Zercon thracicus sp. nov. Z. carpathicus Sellnick, 1958 Z. inonuensis Urhan, 2007 Remarks. Average lengths of opisthonotal setae and distances between setae within longitudinal rows of females, males, deutonymphs and protonymphs specimens: see Table 13. Zercon thracicus sp. nov. is closely related to Z. carpathicus Sellnick and Z. inonuensis Urhan. The distinguishing characters of these three related species are shown in Table 14. This species was the third abundant specimens of genus Zercon in the study area.
Etymology. The specific name thracicus reflects the Thrace region of Turkey where the new species were collected.
