Abacarus virosae n. sp.

( Fig. 2 )

Female: (n = 7) Body spindleform, 185 (180–188) long, 52 (51–54) wide, 47 (46–49) thick. Gnathosoma 25 (24–26) long, directed downwards. Prodorsal shield 40 (40–41) long, 50 (50–52) wide, shield with frontal lobe; median line present on posterior 1/2, arrowlike, admedian lines and submedian lines complete, sinuous. Scapular tubercles set on rear shield margin, 30 (29–30) apart, scapular setae (sc) 9 (9–10) long, directed posteriorly. Coxae with a sternal line; coxal area smooth; 1st coxal seta (1b) 5 (5–7) long, 2nd coxal seta (1a) 13 (12–14) long, 3rd coxal seta (2a) 16 (15–18) long. Leg segments normal, leg I 27 (27–29) long, femur 9 (9–10) long, femoral seta (bv) 7 (7–9) long, genu 4 (4–5) long, genual seta (l'') 20 (18–21) long, tibia 5 (5–6) long, tibial seta (l') 3 (3–4) long, set at basal 1/3, tarsus 6 (6–7) long, empodium simple, 7­rayed, solenidion unknobbed. Leg II 26 (26–28) long, femur 8 (8–9) long, femoral seta 11 (10–11) long, genu 4 (4–5) long, genual seta 12 (11–13) long, tibia 5 (5–6) long, tarsus 5 (5–6) long. Opisthosoma with middorsal ridge and lateral ridges; median ridge ending before lateral ridges; dorsum with 40 (38 –41) annuli, smooth; ventrally with 59 (58–61) annuli, with rounded microtubercles. Lateral seta (c2) 48 (45–50) long, on ventral annulus 9 (7–8); 1st ventral seta (d) 50 (48–54) long, on ventral annulus 22 (21–22); 2nd ventral seta (e) 50 (49–54) long, on ventral annulus 38 (37–39); 3rd ventral seta (f) 25 (24–26) long, on 5th ventral annulus from rear; accessory seta (h1) present. Female genitalia 16 (16–17) long, 21 (20–21) wide, genital coverflap with 10 longitudinal ridges, genital seta (3a) 14 (14–15) long.

Male: Body 135 long, 38 wide, genitalia 16 wide, genital setae (3a) 12 long.

Type data: Holotype, female, Tongling Great Canyon, 12 km East of Jingxi County (23°15 ' N, 106°41 ' E), Guangxi Zhuang Autonomous Region, China, 11­Aug.­2004, from Fluggea virosa (Roxb. ex Willd.) Baill. (Euphorbiaceae) , coll. Sui­gai WEI and De­wei LI. Paratypes, 16 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 Abacarus nectandrae Flechtmann, 2002 , but differs in the shield design with median line present on posterior 1/2, coxae with a sternal line, coxal area smooth and female genital coverflap with 10 longitudinal ridges.

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