HD 85390 has a planetary companion with a projected intermediate mass (42.0Mearth) on a 788-day orbit (a=1.52AU) with an eccentricity of 0.41, for which there is no analogue in the solar system. A drift in the data indicates the presence of another companion on a long period orbit, which is however not covered by our measurements. HD 90156 is orbited by a warm Neptune analogue with a minimum mass of 17.98Mearth (1.05Mneptune), a period of 49.8 days (a=0.25AU) and an eccentricity of 0.31. HD 103197 has an intermediate mass planet on a circular orbit (P=47.8d, Msini=31.2Mearth). We discuss the formation of planets of intermediate mass (30-100Mearth) which should be rare inside a few AU according to core accretion formation models.
