Setae j5 short, smooth and needle-like, other podonotal setae pilose. Setae j2-6, s1, s4-5, z2, z4-6 pointed, j1, z3, s2-3, s6, r2, r4-5 brush-like. Among marginal setae, s2, shorter than submarginal setae, r2 and r4-5 approximately as long as submarginal setae, j1, z3, s3 and s6 longer than other podonotal setae. Glands gds1 (po1) situated posteromedial to insertions of s1; gdj4 (po2) situated anteromedial to z4; gds4 (po3) on a line connecting s4 and s5. Podonotal shield covered by reticulate pattern, posterior surface with small, alveolar pits.

Setae J1-2 not reaching insertions of the following setae of the series, J3-4 reaching insertions of the following setae of the series. Setae J5 reaching beyond margins of opisthonotum. Setae S2 inserted lateral to line connecting Z1 and Z2, equidistantly. Bases of central opisthonotal setae medium-sized. Length of opisthonotal setae and distances between their insertions as in Table 12.

Whole opisthonotal shield covered by relatively small, distinct, irregular pits. Dorsal cavities uniform, weakly developed.

Ventral idiosoma ( Fig. 35 ). Peritrematal shield separated from dorsal shields by a narrow membranous slit, with posterolateral tips reaching level of R1, covered by fine reticulation. Peritremes very slightly bent. Chaetotaxy and poroidotaxy of ventral shields typical for genus Prozercon . Sternal shield well sclerotised, 59 μm long and 43 μm wide at the level of setae st2, with straight posterior margin and reticulate ornamentation. Ventrianal shield with short, smooth and needle-like preanal and adanal setae, setae ZV1 absent. Postanal seta distally serrate, longer than preanal and adanal setae, setae JV5 similar in shape to setae S1, plumose. Anal valves with euanal setae. Glands gv3 situated anterolaterally to adanal setae. Anterior surface of ventrianal shield covered by squamous pattern to level of JV3-ZV3-JV4.

Etymology. The new species is dedicated in honor of my dear friend, Nóra Cieleszky.

Remarks. The new species belongs to the group characterised by the following features: majority of podonotal setae pilose; setae S1 plumose; S-series complete; setae S3-5 brush-like, extending beyond margin of opisthonotum; glands gdZ3 (Po3) situated medial to line of Z-series. Prozercon halaskovae Petrova, 1977b matches the first four criteria, however the situation of pores gdZ3 is currently unknown. Distingushing characters of the three species of the group ( Prozercon norae sp. nov., Prozercon dominiaki Błaszak, 1979a and Prozercon kamili Urhan & Ayyildiz, 1996c ) and the morphologically similar Prozercon halaskovae are presented in Table 13 .
