Diagnosis. Coenosia tigrina is identified by the presence of a median anterodorsal and a true anterior seta on hind tibia as well as its distinct broad parafacial.

Distribution. It is a Holarctic species that has been recorded from Europe, North Africa, Middle Asia and Middle East, including Armenia, Azerbaijan, Turkey, and Iran ( Pont 2018, 1986, Gregor et al. 2016).

Remarks. Like C. attenuata , the adults of C. tigrina significantly reduce the population of greenhouse pests ( Perron et al. 1956, Hobby 1931) and also attack the larvae of the onion maggot fly, Delia antiqua ( Meigen, 1826) ( LeRoux & Perron 1960, Perron & LaFrance 1952). Larvae of C. tigrina have been observed to feed on the lumbricid earthworm Eisenia rosea (Savigny, 1826) by penetrating the epidermis of their hosts ( Morris & Pivnick 1991, Morris & Cloutier 1987, Yahnke & George 1972).
