Measurements, amounts, and ratios referred by Remaudière (1952) and not observed in the material studied by us from Portugal, Spain, and Italy, are indicated here in parentheses.
Apterous viviparous female. Measurements from 61 specimens (Table 3). Body 1.44– 2.63 mm long. Antennae (1.4) 1.71–2.38 mm long, 0.83–1.28 times as long as body; III antennal segment 0.37–0.65 mm long, with (3) 9–42 secondary rhinaria scattered on 0.5– 0.8 basal part of segment; IV antennal segment 0.29–0.44 mm long and 0.97–1.29 times as long as V, this 0.25–0.39 mm long; base of VI segment 0.13–0.19 mm long; processus terminalis 0.42–0.63 mm long, 3.18–4.00 times as long as base of VI and 0.81–1.15 times as long as III. Primary rhinaria ciliate. Apical rostral segment 0.16–0.21 mm long, 4.00– 5.25 times as long as its basal width, 1.20–1.54 (1.56) times as long as 2nd joint of hind tarsus (this 0.12–0.15 mm long) and 1.05–1.54 times as long as base of antennal segment VI. Secondary hairs of apical rostral segment 5–7 in number, longest 40–70 µm; primary hairs with two pairs near the apical rostrate part of segment and one pair on middle third, near half­length of segment, rarely between middle and apical third of segment. Siphunculi without basal constriction, 0.24–0.55 mm long, with reticulation on apical 50–64%, 0.15–0.25 times as long as body and 1.04–1.46 times as long as cauda. Cauda 0.22–0.40 mm long, 2.17–3.10 times as long as its basal width and 1.28–1.90 times as long as the apical rostral segment. Caudal hairs 8–20. Subgenital plate with 2–4 primary hairs and 7– 13 marginal ones; sometimes with 1–2 supernumerary hairs. First tarsal segments with 3,3,3 hairs. Marginal tubercles absent. Dorsal hairs long, usually blunt to subcapitate but some acute; posterior cephalic hairs 75–119 µm long; spinal hairs on 3rd abdominal tergite 83–125 µm long; hairs on 8th abdominal tergite 4–6, rarely 3, 86–128 µm long. Pronotum with 7–10 hairs. Tibial hairs stout, with several kinds of apex: soft, acute, blunt, subcapitate. Antennal hairs on III segment 29–49 µm long, also with several kinds of apices. Ventral hairs shorter than dorsal ones, mostly blunt but some acute.
Alate viviparous female. Measurements from 39 specimens (Table 4). Body 1.81–2.48 mm long. Antennae 1.81–2.67 mm long, 0.95–1.15 times as long as body; III antennal segment 0.50–0.72 mm long, with 32–68 secondary rhinaria on the whole length of segment; IV antennal segment 0.30–0.50 mm long, 0.94–1.29 times as long as V, usually without secondary rhinaria but rarely with 1–4 (in the Portuguese material) on basal half of the segment; V antennal segment 0.29–0.45 mm long, without secondary rhinaria; base of VI segment 0.13–0.19 mm long; processus terminalis 0.45–0.68 mm long, 3.00–4.00 times as long as base of VI and 0.77–1.03 times as long as III. Apical rostral segment 0.18–0.21 mm long, 3.80–5.25 times as long as its basal width, 1.36–1.58 times as long as 2nd joint of hind tarsus. Secondary hairs of the apical rostral segment usually 6, rarely 5 or 7, the longest 32–75 µm. Siphunculi 0.30–0.46 mm long, with reticulation on apical 43–64%, 0.15–0.22 times as long as body and 1.25–1.64 times as long as cauda. Cauda 0.22–0.32 mm long, 1.92–2.82 times as long as its basal width and 1.10–1.60 times as long as the apical rostral segment. Caudal hairs 8–18. Dorsal hairs shorter than in apterous viviparous females; posterior cephalic hairs 54–88 µm long; spinal hairs on 3rd abdominal tergite 65– 100 µm long; hairs on 8th abdominal tergite 4–5, 63–106 µm long. Antennal hairs on III segment 25–43 µm long. Ventral hairs mostly pointed. Otherwise as in apterous viviparous females.
