During July 2013, field surveys were conducted in Zhangjiajie National Forest Park of Hunan Province. We found three species from the same host
So far, no eriophyoid mite species have been described or reported from
Eriophyoid mites were collected from plants with the aid of hand-lens (30×). Eriophyoids, together with their host plants, were placed in vials and stored in 75% ethanol. Each vial was marked with the following collection data: specimen number, date, host plant species name, colour of living mites, sample location, collector name and relationship of mite to the host plant. Collection data were also recorded in a notebook and examples of host plant parts were kept in a plant specimen folder in a dry environment for further identification and reference.
The morphological terminology follows
FEMALE: (n=11). Body fusiform, 187 (187–200), 61 (55–61) wide, 56 (56–60) thick; light yellow.
MALE: (n=7, dorsal view). Body fusiform, 169–190, 56–63 wide; light yellow.
This species is vagrant on lower part of the leaf surface. No damage to the host plant was observed.
The specific designation “striatilobus” is from the character of prodorsal shield lobe (“lobus”) marked with parellel fine impressed lines (“striatus”), masculine in gender.
This new species is similar to
FEMALE: (n=5, dorsal view). Body fusiform, 198 (186–198), 62 (59–65) wide; light yellow.
MALE: (n=1, dorsal view). Body fusiform, 169, 54 wide; light yellow.
Vagrant on lower part of the leaf surface. No damage to the host plant was observed.
The specific designation
This new species is similar to
FEMALE: (n=13). Body vermiform, 187 (183–192), 60 (55–60) wide, 62 (57–62) thick; light yellow.
MALE: (n=2, dorsal view). Body vermiform, 175–192, 48–54 wide; light yellow.
13 females and 2 males on 15 microscope slides (slide number NJAUAcariEriHN128B.1-128B.15), from
Vagrant on lower part of the leaf surface. No damage to the host plant was observed.
The specific designation
This new species is very similar to
