Figs 1–9 View FIGURES 1–6 View FIGURES 7–12 , 13–15 View FIGURES 13–15
Type material. Male holotype, Bulgaria, Eastern Rhodope Mountains, near the town of Madzharovo ( GPS coordinates: 41.65, 25.84), 04.05.2021, leg. Dragomir Dimitrov ( SMF) .
Etymology. Named after the Rhodope Mountains ( Bulgaria), where the holotype was collected.
Diagnosis. The male is morphologically similar to those of Brachythele langourovi Lazarov, 2005 and Brachythele bentzieni Zonstein 2007 , in the presence of an embolic keel ( Figs 7–8 View FIGURES 7–12 ). It can be distinguished by (1) the shape of the keel being more massive than in the other 2 species, and (2) the shape of the embolic portion—stout, curved ( Figs 7–9 View FIGURES 7–12 , 13–15 View FIGURES 13–15 ), whereas, in B. langourovi , it is curved but thinner ( Figs 10–12 View FIGURES 7–12 ) and, in B. bentzieni , it is straight ( Figs 26–27 View FIGURES 26–27 ).
Description. (Holotype male). Measurements: Total length 12.76; carapace length 6.30, width 4.70; sternum length 3.07, width 2.25; labium length 0.64; maxilla length 2.02; abdomen length 6.46, width 3.25; PMS length 0.62; PLS length 2.10. Palp. Femur length 2.31, patella length 1.16, tibia length 1.85, cymbium length 0.86, bulbus length 1.21. Leg measurements: I—15.45 (3.90, 2.84, 2.79, 3.35, 2.57), II—14.18 (4.09,7 2.52, 2.70, 2.89, 1.98), III—14.99 (3.94, 2.30, 2.54, 3.56, 2.65), IV—18.73 (4.16, 2.91, 4.22, 4.74, 2.70). Eyes’ diameters: ALE 0.22, AME 0.18, PLE 0.18, PME 0.175. Eyes’ interdistances: AME–AME 0.15, AME–ALE 0.11, ALE–PLE 0.10, PME–PME 0.39, PME–PLE 0.10.
Color ( Fig. 1 View FIGURES 1–6 ). Carapace brown, with darker margins ( Figs 1–2 View FIGURES 1–6 ). Legs more or less the same color as carapace. Sternum and coxae yellow-brown, coxae lighter ventrally. Sternal sigilla small and rounded, the posterior pair well visible, the other 2 much lighter ( Fig 3 View FIGURES 1–6 ). Chelicerae dark brown. Abdomen beige with darker brownish pattern ( Fig 1 View FIGURES 1–6 ). Spinnerets light beige ( Fig 4 View FIGURES 1–6 ).
Eyes. Eye region darker than surrounding dorsal surface of carapace, elevated. Eyes compact. Anterior eye row procurved, posterior one almost straight (as seen from dorsal side, Figs 1–2 View FIGURES 1–6 ).
Other somatic characters. Carapace dorsally covered with fine setae. Fovea visible, deep, recurved. Chelicerae with 8 promarginal teeth, dorsally covered with long, weak, dense setae. Maxillae with many small prolateral cuspules on basal part ( Fig 3 View FIGURES 1–6 ). Tibia I with distal spur bearing 2 strong spines ( Figs 5–6 View FIGURES 1–6 ). Scopula: distal on metatarsi, and entire on tarsi I–II; apical on tarsi III–IV. Trichobothria in 2 rows of 7–10 on tibiae and 9–11 on metatarsi. Paired claws with 7 teeth. PMS medium-sized; apical segment of PLS triangular.
Palp ( Figs 7–9 View FIGURES 7–12 , 13–15 View FIGURES 13–15 ). Femur, patella, and cymbium spineless. Tibia with 2 long dorsal spines. Bulbus pearshaped; apical part protruding, massive in 2/3 of its length; embolic portion narrow, twisted, with a small tubercle distally.
Female. Unknown.
Distribution. The species is known only from the type locality in the Eastern Rhodope Mountains, Bulgaria.
