Subgenus Orius Wolff, 1811

Diagnosis

Recognised by a combination of the following characters: pronotum highly polished, impunctate, sparsely covered with setae, with long, stout setae near anterolateral and posterolateral corners and a pair of similar setae behind ocelli, with distinct collar and

convex callus; ostiolar peritreme usually with wide and smooth area anterior to median furrow. Detailed diagnostic characters were provided by Péricart (1967, 1972).

Remarks

Four species occur in India and one species occurs in Japan (Muraleedharan 1977; Yasunaga 2001). This subgenus is recorded from Thailand for the first time.
