Description

Apterous viviparous female(Fig. 4D). Colour in life unknown. Head yellowish brown to brown. Antennal segments II-III or II-V pigmented like cephalic dorsum, and I and IV-VI or only VI darker than others. Mesosternal mammariform processes rounded, low and pale. Several specimens (holotype included) are pale in general with dark brown intersegmental sclerites, brown postsiphuncular and spiracular sclerites, pale brown setiferous sclerites on abdominal segments 6–8, sometimes coalescing together into transverse bands. The most pigmented specimen has a transverse spinopleural band on prothorax, fragmented bands on mesothorax and abdominal segments 1, 6 and 7, fragmented spinopleural patches on abdominal segments 2–5, and setiferous sclerites on metathorax and abdominal segments 1 and 8. Siphunculi markedly swollen, with stem nearly smooth, and pale or with a smoky apical portion. Cauda triangular, sometimes with a slight constriction near the base, and as pale as the greater part of siphunculi and legs. Genital and anal plates as pale as cauda. Metric and meristic features in Table 3.
Alate viviparous female(Fig. 5A). Head brown, as pigmented as pro- and pterothorax and darker than antennae, tarsi and distal portions of femora and tibiae. Abdominal segments 3–5 with a spinopleural patch, and 7–8 with transverse bands. Siphunculi as dark as pigmented parts of femora. Other qualitative features as in apterae. Metric and meristic features in Table 3.
Male.Winged. Qualitatively very similar to alate viviparous females; with dark parameres. Metric and meristic features in Table 3.

Types

Holotype: Apterous viviparous female (specimen 5), on Silene sp. Kuh-e Dinar (Kohgiluyed and Boyer-Ahmad), Iran, 14-IX-1955, Remaudière leg. (sample i1118a). Paratypes: 15 apterous, 2 viviparous females and 1 male with the same data that the holotype; plus 1 apterous viviparae and 2 alate viviparae on an unidentified species of Caryophyllaceae, Chalus [road to Amol] (Mazenderan), Iran, 3-V-1963, Remaudière leg. (sample i2417).

Etymology

The specific name is a neutral noun in apposition, formed for the Greek words “amphora” and “siphon”, which respectively mean flask and siphon, like in the genus Amphorosiphon.

Discussion

The distinctive features of Aphidura amphorosiphon sp. n. and Aphidura gallica sp. n. are summarized in the identification key to apterae of Aphidura in the general discussion, and in the following modification to the key to aphids on Silene (Blackman and Eastop 2006) for addition of Aphidura amphorosiphon and Aphidura gallica (Aphidura spp. from Iran and from France respectively in that key), and also Aphidura massagetica and Aphidura nomadica, which have been recently described (Kadyrbekov 2013), with deletion of couplets 28 to 34, although several propositions have been partially or completely reutilised:
