03C05F02786CFF8E86B5F9F1FF64FB2B.taxon	diagnosis	Diagnosis. The new species, Uroleucon loxdalei sp. nov., is characterized by the colour of the SIPH, which are brown with pale basal section, having 3 – 3 – 3 setae on the first tarsal segments, relatively short PT, pale cauda and poorly developed or pale sclerites and scleroites on the abdomen. The newly designated species is most similar to U. bielawskii (Szelegiewicz), but there are several differences (in apterous viviparous females) as follows: • number of secondary rhinaria on ANTIII: 7 – 19 (27) distributed on 48 – 60 % of the basal part in the new species, while 42 – 69 distributed on the whole length in U. bielawskii; • URS / 2 HT: 0.82 – 1.0 in the new species, while 0.77 – 0.87 in U. bielawskii; • PT / ANTVIb: 2.39 – 3.24 in the new species, while 3.35 – 4.33 in U. bielawskii; • B. D. of SIPH is thinner than B. D. cauda in the new species, while it is thicker in U. bielawskii; • Body length is 2.10 – 2.86 mm in the new species, while 2.9 – 3.38 mm in U. bielawskii; • ANTI & II are dark brown and brown respectively in the new species, while both are light brown in U. bielawskii; • The number of accessory hairs on URS is 8 – 11 in the new species, while 10 – 12 in U. bielawskii (see Table 2) (Szelegiewicz 1962).	en	Mehrparvar, Mohsen, Rakhshani, Ehsan, Rokni, Moein, Kanturski, Mariusz (2022): A new species of the aphid genus Uroleucon Mordvilko, 1914 (Hemiptera Sternorrhyncha: Aphididae) on Launaea acanthodes from Iran.

This aphid lives in sparse colonies on shoots of Launaea acanthodes (Asteraceae) (Fig. 1) which is distributed from north Africa to central Asia. Since all species of Uroleucon are monoecious and in this study sexual morphs have been collected on L. acanthodes in autumn, it therefore can be concluded that this new species has no host alternation and hence is a monoecious, holocyclic species. This aphid is not attended by ants.	en	Mehrparvar, Mohsen, Rakhshani, Ehsan, Rokni, Moein, Kanturski, Mariusz (2022): A new species of the aphid genus Uroleucon Mordvilko, 1914 (Hemiptera Sternorrhyncha: Aphididae) on Launaea acanthodes from Iran.
