Lebertia (s.str.) erzurumensis Esen and Erman , sp. nov.
Type series
Holotype. Male, dissected and slide-mounted in Hoyer’s fluid, Erzurum Province, Hasankale , Tımar stream, 40 ◦ 02 ′ 33 ′′ N 41 ◦ 37 ′ 13 ′′ E, 1950 m asl, 12 September 2006.
Paratypes. One male and one female slide-mounted in glycerine jelly, same data as holotype.
Diagnosis
Integument smooth. Medial suture Cx-I longer than Cx-II (ratio 1.1–1.3). Leg swimming setae numbers: II-L-5, 1; III-L-5, 3; IV-L-5, 3 (in L slightly exceeding 1 / 2 L IV-L-6, rather fine). Palp total L in male 355, in females 398, P-3 mediodistal seta located halfway between ventro- and dorsodistal setae; P-4 maximum H in basal part of segment, distally distinctly narrowed, ventral sectors 1:3:3.
Description
Both sexes. Colour greenish. Posterior margin of Cx-II narrow; Cx-IV with rounded posterior margins, laterocaudally straight ( Figure 3A View Figure 3 ); IV-L-1 with one dorsal and two dorsodistal setae, IV-L-5 with five to six strong ventral setae, IV-L-6 with two to three hair-like ventral setae ( Figures 3C and D View Figure 3 ); palp: ( Figures 3B and 3E View Figure 3 ) P-2 ventral margin concave, P-3 with dorsal setae separated and mediodistal seta nearly in centre of distal margin.
Male (holotype). Idiosoma L / W 985 / 807, Cx-I / II mL 171 / 153, posterior margin Cx- II W 32; genital flap L 163, genital field W 145; Ac-1-3 L 52 / 48 / 36; gnathosoma L 230, chelicera L 247, L / H ratio 5.3, basal segment / claw ratio 5.2; palp ( Figure 3B View Figure 3 ): L / H, L / H ratio, relative L P-1, 29 / 46, 0.6, 8.2%; P-2, 90 / 64, 1.4, 25.3%; P-3, 94 / 50, 1.9, 26.5%; P-4, 111 / 41, 2.7, 31.3%; P-5, 31 / 17, 1.8, 8.7%; total L 355; L / H IV-L-4, 247 / 53; IV-L-5, 269 / 47; IV-L-6 248 / 46.
Female. Idiosoma L / W 990 / 790, Cx-I / II mL 189 / 143, posterior margin Cx-II W 35; genital flap L 190; genital field W 169; Ac-1-3 L 63 / 52 / 40; gnathosoma L 242, chelicera L 267, L / H ratio 5.3, basal segment / claw ratio 5.3; palp ( Figure 3E View Figure 3 ): L / H, L / H ratio, relative L P-1, 34 / 50, 0.7, 8.5%; P-2, 98 / 67, 1.5, 24.6%; P-3, 102 / 50, 2.0, 25.6%; P-4, 126 / 41, 3.1, 31.7%; P-5, 38 / 19, 2.0, 9.6%; total L 398; L / H IV-L-4, 265 / 56; IV-L-5, 287 / 50; IV-L-6 267 / 50.
Discussion
Lebertia erzurumensis sp. nov. is similar to L. rivulorum and L. pusilla in the elevated number of swimming setae on III / IV-L-5. It resembles L. rivulorum in the shape and setation of the palp, but L. rivulorum differs in having more (four to five) swimming setae on IV-L-5. Lebertia pusilla , a species with the same swimming seta pattern III / IV- L-5 as in the new species, differs in a shorter palp (total L male 240–280, female 260–320), the arrangement of the setae on P-3 (mediodistal seta closer to dorsodistal seta), and IV-L-5 bearing a lower number of three to four strong ventral setae and distinctly longer swimming setae.
