We report on the identification of a new soft gamma-ray source, namely IGRJ20159+3713/SWIFT J2015.9+3715, first detected by INTEGRAL/IBIS and thenconfirmed by Swift/BAT. The source, which has an observed 20-100 keV flux inthe range (0.7-1.4) x 10^(-11) erg cm^(-2) s^(-1), encloses a Fermi variablesource (2FGL J2015.6+3709) and is spatially close to a TeV emitter (VERJ2016+372). Thanks to X-ray follow-up observations performed with the X-raytelescope on board Swift, we have been able to identify the new IBIS/BATdetection with the combined emission of the blazar B2013+370 and thecataclysmic variable RX J2015.6+3711. Both objects show variability in X-rays,with the CV being the most variable of the two. At high energies (above 20 keV)the emission is likely dominated by B2013+370, but the contribution from RXJ2015.6+3711 is not negligible. The blazar emits up to GeV frequencies where itis seen by Fermi, while the cataclysmic variable has a bremsstrahlungtemperature which is too low to provide any contribution at these highenergies. These findings also indicate that the INTEGRAL/Swift source is notassociated with the TeV emission, which is most likely due to the supernovaremnant (SNR)/pulsar wind nebula (PWN) CTB 87.
