Diagnosis. Easily distinguished from known congeners by subdistal process on embolar sclerite (arrows in Figs 153 View FIGURES 152–157 , 162 View FIGURES 158–167 ); also by combination of: procursus ( Figs 158–159 View FIGURES 158–167 ) ventral ‘knee’ very indistinct, ventral spine of procursus not strongly curved at half length (in contrast to H. dim   ), tip of procursus with pointed prolateral process (arrow in Fig. 158 View FIGURES 158–167 ) and prolateral ridge (very similar to H. dim   ); ventral sclerite of genital bulb ( Figs 162–165 View FIGURES 158–167 ) slender, embolar sclerite with small cone-shaped processes. Females are difficult to distinguish externally from congeners, especially from H. dim   (females of these two species possibly not distinguishable); posterior light median area of epigynal plate usually clearly separated from rest of dark plate; sclerotized external margins of lateral pouches of uterus externus usually visible in uncleared specimens ( Figs 155 View FIGURES 152–157 , 166 View FIGURES 158–167 ).

Etymology. The species name is derived from the type locality; noun in apposition.

Description. Male (holotype). MEASUREMENTS. Total length 4.0, carapace width 1.8. Distance PME-PME 120 µm; diameter PME 120 µm; distance PME-ALE 40 µm; diameter AME 70 µm; distance AME-AME 60 µm. Leg 1: 34.1 (9.2 + 0.8 + 9.7 + 12.3 + 2.1), tibia 2: 6.5, tibia 3: 4.7, tibia 4: 5.9; tibia 1 L/d: 61.

COLOR (in ethanol). Carapace ochre-yellow, ocular area and posterior median triangle light brown, clypeus barely darker; sternum dark brown; legs ochre-yellow to light brown, with darker rings subdistally on femora and tibiae and in patella area; abdomen gray, with pairs of large black marks dorsally, oblique marks in posterior third; ventrally with large light brown mark anteriorly, black mark at spinnerets and smaller diffuse brown mark in-between.

BODY. Habitus as in Fig. 121 View FIGURES 118–123 . Ocular area slightly elevated. Deep thoracic pit and pair of furrows diverging from pit toward posterior margin. Clypeus unmodified. Sternum wider than long (1.2/0.8), unmodified. Abdomen oval, dorso-posteriorly rounded.

CHELICERAE. As in Figs 160–161 View FIGURES 158–167 , with pair of latero-distal apophyses provided with one and two modified cone-shaped hairs respectively (the illustrated chelicerae are not from the holotype); stridulatory ridges fine, barely visible in dissecting microscope.

PALPS. As in Figs 152–154 View FIGURES 152–157 ; coxa with very low retrolateral bulge, trochanter barely protruding ventrally, femur with distinct dark line retrolaterally, with prolateral stridulatory pick; procursus ( Figs 158–159 View FIGURES 158–167 ) with very indistinct ventral ‘knee’, ventral spine weakly indented at half length, tip curved toward dorsally, slender pointed prolateral process, prolateral ridge with small pointed process; genital bulb ( Figs 162–165 View FIGURES 158–167 ) with distinctive process subdistally on embolar sclerite (arrows in Figs 162, 164 View FIGURES 158–167 ), embolar sclerite with several additional small cone-shaped processes, ventral sclerite slender.

LEGS. Femur 1 with single row of ~22 ventral spines; without curved hairs; few vertical hairs; retrolateral trichobothrium of tibia 1 at 5%; prolateral trichobothrium present on all leg tibiae; tarsi without distinct pseudosegments but with many small platelets.

Male (variation). Tibia 1 in two other males from type locality: 9.0, 9.1. Modified hairs on cheliceral apophyses in other males symmetric (2+2). Number of spines on femur 1 slightly variable. The males from Bursa Province and from Greece are apparently identical to the holotype in all relevant aspects; tibia 1 in male from Bursa Province: 9.2; in males from Greece: 8.1, 10.3, 10.3, 10.9.

Female. In general similar to male but without spines on legs; several females with curved hairs on metatarsus 1. Tibia 1 in seven females from type locality: 8.0–10.2 (mean 9.2).

FEMALE GENITALIA. Epigynum as in Fig. 155 View FIGURES 152–157 , light median area of epigynal plate usually clearly separated from rest of dark plate, pair of internal lateral pouches and sclerotized arcs visible in uncleared specimens; with pair of light brown weakly bulging areas in front of epigynum; posterior plate simple, short but wide. Internal genitalia with large medially narrowing pore plates ( Figs 157 View FIGURES 152–157 , 167 View FIGURES 158–167 ), pair of lateral pouches of uterus externus with sclerotized external margins ( Figs 156 View FIGURES 152–157 , 166 View FIGURES 158–167 ), median pouch of uterus externus shallow and membranous, only visible in lateral view of cleared specimen. Females from Bursa Province and from Greece in general very similar to females from type locality, including pair of lateral pouches of uterus externus with sclerotized external margins ( Figs 174–175, 177–178 View FIGURES 174–185 ); however, pore plates much larger in female from Bursa Province and intermediate in single cleared female from Greece ( Figs 176, 179 View FIGURES 174–185 ).

Distribution. Apparently widespread in Turkey and Greece ( Fig. 440 View FIGURE 440 ).

Natural history. In Yalan Dünya Cave the spiders occupied a limited area in the twilight zone and did neither occur in the entrance area nor in deeper parts. Most specimens were found hanging in their domed sheet webs close to the ground.
