Type material. Holotype: male ( NHMC, FC 12112), Dadia National Park, maqui, Site 1, 05.05– 05.06.2009, leg. Karakatsanis. Paratypes: 1 ♂ ( NHMC, FC 12147, used for description), Dadia National Park, humid grassland, Site 13, 24.05– 02.07.2011, leg. K. Zografou. Other material examined: Site 3 (e: 1 ♂), Site 13 (a: 1♀), Site 15 (a: 1 ♀).

Etymology. The specific name is a noun in apposition taken from the type locality.

Diagnosis. Drassyllus dadia sp. n. seems closest to Drassyllus villicus (Thorell, 1875) but can be separated by shorter terminal apophysis ( Figs 115 , 120 ) and the dorsal projection of the retrolateral tibial apophysis of males ( Figs 114 , 119 ), and by the almost straight introductory orifices and anterior epigynal margin of females ( Figs 117 , 121 ).

Description. Male (holotype). Total length 4.37; carapace 2.0 long, 1.58 wide. Abdomen (detached from the body) 2.37 long, 1.42 wide. Eye sizes and interdistances: AME 0.06, ALE 0.11, PME 0.10, PLE 0.08, AME-AME 0.07, AME-ALE 0.02, ALE-PLE 0.05, PME-PME 0.03, PME-PLE 0.05; MOQ: 0.24 long, 0.17 anterior width, 0.23 posterior width. Clypeus under AME 0.12 high, under ALE 0.10 high. Chelicerae black brown, promarginal and retromarginal teeth not visible. Maxillae, labium and sternum dark brown in contrast to black brown carapace. Maxillae and labium longer than wide. Sternum heart-shaped, with dense dark hairs at the edges. Legs orange, except femur that is black brown. Leg spination: femora: II d 1-1-0; III d 1-1-0; IV d 1-1-0; patella: III r 1; tibiae: I v 1-1 -0; II v 1-1 -0; III v 2-2 -2, r 1-1, p 1-1, d 0-2-0; IV v 2-2 -2, r 1-1, p 1-1, d 0-2-0; metatarsi: I v 2 -0-2; II v 2 -0- 2; III d 0-1-2, r 1-1, p 1-1, v 2 -0; IV v 2-2 -2, d 2-2-2, r 1-0, p 1-1. Abdomen black brown, dorsally with shiny scutum covering ⅓ of the abdomen. Palp as in Figs 114–116 , 119–120 . Retrolateral tibial apophysis with stiff setae dorsally and dorsal projection shifted anteriorly; terminal apophysis short, rectangular, approximately as wide as high, with distal edge almost straight, terminal apophysis base retrolaterally projecting, needle-shaped, almost reaching the tip of median apophysis and the retrolateral edge of the cymbium; origin of embolus slightly abrupt; embolus relatively short, proximal half of the embolus almost straight, distal half slightly curved.

Female (paratype). Total length 4.43; carapace 1.77 long, 1.43 wide. Abdomen 2.66 long, 1.52 wide. Eye sizes and interdistances: AME 0.05, ALE 0.1, PME 0.1, PLE 0.08, AME-AME 0.05, AME-ALE 0.01, ALE-PLE 0.06, PME-PME 0.01, PME-PLE 0.04; MOQ: 0.21 long, 0.16 anterior width, 0.20 posterior width. Clypeus under AME 0.08 high, under ALE 0.05 high. Eye arrangement, carapace, leg and abdominal coloration as for male. Leg spination. Leg I and II missing. Femora: III d 1-1-0; IV d 1-1-0; tibiae: III v 1-2 -2, r 1-1, p 1-1, d 0-2-0; IV v 0-2-0, r 1-1, p 1-1, d 2-2-2; metatarsi: III d 0-1-2, r 0-0, p 1-1, v 1-2; IV v 2-2 -0, d 2-2-2, r 1-0, p 1-1. Epigyne as in Figs 117 , 121 . Anterior margin almost straight, with small protrusion, reaching the height of introducrory orifices; introducrory orifices at anterior part of the epigyne, short, almost straight. Vulva as in Figs 118 , 122 . Introductory ducts semi-circular, almost touching each other in the middle, opening posteriorly to reach the spermathecae; small lateral glandular heads at upper half of introductory ducts; distance between spermathecae about half of their diameter.

Distribution. Known only from the type locality in NE-Greece ( Fig. 1 ). Chorotype: Probably Greek endemic.
