Name

Aleurodaphis van der Goot, 1917 – Wikispecies link – Pensoft Profile

• Aleurodaphis van der Goot, 1917: 239.
• Aleurodaphis van der Goot: Baker 1929: 86; Takahashi 1931: 92; Takahashi and Sorin 1958: 31; Raychaudhuri et al. 1980: 36; Ghosh 1988: 249; Noordam 1991: 47; Tao 1990: 58; Blackman and Eastop 1994: 551; Remaudière and Remaudière 1997: 181; Tao 1999: 17.

Type species

Aleurodaphis blumae van der Goot, 1917.

Diagnosis

Body oval and flat. In apterous females: body aleyrodiform, absence of frontal horns, and wax glands arranged along the crenulated margin of body. Head and prothorax, meso- and metathorax, abdominal tergites I–VII fused, respectively; only abdominal tergite VIII free; antennae 4 or 5-segmented, primary rhinaria small and ciliated; eyes with 3 facets. Dorsal setae fine and sparse. Rostrum reaching mid-coxae, at most hind coxae. Ultimate rostral segment obviously longer than second hind tarsal segment. Legs short; first tarsal chaetotaxy: 2–4, 2–4, 2–4; dorsal-apical setae on second hind tarsal segments with funnel-shaped apex. Siphunculi ring-shaped. Cauda knobbed and anal plate bilobed. In alate viviparous females: antennae 5-segmented, with secondary rhinaria near ring-shaped, without cilia; eyes normal; first tarsal chaetotaxy: 4, 4, 4, sometimes 3 or 2; fore wings with media once branched, pterostigma extended and two cubitus fused or separated at base; hind wings with two obliques.

Host plants

The range of host plants in Aleurodaphis is quite wide, including Compositae (Aster, Blumea, Carpesium, Chrysanthemum, Kalimeris, Ligularia, Parasenecio, Senecio), Balsaminaceae (Impatiens), Gramineae (Bambusa), Moraceae (Ficus), Plantaginaceae (Plantago), Scrophulariaceae (Mazus), Styracaceae (Sinojackia), Theaceae (Stewartia), Verbenaceae (Callicarpa) and Violaceae.

Biology

Five species, Aleurodaphis asteris, Aleurodaphis blumeae, Aleurodaphis impatientis, Aleurodaphis ligulariae and Aleurodaphis mikaniae, mainly feeding on Compositae species, have monoecious and anholocyclic life cycle. Aleurodaphis sinojackiae Qiao & Jiang, sp. n. and Aleurodaphis stewartiae can form galls on the leaves of the primary host plants, but their secondary hosts are unknown. The details of Aleurodaphis antennata wereunreported (Ghosh 1988; Blackman and Eastop 1994, 2006; Sorin and Miyazaki 2004).

Distribution

China, Japan, India and Indonesia.
