039687B5FFA19B039A51BD3EFC134480.taxon	diagnosis	Diagnosis — This species is distinct from any other known members of the genus in having tibiae I and II with 9 and 8 tactile setae, respectively, and the aedeagus with somewhat triangular shaft and conspicuous pick­shaped terminal knob. It resembles S. zhangi Wang & Cui, 1992 which is known only from females collected in Yunnan, China, on Quercus gilliana Rehder & E. H. Wilson. However, the female of S. gilvus sp. nov. differs from that of S. zhangi in the following points: 1) Tibia II with 8 tactile setae (7 tactile setae in zhangi). 2) Each empodium with 2 dorsal appendant hairs on each of claw­like parts (1 dorsal appendant hair in zhangi). 3) Area immediately anterior to genital flap with longitudinal to curved striae (transverse striae in zhan g i). Female — Body greenish yellow in color, with 2 dark lateral spots on each side. Rostrum reaching middle to distal end of genu I (Fig. 1). Palpus with spinneret about twice as long as broad; dorsal sensillum (solenidion) rod­like, with subparallel sides (Fig. 2). Peritreme L­ or U­shaped distally (Fig. 5). Dorsolateral opisthosomal setae (c 2 to f 2) much longer than dorsocentral opisthosomals (c 1 to h 1); humeral seta (c 3) very long, approximately 3 times the length of c 1; each of c 1 to f 1 shorter than distance to base of seta next behind (Fig. 1). Opisthosomal striae on dorsocentral region transverse, with lobes approximately semicircular. Genital flap with transverse striae; area immediately anterior to flap with longitudinal to curved striae. Numbers of setae and solenidia (in parentheses) on leg segments: coxae 2 – 2 – 1 – 1, trochanters 1 – 1 – 1 – 1, femora 9 – 7 – 4 – 4, genua 5 – 5 – 3 – 3, tibiae 9 (1) – 8 – 6 – 7, tarsi 14 (1) + 2 dupl. – 12 (1) + 1 dupl. – 9 (1) – 9 (1). Tarsus I with 5 tactile setae proximal to proximal set of duplex setae, and 1 solenidion near level of proximal duplex set (Fig. 9); tarsus II with 2 tactile setae and 1 solenidion proximal to duplex setae (Fig. 10). Empodia with 2 dorsal appendant hairs on each claw­like part; the upper dorsal appendant much shorter than the lower (Figs. 13 – 14). Measurements (mean, n = 10): length of body (including rostrum) 526, width of body 284; lengths of setae (mean ± SE): v 2 53.6 ± 0.7, sc 1 52.0 ± 0.5, sc 2 67.4 ± 1.0, c 1 40.5 ± 0.3, c 2 55.7 ± 0.7, c 3 97.3 ± 1.4, d 1 39.3 ± 0.3, d 2 55.1 ± 0.6, e 1 39.6 ± 0.5, e 2 62.2 ± 0.9, f 1 40.4 ± 1.1, f 2 57.6 ± 0.8, h 1 53.8 ± 1.2. Male — Color similar to female. Palpus with spinneret subconical, variable in shape; doral sensillum very slender, subparallel­sided (Figs. 3 – 4). Aedeagus with shaft somewhat triangular, the dorsal and ventral margins nearly straight; terminal knob pick­shaped, about 4.0 long; anterior projection of knob very small, acute; the posterior projection elongate, gently tapering; axis of knob forming slight angle with dorsal margin of shaft (Figs. 6 – 8). Numbers of setae and solenidia (in parentheses) on leg podomeres: coxae 2 – 2 – 1 – 1, trochanters 1 – 1 – 1 – 1, femora 9 – 7 – 4 – 4, genua 5 – 5 – 3 – 3, tibiae 9 (3) – 8 [rarely 7] – 6 – 7, tarsi 13 (3) + 2 dupl. – 12 (1) + 1 dupl. – 9 (1) – 9 (1). Tarsus I with 4 tactile setae and 2 solenidia proximal to proximal set of duplex setae, and 1 solenidion near level of proximal duplex set (Fig. 11); tarsus II with 2 tactile setae and 1 solenidion proximal to duplex setae (Fig. 12). Empodium I with 1 or 2 dorsal and 1 ventral appendant hairs on each claw­like part (Figs. 15 – 16). Empodia II – IV similar to those of female. Measurements (mean, n = 10): length of body (including rostrum) 437 (425); lengths of setae (mean ± SE): v 2 40.1 ± 0.6 (37.9), sc 1 38.7 ± 0.8 (37.3), sc 2 49.2 ± 0.7 (48.0), c 1 31.3 ± 0.6 (28.0), c 2 44.5 ± 1.5 (38.7), c 3 73.2 ± 1.2 (74.3), d 1 32.1 ± 0.7 (30.6), d 2 43.9 ± 1.1 (38.7), e 1 30.7 ± 0.6 (27.7), e 2 39.7 ± 1.3 (33.8), f 1 30.0 ± 0.7 (28.4), f 2 32.8 ± 0.7 (31.6), h 1 27.8 ± 0.7 (26.5).	en	Ehara, Shôzô, Ohashi, Kazunori (2005): A new spider mite species of Schizotetranychus (Acari: Prostigmata: Tetranychidae) from Quercus gilva in Japan.
