Etymology. The specific name is a noun in apposition, in honour of Prof. Dr. Vasiliki Kati ( Greece) , who has contributed substantially to the study of the fauna and the conservation of the Dadia National Park.

Diagnosis. Dysdera kati sp. n. in general appearance is very similar to D. longirostris by the extremely elongated chelicerae. The male is characterized by a medially curved finger-like lateral sheet apophysis on the distal division of the bulbus, similar to that in D. longirostris , but differ from the latter by having a hook-like crest at the apical part of the distal division ( Figs 7–9 , 15 ). The female has vulva with a configuration resembling that in D. longirostris , but differ from the later by the rectangular shape of the spermathecae ( Figs 12–13 , 16–17 ).

Description. Male (holotype). Total length 7.05; carapace 3.32 long, 2.33 wide. Cephalic region 1.78 wide. Abdomen 3.73 long, 1.85 wide. Eye sizes and interdistances: AME 0 17, PME 0.12, PLE 0.15, AME-AME 0.16, AME-PLE 0.01, PME-PME 0.01, PME-PLE 0.05. Distance between AME almost the same size as their diameter. Clypeus 0.12 long. Chelicerae 2.31 long, 0.65 wide at its base; fang long-sized, 2.18 long. Chelicera inner groove large-sized, more than ½ of cheliceral length; armed with three teeth (concentrated very near the base) and lamina at base; M>D=B; B close to basal lamina, M close to B almost touching it, D slightly below the center of the proximal half of chelicera which is covered with a row of bristles (distal half naked), distance between D and M about 2 times size of M. Labium 0.70 long, 0.66 wide at its base. Sternum 2.02 long, 1.15 wide, wrinkled. Carapace, maxillae, labium and sternum dark-brown. Legs orange. Abdomen whitish grey; book lung, opercula and margins of spiracles brown, sclerotized ( Figs 5–6 ). Leg measurements and leg spination are given in Tables 2 and 3. Palp as in Figs 7–9 , 14–15 . Femur 1.31 long. Bulb 1.07 long. Tegulum smaller than distal division of the bulbus in ventral view. Distal division ventrally with medially curved beak-like lateral sheet apophysis, apical part with hook-like crest.

Female (paratype). Total length 7.86; carapace 3.39 long, 2.58 wide. Cephalic region 1.94 wide. Abdomen 4.47 long, 2.39 wide. Eye sizes and interdistances: AME 0.19, PME 0.15, PLE 0.17, AME-AME 0.19, AME-PLE 0.02, PME-PME 0.02, PME-PLE 0.05. Distance between AME the same size as their diameter. Clypeus 0.15 long. Chelicerae 2.04 long, 0.82 wide at its base; fang long-sized, 2.10 long. Labium 0.74 long, 0.74 wide at its base. Sternum 2.11 long, 1.72 wide, darkened on borders. Carapace, leg and abdominal coloration as for male ( Figs 10– 11 ). Leg measurements and leg spination are given in Tables 4 and 5 . Palp femur 1.40 long. Vulva as in Figs 12–13 , 16–17 . Spermathecae rectangular, bacilli-form, as wide as dorsal arch base, overlapping with the distal part of the arch. Dorsal arch triangular, wider than long.

Distribution. Known only from the type locality in NE-Greece ( Fig. 1 ).

Chorotype: Probably Greek endemic.
