Etymology. The species was named in honor of the famous Dutch aphidologist Dick Hille Ris Lambers.
Description. Fundatrix. Body pear-shaped. The living specimen olive brown, wax-powdered except on the middle of the abdominal dorsum. Surface of the first three antennal segments almost smooth. Third antennal segment with 18 secondary rhinaria scattered, secondary rhinaria absent on other antennal segments. Rostrum reaching posterior margin of hind coxae. Cauda triangular, pointed, slightly tapered in the middle.
Apterous viviparous female. Body elongate elliptical, almost spindle-shaped, wide in the middle of abdomen (III–IV segments) and gradually getting narrow to the head and to the end of the abdomen, 1.5–2.3 times as long as wide. The living specimens reddish, with a large black patch on dorsum of abdomen (this patch is absent in macerated specimens), with dark head, antennae, legs (except bases of femora), siphunculi and cauda; eyes red. Cleared specimens with dark brown antennae, distal half of the rostrum, legs (except base of femora) and siphunculi, with brown head, sclerites at the base of the coxae, peritremes, anal plate and cauda, with light-brown subgenital plate, and with very light-brown bands and scleroites on thorax and abdomen. Thorax with more or less wide bands on pro- and mesonotum; abdomen weakly sclerotized, pale, membranous, with peritrems on I–VII segments, rare and very small scleroites at the base of setae, with small and almost invisible antesiphuncular sclerites, with short band on VIII abdominal tergite and sometimes with very short and almost invisible bands or sclerites on VI–VII tergites. Surface of head, thoracic dorsum and abdominal tergites I–V smooth, sometimes weakly wrinkled, on VI– VII abdominal tergites with rows of small pointed spinules, which on VIII abdominal tergite partially fuse to form scales; thoracic venter smooth, ventral abdomen with long rows of small hardly visible spinules, sometimes forming strongly elongate cells. Setae on head, dorsal side of thorax and abdomen very short, strongly blunt, rod-like or very weakly capitate, on ventral side rarely weakly pointed. Third antennal segment with 4–30 secondary rhinaria, fourth segment with 0–6, fifth with 0 rhinaria. Rhinaria with internal diameter 5–25 μm, with external diameter 2.3–9.0 times as long as high of rhinaria. Antennae with very short, strongly blunt, rod-like or very weakly capitate setae. Rostrum is often very long, reaching abdominal segment II–VII. Ultimate rostral segment 3.8–6.4 times as long as its basal width. Setae on legs very short, strongly blunt, rod-like and only in the dorsal half of the tibia on the ventral side, at the very apex of the tibia on the dorsal side and on the tarsi relatively long and pointed. Peritremes on abdominal segments I and II separated by a distance equal to or less than diameter of peritreme, rarely fused. Siphunculi with polygonal reticulation on distal 0.36–0.60 of length (largest transverse row in reticulate part of siphunculi consisting of 4–7 cells). Setae on anal plate short or long, blunt, capitate, pointed or sometimes bifurcate. Cauda nearly triangular, with some constriction in the middle, which divides it into broad base and relatively thin, slightly conical and rounded on apex distal part; setae on cauda are of different lengths—those located closer to the apex are short, blunt, those located further away are relatively long with a flattened and often bifurcated apex.
Alate viviparous female. Body elongate elliptical, 2.1 times as long as wide. The living specimens have the same coloration as the apterous viviparous female. Cleared specimens with dark brown thorax; abdomen with small, light-brown marginal sclerites on segments I–VI, antesiphuncular sclerites absent. Third antennal segment with 23–40 secondary rhinaria, 4th segment with 2–13 and 5th segment with 0–4 secondary rhinaria. Rostrum reaching abdominal segment II–III.
Male. Apterous. Body elongate elliptical, 1.6–2.3 times as long as wide. Colour of living specimens unknown. Surface of abdominal tergite VIII with row of small pointed spinules. Setae on ventral side of body pointed. Third antennal segment with 10–29 secondary rhinaria, 4th segment with 3–13 and 5th segment with 0–6 secondary rhinaria. Setae on antennae, especially on distal segments, sometimes pointed. Rostrum reaching abdominal segment III–V. Setae on legs blunt or pointed. Siphunculi with polygonal reticulation on distal 0.13–0.49 of length (largest transverse row in reticulate part of siphunculi consisting of 4–5 cells). Cauda almost triangular, with very small constriction in the middle, with a very weak division into two parts.
Oviparous female. Body 1.5–2.1 times as long as wide. Colour of living specimens unknown. Tibiae of all legs dark brown only on the apices and brown or light-brown in the middle.Antesiphuncular sclerites on abdomen absent. Third antennal segment with 5–19 secondary rhinaria, 4th segment with 0–1 and 5th segment with 0 secondary rhinaria. Rostrum reaching abdominal segment II–V. Siphunculi with polygonal reticulation on distal 0.28–0.52 of length. Subgenital plate with short rod-like, blunt or pointed setae. Cauda triangular, with very small constriction in the middle. Hind tibiae more or less distinctly swollen on basal half, with 3–44 round or oval pheromone plates, more of them located on basal half.

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.
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 & Wojciechowski 2004, Osiadacz & 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).

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.
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.
