Etymology: The specific epithet is a patronym honoring a Turkish entomologist, Dr. Bilgenur Baloğlu.
Diagnosis: The males of H. bilgenur sp. nov. resembles H. rubicunda (C. L. Koch, 1838), widely distributed across northern and eastern Europe, and H. doblikae (Thorell, 1875), whose distribution is limited to Eastern Europe (Bulgaria and Ukraine), by the general shape of bulb. H. bilgenur sp. nov. differs from the aforementioned species in that it has a larger, more spherical tegulum, and the embolus is longer and sickle-shaped, while in H. rubicunda and H. doblikae the embolus is shorter and hook-shaped (Figs 48–52). The vulva of H. bilgenur sp. nov. is also close to that of the aforementioned species. However, in H. bilgenur sp. nov. the distance between the region where the spermatheca expands and the tip is longer than in the other two species (Figs 53–54).

Small sized harpacteine spiders. Carapace light brown in both sexes. Thoracic region pentagonal; head region roundish anteriorly. Fovea dark brown, longitudinal (Fig. 46). AE, PLE and PME are close to each other, arranged annularly, silvery. AEs seperated; there is also some distance between PLE and PMEs. Eyes not in contact with each other. Sternum, labium, gnatocoxae yellowish. Chelicerae reddish. There are four small teeth in the cheliceral groove, two in the promarginals and two in the retromarginals. The promarginal teeth are about twice the size of the retromarginal teeth, with a distance between them of about one and a half times their basal length. The first retromarginal tooth is aligned with the centre of the promarginal teeth and is very slightly smaller than the second retromarginal tooth (Fig. 47). Abdomen whitish, gray, cylindrical. Its surface is covered with blackish setae. Legs yellowish brown.Anterior legs darker than posterior legs. Leg formula: VI, I, II, III. Leg spination and measurements given in tables 11 and 12.
Palp (Figs 48–52): Palpal tarsus is almost the same length as the tibia. Tegulum globular (Figs 48–51). Embolus sickle-shaped. The proximal part of the embolus is wide, gradually narrowing towards the tip, which is slightly tilted anteriorly (Fig. 48). Conductor present; in the form of a sclerotized concavity coupled to the embolar base and curved towards the embolus tip (Fig. 48). There is a chitinized dentition at the tip of the conductor, which is difficult to see with a stereomicroscope but is distinct in SEM (arrow in figs 50, 52).
Vulva(Figs53–54): Spermathecal keel long, blunt tip.Spermatheca enlarged at the basal third.Roundishstructures are slightly tubercular, almost linear.
The central part of the transversal bar circular button-shaped and strongly sclerotized. It projects laterally but not as long as roundishstructures and anterior margin of the anterior arc. Posterior diverticulum membranous and wider than anterior arc (Fig. 54).
