SYSTEMATIC TREATMENT OF APHID GENERA
(in alphabetical order)
About six species with elongate
swollen siphunculi, cauda with only 5 hairs and apterae often
without rhinaria on ANT III. One species utilizes Arbutus as secondary hosts.They are mostly of boreal distribution and
associated with Rosa and/or
Ericaceae, their biology thus being like that of Ericaphis which are probably their closest relatives. Accounts
are available for western Europe (Hille Ris Lambers 1949, Heie, 1995) and
Wahlgreniella empetri Richards Apterae are dull green with dusky appendages; BL 1.5-1.8 mm. Alatae have dark brown to black head, antennae and thorax. On Empetrum nigrum in northern Canada (Baffin Island).
lampeli Rupais Apterae are shining lemon-yellow; BL
2.1-2.6 mm. On Empetrum hermaphroditum in
northern Russia (
(Gillette) Plate 24d Apterae
are spindle-shaped, pale yellow-green to dull mid-green, with dark-ringed
antennae and dark tips to the long, slightly swollen siphunculi (see influentialpoints.com/Gallery);
BL 1.4-2.5 mm. Alatae have a green abdomen with variably developed dark
dorsal cross-bands, sometimes coalesced into an irregular patch. In western
North America it is apparently host-alternating between Rosa and Ericaceae (Arbutus, Arctostaphylos, Pieris),
although the host alternation still awaits proper experimental verification. Introduced populations on roses occur in Central
and South America, Europe, Saudi Arabia (Hussain et al. 2015),
ossiannilssoni Hille Ris
Lambers Apterae are shining pale
yellow, dark green, reddish brown or greenish black, with siphunculi dark in
middle and at tips; BL 1.5-2.3 mm. On undersides of leaves and shoots of Arctostaphylos uva-ursi. Boreo-alpine
in distribution (northern Europe, Balkans,
vaccinii (Theobald) (Fig.56e) Apterae are shining greenish yellow or
yellowish green, and have antennae ringed with black; BL 1.6-2.3 mm. On the
undersides of leaves of Vaccinium spp.
Wahgreniella viburni (Takahashi) Apterae are green, with tips of siphunculi dusky; BL c.2 mm. Alatae have secondary rhinaria distributed III c.45, IV 8-10, V 0-3. It was described from alatae found in Taiwan collected on young leaves of Viburnum arboricola (= V. odoratissimum var. iwabuki), but apterae and alatae of apparently the same species were collected on Mahonia morrisonensis (= M. oiwakensis), so the true host is in doubt. An association with Mahonia would indicate that this species may belong in Liosomaphis, and is possibly synonymous with L. himalayensis.
One species in
amblyopappos (Zhang & Zhang) Only apterae are known, collected on Quercus liaotungensis in
A genus for one species in east Asia which probably alternates between Maloideae and Pinus roots, although so far only known from the alate sexupara. It may be a small species of Prociphilus.
Watabura nishiyae Matsumura This species was described from alate ?sexuparae collected on Cydonia in Japan (Matsumura 1917). Sexuparae that appear to be the same species have subsequently been collected from roots of Pinus spp. (densiflora, thunbergii) in Japan (BMNH collection, leg D. Hille Ris Lambers), and from twigs and branches of a cultivated Malus sp. in Korea (BMNH collection, leg. V. F. Eastop). The sexuparae are small (BL 1.3-1.9 mm), wax-dusted in life (V.F. Eastop, unpublished observation), with secondary rhinaria distributed III 11-16, IV 4-10, V 5-10, VI 3-9. The spring generations on Malus and the apterous exules on Pinus roots have not been described. This species was confused in the literature for many years with Aphidounguis mali, and records of Watabura nishiyae from Ulmacaeae and roots of Malus apply to that species.
