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).
