Genus: Amarochara
Name
Amarochara brevios Assing, 2002 New Canadian Record – Wikispecies link – Pensoft Profile
Material examined
CANADA: ON:Huron Co.,Auburn, hedgerow, pitfall trap, 26.v.2010, A. Brunke, 1 (DEBU), Auburn, soybean field, 23.vi.2010, 1 (DEBU), same data except: 7.vii.2010, 1 (DEBU), 4.viii.2010, 3 (DEBU).
Distribution
Canada: ON; USA: KS (Assing 2002[1]). Native.
Comments
This species is distinguished from other Nearctic Amarochara based on the extremely dense punctation of the abdominal tergites, weak microsculpture of the forebody and shape of the median lobe of the aedeagus in lateral view.
Amarochara brevios was previously known only from the holotype collected in Kansas via flight intercept trap. Here, we report this species from Ontario, Canada based on numerous specimens collected using pitfall and raised pan traps in soybean fields (only 6 specimens kept as vouchers). While Amarochara inquilina (Casey) and Amarochara formicina Assing are associated with mound-building Formica ants, other species of the genus appear to be general inhabitants of decaying litter and only occasionally inhabit ant nests (Assing 2002[1]). Currently nothing is known about the habitat preferences of other Nearctic Amarochara. Based on recent collections of Amarochara in Canada (Assing 2007[2], Webster et al. 2009[3]; this study), species of this genus are poorly collected but widespread across eastern North America and all four Nearctic species are now reported from Canada (see below).
