Tetra sinicae n. sp.

( Fig. 3 )

Female: (n = 8) Body spindleform, 155 (150–166) long, 62 (60–63) wide, 60 (59–62) thick. Gnathosoma 27 (27–28) long, directed downwards. Prodorsal shield 42 (41–42) long, 60 (59–62) wide, shield with frontal lobe, shield design with median line from basal to 2/5, admedian lines incomplete, with 2 transverse lines connecting to median line, 2 transverse lines connecting to submedian lines, 2 submedian lines incomplete. Scapular tubercles set on rear shield margin, 39 (39–40) apart, scapular setae (sc) 6 (5–7) long, directed posteriorly. Coxae with a sternal line; coxal area smooth; 1st coxal seta (1b) 5 (5–6) long, 2nd coxal seta (1a) 10 (9–11) long, 3rd coxal seta (2a) 35 (33–39) long. Leg segments normal, leg I 33 (32–35) long, femur 10 (10–11) long, femoral seta (bv) 8 (8–9) long, genu 6 (6–7) long, genual seta (l'') 20 (18–21) long, tibia 9 (9–10) long, tibial seta (l') 4 (4–5) long, set at basal 1/4, tarsus 6 (6–7) long, empodium simple, 4­rayed, solenidion ending as knob. Leg II 31 (30–32) long, femur 10 (10–11) long, femoral seta 10 (9–10) long, genu 5 (5–6) long, genual seta 8 (8–9) long, tibia 8 (8–9) long, tarsus 6 (6–7) long. Opisthosoma with middorsal furrow, dorsum with 28 (27–30) annuli, smooth; ventrally with 73 (71–73) annuli, with rounded microtubercles. Lateral seta (c2) 25 (24–26) long, on ventral annulus 15 (15–16); 1st ventral seta (d) 44 (42–45) long, on ventral annulus 28 (27–29); 2nd ventral seta (e) 20 (19–20) long, on ventral annulus 47 (47–48); 3rd ventral seta (f) 25 (24–26) long, on 6th ventral annulus from rear; accessory seta (h1) present. Female genitalia 17 (17–18) long, 24 (23–25) wide, genital coverflap with 14 longitudinal ridges, genital seta (3a) 14 (13–14) long.

Male: Body 169 long, 57 wide, genitalia 21 wide, genital setae (3a) 13 long.

Type data: Holotype, female, Jinzhong MT., 37 km SW of Longlin County (24°8 ' N, 105°34 ' E), Guangxi Zhuang Autonomous Region, China, 01­Dec.­2004, from Coriaria sinica Maxim (Coriariaceae) , coll. Sui­gai WEI, Guo­quan WANG and De­wei LI. Paratypes, 18 females and 2 males, with the same data as Holotype.

Relation to host: The mites are vagrants on the under surface of the leaves.

Remarks: This new species is close to Tetra populi Kuang & Zhang, 1999 , but differs in the shield design with median line, admedian lines, and submedian lines incomplete, admedian lines with 4 transverse lines at the basal 1/9, 1/4, 1/3, and 2/3 connecting to median line or submedian lines, coxal area smooth.

Etymology: The specific designation is derived from the specific designation of the type host plant.
