Gnathosoma 19 (19–25), projecting obliquely downwards, pedipalp coxal seta ( ep) 4 (3–4), dorsal pedipalp genual seta ( d) simple, 6 (6–9), cheliceral stylets 11 (11–20).

Body fusiform, opisthosoma broadest 12 annuli posterior of the prodorsal shield, then tapering regularly until its posterior apex 179 (179–271), 50 (50–70) wide, 53 (50–60) thick light yellow. All type specimens are deposited as slide-mounted specimens in the Arthropod/Mite Collection of the Department of Entomology, Nanjing Agricultural University (NJAU), Jiangsu Province, China.įEMALE: (n = 9). All measurements are in micrometres (µm) and represent lengths, when not otherwise specified. For each species, the holotype female measurement precedes the corresponding range for holotype and paratypes (given in parentheses). Specimens were measured following de Lillo et al. The morphological terminology used follows Lindquist (1996) and the generic classification is made according to Amrine et al. Micrographs were taken at ×100 magnification (×10 eyepiece magnification) with a camera AxioCam MRc attached to the microscope, and connected to a computer, using Axiovision (4.8.2) image analysis software. Specimens were examined with the aid of a Zeiss A2 (Germany) research microscope with phase contrast (A-plan phase contrast objectives: ×10/0.25 (NA), ×20/0.45 (NA) EC plan-NEOFLUAR phase objectives: ×40/0.75 (NA) ×100/1.3 (NA), oil immersion) and schematic drawings were made. They were then slide-mounted with modified Berlese medium ( Amrine and Manson 1996). In the laboratory, the samples including mites were poured into a Petri dish and mite specimens were picked up using a fine pin and placed in Keifer’s Booster to clear them. The eriophyid mites gathered with host plant were placed in vials and stored in 75% ethanol, each vial was marked with the collection data. Sampling was made on the host plants in the field by the aid of a hand lens (30×), in Jilin Agricultural Science and Technology University, Jilin City, Jilin Province, China. Eriophyid mites were found and two new species were identified by the first and third authors. The curled and blistered leaves were checked with the aid of a microscope in the laboratory. worldwide, namely Aceria vitalbae (Canestrini, 1892) (from Clematis vitalba L.), Calepitrimerus clematisis Song, Xue & Hong, 2008 (from Clematis sp.), Cupacarus subnotatus (Nalepa, 1924) (from Clematis recta L.), Epitrimerus flammulae Gerber, 1901 (from Clematis flammula L.), Phyllocoptes atragenes Liro, 1941, Phyllocoptes heterogaster (Nalepa, 1890) (from Clematis recta) (Nalepa, 1891), Phyllocoptes heteronotus Nalepa, 1924 (from Clematis recta), Phyllocoptes monochetus Nalepa, 1924 (from Clematis recta), and Platyphytoptus vitalbae Farkas, 1960 (from Clematis vitalba).ĭuring field surveys in 2015, some leaves were found to be severely curled and blistered (Figure (Figure1). mandshurica, although at least nine species are known from other Clematis spp.

To date, no eriophyid mite species were reported from Clematis terniflora var. It is also known in folk medicine and planted as an ornamental plant in the northeast of China. mandshurica (Rupr.) Ohwi, called “la liao tie xian lian” in Mandarin, belongs to the family Ranunculaceae, and is native to China (Heilongjiang, Jilin, Liaoning, Shanxi, Inner Mongolia), Korea, Mongolia, and the Russian Far East (website of Flora Republicae Popularis Sinicae – and Germplasm Resources Information Network – ).
