Cauda tapering, without constriction, 1.47 × its width at base and 0.12 × BL, with 14 fine setae of two lengths (Fig. 4g). Differential diagnosis . There are the seven Palaearctic species currently placed in Uroleucon with 3:3:3 setae on the first tarsal segments: Uroleucon bielawskii , U. dubium Holman, 1975, U. kashmiricum (Verma, 1966), U. mongolicum , U. mulgedii , U. pilosellae (Börner, 1933), and U. telekiae (Holman, 1965) (Nevsky 1928; Szelegiewicz 1962, 1982; Holman 1965, 1975, 1991; Verma 1966). Apterous viviparous females of Uroleucon ( Uroleucon ) lebanonense differ from the same morphs of U. bielawskii, U. dubium and U. mulgedii because they are classified into different subgenera according to the taxonomic criteria used by the authors (Szelegiewicz 1962, 1982; Holman 1975; Blackman & Eastop 2020).Apterae of U. lebanonense differ from the same morphs of U. kashmiricum by ( 1 ) number of secondary rhinaria on ANT III: 45–59 secondary rhinaria in the new species, while 10–30 secondary rhinaria are present in U. kashmiricum , ( 2 ) number of setae on ABD TERG VIII: 4–7 in the new species, while only 2 in U. kashmiricum , ( 3 ) SIPH/cauda ratio: 1.58–1.93 in the new species, while 1.30–1.33 in U. kashmiricum, ( 4 ) presence/absence of antesiphuncular sclerites: fragmented or vestigial sclerites present in the new species, while they are absent in U. kashmiricum (Verma 1966; Blackman & Eastop 2020). From U. pilosellae , the apterous morphs of U. lebanonense may be distinguished by ( 1 ) number of secondary rhinaria on ANT III: 45–59 secondary rhinaria in the new species, while 15–28 secondary rhinaria in U. pilosellae, ( 2 ) fragmented or vestigial sclerites are present in the new species, while large and solid sclerites are present in U. pilosellae (Heie 1995; Blackman 2010; Blackman & Eastop 2020). Apterous viviparous females of U. lebanonense differ from the same morphs of U. telekiae by ( 1 ) number of secondary rhinaria on ANT III: 45–59 secondary rhinaria in the new species, while 6–25 secondary rhinaria in U. telekiae, ( 2 ) URS/HT II ratio: 1.17–1.33 in the new species, while 1.50–1.80 in U. telekiae, ( 3 ) SIPH/BL ratio: 0.20–0.28 in the new species, while 0.32–0.38 in U. telekiae, ( 4 ) number of setae on cauda: 12–18 in the new species, while 20–26 in U. telekiae (Holman 1965; Heie 1995; Blackman & Eastop 2020). Among all known Palaearctic species of the subgenus Uroleucon with 3:3:3 setae on HT I, the new species is most similar to U. mongolicum , with a similar number of setae on ABD TERG VIII (4–7 in the new species and 3–5 in U. mongolicum ). However, apterous viviparous females of U. lebanonense are characterized by several differences in contrast to U. mongolicum : • Mesosternal furca without stem (furca with robust stem in U. mongolicum ); • Cauda with 12–18 setae (Fig. 2g) (cauda with 7–11 setae in U. mongolicum , (Fig. 2h)); • SIPH tapering gradually from base to apex (Fig. 2e) (SIPH with subapical constriction and slightly flared apex (Fig. 2f)); • Lower ratio of SIPH/cauda—1.58–1.93 (1.80-2.60 in U. mongolicum respectively); • Secondary rhinaria with sclerotized rims (fig. 2a) (secondary rhinaria without sclerotized rims in U. mongolicum (Fig. 2b)); • Dorsum of abdomen smooth without reticulation (Fig. 3c) (dorsum of abdomen with well–developed reticulation in U. mongolicum (Fig. 3d)); • Higher ratio of URS/ANT III—0.24–0.26 and URS/ANT VI—0.23–0.25 (0.16–0.21 and 0.16–0.19 in U. mongolicum respectively). Alate viviparous females of the new species can be distinguished from the same morph of U. mongolicum by: • SIPH tapering gradually from base to apex (Fig. 4e) (SIPH with distinctly constricted reticulation area in U. mongolicum (Fig. 4f)); • Secondary rhinaria with sclerotized rims (Fig. 4a) (secondary rhinaria without sclerotized rims in U. mongolicum (Fig. 4b)); • Cauda elongate triangular without constriction near base, with 14 setae (Fig. 4g) (cauda finger–like constricted near base, with 7–11 setae in U. mongolicum (Fig. 4h); • Marginal sclerites on ABD TERG IV smaller than those on ABD TERG III (Figs 1c, 5a) (marginal sclerites on ABD TERG IV as big as or larger than those on ABD TERG III in U. mongolicum (Figs 1d, 5b)); • Higher ratio of ANT IV/ANT V—1.35–1.36, URS/ANT VI—0.23–0.24 and HT II/ANT III—0.19–0.20 (1.22– 1.25, 0.15–0.19 and 0.13–0.14 in U. mongolicum respectively). Etymology. Name of the new species is derived from Lebanon, where it has been collected. Biology and distribution. So far Uroleucon lebanonense is known only from its type locality in the vicinity of Jazzine in Lebanon. Other morphs and life cycle of the new species are unknown. Hille Ris Lambers put the name Tragopogon coloratus as the plant from which the new species has been collected. However T. coloratus is known to be native to Iran, Transcaucasus (including Armenia, Azerbaijan and Georgia) and Turkey (Kilian et al. 2009). In Lebanon there are records for T. buphthalmoides , T. coelesyriacus , T. porrifolius , and T. pterocarpus (Kilian et al. 2009) so there may have been a misidentification of the reported host plant. : Published as part of Kanturski, Mariusz & Barjadze, Shalva, 2020, A new species of the aphid genus Uroleucon from Lebanon, with notes on the systematic positions of U. altaicum, U. bielawskii and U. mulgedii (Hemiptera: Aphididae), pp. 548-561 in Zootaxa 4853 (4) on pages 549-553, DOI: 10.11646/zootaxa.4853.4.4, http://zenodo.org/record/4411111 : {"references": ["Holman, J.

There are the seven Palaearctic species currently placed in Uroleucon with 3:3:3 setae on the first tarsal segments: Uroleucon bielawskii , U. dubium Holman, 1975, U. kashmiricum (Verma, 1966), U. mongolicum , U. mulgedii , U. pilosellae (Börner, 1933), and U. telekiae (Holman, 1965) (Nevsky 1928; Szelegiewicz 1962, 1982; Holman 1965, 1975, 1991; Verma 1966). Apterous viviparous females of Uroleucon ( Uroleucon ) lebanonense differ from the same morphs of U. bielawskii, U. dubium and U. mulgedii because they are classified into different subgenera according to the taxonomic criteria used by the authors (Szelegiewicz 1962, 1982; Holman 1975; Blackman & Eastop 2020).Apterae of U. lebanonense differ from the same morphs of U. kashmiricum by ( 1 ) number of secondary rhinaria on ANT III: 45–59 secondary rhinaria in the new species, while 10–30 secondary rhinaria are present in U. kashmiricum , ( 2 ) number of setae on ABD TERG VIII: 4–7 in the new species, while only 2 in U. kashmiricum , ( 3 ) SIPH/cauda ratio: 1.58–1.93 in the new species, while 1.30–1.33 in U. kashmiricum, ( 4 ) presence/absence of antesiphuncular sclerites: fragmented or vestigial sclerites present in the new species, while they are absent in U. kashmiricum (Verma 1966; Blackman & Eastop 2020). From U. pilosellae , the apterous morphs of U. lebanonense may be distinguished by ( 1 ) number of secondary rhinaria on ANT III: 45–59 secondary rhinaria in the new species, while 15–28 secondary rhinaria in U. pilosellae, ( 2 ) fragmented or vestigial sclerites are present in the new species, while large and solid sclerites are present in U. pilosellae (Heie 1995; Blackman 2010; Blackman & Eastop 2020). Apterous viviparous females of U. lebanonense differ from the same morphs of U. telekiae by ( 1 ) number of secondary rhinaria on ANT III: 45–59 secondary rhinaria in the new species, while 6–25 secondary rhinaria in U. telekiae, ( 2 ) URS/HT II ratio: 1.17–1.33 in the new species, while 1.50–1.80 in U. telekiae, ( 3 ) SIPH/BL ratio: 0.20–0.28 in the new species, while 0.32–0.38 in U. telekiae, ( 4 ) number of setae on cauda: 12–18 in the new species, while 20–26 in U. telekiae (Holman 1965; Heie 1995; Blackman & Eastop 2020). Among all known Palaearctic species of the subgenus Uroleucon with 3:3:3 setae on HT I, the new species is most similar to U. mongolicum , with a similar number of setae on ABD TERG VIII (4–7 in the new species and 3–5 in U. mongolicum ). However, apterous viviparous females of U. lebanonense are characterized by several differences in contrast to U. mongolicum : • Mesosternal furca without stem (furca with robust stem in U. mongolicum ); • Cauda with 12–18 setae (Fig. 2g) (cauda with 7–11 setae in U. mongolicum , (Fig. 2h)); • SIPH tapering gradually from base to apex (Fig. 2e) (SIPH with subapical constriction and slightly flared apex (Fig. 2f)); • Lower ratio of SIPH/cauda—1.58–1.93 (1.80-2.60 in U. mongolicum respectively); • Secondary rhinaria with sclerotized rims (fig. 2a) (secondary rhinaria without sclerotized rims in U. mongolicum (Fig. 2b)); • Dorsum of abdomen smooth without reticulation (Fig. 3c) (dorsum of abdomen with well–developed reticulation in U. mongolicum (Fig. 3d)); • Higher ratio of URS/ANT III—0.24–0.26 and URS/ANT VI—0.23–0.25 (0.16–0.21 and 0.16–0.19 in U. mongolicum respectively). Alate viviparous females of the new species can be distinguished from the same morph of U. mongolicum by: • SIPH tapering gradually from base to apex (Fig. 4e) (SIPH with distinctly constricted reticulation area in U. mongolicum (Fig. 4f)); • Secondary rhinaria with sclerotized rims (Fig. 4a) (secondary rhinaria without sclerotized rims in U. mongolicum (Fig. 4b)); • Cauda elongate triangular without constriction near base, with 14 setae (Fig. 4g) (cauda finger–like constricted near base, with 7–11 setae in U. mongolicum (Fig. 4h); • Marginal sclerites on ABD TERG IV smaller than those on ABD TERG III (Figs 1c, 5a) (marginal sclerites on ABD TERG IV as big as or larger than those on ABD TERG III in U. mongolicum (Figs 1d, 5b)); • Higher ratio of ANT IV/ANT V—1.35–1.36, URS/ANT VI—0.23–0.24 and HT II/ANT III—0.19–0.20 (1.22– 1.25, 0.15–0.19 and 0.13–0.14 in U. mongolicum respectively). Etymology. Name of the new species is derived from Lebanon, where it has been collected. Biology and distribution. So far Uroleucon lebanonense is known only from its type locality in the vicinity of Jazzine in Lebanon. Other morphs and life cycle of the new species are unknown. Hille Ris Lambers put the name Tragopogon coloratus as the plant from which the new species has been collected. However T. coloratus is known to be native to Iran, Transcaucasus (including Armenia, Azerbaijan and Georgia) and Turkey (Kilian et al. 2009). In Lebanon there are records for T. buphthalmoides , T. coelesyriacus , T. porrifolius , and T. pterocarpus (Kilian et al. 2009) so there may have been a misidentification of the reported host plant. : Published as part of Kanturski, Mariusz & Barjadze, Shalva, 2020, A new species of the aphid genus Uroleucon from Lebanon, with notes on the systematic positions of U. altaicum, U. bielawskii and U. mulgedii (Hemiptera: Aphididae), pp. 548-561 in Zootaxa 4853 (4) on pages 549-553, DOI: 10.11646/zootaxa.4853.4.4, http://zenodo.org/record/4411111 : {"references": ["Holman, J.
