Abacoproeces topcui View in CoL sp. nov. ( Figures 1A–1D View Figure 1 and 2A and 2B View Figure 2 )

Type materials: Holotype 1 male, 2 male paratypes ( NUAM), TURKEY: Mersin, Abanoz plateau, (36°19′N, 32°57′E), 1361 m, 16.V.2008, leg. T. Türkeş. GoogleMaps

Description: Measurements of holotype. Total length 2.00; carapace: 0.75 long, 0.70 wide; chelicerae: 0.20 long; sternum: 0.50 long, 0.50 wide; abdomen 1.25 long, 1.20 wide; leg measurements are given in the Table.

Carapace yellow, with a cephalic lobe with deep groove and lateral depressions ( Figure 1A and 1C View Figure 1 ). Both rows of eyes more procurved. The median eyes are much more separated from each other than the lateral eyes. Chelicerae with 3 teeth, of which 2 are very large, third tooth small ( Figure 1D View Figure 1 ). Sternum yellowish brown with margin darker. Legs pale yellow. Abdomen oval, brown with dense hairs, habitus as in Figure 1A View Figure 1 .

Palpus: Cymbium boat-shaped, paracymbium 3-dimensional, nearly U-shaped and slender; angular at proximal end and more annular at distal end, embolus tapered, bent at end, and covered with wide membranous structure (membranous protectors), embolus shape nearly semicircular and embolus length between half and full length of cymbium, tibial apophysis consisting of 3 sections ( Figures 2A and 2B View Figure 2 ), trichobothria on tibiae I–IV, 3–3.

Female: Unknown.

Etymology: The species is named in honor of the Turkish arachnologist Prof Dr Aydın Topçu.

Natural history and distribution: Abacoproeces topcui sp. nov. inhabits the soil covering of a coniferous forest. Known from the type locality only.

Diagnosis: Abacoproeces topcui sp. nov. is very closely related to A. saltuum (L. Koch, 1872) from the Palearctic (cf. Wiehle, 1960: Figures 172–175; Heimer and Nentwig, 1991: Figure 361.1). Male differs from A. saltuum in shapes of the paracymbium, tibial apophysis, embolus, and cheliceral teeth ( Figure 2A and 2B View Figure 2 ).
