Etymology. This epithet is based on the Greek prefix “ pseudo ” (false) and the New Latin adjective “ sensoriata ” meaning “equipped with sensoria”. Gender: feminine.

Description. Fundatrix. Body broadly elliptical, almost round, 1.1–1.5 times as long as its width. Green, dark green, pale bluish green or yellow-green with brown spots; basal half of antennae, apices of femora and tibiae, tarsi, siphunculi and cauda dark; shiny dorsally, with sparse waxy pulverulence on ventral side. Cleared specimens with almost black basal half of 3rd antennal segment; antennae (except basal half of 3rd antennal segment and processus terminalis), apices of fore femora, middle and hind femora (except base), apices and bases of tibiae, tarsi, siphunculi, subgenital and anal plates and cauda dark brown; two last segments of rostrum, bands on abdominal tergites VII–VIII, rare and small sclerites at the base of setae on other tergites, marginal sclerites and peritremes brown, head, processus terminalis, sclerites at base of coxae, coxae, trochanters, bases of femora and middle parts of tibiae light brown. Dorsal and ventral surfaces of thorax and abdomen are almost completely unsclerotized, with the exception of very rare and small sclerites at the base of setae on dorsal surface of thorax and on abdominal tergites I– VI in some individuals, bands on abdominal tergites VII–VIII, and marginal sclerites; band on tergite VII sometimes can divided into separate sclerites and never fused with marginal sclerites; marginal sclerites on segments I–V are small, inconspicuous, on segments VI and VII large, distinct. Surface of head, dorsal side of thorax, and abdominal tergites I–VI smooth, slightly wrinkled (but Choi et al. (2013) for the fundatrices from Korea indicate that surface of head and thorax is granulose), on surface of abdominal tergite VII with long rows of small pointed spinules, which on abdominal tergite VIII smoothed out and partially fused to form inconspicuous scales. Marginal tubercles always present on prothorax and abdominal segments II–IV and sometimes also on metathorax and abdominal segment I; total number of marginal tubercles on whole body—7–13. Setae on dorsal side of head and thorax and abdominal tergites I–VII pointed, finely pointed or blunt, on antennae, tibiae and tarsi pointed or finely pointed, on abdominal tergite VIII, rostrum, coxae, trochanters, femora, subgenital and anal plates and cauda finely pointed. Chaetotaxy of first tarsal segments 2,2,2, and only occasionally 3,2,2 or 3,3,2. Head with weak traces of epicranial coronal suture. Antennae 5-segmented as a result of fusing of 3rd and 4th segments, without secondary rhinaria or very rarely with only one rhinaria. Rostrum reaching meso-—metathorax. Legs shortened, slightly thickened. Peritremes on abdominal sternites I and II separated by a distance more than diameter of peritreme. Siphunculi with 0–9 relatively long (28–76 μm) finely pointed setae. Cauda rounded escutcheon-shaped. Hind tibiae on apices with 8–26 round pheromone plates.

Systematic relationships. The differences between Neoceruraphis pseudosensoriata ( Pashtshenko, 1988) and N. viburnicola ( Gillette, 1909) are given in the key below.

Distribution. Japan (Mie Prefecture, Ise; Niigata Prefecture, Murakami) ( Sorin 1983; Sorin & Arakawa 2005; Nakatani et al. 2016). Russia (Primorsky Krai: Khasansky District, Kedrovaya Pad Nature Reserve; Partizansky District, Novitskoe Vill.; near Vladivostok, Partizansky urban okrug, Tigrovoy Vill.) ( Pashtshenko, 1988). Korea (Gyeonggi Province, Osan-si, Mulhyanggi Arboretum) ( Choi et al. 2013). China (Beijing, Beijing Botanic Garden and Beijing Purple Bamboo Garden) ( Yu et al. 2018; Yu 2019).

Biology. The primary host are various species of Viburnum : Viburnum opulus L., Viburnum opulus subsp. calvescens (Rehder) Sugim. , Viburnum sargentii Koehne , Viburnum sieboldii Miq. , Viburnum sieboldii var. obovatifolium (Yanagita) Sugim. ( Sorin 1983; Pashtshenko 1988; Sorin & Arakawa 2005; Choi et al. 2013; Nakatani et al. 2016; Yu et al. 2018; Yu 2019). Aphids on Viburnum live on the underside of leaves mainly along large veins, with the edges of the leaf tucking down, the lamina roughly wrinkles along the veins, forming a pale green bulge on the upper side, or the lamina shrinks into a ball, turns red or turns brown. The adult fundatrices on Viburnum were found on April 18 and 30 in Japan, April 23 in Korea, May 31, June 4 and 19 in the Primorsky Krai. The emigrants in the colonies were already on April 27–28 in Beijing ( China), on April 30 and May 5 and 8 in Japan. In Primorsky Krai, emigrants on Viburnum were found from June 10 to July 2, while on July 7 emigrants and the larvae they gave birth were found at the base of Carex stems. There is no doubt, however, that migration begins much earlier, since first time the adult apterous viviparous females (exules) and the larvae born by them were collected on Carex in the Primorsky Krai already on June 29, and in this case the emigrants had to be transferred on Carex in the first half of June. In Beijing, migration begins much earlier, in late April–early May ( Yu 2019). On both Viburnum and Carex , aphids were actively visited by ants; in the latter case, they covered them with an earthen dome at the base of the plant. Autumn morphs of this species are known only from Japan, where gynoparae on leaves of Viburnum were collected on October 27, and males and oviparous females on October 14 and 22 and December 3.

A sample of the species identified as Sappaphis viburnicola Sorin, 1983 collected on 10.v.1981 from the roots of Plantago asiatica L. is available in Dr. Masato Sorin’s aphid collection preserved in the Insect Museum of the National Institute for Agro-Environmental Sciences. Based on these data, Choi et al. (2013) indicate Plantago as a secondary host of Neoceruraphis pseudosensoriata . However, judging by the data obtained on the migration of aphids to Carex , this statement is erroneous, or at least requires further verification.
