Figs 21–34

Type material. Holotype: male ( NHMC, FC 17165), Dadia , under stone near info center of the Dadia National Park, 92 m a.s.l., 0 4.04.2015, leg. M. Komnenov. Paratypes: 1 ♀ ( NHMC, used for description), same data as holotype. Other material examined: Site 1 (f: 1 ♀, Site 3 (e: 1 ♀), Site 4 (a: 2 ♀), Site 7 (a: 1 ♀), Site 9 (a: 1 ♂).

Comparative material examined. 2 ♂, 2 ♀, Dysdera dunini Deeleman-Reinhold, 1988 , UKRAINE, Crimea, Feodosiya District, Karadag Nature Reserve, North Pass, Quercus petraea forest, pitfall traps, 07- 21.06.2008, leg. A.A. Nadolny ( Figs 35–36 ).

Etymology. Named after financial crisis (“ krisis ” in Greek) situation in Greece, coinciding with the period of this species description, applied here as a noun in apposition.

Diagnosis. This species resembles Dysdera dunini Deeleman-Reinhold, 1988 but can be distinguished by the bifurcated, scissors-like apical part of distal division of males ( Fig. 25–26 , 29–32 ) and by the slightly larger spermathecae in relation to the dorsal arch of females.

Description. Male (holotype). Total length 6.42; carapace 2.75 long, 2.06 wide, punctuated. Cephalic region 1.50 wide. Abdomen 3.57 long, 1.81wide. Eye sizes and interdistances: AME 0.16, PME 0.12, PLE 0.16, AME- AME 0.11, AME-PLE 0.01, PME-PME 0.01, PME-PLE 0.04. Distance between AME greater than their diameter. Clypeus 0.11 long. Chelicerae 2.09 long, 0.66 wide at its base; fang long-sized, 2.07 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>B>D; B close to basal lamina, M close to B, distance between them as the size of M, D slightly above the center of the proximal half of cheliceral length which is covered with a row of bristles (distal half naked), distance between D and M about 3 times size of M. Labium 0.60 long, 0.55 wide at its base. Sternum 1.75 long, 1.32 wide, darkened on borders. Carapace, maxillae, labium and sternum orange-brown. Legs orange. Abdomen whitish grey, freckled, with lighter cardiac mark ( Figs 21, 23 ). Leg measurements and leg spination are given in Table 6 and Table 7 . Palp as in Figs 25–26 , 29–32 . Femur 1.17 long, smaller than Cx I. Bulb 1.03 long. Tegulum smaller than distal division of the bulbus in ventral view. Distal division with three axes forming almost the same angles. Posterior apophysis thumb-like, white-colored, with rough surface at its end. Apical part darker, rather penguin feet shaped in apical view.

Female (paratype). Total length 9.34; carapace 3.91 long, 2.97 wide. Cephalic region 2.28 wide. Abdomen 5.34 long, 2.58 wide. Eye sizes and interdistances: AME 0.22, PME 0.16, PLE 0.21, AME-AME 0.21, AME-PLE 0.02, PME-PME 0.02, PME-PLE 0.06. Distance between AME the same size as their diameter. Clypeus 0.16 long. Chelicerae 2.40 long, 0.90 wide at its base; fang long-sized, 2.49 long. Labium 0.90 long, 0.85 wide at its base. Sternum 2.39 long, 1.83 wide, darkened on borders. Carapace, leg and abdominal coloration as for male ( Figs 22, 24 ). Leg measurements and leg spination are given in Table 8 and Table 9 . Palp femur 1.59 long, smaller than Cx I. Vulva as in Figs 27–28 , 33–34 . Spermathecae trapezoid, narrower than dorsal arch base, overlapping with the greater part of the distal half of the arch. Dorsal arch trapezoid, approximately as wide as long.

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

Chorotype. Probably Greek endemic.
