description: 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); 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); palp: (Figures 3B and 3E) 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): 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): 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.
Etymology
Named after the province of the type locality.
Distribution
Only known from the type locality.
Habitat
Rhithrobiont.
