            <p> Subgenus  Ramitrichophorus Hille Ris Lambers, 1947</p>
            <p> Type species:  Macrosiphoniella (Ramitrichophorus) janckei Börner, 1939</p>
            <p>Description. Body elliptical or elongate elliptical. Thorax of apterous morphs with more or less wide bands on pro- and mesonotum. Abdominal dorsum of all morphs weakly sclerotized, with or without small spinal and marginal sclerites, antesiphuncular sclerites and bands on abdominal segments VII and VIII. Setae on body and appendages different types (Figs. 1–3). Marginal and spinal tubercles absent. Head without epicranial suture or very rare with its weak traces. Frontal tubercles weakly developed, median tubercle absent, antennal tubercles visible, but not high, divergent, with a shallow frontal sinus between them, sometimes frons nearly straight. First and second antennal segments slightly wrinkled, almost smooth, 2nd segment ventrally with rare short scales, 3rd–6th segments with large scales which are almost invisible on basal part of 3rd segment and well-defined on 5–6th segments. Antennae 6-segmented, secondary rhinaria are present on third, and sometimes on fourth and fifth antennal segments in all morphs, they round or oval, not large, weakly protuberant and scattered not in a row along one side of the segment almost from basis to apex in case of a large number of rhinaria. Rostrum long. Ultimate rostral segment long and narrow, nail-like—comparatively wide at the very base, tapering just after the base, then almost parallel-sided and pointed at the apex. Legs normal. Chaetotaxy of first tarsal segments 3, 3, 3 (rarely on one leg the first tarsal segment has 2 or 4 setae). Arms of mesosternal furca connected by wide base. Spiracles reniform. Siphunculi subcylindrical, gradually tapering towards apex, rarely slightly curved outwards, with small flange and polygonal reticulation, distinctly imbricated, with short rows of pointed spinules at the base that fused into large scales in front of the reticular part. Subgenital plate oval. Central part of anal plate protruding in the form of tubercle directed downwards. Cauda nearly triangular, with some more or less evident constriction in the middle, which sometimes divides it into broad base and relatively thin, slightly conical and rounded on apex distal part.</p>
            <p>Etymology. The name of the subgenus is a compound of word „rami“—plural from Latin „ramus“ (branch), the New Latin word „tricho“ origin from Greek „thrix“ (hair), element „-phor-“—from the Greek verb „phoro“ (carry) and the Latin masculine ending „-us“. This name was given to this subgenus for the presence on the body of individuals of the type species a large number of ramose apically long setae. Gender: masculine.</p>
            <p> Diagnosis. The subgenus  Ramitrichophorus differs from other subgenera of the genus  Macrosiphoniella in the following combination of characters: a long, almost nail-like ultimate rostral segment, triangular, often with a significant constriction in the middle cauda, weakly developed frontal tubercles, with a shallow frontal sinus between antennal tubercles (sometimes frons nearly straight), and location of most of the secondary rhinaria along one side of the third antennal segment. </p>
            <p> Several authors considered  Ramitrichophorus as an independent genus. So Kadyrbekov (2017) indicates that  Ramitrichophorus is „close to the genus  Macrosiphoniella Guerc. , but differs from it in the presence of a single rounded protuberance on the anal plate, at least 6 setae on the disc of the genital plate, pointed, forked, tridentate, fanshaped dorsal setae". Therefore Kadyrbekov assigns generic status to  Ramitrichophorus . The presence of 6 setae on the disc of the genital plate, as well as setae of the indicated shape, is found in different species of  Macrosiphoniella , especially since the shape of the setae in species of  Ramitrichophorus is different and the character that separates the species cannot be at the same time a common character of the genus. The anal plate with rounded protuberance, although less pronounced, is found in a number of species  Macrosiphoniella . Moreover, this character is not unique within  Macrosiphoniella , the anal plate strongly protruding in the form of a tubercle is also found in species of other genera, such as  Microsiphum Cholodkovsky, 1902 ,  Microsiphoniella Hille Ris Lambers, 1947 , and  Brevisiphonaphis Stekolshchikov et Qiao, 2008 . The set of characters that distinguish  Ramitrichophorus species from other species of the genus  Macrosiphoniella does not make the difference between them significant and, in our opinion, is at the level of intrageneric rather than intergeneric differences, which allows us to continue to consider  Ramitrichophorus as a subgenus of the genus  Macrosiphoniella . </p>

            <p> Systematic relationships. Described in 1957 by Bozhko  Ramitrichophorus paradoxus , like  M. (R.) hillerislambersi , has very short setae all over the body and appendages and practically does not differ from it in other characters, with the exception of the slightly longer processus terminalis and the ultimate rostral segment in several individuals of  M. (R.) paradoxa (Table 1). Such small differences can be explained by inter-population variability within the species' area. Thus, a high degree of morphological similarity allows us to place  Macrosiphoniella (Ramitrichophorus) paradoxa (Bozhko, 1957) as a new subjective synonym of  Macrosiphoniella (Ramitrichophorus) hillerislambersi Ossiannilsson, 1954 . </p>
            <p> Distribution. Sweden (Skåne County, Åhus) (Ossiannilsson 1954, 1959, 1964), Denmark (Central Jutland Region, Syddjurs municipality, Mols) (Heie 1965, 1969, 1995), Germany (Mecklenburg-Vorpommern, Feldberger Seenlandschaft) (Müller 1975), Poland (Podlasie Voivodeship, Mońki County, near Dolistowo Stare Vill.) (Szelegiewicz 1978, Czylok et al. 1982, Nast et al. 1990, Węgierek &amp; Wojciechowski 2004, Osiadacz &amp; Hałaj 2010), Czech Republic (South Moravian Region, Bzenec) (Holman 1965), south of the Slovak Republic, Russia (Stavropol Krai, Neftekumsky District, near the village Achikulak) (Bozhko 1957, 1976, as  Ramitrichophorus paradoxus ), Kazakhstan (Aktobe Region, Temir District, near Shubarkuduk Vill.; Karaganda Region, Zhanaarka District, northeast of the Kyzylzhar railway station; East Kazakhstan Region, valley of the Irtysh River) (Smailova 1980, as  Macrosiphoniella janekei, Kadyrbekov 2014, 2017 ). </p>

            <p> Rakauskas et al. (2008) list this species for the territory of Lithuania —“Pervalka, 7 July 2004 (Ra 04-83)”, however, a study of the materials of this sample, stored in the collections of ZIN and MNHN, showed that this specifying is based on an erroneous identification of the material. All slides contained only  M. (R.) janckei and, accordingly,  M. (R.) hillerislambersi should be excluded from the list of aphids inhabiting the territory of Lithuania. </p>
            <p> Biology. The host plants are  Helichrysum arenarium (L.) Moench and  Helichrysum sp. It was found on subterraneous parts of the plant, attended by ants  Lasius niger (L.) in Sweden (Ossiannilsson 1954), on the root collar with ants in Germany (with  Formica rufa L.) (Müller 1975) and in Poland (Czylok et al. 1982), and above ground level in Denmark (Heie 1965), but on the tops of shoots between flowers in the North Caucasus (Russia) (Bozhko 1957, 1976). The collection of IE BC CAS also contains a single sample of this species made by J. Holman in autumn 1962 from  Achillea nobilis L. in the south of the Slovak Republic. The aphid colony consisted of a single apterous viviparous female, two males and numerous oviparous females. Kadyrbekov (2017) cites collection data of this species made in Kazakhstan by N.E. Smailova from  Arctium tomentosum Mill. (East Kazakhstan: No 3703, 3708, East Kazakhstan region, valley of the Irtysh River, near Proletarka Vill., 18.07.1981). The sample included 7 apterous viviparous females, which, if no mistake was made in the plant identification, confirms the possibility of  M. (R.) hillerislambersi for at least some time to feed and even form colonies on other  Asteraceae , besides  Helichrysum . </p>

Pervalka and Neringa, Nida)(Rakauskas et al. 2008, as  Macrosiphoniella (Ramitrichophorus) janckei and  M. (R.) hillerislambersi ), Belarus (Minsk Region, Maladzyechna District, near Udranka Vill. (Buga &amp; Stekolshchikov 2012), Moldova (Autonomous Territorial Unit of Gagauzia, Vill. Bugeac) (Vereshchagin et al. 1985; Andreev &amp; Vereshchagin 1993 as  Macrosiphoniella medvedevi ), Ukraine (forest-steppe and steppe zones) (Bozhko 1963, 1976), Russia (Pskov Province, Nevel` District, near Dubokray Vill.; Stavropol Krai, Stepnovsky District, Irgakly), Kazakhstan (West Kazakhstan Region, Terekti District, east of Uralsk; Atyrau Region, Makhambet District, near Makhambet Vill. and Isatay District, near Isatai Vill.; Aktobe Region, Shalkar District, near Shalkar; Akmola Region, Birzhan sal District, east of Stepnyak; Karaganda Region, Ulytau District, south-west of Ulytau Vill.; Almaty Region, right bank of the river Ili) (Kadyrbekov 2003, 2017). </p>
            <p> Ivanovskaya (1977) records this species from the Altai Republic (Russia) on the basis of nine immature of the third instar collected on an unknown  Asteraceae . On the basis of these data, many researchers in their later publications indicate Western Siberia as part of the area of this species. However, any reliable identification based on such material seems very doubtful and, therefore, there are no reliable data on the finding of this species in Western Siberia and Altai (see Stekolshchikov &amp; Novgorodova 2015). </p>
            <p> Biology. The species lives on stems, inflorescences and the lower surface of leaves of  Helichrysum arenarium (L.) Moench, actively attended by ants (Szelegiewicz 1968, Bozhko 1976, Kadyrbekov 2003, Buga &amp; Stekolshchikov 2012). This species has never been observed on other species of the genus  Helichrysum or plants of other genera. Colonies of these aphids in Belarus and the Pskov Province of Russia were always collected from beneath the inflorescences and from stems of  H. arenarium . All these colonies were attended by ants  Formica cinerea Mayr. Apterous males and oviparous females of  M. (R.) janckei were found in Germany (Rostock, Laage) by Müller (1975) on 28.ix.1970, and a single oviparous female only was found together with apterous viviparous females in Russia (Pskov Province, Nevel` District, near Dubokray Vill.) in August 2016. </p>

            <p> Systematic relationships. The species is very close to  Macrosiphoniella (Ramitrichophorus) janckei Börner, 1939 . The differences between them are given in the keys. </p>
            <p>Distribution. Germany (Mecklenburg-Vorpommern) (Müller 1969), Poland (West Pomeranian Voivodeship, Świnoujście and Kamień County, Międzyzdroje; Warmian-Masurian Voivodeship, Olsztyn; Kuyavian-Pomeranian Voivodeship, Bydgoszcz; Greater Poland Voivodeship, Poznań; Mazovian Voivodeship, Otwock County, Otwock; Podlasie Voivodeship, Mońki County, near Dolistowo Stare Vill.; Pomeranian Voivodeship, Nowy Dwór Gdański County, Krynica Morska) (Szelegiewicz 1958a, 1958b, 1967, 1968, 1974, 1975, 1978; Huculak 1965; Achremowicz 1967, 1975; Czylok et al. 1982; Nast et al. 1990; Węgierek &amp; Wojciechowski 2004; Osiadacz &amp; Hałaj 2010), Russia (Moscow Province, Serpukhovsky District, Luzhki Vill.), Ukraine (Kharkiv Province, Chuhuiv District, near Zmiiv) (Bozhko 1950, 1963, 1976), Kazakhstan (?) (Aktobe Region, near Aktobe and in Temir District, near Kalmakkyrgan railway station) (Smailova 1980), Iran (Rezwani et al. 1994).</p>
            <p> Smailova (1980) indicates that two samples of  M. (R.) medvedevi were collected from stems and pedicels of  Helichrysum arenarium in Kazakhstan (Aktobe Region: near Aktobe and in Temir District, near Kalmakkyrgan railway station). Aphid colonies consisted of apterous viviparous females and immatures of 2–3 instars. However, Kadyrbekov in his summary on the fauna of aphids of Kazakhstan (2017) does not give this species for this territory, indicating that only two species have been found in Kazakhstan —  M. (R.) janckei and  M. (R.) hillerislambersi . Thus, the presence of  M. (R.) medvedevi in Kazakhstan remains doubtful. </p>
            <p> Biology. The species lives on stems, inflorescences and the lower surface of leaves of  Helichrysum arenarium (L.) Moench, always attended by ants (Szelegiewicz 1958a, 1958b, 1967; Huculak 1965; Czylok et al. 1982), including  Formica cinerea Mayr. (Szelegiewicz 1958a) . Apterous male and oviparous females of  M. (R.) medvedevi were found in Poland (Kuyavian-Pomeranian Voivodeship, Bydgoszcz) by Szelegiewicz on 20.ix.1962. </p>
            <p> Previously, another species—  Macrosiphoniella nikolajevi Kadyrbekov, 1999 —was included in the subgenus  Macrosiphoniella . </p>

            <p>(Figs. 64–70, Tabl. 6)</p>
            <p> Material.   Paratype: 5 apterous viviparous female, „  Macrosiphoniella nikolajevi sp. n. ,  Helichrysum maracandicum , W. Kazakhstan,  Kyrgyz Ridge , Makpal gorge, H—1500, 20.vii.1996, Nikolaev G. V.” (from the collection of ZIN RAS)  . </p>
            <p>Etymology. The species was named in honor of the famous Soviet Kazakh entomologist Georgiy Vladimirovich Nikolaev, who first collected this species.</p>
            <p> Systematic position. Kadyrbekov reffered  Macrosiphoniella nikolajevi to the subgenus  Ramitrichophorus on the basis of the shape and length of the ultimate rostral segment, as well as the belonging of its host plant to the genus  Helichrysum , with which all other species of this subgenus are associated. At the same time, he pointed out that the new species sharply differs from all species known in this subgenus by the large number of secondary rhinaria on the third antennal segment, their absence on the fourth segment of apterous viviparous females, the type of dorsal sclerotization, the shape of the cauda, very long and thick setae on the body, antennae and legs (Kadyrbekov 1999). Later, he began to consider the species as part of the nominative subgenus without explaining the change in its taxonomic status (Kadyrbekov 2017). The complete absence of rhinaria on the fourth segment of the antennae is typical for most individuals of the species of the subgenus, and  M. (R.) medvedevi has long and numerous setae, but the rest of the listed characters really clearly distinguish  nikolajevi from other species of  Ramitrichophorus . This is especially evident in the example of the shape of the cauda—triangular, acute and with a small number of setae in all species of  Ramitrichophorus (one of the characters on the basis of which Hille Ris Lambers (1947) actually distinguished the subgenus) and typical for most other  Macrosiphoniella elongate fingershaped, with constriction in the basal half and often with numerous setae (as in  nikolajevi ). The setae on the ultimate rostral segment of  nikolajevi , like in most  Macrosiphoniella , are long, while the setae located closer to the base of the segment are significantly longer than the setae on the apex of the segment, which also distinguishes it from all species of  Ramitrichophorus in which all setae on the last segment of the rostrum are short and of approximately equal length. In addition, the species differs from all species of  Ramitrichophorus in the shape of the ultimate rostral segment—in  Ramitrichophorus species it is "nail-like" (with a slight extension at the base, then with almost parallel edges and pointed at the apex), while in  nikolajevi , the ultimate rostral segment is elongated wedge-shaped, more or less gradually tapering towards apex typical enough for most  Macrosiphoniella . Thus, the morphological similarity between other species of  Ramitrichophorus in  nikolajevi is practically limited only by the long length of the ultimate rostral segment, which may be explained rather by convergence associated with the similarity of the host plant rather by phylogenetic relationship. </p>
            <p>Distribution. Kazakhstan (Jambyl Region and Turkistan Region) (Kadyrbekov 1999, 2002, 2017), Iran (Tehran Province, Alborz Province, Isfahan Province) (Kanturski &amp; Barjadze 2018; Momeni Shahraki et al. 2019).</p>
            <p> Biology. Lives on the stem and under the flowers of  Helichrysum maracandicum Popov in scattered colonies. </p>
