12. Oligonychus subtropicus Tseng, 1980

Oligonychus subtropicus Tseng, 1980: 147.

Host and distribution.

Juniperus chinensis ( Cupressaceae ); Taiwan.

Remarks.

Oligonychus subtropicus Tseng was described from only females, and details of the male were absent in both the original ( Tseng 1980) and subsequent descriptions ( Tseng 1990; Lo and Ho 1989). Although the author did not specifically compare it with any closely related species, it was differentiated from O. perditus (from Japan on J. communis ) in a diagnostic key, using slight differences in the pattern of dorsal hysterosomal striae ( Tseng 1980, 1990). Moreover, the author did not even compare it with another closely related species, O. chamaecyparisae Ma & Yuan (1976) reported from China on Chamaecyparis pisifera and other Cupressaceae hosts. Bolland et al. (1998) synonymized O. chamaecyparisae with O. perditus and Migeon and Dorkeld (2021) follow this classification, despite it recently being reinstated as valid species by Li et al. (2019). The species identity of O. subtropicus will be clear after collecting and describing the male from the type host and locality.
