We present new estimates of redshift-dependent luminosity functions of IRlines detectable by SPICA/SAFARI and excited both by star formation and by AGNactivity. The new estimates improve over previous work by using updatedevolutionary models and dealing in a self consistent way with emission ofgalaxies as a whole, including both the starburst and the AGN component. Newrelationships between line and AGN bolometric luminosity have been derived andthose between line and IR luminosities of the starburst component have beenupdated. These ingredients were used to work out predictions for the sourcecounts in 11 mid/far-IR emission lines partially or entirely excited by AGNactivity. We find that the statistics of the emission line detection ofgalaxies as a whole is mainly determined by the star formation rate, because ofthe rarity of bright AGNs. We also find that the slope of the line integralnumber counts is flatter than 2 implying that the number of detections at fixedobserving time increases more by extending the survey area than by goingdeeper. We thus propose a wide spectroscopic survey of 1 hour integration perfield-of-view over an area of 5 deg$^{2}$ to detect (at 5$\sigma$) $\sim$760AGNs in [OIV]25.89$\mu$m $-$ the brightest AGN mid-infrared line $-$ out to$z\sim2$. Pointed observations of strongly lensed or hyper-luminous galaxiespreviously detected by large area surveys such as those by Herschel and by theSPT can provide key information on the galaxy-AGN co-evolution out to higherredshifts.
