Necrophilia is also called thanatophobia.
Additionally, criminologist Lee Mellor's typology of homicidal necrophiliacs consists of eight categories (AH) and is based on the combination of two behavioral axes: destructive (offender mutilates the corpse for sexual reasons)  preservative (offender does not), and cold (offender used the corpse sexually two hours or more after death)  warm (offender used the corpse sexually less than two hours after death)
 The sample was divided into genuine necrophiliacs, who had a persistent attraction to corpses, and pseudo-necrophiliacs, who acted out of opportunity, sadism, or transient interest
