( Figs. 1–6 )

Description

Female: (n = 12) Body fusiform, 205 long, 65 wide, 55 thick; light yellow in color. Gnathosoma 25, projecting downwards, pedipalps with terminal segments very long and enclosing long­form oral stylet. Prodorsal shield 41 long, 45 wide; prodorsal shield with small frontal lobe and some posterior granules; median, admedian and submedian lines present, median and admedian lines form an arrow­like at basal. Dorsal tubercles on rear margin, 35 apart, scapular setae (sc) 10 projecting posteriorly. Sternal line present. Coxal area with short lines; anterolateral setae on coxisternum I (1b) 10, proximal setae on coxisternum I (1a) 20, proximal setae on coxisternum II (2a) 30. Legs I 32 long, femur 10, basiventral femoral setae (bv) 15; genu 5 long, antaxial genual setae (l'') 30 long; tibia 7, paraxial tibial setae (l') 9, setae located 1/3 from dorsal base; tarsus 5 long; tarsal empodium simple, 8­rayed, tarsal solenidion unknobbed. Legs II 30 long, femur 8, basiventral femoral setae (bv) 18; genu 5 long, antaxial genual setae (l'') 12 long; tibia 8; tarsus 5 long; tarsal empodium simple, 8­rayed, tarsal solenidion unknobbed. Opisthosoma dorsally with about 49 microtuberculate annuli, ventrally with about 72 microtuberculate annuli. Setae c2 30 on ventral annulus 15; setae d 50 on ventral annulus 28; setae e 35 on ventral annulus 49; setae f 30 on 5th ventral annulus from rear. Setae h1 4 long. Female genitalia 10 long, 25 wide, coverflap with 12 longitudinal ridges, proximal setae on coxisternum III (3a) 20 long.

Male: (n = 2) 190 long, 55 wide; genitalia 7 long, 18 wide, proximal setae on coxisternum III (3a) 15 long.

Type data: Holotype, female, China: Henan Province, Song county, Tianchishan mountain. July 13, 2004, from Bambusa sp.( Gramineae ), coll. Xue Xiao­Feng. Paratypes, 11 females and 2 males, with the same data as holotype.

Relation to host: Vagrant on leaf undersurface.

Etymology: This new species name is derived from that the species has long pedipalps.

Remarks: The new species is similar to Rhyncaphytoptus cryptomerus Huang, 2001 , but can be differentiated by the coxal area with short lines, prodorsal shield designs and pedipalps with terminal segments very long and enclosing the long­form oral stylet.
