A total of five species were recorded out of which Triclistus aitkini Cameron (1897), Colpotrochia (Colpotrochia) cincta Scopoli, 1763 and Hypsicera intermedia Momoi and Kusigemati (1970) are new records for Pakistan. All the identified species are reported for the first time from Pothwar region in present study. New distributional records of already reported species are added. An Identification key to the genera and their respective species of Metopiinae in Pothwar region of Pakistan has been given. Comparison of recorded species with closely related species, distribution ranges, and remarks on their host and discussion on conservation are provided. Main identification characters of all identified species have been illustrated using microphotography. Spatial distributions of the recorded species have been given using ArcGIS tools. © 2020 Friends Science Publishers Key words: Ichneumonidae; Metopiinae; Pothwar; New country records Introduction contributions in different parts of the world on Metopiinae like Masnadi and Jussila (2009) from Iran, Kolarov and The members of subfamily Metopiinae Forster 1869 are Ozbek (1998) from Turkey, Zhang et al.

Metopiinae are koinobiont (Colpotrochia) pilosa were reported from Pakistan (Townes endoparasitoids of concealed larvae of family Tortricidae et al. 1961; CIBC 1981), whereas, from adjacent countries, and Pyralidae of order Lepidoptera (Gupta 1987). like India 22 species (Townes et al. 1961) Iran 11 species Oviposition takes place in host larva and adult emerged (Amiri et al. 2015) and from China 156 species (Yu et al. from host pupa (Quicke 2015).

Keeping in view this situation and day by day genera and approximately 900 species in all geographical increasing the importance of these bio control agents, regions (Yu et al. 2012; Choi and Lee 2017).
