Natasha Henstridge -- man-eating vet of two "Species" flicks -- has claimed another victim ... filing to divorce her husband of just over 2 years.
TMZ obtained a copy of Natasha's court documents in which she cites ye olde "irreconcilable differences" in her split from Darius Campbell -- a former contestant on England's "Pop Idol" competition.
38-year-old Henstridge and 32-year-old Campbell got married back in March, 2011. The papers state they separated on April 10, 2013.
They have no children together ... though Natasha has 2 kids from a previous relationship.
In her filing, Natasha requests no spousal support be paid ... by either party.
