Type host plant.

Rapanea neriifolia (Sieb. et Zucc.) Mez ( Myrsinaceae )

Other host plant.

Camellia sinensis (L.) Kuntze

Relation to the host plant.

Vagrant. No damage to the host plant was observed.

Type locality.

Nanling National Forest Park, Guangdong Province (24°53'50"N, 113°01'18"E), elevation 1,408 m, 31 July 2012, coll. Qiong Wang, Hao-Sen Li and Jing-Feng Guo.

Type material.

Holotype, single female on a microscope slide (slide number NJAUAcariEriGD21.1; marked Holotype), from Rapanea neriifolia . Paratypes, 4 females and 4 males mounted on separate microscope slides (slide number NJAUAcariEriGD21.2-NJAUAcariEriGD21.9), same collection data of the holotype.

Other material.

10 females mounted on separate microscope slides (slide numbers NJAUAcariEriYN304B.1-NJAUAcariEriYN304B.10), from Camellia sinensis .

Etymology.

The specific designation rapaneae is the genitive case derived from the genus name of the type host plant, Rapanea .

Remarks.

This species is found on the Myrsinaceae Rapanea neriifolia and also on Camellia sinensis . Slight morphological differences were observed between the populations found on the two host species: the population on Camellia sinensis is longer, thinner and with more ventral annuli (62-66) than the population on Rapanea neriifolia which is provided with fewer ventral annuli (52-54). The population found on Camellia sinensis occurred with other eriophyoid species and no males were collected. Current data do not allow understanding if the mite species colonizes regularly and successfully Camellia sinensis and it needs further biological studies.
