SYSTEMATIC TREATMENT OF APHID GENERA
(in alphabetical order)
Four species related to Myzus but with distinctive siphunculi. One species, J. sikkimensis M.R. Ghosh, R.C. Basu & Raychaudhuri, is described from alatae only, on an unidentified grass in India. Another, J. gibbera Qiao, Li, Zhang & Su is described from an unidentified leguminous plant in Shaanxi province, China. Li et al. (2013) reviewed the genus and provided a key to apterae.
Jacksonia campanulata Chakrabarti & Raychaudhuri
Appearance in life is unrecorded ; BL c.1.0-1.1 mm. On Campanula spp. in northern
Jacksonia papillata Theobald Plate 18c Apterae are brownish green, olive-green,
dull greenish yellow or reddish, slightly wax-powdered on underside, with
brown head, antennae and legs, dark-tipped siphunculi and dark cauda; BL
1.5-1.9 mm. Alatae are rare; they are dark green with an extensive dark
sclerotic pattern, and secondary rhinaria distributed III 20-32, IV 7-18, V
1-6. On various grasses (Dactylis, Deschampsia, Festuca, Poa), living
cryptically on colourless basal parts of stems, not visited by ants. Often
recorded from moss samples, not surprisingly in view of its habitat, but it
is suspected to sometimes feed on mosses (Müller 1973b), and there are also
records, probably casual occurrences, from potato (original description), Lysimachia and Veronica (Heie 1994), and several other plants in diverse families.
In regions with temperate oceanic climates throughout the world, including
many oceanic islands (e.g.
One species associated with Juncus, closely related to Iziphya. The antennal terminal process is very short, and the dorsal hairs are all fan-shaped and without tuberculate bases. Quednau (2010) illustrated apterous and alate vivparae.
Juncobia leegei (Börner) Plate 4e Apterae are yellowish with blackish grey
markings; BL 1.6-1.9 mm. On leaves of Juncus
spp., in wet situations visited by ants. The original host record from Carex was in error – see Börner
