Aradus depressus (FABRICIUS, 1794) ( Figs 1, 4-7 )

M a t e r i a l e x a m i n e d: BRITISH COLUMBIA: 1♀, Port Coquitlam, backyard MV, 49.2441620°N 122.778125°W, 850m, 5.v.2014 ( Dave G. Holden ) [ UBCZ].

A Palaearctic species, most probably introduced. The species is keyed and illustrated by HEISS & PERICART (2007) and is the most widespread flatbug in Europe reaching the Russian Far East territories, but is not yet recorded from Japan ( HEISS 2001). A. depressus is easily recognizeable by its small size, anterolateral angles of the pronotum that are pale, and the stout rather short antennae.
