Comments. This cosmopolitan genus is currently composed of approximately 90 species (cf. PÉRICART 1996, YAMADA et al. 2016). Only three representatives are known to occur in Nepal. However, our recent effort has revealed presence of more than ten unknown species; three of them were confirmed to be undescribed and are documented below.

Since WAGNER (1952) the subgeneric classification has been employed for Orius ; currently six subgenera are present, namely Dimorphella Reuter, 1884 (= Paraorius Yasunaga & Miyamoto, 1993 ); Microtrachelia Blöte, 1929 ; Orius s. str.; Heterorius Wagner, 1952 ; Trichorius Yasunaga, 1997 ; and Xylorius Yasunaga, 1997 . Nonetheless, this subgeneric classification system is perfectly applicable only to the Palaearctic species. Further comprehensive revision on a global basis is required to establish more definitive subgeneric classification ( YAMADA et al. 2016). Now twenty species are known from South Asia as listed below; the subgeneric position of five species is yet to be determined.
