3.1. Prozercon giresunensis sp. nov.

( Figures 1A–1D )

Type material: Holotype ♀. Turkey, Giresun, Şebinkarahisar , mixed forest, 40°17′28.10″N, 38°28′19.85″E, 1215 m, 27 March 2011, collected by M. Öztaş. Samples from litter and soil under Pinus sylvestris . Paratypes: 10 ♀♀, 1 ♂; same data as holotype . Holotype and paratypes are deposited in the Department of Biology of Pamukkale University, Denizli, Turkey .

Diagnosis: Posterolateral tips of peritrematal shields reaching the bases of marginal setae R 5 or R 6. Margin of opisthonotum with 8 pairs of setae. Setae j1, r1, r4, and r7 markedly elongated, densely plumose, brush-like, and apically rounded; setae j2, z2, s5, r2, r3, r5, and r6 pilose or plumose; other podonotal setae short, smooth, and needle-like. Setae J 1 –J 5, Z 1 –Z 5, and S 1 plumose; setae J 6 and S 2 –S 4 densely plumose, brush-like, and apically rounded. Setae J 1 not reaching bases of setae J 2. Setae R 1 plumose, the remainder in this row short and smooth. Dorsal cavities distinct, sclerotized, equal in size and form.

Description: Female.

Dorsum ( Figure 1A ). Length of idiosoma in holotype 343 µm, width 241 µm. Measurement of 10 paratypes: length 335–350 µm, width 233–250 µm. Ornamentation of dorsal shields shown in Figure 1 . Dorsal cavities distinct, sclerotized, equal in size and form.

Setae ( Figure 1A ). On podonotum, 20 pairs of differently formed setae present: j-setal row with 6 pairs of setae, z-setal row with 2 pairs, s-setal row with 5 pairs, and r-setal row with 7 pairs. Podonotal setae j1, r1, r4, and r7 markedly elongated, densely plumose, brush-like, and apically rounded; setae j2, z2, s5, r2, r3, r5, and r6 pilose or plumose; other podonotal setae short, smooth, and needle-like. On opisthonotum, 23 pairs of setae present: J-setal row with 6 pairs of setae, Z-setal row with 5 pairs, S-setal row with 4 pairs, and R-setal row with 8 pairs. Opisthonotal setae J 1 –J 5, Z 1 –Z 5, and S 1 plumose; setae J 6 and S 2 –S 4 densely plumose, brush-like, and apically rounded. Setae J 1 with tips not reaching bases of setae J 2. Setae J 2 reaching bases of setae J 3 (as well as setae J 3 and J 4). Setae J 5 reaching posterior margin of opisthonotum. Insertions of setae J 6 –J 6 situated 61–68 µm apart. Setae Z 2 not reaching bases of setae Z 3. The distance between setae Z 5 and J 6 is 26–30 µm. Setae R 1 plumose, the remainder in this row short and smooth. Lengths of opisthonotal setae and distances between setae within longitudinal rows are depicted in Table 1.

Pores ( Figure 1A ). On the podonotum, pores po1 located at the medial bases of setae s1. Pores po2 lie on the line connecting setae s3–j4, closer to s3. Pores po3 on the lateral line connecting setae s4–s5. On the opisthonotum, pores Po1 located anteroparaxially to the bases of setae Z 1. Pores Po2 lie on line connecting setae S 1 –S 2, closer to S 1, or on the lateral line connecting setae S 1 –Z 2. Pores Po3 situated between setal rows Z and S, lateral line connecting setae Z 3 –Z 4, closer to Z 3. Pores Po4 lie on a line connecting setae S 4 –Z 4.

Venter ( Figure 1B ). Chaetotaxy and shape of the peritrematal shields typical for the genus. Adgenital shields and pores gv2 absent. Anterior margin of the ventrianal shield with 2 setae.

Allotype: Male ( Figures 1C and 1D ). Idiosoma length 286 µm, width 195 µm. Setae, pores, and sculpturing pattern of the podonotum and opisthonotum same as in female. Distance between setae J 6 and J 6 58 µm. Distance between setae Z 5 and J 6 23 µm. Lengths of opisthonotal setae and distances between setae within longitudinal rows shown in Table 1.

Remarks: Prozercon giresunensis sp. nov. is closely related to P. balikesirensis Urhan, 2008 ; P. dominiaki Błaszak, 1979 ; and P. dramaensis Ujvári, 2011 . The distinguishing characters of the 4 related species of the genus Prozercon are given in Table 2.

Etymology: This species is named after its type locality,

Giresun ( Turkey).
