(Figures 14–24, Table 1)
Material examined. Holotype: apterous viviparous female, slide N 0 3787, specimen No. 1 (lower specimen on the right side), Northern Turkey, Çankırı Province, Ilgazdağ, N 41 0 0 5/, E 33 0 44 /, 1100 m a.s.l., 24.VI.1966; on Matricaria sp., leg. G. Remaudiére; Paratypes: 3 apterous and 2 alate females on two slides, the same data as for holotype. Type specimens are deposited at the Natural History Museum in London (BMNH).
Etymology. The specific name is derived from a noun, the genus name of the host plant of the aphid, Matricaria (Asteraceae), in genitive.
Description. Apterous viviparous females (4 specimens /1 sample).
Color in living specimens: unknown. Color on slide: ANT I, II, V and VI brown; ANT III pale; ANT IV pale except apices, head, rostrum, coxae and trochanters brown; femurs brown except basal parts; tibiae brown except apices; tarsi brown (fig. 21); SIPH and cauda brown, concolorous; subgenital and anal plates brown; ABD TERG VII–VIII with dusky bands; presiphuncular and postsiphuncular sclerites absent; in pigmented form: intersegmental gland sclerites present on ABD TERG I–V; different sized and shaped sclerites are developed on ABD TERG I–V, from which relatively large ones are on ABD TERG IV–V; in pale form: intersegmental gland sclerites and sclerites on ABD TERG I–V absent (figs. 14–15).
Morphological characters: body oval (figs. 14–15); BW 0.68–0.73× BL. ANT 5- or 6-segmented (in one of the four specimens one antenna is 5-segmented and the other 6-segmented). PT 1.65–2.04× ANT VI b. ANT III without sec. rhin. (fig. 22). Number of hairs on each ANT segment: ANT I 4–5, ANT II 4, ANT III 3–7, ANT IV 3–4, ANT V 2–4, ANT VI b 2–3, PT 1–2 (additional). Frons with w-shaped outline in dorsal view. Rostrum reaches beyond middle coxae. URS pointed, with 2 accessory hairs (fig. 18), its length 0.90–0.97× ANT VI b and 0.84–0.87× HT II. Posterior hair on hind trochanter 0.80–1.12× diameter of trochantro-femoral suture. HTC: 3:3:2. ABD TERG I and VII with small mammariform MTu (21–35 µm of diameter). Marginal hair on ABD TERG I 0.70–0.96× diameter of the MTu on the same tergite, ABD TERG II–VI without MTu. Diameter of MTu on ABD TERG I 1.09–1.52× ANT III BD and 0.79–1.29× diameter of MTu on ABD TERG VII. Diameter of MTu on ABD TERG VII 0.88–1.38× ANT III BD and 0.30–0.47× basal width of SIPH. SIPH cylindrical, strongly imbricated, with normal flange (fig. 20), its length 2.20–3.22× its width in the middle and 0.65–0.80× cauda. ABD TERG VIII with 2 hairs. Subgenital plate oval, with spinulose imbrications and 2–3 hairs on the anterior disc and 8–12 hairs on posterior margin (fig. 17). Cauda finger-like, parallel-sided on distal two-thirds and bearing long, curved 7–8 hairs and numerous strong black spinules (fig. 19). Morphometric data are given in Table 1.
Alate viviparous females (2 specimens /1 sample)
Color in living specimens: unknown. Color on slide: Head and all ANT segments, thorax, rostrum, coxae, trochanters, SIPH, subgenital and anal plates and cauda brown, femurs brown except basal parts; tibiae brown except apices; tarsi brown; ABD TERG I–VI with different shaped and sized sclerites or spinopleural bars on some tergites; ABD TERG II–IV with marginal sclerites; presiphuncular and postsiphuncular sclerites developed; ABD TERG VII–VIII with dark bands (fig. 16).
Body oval (fig. 16). ANT 6-segmented. PT 1.94–2.34× ANT VI b. ANT III with different sized 13–16 sec. rhin. (fig. 24), which are scattered on the outer side along the whole length of this segment; ANT IV with 0–1 sec. rhin.; ANT V with 0 sec. rhin. (fig. 23). Number of hairs on each ANT segment: ANT I 5, ANT II 4, ANT III 6–11, ANT IV 6–9, ANT V 5–6, ANT VI b 3, PT 2–3 (additional). URS pointed, with 2 accessory hairs, its length 0.61–0.72× ANT VI b and 0.71–0.75× HT II. Posterior hair on hind trochanter 0.71–0.91× diameter of trochantrofemoral suture. HTC: 3:3:2. ABD TERG II–IV with 0–1 marginal tubercles, ABD TERG V–VI without marginal tubercles. SIPH as in apterous females. SIPH 4.23–4.64× its width in the middle and 1.11–1.14× cauda. ABD TERG VIII with 2 hairs. Subgenital plate oval, with spinulose imbrications and 2–3 hairs on the anterior disc and 7 hairs on posterior margin. Cauda finger-like, with a constriction in the middle, with 9–10 hairs. Morphometric data are given in Table 1.
Biology. Other morphs and life cycle are unknown.
Distribution. Only known from the type locality in Ilgazdağ, Çankırı Province, Northern Turkey.
