Torosaspis turcica Ülgentürk and Kozár sp. nov.

Type data. Holotype female: Turkey, Burdur, Garden of Anadolu Sanat Lisesi, N:37°46 ' 05.50",E:30°33'17.31'', 1047 m altitude, on the needles of Pinus brutia, S. Ülgentürk , 20.viii.2009, coll. No: 2928.

Paratypes: 2 females, and 1 prepupa on the same slide including holotype. Also 3 slides with 19 females, 1 2nd -instar female nymph and 8 1st -instar nymphs labelled: Burdur, Garden of Anadolu Sanat Lisesi, N:37°46 ' 05.50",E:30°33'17.31'', 1047 m altitude, on needles of Pinus brutia, S. Ülgentürk , 22.x.2010, coll. No: 3012.

Adult female: Live appearance: Scale of adult female flat, broadest posteriorly, elongate, oyster-shell shaped, light brown in colour, with two larval exuviae pale yellow and transparent. Scale 3 (2.4–3.7) mm long 0.7 (0.56–0.83) mm wide ( Fig. 1 a). Living female cream in colour, with pygidium darker ( Fig. 1 b). Male test yellowish-brown, parallel-sided, narrower and shorter than female scale ( Fig. 1 c).

Mounted female: Body elongate oval ( Fig. 2), 598 (428–742) µm long and 203 (204–250) µm wide. Body widest across segment I. Body membranous, except for sclerotised pygidium.

Venter: Each antenna with 3 large setae and 2 short conic setae. Anterior spiracles each with one associated trilocular disc pore; posterior spiracles without disc pores. Pygidium rounded, slightly sclerotized, with 2 pairs of lobes. Median lobes with space between them as wide as one of them (length of L1 lobes 29 (23–29) µm wide, space between lobes 33 (21–35) µm wide); (L1) prominent, rounded, outer margin slightly notched. Second lobes (L2) unilobular, similar in shape to median lobes but smaller and not notched; L3 barely perceptible, triangular and finely pointed. Gland spines twice the length of median lobes, each long and slender with a broad base; present as follows: with 2 between median lobes, 2 between L1 and L2, and 3 laterad to L2. Ventral macroducts smaller than dorsal macroducts, present in a submarginal group on segments I and II. Posterior spiracles each with 3 or 4 glandular tubercles and 7 or 8 macroducts in a transverse band extending to margin. Similar macroducts present on submargin of prothorax and mesothorax. Microducts few, present on head and thorax, and with smaller ducts on abdomen. Perivulvar disc pores in 5 groups as follows: 0–3 in median, 5–8 in anterolateral, and 4–8 in posterolateral group.

Dorsum. With 1 marginal macroduct on pygidium on each of segments IV–VII (formula 1,1,1,1). Submarginal macroducts: 2 on segments IV and V each, and 5 or 6 on segments I–III each. Submedian macroducts: 1 on each of segments I–VI. Macroducts also present around submargin of metathorax and with smaller ducts on head, mesothorax and prothorax. Anal opening near anterior margin of pygidium on segment of V.

Comment. This species is characterized in having the following combination of morphological characters: (a) 3 large setae and 2 short conic setae on each antenna, (b) a band of glandular tubercles near each posterior spiracle, (c) unilobular L2 lobes, (d) single marginal macroducts on each of segments IV–VII, and (e) presence of 1 pair of gland spines between the median lobes, 2 between L1 and L2, and 3 laterad to L2. T. turcica resembles T. cedricola comb. nov. in having most of the above characters, but the latter differs in having: (a) only 2 setae on each antenna, (b) bilobed L2 lobes, (c) only 1 gland spine between L1 and L2, and (d) more median and submedian macroducts dorsally on abdominal segments I–III. T. turcica is also similar to T. farsianus comb. nov., both having: (a) 1 marginal macroduct on each of segments IV–VII, and (b) gland tubercles near each anterior spiracle, but the latter species differs in having: (a) L2 bilobed, (b) no perivulvar disc pores, (c) 1 gland spine between L1 and L2, and laterad to L2, and (d) absence of macroducts submarginally on thorax and head.

Etymology. The genus name is formed from Toros (in honour of Prof. Dr. Seval Toros, Ankara, Turkey, a famous lady Turkish aphidologist and entomologist) and aspis, Greek, meaning shield, often used to name members of the Diaspididae .
