Type species: Tetranychus lintearius Dufour, 1832
3.2. Tetranychus solanacearum Çobanoğlu & Ueckermann sp. nov. ( Figures 1 View Figure 1 –12)
3.2.1. Diagnosis
The female of this new species has a diamond-shaped pattern of dorsal striae between the setae (e1) and (f1). Terminal spinneret on palp tarsus stout and twice as long as broad. Tarsus I with only 4 setae proximal to proximal pair of duplex setae. The proximal setae on tarsus I are not in line with the proximal duplex setae. Tibia I in female with 9 setae (+ one solenidion). All empodia without mediodorsal spurs.
Male’s aedeagus bending dorsally with very small knob and axis of knob almost parallel with shaft axis.
3.2.2. Female (n = 9) ( Figures 1 View Figure 1 –7)
3.2.2.1. Body
Female yellowish green in color. Body length (excluding the gnathosoma) 349 (291–394); body length (including gnathosoma) 469 (392–598); width 279 (231–296).
3.2.2.2. Dorsum
Body setae long and pilose, each seta extending beyond setal base of next setae behind ( Figure 1 View Figure 1 ). Lengths of dorsal setae as follows: Ve 83 (60–100); Sci 136 (115–150); Sce 109 (100–125); c1 120 (100–125); c2 113 (100–125); c 3 94 (80–100); d1 112 (100–125); d2 111 (100–125); e1 109 (100–125); e2 109 (100–125); f1 97 (85–100); f2 85 (75–100); h1 52 (40–70); h2 43 (20–50). Female with dorsohysterosomal striae between setae (e1) and (f1) longitudinal, area between e1 and f1 with transverse striation, forming a diamond shape ( Figure 1 View Figure 1 ).
3.2.2.3. Venter
Striae anterior to genital flap longitudinal, complete to broken medially. Medioventral striae without lobes. Anogenital region with 1 pair of aggenital setae (ag), 2 pairs of genital setae (g1–2), 2 pairs of anal setae (ps1–2), and 1 pair of paraanal setae (h3) ( Figure 2 View Figure 2 ).
3.2.2.4. Gnathosoma
The distal part of peritreme hooked ( Figure 3 View Figures 3–5 ).
Terminal spinneret on palp tarsus stout, broad, twice as long (6.6) as wide (3.2) (ratio of length/width of spinneret: 2.1) ( Figure 4 View Figures 3–5 ).
3.2.2.5. Leg chaetotaxy
As follows (I–IV): number of setae and solenidia (in brackets and not included in setal counts) femora 10– 6–4–4; genua 5–5–4–4, tibiae 9(1)–7–6–7; tarsi 13(1)+2 dupl.–13(1)+1 dupl.–9(1)–10(1). Tarsus I with only 4 pairs of setae proximal to proximal pair of duplex setae; all empodia without mediodorsal spurs ( Figures 5 View Figures 3–5 –7).
3.2.3. Male (n = 9) ( Figures 8 View Figures 8–10 –12)
3.2.3.1. Body
Yellowish to reddish in color. Body length 277 (244–314), including gnathosoma, 356 (327–428). Lengths of dorsal setae as follows: Ve 40 (40–53); Sci 38 (50–57); Sce 77 (78–89); c1 61 (61–80); c2 61 (61–76); c 3 81 (81–89); d1 59 (62–80); d2 55 (60–79); e1 52 (60–75); e2 55 (58–68); f1 55 (44–54); f2 49 (42–60); h1 24 (20–37); h2 30 (21–37). proximal to proximal duplex setae. Empodium I with a mediodorsal spur and proximoventral setae fused to form a spur; empodia II–IV each with 3 pairs of proximoventral hairs and a mediodorsal spur ( Figures 9a–9d View Figures 8–10 , 11 View Figure 11 , and 12).
3.2.3.4. Aedeagus
Knob very small (2.7), about one-fourth of dorsal margin of shaft (11.3), slightly angular anteriorly and pointed posteriorly, axis of knob almost parallel with shaft ( Figure 10 View Figures 8–10 ).
