Abstract

Apterous and alate viviparous females of Protaphis kvavadzei sp. n. on Eryngium campestre (Apiaceae) and Aphis mat-

ricariae sp. n. on Matricaria sp. (Asteraceae) from Turkey are described. The new species are differentiated from other

aphids colonising these host plants and from species with similar morphology.

Key words: Aphis matricariae, Protaphis kvavadzei, Matricaria, Eryngium, new species, Turkey

Introduction

The genus Protaphis Börner, 1952 is closely related to Aphis, and is represented by 42 species worldwide (Favret 2014). Species of this genus mostly live underground or at ground level on stem bases of Asteraceae, Fabaceae,Campanulaceae and Rutaceae, and are always attended by ants. Their morphology is adapted for this way of life. Although many species of Protaphis are recorded from Central Asia (Kadyrbekov 2001), only two species, P.

pseudocardui Theobald, 1915 and P. terricola Rondani 1847, have hitherto been recorded in Turkey (Görür et al.

2012). A North American species, P. middletonii (Thomas 1879) was previously reported from Centaurea sp. in Turkey (Akyurek et al. 2011, as Aphis middletonii), but was not included in the 2012 list, being based on a misidentification.

The new species Protaphis kvavadzei is here described on Eryngium campestre (Apiaceae) from central Turkey, based on apterous and alate viviparous females collected by D. Hille Ris Lambers in 1977. This species was included as “Aphis (Protaphis) sp. (Turkey, BMNH colln)” in the identification key to apterae of Eryngium-living aphids of Blackman & Eastop (2006, p. 431).

The genus Aphis Linnaeus, 1758 is represented by more than 570 species worldwide (Remaudière & Remaudière 1997; Favret 2014). Most species live on shrubs and herbs, with relatively few on trees. The species belonging to this genus are mostly distributed in the northern hemisphere, with a few native to South America, New Zealand and Australia (Blackman & Eastop 2014). The latest publications about Turkish aphids (Görür et al.

2012; Şenol et al. in press) include 69 species of Aphis, although at least two of these require additional confirmation, as they are North American species never previously recorded in the palaearctic region—A.

carduella Walsh 1863 (recorded as A. helianthi Riley & Monell 1879 in Görür et al. 2012) and A. impatientis

Thomas 1878. The new species Aphis matricariae is here described on Matricaria sp. (Asteraceae) from northern Turkey,

based on apterous and alate viviparous females collected by G. Remaudiére in 1966. Blackman & Eastop (2006), in their key to apterae on Matricaria (p. 641), included this species as “Aphis (Pergandeida) sp. (Turkey; BMNH colln)”.

Material and methods

The specimens of the new species were studied using a LEICA DM LB2 microscope and each morphological character was measured in LAS 4.1 version software. Measurements are recorded mainly in millimeters and listed as ranges. Eighty-two quantitative characteristics were used during species description. Measurements of morphological characters, ratios and chaetotaxy given in this paper are according to Holman (1987), Kadyrbekov (2001), Perez Hidalgo & Nieto Nafría (2004) and Blackman & Eastop (2006).

The following abbreviations of morphological characters are used in the paper: ABD TERG: abdominal tergite; ANT: antenna; ANT I, ANT II, ANT III, ANT IV, ANT V, ANT VI b—antennal segments I, II, III, IV, V, the base of antennal segment VI respectively; ANT III BD: basal diameter of antennal segment III; BL: length of body; BW: width of body; FTC: first tarsal chaetotaxy; HFEM: hind femur; HTIB: hind tibia; HT II: second segment of hind tarsus; HW: head width across the compound eyes; MTu: marginal tubercles; PT: processus terminalis; SIPH: siphunculus; sec. rhin.: secondary rhinaria; URS: ultimate rostral segment.

Alate viviparous females (2 specimens/1 sample)Color in living specimens: unknown. Color on slide: Head and all antennal segments, thorax, rostrum, coxae,

trochanters, SIPH, subgenital and anal plates and cauda brown, femurs brown except basal parts; tibiae pale except brown apices; tarsi brown; ABD TERG I–V with brown intersegmental muscles sclerites; ABD TERG VI with single small spinal sclerite; ABD TERG II–IV with small marginal sclerites; presiphuncular and postsiphuncular sclerites absent; ABD TERG VII–VIII without dark bands (figs. 3, 7).

Body oval (fig. 7). ANT 6-segmented. PT 0.85–0.91× ANT VI b. ANT III with 12–19 sec. rhin., varying in size and scattered on outer side along the whole length of segment (fig. 5), ANT IV with 2–3 sec. rhin. (fig. 8), ANT V with 0 sec. rhin. Number of hairs on each ANT segment: ANT I 4, ANT II 4, ANT III 4–6, ANT IV 3, ANT V 2–3, ANT VI b 2–3, PT 0 (additional). URS pointed, with 2 accessory hairs, its length 1.32–1.43× ANT VI b and 1.08–1.11× HT II. Posterior hair on hind trochanter 0.18–0.28× diameter of trochantro-femoral suture. FTC: 3:3:2. ABD TERG II–VI without marginal tubercles. SIPH and subgenital plate as in apterous females. SIPH 0.43–0.45× cauda. ABD TERG VIII with 6–7 hairs. Subgenital plate with 7–8 hairs on the anterior disc and 14 hairs on the posterior margin. Cauda bluntly conical, somewhat constricted at base, with 16 hairs. Morphometric data are given in Table 1.

Biology. Presumably this species lives on basal parts of the plant and is attended by ants, but no information has been recorded, and a search of the type locality for more specimens in July 2014 was unsuccessful. The life cycle is unknown.

Distribution. Only known from the type locality in Beynam village, Balâ district, Ankara Province, Central Turkey.

Discussion

The new species is placed in Protaphis on account of its short PT, short conical SIPH and short bluntly triangular cauda, but has several distinctive features. Apterous viviparous females of P. kvavadzei differ from the same forms of other Protaphis species by (1) the shape of SIPH: truncate conical but with a broader base than other Protaphis, the sides being distinctly concave towards the base, whereas in other Protaphis the SIPH are truncate conical or subcylindrical without any trace of concavity; (2) SIPH/BL ratio: 0.024–0.035 in the new species, while ranging from 0.035–0.095 in other Protaphis species (with the minimum of 0.035 only in P. ancathiae Kadyrbekov, 2001 and P. chondrillae (Mordvilko in Tarbinsky and Plaviltchikov, 1948); (3) the absence of any pigmented bands or markings on ABD TERG VII and VIII, while these are usually present in at least some specimens sampled from the same colony in other Protaphis; (4) the number of hairs (6–9) on ABD TERG VIII, while this is typically 2–4 (rarely up to 5) in all other species except P. astrakhanica Stekolshchikov, 2005, reported to have 3–7 (Stekolshchikov 2005) and P. ignatii (Gómez-Menor, 1951), reported to have 5–6 (Nieto Nafría et al. 2005); (5) the cauda with a distinct, strongly sclerotised basal constriction. The host association with Eryngium (Apiaceae) is atypical for Protaphis; according to Blackman and Eastop (2006), the only other species recorded from Apiaceae is the very polyphagous Nearctic species P. middletonii.

Discussion

Seven species of the genus Aphis—A. craccivora Koch, 1854, A. fabae Scopoli, 1763, A. gossypii Glover, 1877, A.

nasturtii Kaltenbach, 1843, A. solanella Theobald, 1914, A. spiraecola Patch, 1914, A. vandergooti (Börner, 1933) —are hitherto reported from Matricaria spp. (Asteraceae) worldwide (Holman 2009; Blackman & Eastop 2014).Only one of these species is exclusively associated with Asteraceae plants, A. vandergooti, which lives on roots of several genera of the tribe Anthemideae (Blackman & Eastop 2006). The other six Matricaria-feeding species (A.

craccivora, A. fabae, A. gossypii, A. nasturtii, A. solanella and A. spiraecola) are all polyphagous and live on the aerial parts. Only the apterous viviparous females of A. craccivora, A. fabae, A. solanella have pigmented markings or extensive sclerotisation anterior to SIPH.

Apterous females of the new species can be distinguished from all other Matricaria-inhabiting Aphis by (1) URS/HT II ratio: this is 0.84–0.87 in the new species, while the normal range for this ratio is 0.9–1.6 in the above-mentioned species (rarely down to 0.8 in A. craccivora and A. fabae, but A. craccivora normally has extensive dorsal sclerotisation, and A. fabae has a different ratio of the longest hair on ANT III to ANT III BD: 0.70–3.40 in A. fabae, while 0.61–0.71 in the new species), and (2) SIPH/cauda ratio: this is 0.65–0.80 in the new species, while the normal range for this ratio is 0.8–2.6 in the other Matricaria-feeding Aphis (sometimes down to 0.7 in A. fabae, but as mentioned above that species has relatively longer antennal hairs). Apterae of A. fabae also have a more robust cauda, with rarely less than 10 hairs.

Alatae of the new species can also be discriminated from all the other Aphis species recorded from Matricaria

by their lower URS/HT II ratio, and additionally from alatae of A. fabae by their shorter antennal hairs and fewer caudal hairs.
