SYSTEMATIC TREATMENT OF APHID GENERA
(in alphabetical order)
About 12 palaearctic species
associated with Ericaceae and/or Cyperaceae, characterised by apterae having the
front of the head projected forward above and in front of the antennal bases,
either as a ledge or as three lobes.
angusticeps Miyazaki Apterae are elongate oval, pale yellow to
dull yellowish brown, sometimes with a green tint; BL 1.7-2.2 mm. On
undersides of leaves of Carex spp. in
caricis (Fullaway) Plate 20f (Fig.18b,d) Apterae (fundatrices) on Rhododendron spp. yellowish green with
a brownish tinge, or dark reddish brown, with dark siphunculi and cauda; BL
1.6-2.0 mm. Heteroecious holocyclic, migrating to various Cyperus spp. and Kyllinga brevifolia in
Vesiculaphis grandis A.N. Basu Apterae are dark brownish; BL 3.6-4.7 mm. Alatae have dark dorsal spots. On young stems and lower parts of petioles of unnamed Rhododendron spp. in West Bengal, India. Apparently this species does not host-alternate.
kongoensis Takahashi Apterae are unknown, alatae are yellow;
BL of alata 1.7-2.0 mm. On Rhododendron
pieridis A.N. Basu Apterae are yellowish brown, BL 1.7-2.0
mm. Alatae have secondary rhinaria distributed ANT III 44-49, IV 6-7, V 0-1.
On undersides of leaves of Lyonia (=Pieris) ovalifolia in
Vesiculaphis polygonii Bhattacharya & Dey Colour of apterae in life is unrecorded; BL c.1.6-1.7 mm. Alatae are undescribed. Collected from Polygonum alatum in Uttar Pradesh, India (Bhattacharya & Dey 2001). This species is misplaced in Vesiculaphis and is almost certainly a Myzakkaia, possibly a synonym of Myzakkaia verbasci.
Chakrabarti & Medda Appearance in
life is not recorded; apterae are broadly oval, sclerotized, BL 1.7-2.1 mm.
Collected in May on Prunus cornuta
Vesiculaphis rhododendri A.K. Ghosh & Raychaudhuri Colour of apterae in life is not recorded; BL 1.9-2.1 mm. Alatae are undescribed. On Rhododendron sp. in India (Assam, Meghalaya). The life cycle is unknown; viviparae were collected in February (original description), indicating anholocycly.
Vesiculaphis rotunda Miyazaki Apterae are broadly oval, pale green with extensive blackish brown to black sclerotisation of dorsum; BL. 1.2-1.4 mm. Living solitarily on undersides of leaves of Carex siderosticta in Japan. Alatae and life cycle are unknown.
Vesiculaphis sikkimensis Mandal, Agarwala & Raychaudhuri Apterae are brownish, BL 1.2-1.6 mm. Alatae have 15-17 rhinaria distributed along the length of ANT III. In inflorescences of Carex “filicosa” (error for filicina?) in Sikkim, India (Mandal et al. 1979). The life cycle is unknown. To judge from its description, this species clearly belongs in Carolinaia (Juncomyzus), and is closely related to C. scirpus.
theobaldi Takahashi Plate 20g (Fig.18c) Apterae are variable in colour, yellowish
green, pale to mid-green or brownish green to almost black; BL 1.7-2.1 mm. .
Alatae have secondary rhinaria distrubuted ANT III 20-35, IV 8-17, V 4-11. On
undersides of leaves of Carex spp.,
visited by ants, mainly in shady and humid situations. Also recorded from Eriophorum vaginatum (BMNH collection,
leg. R.N.B. Prior) and Scirpus maritimus
(BMNH collection, leg. V.F. Eastop).
Widely distributed in
A genus for one east Asian species related to Sappaphis.
viburnicola (Sorin) Apterae (fundatrices) are bluish green,
dusted with wax powder; BL 2.3-2.7 mm. On young leaves of Viburnum spp. in spring, crumpling and discolouring leaves. In
A genus for one fern-feeding species in China, possibly related to Macromyzella but with low antennal tubercles, a non-spiculose head and siphunculi without subapical reticulation.
Vietaphis aliquanti Su, Jiang & Qiao Apterae yellowish green with dark antennal segments III-VI, pale legs and pale, dark-tipped siphunculi; BL 1.2-1.4 mm. On Plagiogyria japonica, forming loose colonies on undersides of fronds, in Guizhou province, China (Su et al. 2014). Alatae (with secondary rhinaria distributed ANT III 33-37, IV 13, V 2-6) were collected in June. Life cycle is unknown.
Four western palaearctic species associated with Silene, closely related to Aphidura but without mesosternal tubercles, and apterae of three of the species have secondary rhinaria on the distal part of ANT III, or III and IV. Kadyrbekov (2007) provided a key to the apterae of all four species.
alpinae Prior Apterae are pale yellow green powdered
with white wax; BL 1.9-3.0 mm. On Silene
alpina, distorting and discolouring apical parts of plant. In
centaureae (Börner) Apterae are pale green; BL c.1.7-1.8 mm.
Described originally from Centaurea,
but the true hosts are Caryophyllaceae (Lychnis,
Silene, Viscaria), where it
feeds on lower and rosette leaves which are turned upwards and discoloured.
Volutaphis karatavica Kadyrbekov Apterae are yellowish green, with reddish eyes; BL 2.1-2.3 mm. Described from flowers and flower stalks of a plant identified as ?Barbarea arcuata, but probably this was mislabelled (Kadyrbekov 2007), with the true host being a species of Silene (Kadyrbekov 2014f). In southern Kazakhstan (west Tien Shan).
Volutaphis schusteri (Börner) Plate 11h Apterae are yellowish to yellow-green; BL 1.7-2.4 mm. On Silene spp. (latifolia, multiflora), causing yellowing of leaf veins. Widely distributed in continental Europe, and in Turkey, south-west Siberia and Kazakhstan. Monoecious holocyclic, but the male is apparently undescribed (Hille Ris Lambers 1947a, as Silenobium).
