Lebertia (s. str.) maglioi Thor, 1907

Material examined: Erzurum Province, Tortum, Çıpak stream, 40°14.10′N, 41°29.57′E, 1950 m a.s.l., 13.09.2006, (2/3) ; Ilıca, Toprakkale , 40°11.46′N, 40°56.51′E, 2150 m a.s.l., 14.09.2006 , (9/8).

Description. Male: Integument smooth, idiosoma L/W 900/696, Cx-I/II mL 176/158 (ratio 1.1), Cx-II posterior W 31, coxal field L/W 658/607, genital flap L 165, genital field W 150, capitulum vL 217, chelicera L 285, Ac-1–3 L 50– 48–33. Palp ( Figure 1A ) total L 388, P-1 32; P-2 97; P-3 94; P-4 126; P-5 39; P-2 ventral margin slightly concave, P-3 enlarged distally, P-4 with maximum H in basal part, peg-like seta small, ventral setae insertion 1:1:2. IV-L-1 with 1 dorsal seta and 2 dorsodistal setae, IV-L-5 with 2 long swimming setae ( Figure 1B ), IV-L-6 with 2 ventral setae, IV-L-5 L/H 283/47, ratio 6.0, IV-L-6 L/H 261/50, ratio 5.2.

Female: (n = 3) Idiosoma L/W 770–1040/594–776, Cx-I/II mL 158–175/140–165 (ratio 1.0–1.1), Cx-II posterior W 28–40, coxal field L/W 632–700/537–642, genital flap L 176–192, genital field W 144–173, capitulum vL 215, chelicera L 269, Ac-1–3 L (56–60)–(50–55)– (39–41); palp total L 328–374, P-1 26–30; P-2 82–94; P-3 83–97; P-4 106–115; P-5 31–38. IV-L-1 with 1 dorsal seta and 2 dorsodistal setae, IV-L-5 with 2 long swimming setae ( Figure 1C ), IV-L-6 with 2 ventral setae, IV-L-5 L/H 252–260/47–48, ratio 5.4, IV-L-6 L/H 240–248/49–50, ratio 4.9–5.0.

Remarks: Specimens from Turkey are in good agreement with European Lebertia maglioi in the combination of a smooth, finely porose integument, the medial sutures of Cx-I/II similar in length, low number of swimming setae, and reduced number of ventral setae on IV-L-6. They differ in the length of the 2 swimming setae of IV-L-5, which is more than half of the next segment (in particular in the juvenile specimens, the 2 swimming setae on IV-L-5 are very long; see Figure 1C ), the greater distance of dorso- and mediodistal setae on P-3, and the distally narrower P-4. Turkish specimens here attributed to L. maglioi are similar to L. alia Semenchenko and Tuzovskij, 2010 (with one swimming seta on IV-L-5 longer than onehalf IV-L-6). L. alia differs from Turkish specimens in the very slender P-3 with dorso- and mediodistal setae closer to each other ( Semenchenko and Tuzovskij, 2010). However, more extensive variability studies could demonstrate the synonymy of L. alia with L. maglioi .

Previous record from Turkey: Niğde Province ( Gerecke, 2009).

Distribution: West Palearctic ( Gerecke, 2009).

Lebertia (s. str.) marasensis sp. nov.

Type series: Holotype, male, Kahramanmaraş Province, from a limnocrene spring near Lake Kumaşır , 37°22.22′N, 37°22.58′E, 460 m a.s.l., 12.09.2012 . Paratypes: Same locality as holotype (4/7).

Further record: Kahramanmaraş Province, Çağlayancerit, Lake Değirmen , 37°43.18′N, 37°29.10′E, 880 m a.s.l., 11.09.2012 (3/4).

Diagnosis: Integument smooth, laterally with fine striation, idiosoma slightly elongated; Cx-I/II mL ratio 0.8–0.9, posterior margin Cx-II wide, medial and lateral margins of Cx-IV forming an acute angle; IV-L-1 with 1 dorsal seta and 2 dorsodistal setae, IV-L-6 with 4–6 ventral setae, number of swimming setae III-L-5, 2; IV-L-5, 3 (one of them very characteristically distanced from distal edge); P-3 equally enlarged from base to distal margin, dorsal setae distanced away from each other, medio- and dorsodistal setae close to each other, ventrodistal setae close to distal margin, P-4 with maximum H in distal part, ventral setae insertions equidistant (1:1:1), peg-like seta slender.

Description. Male: Idiosoma ( Figure 2A) L/W 1025/746, Cx-I/II mL 174/200 (ratio 0.87), Cx-II posterior W 48, coxal field L/W 720/583, genital flap L 184, genital field W 149, capitulum vL 214, chelicera L 308, Ac-1–3 L 63–52–37.

C A B

Female: Idiosoma L/W 1070/800, Cx-I/II mL 180/197 (ratio 0.9), Cx-II posterior W 44, coxal field L/W 725/590, genital flap L 200, genital field W 154, capitulum vL 244, chelicera L 318, Ac-1–3 L 72–61–40. Palp total L 400, P-1 40; P-2 108; P-3 100; P-4 118; P-5 34. IV-L-5 L/H 298/47, ratio 6.3, IV-L-6 L/H 273/50, ratio 5.5.

Etymology: Named after the province of Kahramanmaraş in which the species was found.

Habitat: The specimens of Lebertia (s. str.) marasensis were collected from a limnocrene spring.

Remarks: Due to the relatively long mL Cx-II, ventrodistal setae on P-3 close to distal edge, and 3 long swimming setae on IV-L-5 (one of them characteristically distanced from distal edge), Turkish specimens are different from L. cognata . While the position of the ventrodistal seta on P-3 has been found to be variable in L. cognata specimens from Central Europe ( Gerecke, 2009), the latter differ also in the higher number of ventral setae on IV-L-6 (about 6–8) and Cx-I longer than Cx-II. Furthermore, the new species is similar to L. fimbriata in integument structure, shape, and setal arrangement on the palp, and number of swimming setae on IV-L-5. It differs from the latter in elongated palp segments and a higher number (4–6) of ventral setae on IV- L-6 (in L. fimbriata IV-L-6 with 2–3 ventral setae).

Distribution: Turkey, only known from type locality.

ESEN and ERMAN / Turk J Zool posterior W 42–48, coxal field L/W 720/541, genital flap L 160–178, genital field W 142–151, capitulum vL 160–200, chelicera L 222–260, Ac-1–3 L (60–70)–(56–68)–(35–41).

Remarks: As compared with the diagnosis established for Central European L. fimbriata , specimens from Kahramanmaraş Province differ as follows: specimens from Fındıklı, Fırnız, and Ardıç streams have 2 swimming setae on IV-L-5, a short swimming seta on IV-L-4, and ventral setae insertions on P-4 distanced 1:1:1. Specimens from Sevdili and Söğütlü streams have 3 long swimming setae on IV-L-5, 1 long swimming seta on IV-L-4, and ventral setae insertions on P-4 distanced 3:3:2. We interpret these differences as examples of geographical variability in L. fimbriata .

Female: Idiosoma ( Figure 8B ) L/W 864–960/698–762, Cx-I/II mL 194/98 (ratio 2.0), Cx-II posterior W 50, coxal field L/W 611/523, genital flap L 195, genital field W 183 ( Figure 8C ), capitulum vL 239, chelicera L 264, Ac-1–3 L 47–46–38. Palp total L 238, P-1 32; P-2 58; P-3 53; P-4 70; P-5 25.

Remarks: Lebertia (Brentalebertia) minutipalpis is characterized by the combination of the following features: Cx-I with distinct downwardly curved tips; Cx-II very short and posteriorly wide; Ac-1–3 rather short and placed on elevated and strongly sclerotized acetabular bases, at least some of them slightly constricted in the center; palp
