Leipothrix guangxiensis n. sp.

( Fig. 4 )

Female: (n = 9) Body spindleform, 216 (201–219) long, 61 (59–62) wide, 65 (63–66) thick. Gnathosoma 22 (21–22) long, directed downwards. Dorsal palp genual setae (antapical seta) moderately long and bifurcate. Prodorsal shield 53 (51–54) long, 53 (52–54) wide, shield with frontal lobe; shield design with median line and admedian lines complete, subparallel, with transverse lines at the basal 1/4, 1/2 and 3/4, the 2nd and 3rd transverse lines extending to sides, submedian lines incomplete, broken, with many granules at lateral sides. Scapular tubercles set ahead of rear shield margin, 18 (17–18) apart, scapular setae (sc) 4 (3–4) long, directed central. Coxae with a sternal line; coxal area smooth; 1st coxal seta (1b) 10 (8–10) long, 2nd coxal seta (1a) 22 (21–23) long, 3rd coxal seta (2a) 41 (39–42) long. Leg segments normal, leg I 31 (30–32) long, femur 9 (8–9) long, femoral seta (bv) absent, genu 5 (4–5) long, genual seta (l'') 28 (26–29) long, tibia 9 (8–9) long, tibial seta (l') 3 (2–3) long, set at basal 1/3, tarsus 5 (5–6) long, empodium simple, 4­rayed, solenidion ending as knob. Leg II 30 (29–31) long, femur 9 (8–9) long, femoral seta absent, genu 5 (4–5) long, genual seta 7 (6–7) long, tibia 7 (7–8) long, tarsus 5 (5–6) long. Opisthosoma with middorsal ridge and lateral ridges, dorsum with 58 (56–59) annuli, smooth; ventrally with 98 (96–99) annuli, with rounded microtubercles; Lateral seta (c2) 18 (17–18) long, on ventral annulus 10 (9–10); 1st ventral seta (d) 45 (43–47) long, on ventral annulus 31 (30–31); 2nd ventral seta (e) 10 (9–10) long, on ventral annulus 57 (56–58); 3rd ventral seta (f) 19 (18–20) long, on 7th ventral annulus from rear; accessory seta (h1) present. Female genitalia 17 (16–17) long, 22 (22–23) wide, genital coverflap with 14 longitudinal ridges on posterior half; anteriorly granulated, genital seta (3a) 8 (7–8) long.

Male: not seen.

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 Alocasia macrorrhiza (L.) Schott ( Araceae ), coll. Sui­gai WEI and De­wei LI. Paratypes, 32 females, 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 Leipothrix lysimachiae Hong and Kuang, 1989 , but differs in the shield design with median and admedian lines complete, with transverse lines at the basal 1/4, 1/2 and 3/4; and shield with many granules at lateral sides.

Etymology: The specific designation is derived from the geographic area in which it was collected.
