Material examined (Fig. 39). E- 2556, Greece, Arkadia county, Elliniko, Platanus forest south of the Gortis ruins, 380 m a.s.l., N 37 ° 32.020 ’E 22 °03.191’, 06.04.2009, leg. Dányi, L., Kontschán, J., Murányi, D. (3 females, 1 DN).
Diagnosis
Diagnosis. Peritrematal shield with posterolateral tips reaching level of R 1. Dorsal podonotal setae pilose except j 5 which is smooth. Marginal R-setae smooth, thorn-like, other opisthonotal setae plumose. Setae S 2 inserted on a line connecting Z 1 and Z 2, equidistantly. Setae S 4 absent. Glands gdS 2 (Po 2) situated medially to a line connecting S 2 and Z 2, gdZ 3 (Po 3) anteromedially to insertions of Z 4. Setae J 3 -J 4 reaching bases of the following setae.
Description
Description.Female. Length of idiosoma: 342–350 μm (346 μm); width: 235–240 μm (238 µm) (n = 3).
Dorsal idiosoma (Fig. 5). Podonotum with 20 pairs of setae, j 1-6, z 2-6, s 1-6, r 2 and r 4-5 inserted dorsally, setae r 1 and r 3 inserted ventrally, on peritrematal shields. Podonotal setae densely plumose except j 5 short, smooth and needle-like. Setae j 2-6, s 1, s 4-5, z 2, z 4-6 pointed, j 1, z 3, s 2-3, s 6, r 2, r 4-5 brush-like; s 2, r 2 and r 4 shorter than other brush-like marginal setae. Glands gds 1 (po 1) situated posteromedially to insertions of s 1; gdj 4 (po 2) situated anteromedially to z 4; gds 4 (po 3) on line connecting s 4 and s 5. Podonotal shield covered by reticulate pattern, posterior surface with distinct alveolar pits. Opisthonotum with 20–21 pairs of setae, J 1-5, Z 1-5, S 1-5, marginal R-series with five or six pairs of setae, six pairs in majority of specimens. Setae J 1-5, Z 1-4 and S 2 similar in shape and length, densely pilose, pointed. Setae Z 5, S 3 and S 5 brush-like, plumose, extending beyond margin of opisthonotum. Setae S 1 plumose, twice as long as short, smooth and thorn-like R-setae. Setae S 4 absent. Setae J 1-2 not reaching insertions of the following setae, J 3– 4 reaching insertions of the following setae of the series. Setae J 5 reaching beyond margins of opisthonotum. Setae S 2 inserted on line connecting Z 1 and Z 2, equidistantly. Bases of central opisthonotal setae small to medium-sized. Length of opisthonotal setae and distances between their insertions as in Table 1. Glands gdZ 1 (Po 1) situated anteromedially to insertions of Z 1; gdS 2 (Po 2) medially to line connecting S 2 and Z 2; gdZ 3 (Po 3) anteromedially to insertions of Z 4; gdS 5 (Po 4) medially to S 5. Whole opisthonotal shield covered by relatively large, distinct, irregular pits. Dorsal cavities uniform, weakly developed.

Peritrematal shield separated from dorsal shields by a narrow membranous slit, with posterolateral tips reaching level of R 1, covered by fine reticulation. Peritremes straight. Chaetotaxy and poroidotaxy of ventral shields typical for genus Prozercon. Sternal shield well sclerotised, 54 μm long and 43 μm 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 on anterior margin of the shield. Postanal seta longer than preanal and adanal setae, distally serrate, setae JV 5 similar to R-setae, short, smooth and thorn-like. Anal valves with euanal setae. Glands gv 3 situated anterolaterally to adanal setae. Anterior surface of ventrianal shield covered by squamous pattern to level of JV 3 -ZV 3 -ZV 4. Deutonymph (Fig. 7). Length of idiosoma: 306 μm; width: 215 μm (n = 1). Podonotal setae j 1, z 3, s 3 and s 6 markedly elongate, brush-like, plumose. Marginal setae s 2, r 2 and r 4 short, barbed. Setae j 2, j 6, s 1, z 2, z 4, s 4, s 5 and z 6 similar in shape and length, densely pilose, pointed. Setae j 4 and z 5 finely pilose, j 3 and j 5 smooth and needle-like. Position of gland pores as for the female. Opisthonotal shield covered by weakly-developed, serrulate reticulation. Opisthonotal chaetotaxy and poroidotaxy as for the female, setae S 1 similar in length to marginal R-setae. Length of opisthonotal setae and distances between their insertions as in Table 1. Whole surface of opisthonotum covered by small, irregular pits.
Discussion
Remarks. This species has been collected in the Aegean region of Turkey (Urhan, 1998 a), and in Crete (Ujvári, 2008). Setae JV 5 are plumose and the peritrematal shields are expanded to the level of setae R 2 on specimens from the Aegean region of Turkey, while JV 5 are smooth and needle-like, peritrematal shields are expanded only to level of S 1 on the ones collected on the Peloponnesos.
