Holotype f. “ Turkey , Artvin , Yusufeli, Bahceli village, 1350 m , 20 September, 1992, collected by R. Urhan.” Sample from moss pads underlying soil in a coniferous forest (mostly Pinus sp. and Picea orientalis ). Paratypes : 30 ff, 6 mm ; from the same sample; other paratypes from: Turkey , Artvin , Yusufeli, Cevreli village, 1550 m , 17 August, 1993, collected by R. URHAN . Sample from litter and soil underlying Pinus sp. in a mixed forest: 5 ff, 4 mm . Type deposition; holotype and 8 paratypes (5 ff, 3 mm ) at the Zoological Museum of Atatürk University, Erzurum , Turkey . Other paratypes (30 ff, 7 mm ) are deposited in the authors’ collection Female ( Figs 2 A, B ). Length of idiosoma (excluding gnathosoma) of holotype 520 µm, width 392 µm.Measurement of 35 paratypes ; mean length 520 (507–538) µm, mean width 380 (357–398) µm. Dorsal setae ( Fig. 2A ). On the podonotum seta j1 feathered the remainder short and smooth. On the opisthonotum setae J 1 and Z 1 short and smooth. Setae J 2 –J 6 long, barbed with hyaline ending. Seta J 2 does not reach the base of seta J 3 . Seta J 3 reaching to the base of seta J 4 . Seta J 5 exceeding posterior margin of opisthonotum. Seta J 6 110 µm (on average) apart from each other. Setae Z 2 –Z 4 long, barbed with hyaline ending. Seta Z 3 reaching to the base of seta Z 4 . Seta Z 4 exceeding posterior margin of opisthonotum. Seta Z 5 long and smooth. The distance between setae Z 5 –J 6 26 µm. Setae S 1 –S 4 similar to seta J 6 . Seta S 2 exceeding margin of opisthonotum. All marginal setae of opisthonotum short and smooth. Lengths and their mutual distances of opisthonotal setae are given in Table 4. Pores. Pore po 1 located on the line connecting setae s 1 –s 2 . Pore po 2 on the line connecting setae j 4 -s 4 . Pore po 3 posterior to the line connecting setae z 1 –s 5 . Pore Po 1 located anterior to the insertion of seta Z 1 . Pore Po 2 posterior to the line connecting setae Z 2 –S 2 . Pore Po 3 on the line connecting setae Z 4 –J 4 . Pore Po 4 on the line connecting setae S 4 –Z 5 . Sculpturing pattern. The ornamentation of the dorsal shields shown in Fig. 2A . Dorsal cavities distinct, well sclerotized, equal in size with axes parallel to the body axis. Venter ( Fig. 2B ). The chaetotaxy and shape of peritremal shield typical for the genus. Adgenital shields present with three pores. With four setae on the anterior margin of ventro-anal shield. Male ( Figs 2C, D ). Idiosoma (excluding gnathosoma) in 10 specimens ; mean length 405 (388–435) µm, mean width 283 (267–289) µm. Setae, poresand sculpture pattern on the podo- and opisthonotum as in female. The distance between setae J 6 –J 6 and Z 5 –J 6 avarage 92 µm and 20 µm, respectively. Lengths and their mutual distances of opisthonotal setae are given in Table 5. Distribution. Artvin , Turkey . Etymology. The specific ephithet refers to the delicate structure and setae of the idiosoma. Fig. 2. Zercon delicatus sp. n. : female: (A) dorsal idiosoma; (B) ventral idiosoma; male: (C) dorsal idiosoma; (D) ventral idiosoma Diagnosis. The new species Zercon delicatus sp. n. is closely related to Z. kaszabi BŁASZAK , 1978 and Z. embersoni BŁASZAK , 1985 ( BŁASZAK 1978 , 1985 ). The distinguishing characters among three the related species of the genus Zercon are given in Table 6.
