description: Doryphoribius qinlingense sp. nov.
(Fig.1 D–F)
Holotype: Adult, sex unknown (slide number Q04/05/004). The type is deposited at College of Life Sciences, Shaanxi Normal University.
Paratype: Four adults (slide number Q04/05/001, Q04/05/002, Q04/05/003, Q04/05/ 005).
Type locality: Qinling mountains, P. R. China.
Etymology: This species is named after the type locality Qinling mountains.
Diagnosis: Cuticle smooth; eyes present; three macroplacoids, increasing in length from first to third, microplacoid and septulum absent; two double claws same in size and shape on each leg, common basal tract well­developed, expanding at the base, principal branch strong with well­developed accessory points, secondary branch relatively longer than the one of other species with three macroplacoids of this genus.
Description of the holotype: A kind of middle­sized tardigrade (Table 1); colorless; cuticle smooth; eyes present; buccopharyngeal apparatus of Doryphoribius ­ type, buccal tube rigid with ventral lamina, peribuccal lamellae absent, buccal armature simple, pharyngeal apophyses present, three macroplacoids short rod­shaped, increasing in length from first to third, microplacoid and septulum absent (Fig.1 D); claws of Isohypsibius ­ type (Fig.1 E–F), two double claws same in size and shape on each leg, common basal tract well­developed, expanding at the base, principal branch strong with well­developed accessory points, secondary branch relatively longer than the one of other species with three macroplacoids of this genus, lunules and other cuticular thickenings absent on the legs; eggs unknown.
. .....continued on the next page * Mn = minimum, Mx = maximum, SD = standard deviation; pt is the percent ratio between the length of a structure and the length of buccal tube (Pilato, 1981).
There was variation in length of the macroplacoids. In all paratypes, the first macroplacoid and the third macroplacoid are almost equal in length, and longer than the second one.
Remarks: There are six species with three macroplacoids in the genus Doryphoribius. Doryphoribius qinlingense sp. nov. differs from all the six known species with three macroplacoids of this genus by having relatively longer secondary branch, average 68.5% with respect to the length of the primary branch, differs from Dor. zappalai Pilato, 1971 by having no lunules; differs from Dor. mariae Pilato & Binda, 1990 in having no dorsal undulations, gibbosities, and a polygonal (non reticular) sculpture; differs from Dor. bertolanii Beasley & Pilato, 1987 in longer claws, secondary branch of the claws relatively longer and not strongly curved, and in lacking dorsal tooth in the buccal armature; differs from Dor. gibber Beasley & Pilato, 1987 in smooth cuticle; differs from Dor. korganovae Biserov, 1994 in smooth cuticle and longer secondary branch of the claws; differs from Dor. turkmenicus Biserov, 1999 by having longer and well­developed secondary branch and basal tract, and by having no particularity in the buccal armature.
