Prozercon miraci sp. nov. ( Figs 1-6)

Type material. Holotype (female), soil and litter samples under oak trees ( Quercus sp. ), 39°18.321' N, 27°54.697' E, 395 m, Fırdanlar village of Manisa province, 7 January 2019 . Paratypes: 11 females, 8 males, 6 deutonymphs and 3 protonymphs. All of them were collected from same locality with holotype .

Description. Female. Dorsal site ( Fig. 1). Length (without gnathosoma) and width in holotype 337 and 240, respectively. Measurement of 11 paratypes; length 335–351, width 236–245. Shapes of idiosomal shields were illustrated in Figure 1. Dorsal fossae are clear and well developed. Moreover, outer cavities is 2–4 times larger than inners.

Dorsal setae ( Fig. 1). 20 pairs of various setae present on podonotum: Number of setae in j series with 6 pairs, z series with 2 pairs, s series with 5 pairs and r series with 7 pairs. Setae j 1, r 1, r 4 –r 7 markedly elongated, densely plumose, brush-like and apically rounded. Setae j 4 –j 6 and z 1 short, smooth and needle-like. Remaining podonotal setae pilose or plumose. 23 pairs of various setae present on opisthonotum: Number of setae in J series with 6 pairs, Z series with 5 pairs, S series with 4 pairs and R series with 8 pairs. Setae J 1 –J 5, Z 1 –Z 3, Z 5 and S 1 plumose and apically tapering. Setae J 6, Z 4 and S 2 –S 4 densely plumose, brush-like and apically rounded. Marginal setae R 1 – R 8 short, smooth and thorn-like. Setae J 1 –J 2 not reaching to insertion of following setae in related rows. Setae J 3 and J 4 reaching to insertion of next setae. Setae J 5 not reaching to posterior margin of opisthonotum. The interval between setae J 6 and J 6 is 62–68 apart. None of setae in Z series not reaching the insertion of next setae. Setae Z 4 are the longest of idiosoma and protrudes beyond posterior margin of opisthonotum. The interval between setae Z 5 and J 6 is 29– 32 apart. Setae S 1 not reaching the insertion of setae Z 2. Setae S 2 –S 4 reaching to beyond of lateral margin of opisthonotum.

Pores ( Fig. 1). Pores po 1 are located on the line connecting setae s 1 –j 3 closer to s 1. Pores po 2 are located above the line connecting setae s 3 –j 4 closer to s 3. Pores po 3 are located on the line connecting setae s 4 –s 5. Pores Po 1 are located anteroparaxially to insertion of setae Z 1. Pores Po 2 are located outside the line connecting setae S 1 –Z 2 or located on the line connecting setae S 1 –S 2 closer to S 1. Pores Po 3 are located on the line connecting setae S 3 and Z 4. Pores Po 4 are located on the line connecting setae S 4 –Z 5.

Ventral site ( Fig. 2). Chaetotaxy and shape of the peritrematal shield are characteristical for Prozercon species (Mašán and Fend'a, 2004).

Male ( Figs 3-4). Length of idiosoma in 8 paratypes 272– 290, width 191–203. Chaetotaxy of idiosomal setae, location of pores on idiosoma and ornamentation of dorsal shields like in females. Interval between setae J 6 and J 6 is 49–54. The interval between setae Z 5 and J 6 is 20–26.

Deutonymph ( Fig. 5). Length of idiosoma in 6 paratypes 268–290, width 189–200.

Podonotal setae j 1, r 1, r 4, r 6 and r 7 markedly elongated, densely plumose, brush-like and apically rounded. Setae r 3 and r 5 pilose or plumose, other podonotal setae short, smooth and needle-like. Opisthonotal setae J 1 –J 5, Z 1 and setae in R series short, smooth and needle-like, setae S 1, Z 2, Z 3 and Z 5 plumose and other opisthonotal setae similar to r 1. The interval between setae J 6 and J 6 is 57–63. The interval between setae Z 5 and J 6 is 20–21.

Protonymph ( Fig. 6). Length of idiosoma in 3 paratypes 208–253, width 137–161.

Podonotal setae j 1, j 3, r 3, r 4, r 6 and r 7 markedly elongated, densely plumose, brush-like and apically rounded. Other podonotal setae short, smooth and needle-like. Opisthonotal setae J 1 –J 5, Z 1, Z 2, Z 5 and S 1 short, smooth and needle-like, other opisthonotal setae similar to r 3. The interval between setae J 6 and J 6 is 45–57. The interval between setae Z 5 and J 6 is 10–12.

Etymology. The name of the new species is dedicated to MiraÇ (son of the second author).

Remarks. Mean lengths and ranges of setae on opisthonotum are given in Table 1 for female, male, deutonymph and protonymph specimens. Prozercon miraci sp. nov. is quite similar to P. buraki Urhan 2008 and P. sellnicki Halašková, 1963 . The distinctive morphological features of these three species are shown in Table 2.
