Description of adult female Appearance in life ( Fig. 1 ). Adult females secrete a thin powdery white wax covering the dorsal surface of their bodies. Living on leaves, flowers and fruits of host plants, commonly attended by ants. Slide-mounted adult female (based on holotype and 5 paratypes ) ( Fig. 2 ): Body oval, 1.95–2.54 mm long, 1.64–2.25 mm wide. Eyes situated on margins, each 42–45 μm wide. Antenna 8 segmented, 340–380 μm long, with 4 fleshy setae each 22.5–25.0 μm long; apical segment 75–80 μm long, 27.5–30.0 μm wide, with apical seta 30–35 μm long. Clypeolabral shield 200–220 μm long, 175–185 μm wide. Labium 3 segmented, 110–120 μm long, 80–85 μm wide. Anterior spiracles each 85–90 μm long, 45–50 μm wide across atrium; posterior spiracles each 95.–115. μm long, 55–60 μm wide across atrium. Circulus rounded-quadrate 80–110 μm wide. Legs well developed; segment lengths for each posterior leg: coxa 160–175 μm, trochanter + femur 145–155 μm, tibia + tarsus 175–180 μm, claw 35.0–37.5 μm. Ratio of length of tibia + tarsus to trochanter + femur 1.16–1.21: 1; ratio of length of tibia to tarsus, 1.2–1.4: 1; ratio of length of trochanter + femur to greatest width of femur, 2.41–2.60: 1; coxa with 30–50 translucent pores; tibia with numerous translucent pores. Tarsal digitules capitate, each 35–40 μm long. Claw digitules capitate, each about 27.5–30.0 μm long. Both pairs of ostioles present, anterior ostioles each with a total for both lips of 28–40 trilocular pores and 4–6 setae; posterior ostioles each with a total for both lips of 58–60 trilocular pores and 6–8 setae. Anal ring about 70 μm wide, bearing 6 setae, each seta 80–90 μm long. FIGURE 1 . Dysmicoccus zeynepae Zarkani & Kaydan sp. n. on: (A) Lansium parasiticum Corr. ; (B) Coffea robusta Lindl. ex De Will ; (C) Manilkara zapota L.; and (D) Durio zibethinus Murr. FIGURE 2 . Adult female Dysmicoccus zeynepae Zarkani & Kaydan sp. n. , holotype. Dorsum. Derm membranous, with 16 pairs of cerarii around body margin, each cerarius with 4–7 enlarged conical setae and 3–5 auxiliary setae. Each anal lobe cerarius set on membranous cuticle and containing 5–7 enlarged conical setae 25–35 μm long, plus 40–45 trilocular pores and 3–5 hair-like auxiliary setae. Dorsal setae flagellate, each 15–75 μm long, scattered throughout dorsum. Trilocular pores, each 3–4 μm in diameter, scattered. Multilocular disc pores and tubular ducts absent. Venter. Setae flagellate, each 30–110 μm long, longest setae located medially on head.Apical setae on anal lobes unusually short, each 80–90 μm long. Multilocular disc pores, each 7–8 μm in diameter, present only immediately around vulva, numbering 8–10. Trilocular pores, each 2.5–3.0 μm across, scattered throughout venter. Oral collar tubular ducts absent. Comments. Dysmicoccus zeynepae is most similar to D. finitimus in having anal lobe and other abdominal cerarii each containing a group of about 2‒7 conical setae. However, D. zeynepae can be readily distinguished from D. finitimus in having: (i) no multilocular disc pores and oral collar tubular ducts on dorsum; and (ii) a few multilocular disc pores without oral collar tubular ducts on venter. It is also close to D. lepelleyi in having small legs and translucent pores on hind coxa and femur, but D. zeynepae lacks oral collar tubular ducts on both dorsum and venter. Dysmicoccus zeynepae is also close to D. castanopseus Williams in lacking oral collar tubular ducts on dorsum and venter; however, it can be readily distinguished by having (character state for D. castanopseus given in parentheses): (i) small, stout legs with tibia + tarsus obviously shorter than trochanter + femur (large legs with tibia + tarsus very slightly longer than trochanter + femur); and (ii) translucent pores on the hind coxa and femur (translucent pores on hind femur and tibia). Etymology. This species is named after Zeynep Kaydan (“mother” of Kaydan’s Laboratory), Zeynep Ģleç and Zeynep Kaya who are good friends of the Kaydan’s lab. Host plants. Durio zibethinus (Malvaceae) , Lansium parasiticum (Meliaceae) , Manilkara zapota (Sapotaceae) and Coffea robusta (Rubiaceae) ( Fig. 2 ). Distribution. Indonesia ( Sumatra I., Bengkulu Province ).
