotal setae and distances between their insertions as in Table 6. Sternigenital shield well-sclerotised, bearing four pairs of setae. Peritrematal shield laterally fused to ventrianal shield, the membranous slit between dorsal and ventral shields lacking. Etymology. The species name ��� dramaensis ��� refers to Drama county (Greece), where the specimens were collected. Remarks. The new species is closely related to Prozercon buraki Urhan, 2008 on the basis of the smooth central podonotal setae and unaequal dorsal cavities. The two species can be distinguished by the characters listed in Table 7.
