Zootaxa 2014 3760 4 563 570 Chakrabarti & Medda, 1993 Chakrabarti & Medda 1993 [151,711,1321,1347] Insecta Aphididae Dysaphis Animalia Aphidomorpha 0 563 Arthropoda species indica stat. nov.  Hitherto  Dysaphis pavlovskiana, sensu strictowas known from Eastern and Western Siberia, Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistanand Pakistan( Narzikulov 1957; Ivanovskaya, 1977; Gabrid, 1989; Kadyrbekov, 1990; Naumann-Etienne & Remaudière, 1995; Stekolshchikov & Shaposhnikov, 1998; Holman, 2009). Slides have now been studied of aphids collected by G. Remaudière on 17 June 1966from  Sorbus graeca(Lindl.) Fritsch & Rech.in Turkey(Konya, Ereğli) at an altitude of 2000 mabove sea level and stored in the aphid collection of Muséum national d'Histoire naturelle. This sample contains four fundatrices, eight apterae and 34 alate viviparous females. These aphids are very similar to  D. pavlovskianahoused in the Russian collections in all characters, differing from them only by the greater length of the ultimate segment of the rostrum and its relation to the length of 2nd segment of hind tarsus, as well as having more long setae on the body and appendages. However, if we consider the variation in these characters in different populations of  D. pavlovskiana( Tabl. 1), we see that when going from north to south, not only the absolute length of the ultimate segment of the rostrum but its ratio to the length of 2nd segment of hind tarsus increases, and this phenomenon is more or less clearly expressed for all morphs for which it is possible to make a comparison. A similar, though less clearly expressed situation is observed with the length of setae. Individuals from Turkeyare thus just an extreme variant on the line of these changes, conforming completely to this trend and undoubtedly belonging to the species  D. pavlovskiana.   TABLE 1.Length of ultimate segment of rostrum and ratio of ultimate segment of rostrum to 2nd segment of hind tarsus for different populations of  Dysaphis pavlovskianaNarzikulov, 1957and  D. indicaChakrabarti & Medda, 1993.      Dysaphis pavlovskianaEastern Siberia Kazakhstan Tajikistan Turkey   Dysaphis indica  Fundatrices Ultimate segment of rostrum 135–160 143–154 151–168 (135–146) (150) (157–161) 188–195 (192) –  Ultimate segment of rostrum/ 2nd segment of hind tarsus 1.05–1.28 1.16–1.33 1.32–1.51 (1.11–1.19) (1.22) (1.44) 1.64–1.86 (1.77) –  Apterous Ultimate segment of rostrum from Sorbus – – 123–149 (135–142) 160–182 (173) 200–220  Ultimate segment of rostrum/ 2nd segment of hind tarsus – – 0.94–1.17 (1.08–1.13) 1.18–1.50 (1.39) 1.33  Emigrants Ultimate segment of rostrum 115–140 107–135 123–151 (126–133) (126) (128–141) 155–176 (165) –  Ultimate segment of rostrum/ 2nd segment of hind tarsus 0.84–1.02 0.83–1.04 1.00–1.23 (0.95) (0.96) (1.11) 1.38–1.59 (1.47) –  Apterous Ultimate segment of rostrum exules 101–121 109–118 112–123 (113) (112) (116) – 210–220  Ultimate segment of rostrum/ 2nd segment of hind tarsus 1.05–1.29 1.10–1.17 1.08–1.37 (1.11–1.18) (1.14) (1.21) – 1.31–1.35  Gynoparae Ultimate segment of rostrum – – 107–121 (114) – 160 1  Ultimate segment of rostrum/ 2nd segment of hind tarsus – – 1.00–1.24 (1.12) – 1.13–1.14  1 — only one specimen. The situation is different with  Dysaphis pavlovskiana indica Chakrabarti & Medda, 1993. In  indicathe absolute length of the ultimate segment of the rostrum is greater than in  pavlovskiana s.str., but the ratio of the length of the ultimate segment of the rostrum to the length of the second segment of hind tarsus does not differ ( Table 1). In addition,  indicadiffers from  pavlovskianain the following characters (apart from those listed in the original description): body length (  indicalonger), ratio of length of processus terminalis to length of base of last antennal segment (greater in  indica, especially for the morph from  Saussurea), longer cauda (at least for morph from secondary host), number of rhinaria on the segments of antenna of gynoparae (more in  indica), and by some other characters (Table 2). Information about the length of setae of apterous females of  indicafrom  Sorbusis absent from the original description, but morphs of  indicafrom the secondary host have longer setae than the respective morphs of  pavlovskiana. However, as stated above, this character has no significant value in the taxonomy of this group. Apterous exules of  pavlovskianafrom  Plantagoare strongly sclerotized, with sclerotic bands from meso- or metathorax to VII abdominal tergite fused with marginal sclerites and forming a complete dorsal shield. Apterae of  indicafrom  Saussureaare almost unsclerotized, having only a sclerotized band on abdominal tergite VIII. The secondary host of  indicais  Saussurea, whereas  pavlovskianamigrates from  Sorbusto  Plantago( Shaposhnikov, 1974; Stekolshchikov & Shaposhnikov, 1998). These significant differences between  indicaand  pavlovskianain morphology and, more importantly, in biology (a different secondary host) indicate that it as a separate species—  Dysaphis indica Chakrabarti & Medda, 1993 (new status).   D. indicais undoubtedly very closely related to  D. pavlovskianaand they have a common ancestor that may have migrated from  Sorbusin the second and third generation to a more-or-less wide range of secondary hosts. This ancestor had a long ultimate segment of the rostrum, long thin setae, slightly swollen or unswollen siphunculi, and strongly sclerotized apterous viviparous females on  Sorbusand on secondary hosts. After separation  D.indicaapparently remained in a relatively narrow area within the Himalayas, while  D. pavlovskianabecame widespread in Eurasia—from Turkeyto Eastern Siberia. Asalready pointed out ( Stekolshchikov & Shaposhnikov, 1998), the spread of  D. pavlovskianafrom south to north was accompanied by some changes in its morphology and, more importantly, in its biology; both emigrants and apterous viviparous females are among the offspring of the fundatrix in populations of Tajikistanand Turkey(in Tajikistanapterae are found on  Sorbusuntil the 5th generation), but there are no apterae on Sorbusin the Kazakhstanand East Siberian populations, the fundatrix producing only alatae females—emigrants.
