Apodiptacus archiboehmerus n. sp

( Fig. 4 )

Female (n = 8). Body spindleform, whitish, 238 (193–254), 70 (63–74) wide, 75 (67–81) thick. Gnathosoma— 45 (43–46), curved abruptly downward. Prodorsal shield— Frontal lobe present, shield covered with wax, 45 (43–47), 50 (47–54) wide; shield line absent. Scapular tubercles set on rear shield margin, 30 (29–31) apart, scapular setae (sc) 16 (13–18), directed forward. Coxae— Coxae І separated, coxal area with short lines; anterolateral setae on coxisternum І (1b) 15 (13–18), proximal setae on coxisternum І (1a) 25 (23–29), proximal setae on coxisternum І (2a) 45 (39–49). Coxigenital annuli fine and numerous, 15. Leg— Segments normal. Leg І 47 (46–48), femur 15 (14–16), basiventral femoral setae (bv) absent; genu 6 (6–7), antaxial genual setae (l'') 60 (53–64); tibia 15 (14–16), paraxial tibial setae (l ʹ) 7 (6–8); tarsus 8 (8–9); tarsal empodium divided, each branch 6-rayed, 6 (6–7), tarsal solenidion knobbed, 6 (6–7). Leg І 42 (42–43), femur 14 (13–15), basiventral femoral setae (bv) 10 (9–12); genu 5 (5–6), antaxial genual setae (l'') 18 (15–22); tibia 12 (11–13), tarsus 8 (8–9); tarsal empodium divided, each branch 6-rayed, 5 (5–6), tarsal solenidion knobbed, 7 (6–7). Opisthosoma— Dorsal annuli 55, with 3 longitudinal ridges and 4 wax stripes; ventral microtuberculate annuli 80. Setae c2 22 (19–24), on ventral annulus 15; setae d 62 (55–68), on ventral annulus 33; setae e 22 (19–24), on ventral annulus 52; setae f 41 (37–46), on 8th ventral annulus from rear. Setae h1 absent. Female genitalia— 20 (19–21), 26 (25–27) wide, coverflap with 19 longitudinal basal ridges; proximal setae on coxisternum ІІ (3a) 10 (8–11).

Male (n = 2). Body 169, 61 wide. Male genitalia— 25 wide, proximal setae on coxisternum ІІ (3a) 11.

Type data. Holotype, female, Mulun National Nature Reserve, Huanjiang County (24°13'N, 108°26'E), Guangxi Zhuang Autonomous Region, China, 16-Aug.-2006, from Archiboehmeria atrata (Gagnep.) C. J. Chen (Urticaceae) , collected by Suigai Wei, Guoquan Wang, Aizhi Qin, Yongjun Meng. Paratypes, 7 females and 2 males, were mounted on 9 slides, with the same data as holotype.

Relation to host. The mites are vagrant on the undersurfaces of the leaves, no visible damage seen.

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

Note. This new species is close to Apodiptacus cordiformis Keifer, 1960 , but can be differentiated by dorsum with 4 wax stripes, tarsal empodium with each branch 6-rayed.
