description: Cenopalpus bagdasariani (Livshitz & Mitrofanov 1970)
(Figs 71–81)
Brevipalpus bagdasariani Livshitz & Mitrofanov 1970: 789.
Diagnosis. Prodorsum and opisthosoma with dorsocentral and lateral rugose ridges, separated by reticulations. Dorsal body setae broadly lanceolate and strongly serrate. Venter smooth with patch of reticulations laterad 4a. Ventral and genital shields with few striae and reticulations, anal shield more strongly reticulate. Dorsal setae on femora I–II broadly lanceolate and strongly serrate, and on genua I–II narrowly lanceolate and serrate. Spermatheca a long slender tube, terminating in round bulb.
Female. Dimensions: Length of body excluding gnathosoma 274–289; width 132–146, length of gnathosoma 85; Legs: I 135; II 125; III 118; IV 133; setae: v2 36; sc1 37; sc2 31; c1 26; c2 23; c3 31; d1 15; d3 19; e1 13; e3 18; f2 20; f3 19; h1 18; h2 11.
Dorsum (Fig. 71). Both prodorsum and opisthosoma with dorsocentral and lateral rugose ridges, separated by reticulations. Dorsal body setae broadly lanceolate and strongly serrate. Prodorsal projection deeply notched (notch not reaching setae v2), forming two broad triangular lobes, with small lateral lobes.
Venter (Figs 72 – 73). Venter smooth with reticulated patches lateral to setae 4a; ventral and genital shields with few striae and reticulations, but anal shields strongly reticulate. Setae 4a much longer than 3a. Aggenital setae smooth; genital (g1–2) and pseudanal setae (ps1–2) weakly serrate; setae g2 inserted slightly anterior to g1. Spermatheca a long slender tube terminating in small round bulb.
Gnathosoma (Fig. 74). Infracapitulum reaching middle to anterior margin of genu I. Palp four-segmented; palp tarsus with two eupathidia and a seta, tibia with two setae, femorogenu with one seta and trochanter without setae.
Legs (Figs 75–77). Counts of setae and solenidia (included in counts) on podomeres of legs I–IV: coxae 2-2-1- 1, trochanters 1-1-2-1, femora 4-4-2-1, genua 3-3-1-0, tibiae 5-5-3-3, tarsi 9(ω)-9(ω)-5-5. Leg chaetotaxy as follows: trochanters I, II, IV v’; tr III v’, l’; femora I–II d, v’, bv”, l’; fe III d, ev ’; fe IV ev ’; genua I–II l’, d, l”; ge III l’; ge IV nude; tibiae I–II d, l’, l” v’, v”; ti III–IV d, v’, v”; tarsus I–II u’, u”, p’, p” tc’, tc”, ft’, ft”, ω; ta III–IV u’, u”, tc’, tc”, ft’. Dorsal setae on femora I–II broadly lanceolate and strongly serrate, and on genua I–II narrowly lanceolate and serrate.
Male. Dimensions: Length of body excluding gnathosoma 215; width 108, length of gnathosoma 62; Legs: I 128; II 122; III 110; IV 116; setae: v2 33; sc1 35; sc2 36; c1 28; c2 25; c3 31; d1 21; d3 40; e1 16; e3 39; f2 36; f3 37; h1 12; h2 27. Body tapered posteriorly with transverse striae between d and e setae. Prodorsum and dorsal body setae similar to that of female, though some longer. Aedeagus long, gradually tapering towards anal opening. Leg chaetotaxy similar to that of female, solenidia on tarsi I and II similar to that of female. Coxae III–IV also flanked by longitudinal slits.
Deutonymph (Figs 78 – 81). Dimensions: Length of body excluding gnathosoma 249–250; width 132–142, length of gnathosoma 60–68; Legs: I 102–105; II 98 –99; III 85 –89; IV 85 –94; setae: v 2 31–33; sc 1 30–34; sc 2 30– 31; c1 38–39; c 2 26–29; c3 36; d1 33; d3 36–38; e 1 10 –14; e3 32 –35; f 2 30–34; f3 35–36; h 1 30–32; h2 7–9. Dorsum similar to that of female, except most setae longer, especially posterior setae, setae h2 five times longer than h1. Venter completely covered with mainly transverse striae, one pair of setae 1a, 3a and 4a, one pair of aggenital, one pair of genital and two pairs of pseudanal setae, most slightly serrate. Gnathosoma similar to that of female. Leg chaetotaxy only differs from female in that trochanter IV is without setae.
Remarks. Our Turkish specimens resemble C. bagdasariani in all respects, except for having an ornamented ventral shield, depicted as smooth in the original description (Livshitz & Mitrofanov 1970). Meyer (Smith) (1979) referred to the dorsal ornamentation as “irregular” and Livshitz & Mitrofanov (1970) described it as “folds form a reticular design consisting of multiangled cells and prodorsal shield smooth dorsocentrally”. The Turkish specimens fit these descriptions. These specimens also resemble those of C. pennatisetis Wainstein 1958 and even share the same genus of host plant (Populus, Salicaceae); however, the latter has large polygonal cells mediolaterally on the prodorsum and anteromedially on the opisthosoma (Wainstein 1960; Mitrofanov & Strunkova 1979). The mediolateral prodorsal cells are smaller in C. bagdasariani and the opisthosoma is smooth anteromedially. The deutonymphs collected with the female Turkish specimens also resemble those of C. pennatisetis; however, C. bagdasariani deutonymphs differ from those of C. pennatisetis in that the dorsal setae are broadly lanceolate in C. bagdasariani instead of narrowly lanceolate in C. pennatisetis, and setae c1 are clearly shorter than the distance c1-d1 as opposed to as long as or slightly longer than this distance in C. pennatisetis. A spermatheca is described here for the first time and may confirm this identification in future.
