Coenosia attenuata is closely related to C. humilis from which the male is easily distinguished by its entirely yellow femora, antenna and palpus as well as distinctly elongated cercal plate ( Figs 30–31 ). Distribution. Primarily an Old World species, C. attenuata is known to occur across the Palaearctic region and Middle East, including Iran ( Gregor et al . 2016 , Parchami-Araghi et al . 2009 , Deeming 2008 , Pont 1991a , b, 1986). This species has expanded its distribution into the New World where it was first recorded from Ecuador and Peru ( Martínez-Sánchez et al . 2002 ) and later from the USA and Canada ( Hoebeke et al . 2003 ), Colombia ( Pérez-Trujillo 2006 ), Costa Rica ( Hernández-Ramírez 2008 ), Chile ( Couri & Salas 2010 ), Mexico ( Bautista-Martínez et al . 2017 ), Venezuela ( Solano-Rojas et al . 2017 ) and Brazil ( Couri et al . 2018 ).

Coenosia attenuata is increasingly attracting attention worldwide as an effective biological control agent of major greenhouse pests such as whiteflies, leaf-miners, black fungus gnats and small fruit flies ( Couri et al . 2018 ; Pohl et al . 2012 ). It has been successfully reared on fungus gnats and drosophilids under laboratory conditions ( Zou et al . 2017 , Martins et al . 2015 ).
