Hyadaphis levantina sp. n.

Description. Apterous viviparous females ( Figure 1 ), from 39 specimens, of which 37 have been measured. Colour when alive unknown. When mounted pale in general with brown parts (see details below) and ellipsoid-shaped. Metric and meristic features in Table 1 . Head delicately rough, mainly ventrally, and mostly (including clypeus, labrum and mandibular and maxillar laminae) brown. Triommatidium nearly inconspicuous, quite well integrated into the rest of the eye. Frons gently sinuated. Cephalic dorsal setae stiff and with diffuse apices, blunt or infrequently pointed; ventral setae longer than dorsal setae and pointed. Antennal segments I, II, apex of IV, V (most part) and VI brown; I and II with rough lines and III to VI more or less imbricated. Antennal setae slightly thinner than dorsocephalic setae and pointed. Rostrum reaches or slightly exceeds the middle leg coxae bases and brownish. Ultimate rostral segment triangular in shape, darker than other segments; ventral accessory setae longer than dorsal setae. Legs brown, with coxae, tarsi, apex of tibiae and dorsoapical sector of femora darker than other parts of the legs; tarsi relatively long; setae on tibiae and femora scarce, short, stiff and with diffuse apices, blunt or pointed. Pro- and mesosternal transversal sclerites pigmented and very rough; the prosternal being subrectangular and 0.22–0.35 times as long as wide; the mesosternal being trapezoidal, with the posterior side shorter than the anterior side and 0.43–0.97 times as long as its maximal width. Prothorax with dorsal brown and rough spots; marginal tubercles usually present, round and flat. Both meso- and metathorax with lateroventral areas also rough and brown. Dorsum of the abdominal segment 1–4 usually smooth with light brown marginal sclerites, sometimes very small or absent in some segments; abdominal segments 5 and 6 with spinal and pleural setiferous sclerites and pre- and postsiphuncular sclerites rough and light brown; abdominal segments 7 and 8 with individual brown and spinuled transverse band. Intersegmental sclerites incospicuous. Spiracular sclerites lighter than marginal sclerites. Marginal tubercles usually present on abdominal segments 4–6 and sometimes on segment 3, all of them similar in shape and unlike in size, the anterior ones smaller than the others but usually wider than the length of nearest setae. Dorsoabdominal setae short, stiff and blunt or sometimes pointed. Ventrum of abdomen light and smooth with setae longer than dorsoabdominal ones, stiff and pointed. Siphunculi swollen, brown in general but sometimes the middle part paler; proximally rough, distally with transversal rows of spinules, and with 1 or 2 striae in the constriction below the well defined flange. Cauda finger-like and brown; lateral caudal setae longer than the dorsal caudal setae.

Alate viviparous females ( Figure 2 ), from 9 specimens. Colour when alive unknown. When mounted largely brown (see details below). Metric and meristic features in Table 2 . Mostly, qualitative features similar to those of apterae, which are omitted as well as those characteristic of the winged aphid. Cephalic dorsal and antennal setae blunt or pointed. Antennae brown with decreasing pigmentation to apex. Femoral and tibial setae blunt or pointed. Secondary sensoria on ventral and lateral faces of antennal segments III and IV, and sometimes on V; protuberant, round or elliptical, and with double margin. Abdominal segments 1–6 with individual spinopleural band and marginal sclerites, although sometimes the anterior bands are fragmented or inconspicuous. Siphunculi and cauda pale brown, paler than distal part of femora.

Biology. Hyadaphis levantina sp. n. lives on Lonicera nummulariifolia . No data exists about any migration to umbelliferous species so monoecy of the species is possible.

Distribution. The type specimens were collected in two localities at above 1500 meters a.s.l. in the Eastern margin of the Mediterranean basin; one in the Lebanon mountain range and the other in the southern end of the Anti-Lebanon mountains. The plant host is widely distributed from Anatolia to Afghanistan. It is possible that the aphid accompanies the plant throughout much or all of its distribution area, but it also may be limited to the two indicated mountain ranges, as Kadyrbekov (2000) does not mention it.

Types. Holotype: viviparous apterous female, ISRAEL: Mount Hermon (2200 m.a.s.l.), 7.VI.2001, on Lonicera nummulariifolia ; Y. Bendov leg.; collection of the Muséum national d’Histoire naturelle (Paris, France), sample 0 16718, measured specimen number 9 (on the same slide as that of alatae 1 and 2 plus an alatiform female). Paratypes: 11 apterous viviparous females and 8 alate viviparous females, ISRAEL, same sample and collection as the holotype; and 27 apterous viviparous females and 1 alate viviparous female, LEBANON: near Tannourin Cedars [possibly at not less than 1500 m.a.s.l.], 27.V.1973, on Lonicera nummulariifolia ; D. Hille Ris Lambers leg. (number 787); collection of the Natural History Museum (London, United Kingdom).

Etymology. The specific epithet of the new species, levantina , is a Latin adjective in nominative singular and feminine gender, which means “native of the Levant”; Levant is the appellation of the historical geographical region that include Lebanon, Israel and other neighbouring countries of the Mediterranean oriental slope.
